coast concordia and cheerful

ours are simple speculations of simple spectators, so much to deceive the expectation of the moment when the true destination of the wreck will be communicated.
I think that this must end its career above or under water, but in the nearest demolition yard and as soon as possible. However...it is not to be excluded that some brilliant minds jump out with some extraordinary idea so much to strabilize the masses and perhaps, we find the carcass reassembled as a day center in Piazza del duomo a milano (it is long enough the square?) or become supermarket in miami.

p.s.
exatem, 30/40 m. underwater and a large hotel in the dead work outside the water? maybe off the rock or fox?:biggrin::biggrin:

from Monday the balloons/surgents of our Navy begin to enter the wreck for safety operations and know very well that it will not be a risk-free enterprise.
If she was sunk for the joy of amateur divers, you know how they would gongle funeral pumps. . .
a ship of 300 meters, with 1500 cabins and who knows how many other premises, is a maze worthy of the best teseo.

All the ship is not, but maybe a party.. .
Moreover, many abandoned industrial areas have become very interesting technological museums, which have allowed at least to recover the costs of safety in the area.

I could agree if the ship represented an example in the history of the marinery or was a unique specimen of boat such as to constitute a point of reference in naval architecture or had completed some glorious venture.... but of ships so there are hundreds around the seas, larger, more beautiful uglier. are all like las vegas grand hotels, if you know the place you will understand the similarity: made to fill the eyes of the users and the pockets of the owners and to last to the maximum 25 years then demolished and rebuilt to always offer something new to the players. On the other hand, one of the most profitable sources on board cruise ships is the casino. As for the transformation costs in museum or similar and management costs, I would be curious to know what makes the queen mary moored to miami (I think) and transformed into a hotel. It would be interesting instead, to know if there is a possibility of recovering at least part of the furnishings, which significantly affect the cost of a ship of this type and perhaps, something could be reused after a verification of the convenience of recovery.
 
a curiosity.

I understand that they are confidential, but someone has a more or less approximate idea of the time de roi (return of investment) of these great cruise ships? except shipwreck of course.
 
the operations of the lily have demonstrated, if necessary, how the race to the gigantism of the ships from cruise makes the intervention operations in case of an extremely complex and difficult accident, both for the quantity of people to be taken safely, and for the successive works of reclamation of the marine areas concerned. It is interesting to see how and for what reasons it has come to build such large and unfortunate ships, huge floating boxes very “kitsch” and very little elegant, which little have to marinate in the romantic sense of the term, children exclusively of the unbridled race in search of profit.
but fortunately in the history of the marinery, it was not always so.
there was a period in which important technical acquisitions involved a profound renewal in naval architecture. the 1930s determined a radical evolution that was expressed with the design of the transatlantic “bremen” (1929). Bremen.webpBremen2.webpthe bremen, along with the twin Europe, presented numerous surprising innovations among which the most evident was the aerodynamics of the superstructures. ships of 52.482 tons of displacement, had a motor apparatus consisting of 4 groups of turbines more turbine back, than with the speed of 28 knots and a half allowed the bremen to win in 1929 the blue ribbon (a company repeated in 30 and 33 from the twin unit). a well-known architect lived from 1887 to 1967, tasted final pulitzers, whose notoriety convinced the greater state of the marine direction to commission the furnishings of the most prestigious military units of the time (between 1933 and 1940 pulitzer takes care of the preparation of the control rooms, the common rooms and the houses of the officers of the battleships, cauliur, victory veneto and, andrea doria, (in these occasions he wrote great use <<e’ anche="" bellezza="" bremen="" che="" consenso,="" coscienza="" costante="" critica="" delle="" dello="" di="" dopo="" e="" elementi="" esterne,="" estetica="" estetico”…="" gli="" il="" in="" insegnamenti="" la="" l’europa="" nave,="" nella="" noi="" nuova="" opposti="" presenza="" prima="" questa="" ricche="" rivelando="" scafo="" sentiamo="" sono="" strutture="" trattandosi="" trovarci="" tutti="" un="" una="" volta="" “fatto="">>.
the bow tilted forward, slightly rounding to the mascone (remember that with the term mascone we mean the surface straight, mascone straight, or on the left, mascone of the left, of the bow of the ship where the waves break) and above all the low and smoked "syagomnic elongated, they were for the absolutely revolutionary era (just compared the images with the previous " the time required futuristic configurations to underline the characters of progress and modernity and the bremen responded to these needs indeed, went beyond, so much so that initially, excluding the round stern and the low fumaioli, the ship did not have an immediate follow-up because considered excessively modern. the first ship to grasp its architectural significance was the Italian motorship “victoria” built in Trieste in 1931. even if a little less bold, the design of the victoria blended modernity with the harmony of Italian style so that it appeared more graceful and harmonious, well balanced between full and empty. the modern proposals of the bremen were translated by the designer of the victoria, nicolò costanzi and the "study stuard" of pulitzer, in more comprehensible and accessible solutions so as to open a completely new cycle so that, initially intended to operate on the celery line between trieste and anlessandria of egitto, was later transferred on the most prestigious one of the india and extreme east where it stood out as the particular English </e’>VICTORIA.webpthe motorship victoria was considered the most beautiful passenger ship built in the period between the two wars, not only in Italy but all over the world, both for its slender forms and the perfect harmony of the superstructures, both for the white color of the hull with the elegant blue band at the height of the deck both for the two low light yellow chimneys; was defined in the eastern ports and travellers as “white arrow of the Mediterranean”, “column of the ocean”, “white dove of the East”, “fresh of the Indian Ocean” and “nave of the Marajà”.
now the adoption of aerodynamic superstructures, of prues tilted forward, also extended to the merchant ships and to this contributed the French transatlantic "normandie" from 80.000 tons, the first conceived with a design of extreme cleanliness and elegantly finished, that formed a new generation of naval architects. Normandy, in addition to the wealth of the interior, had the innovative feature of the electric propulsion that however proved poorly reliable. Normandie.webp
 
Then there was war and if on the one hand the production of luxury ships stopped, on the other a considerable amount of solutions were available for military needs. the new course was born from a remarkably advanced starting point compared to when the previous one closed. the resumption of the constructions of fleeting ships of a certain size founded its roots on a glorious past enriched by a huge baggage of new technical solutions. He initially tried to combine the rounded lines of the bremen and the victoria with the scheme to a single smoker of the “saturnia” trying to draw the best from both patterns. SATURNIA.webpfrom this union, the “julium cesare” was born, which represented a net gap with the past due to the modern style adopted and whose most evident aesthetic characteristic was represented by the huge fumaile placed at the top of the hull almost as if with its mass, had determined the curvature of the hull. this feeling was accentuated by a colorful band painted on the walls that climbed towards prora that brought the eye to the slender and high prora on the sea instilling a feeling of great dynamism. the seaboard acquired a dominant aesthetic role as it had been at the time of clippers, the very fast ships of the previous century. the stern mirror was roundish, similar to that of the cruisers and the superstructures, constituted by ten bridges, gradually degraded towards the stern. the style of the ship made it look like a yacht and made the profile thin, making the figure as a whole light compared to the actual size. Giulio_Cesare_1.webpthe structure of the hull was divided into twelve ponds which, according to the norm of the London Convention of 1948, had to guarantee the floatability of the ship even in case two adjacent compartments were flooded.
the cesare julius represented a mandatory reference model and to it were inspired the successive “andrea doria” (1951), “colombo” (54) and “da vince” (59). ships in which the continuity between hull and superstructure was realized and above which, the smoke was erected which, in spite of its function, assumed the appearance of a real superstructure, agreeing with the rest of the ship also in proportions. The Doria andrea had been launched on 16 June 1951 in the Ansaldo shipyards of the West Sestri Genoese and represented the pride of a nation that was defeated and humiliated by the world conflict, trying to rebuild an international reputation. was not the largest (superied by the queen elizabeth), nor the fastest (battuted by the united states); it was not designed to compete in size and speed but to bring the message of the incomparable artistic beauties that Italy could offer. It was supposed to be the most beautiful and the most luxurious. andrea doria.webpnicknamed the “big lady of the sea” the goria was a floating museum, with paintings, tapestries, statues, ceramics and other wonders. A million dollars was spent in decorations and works of art distributed in the booths and public rooms, including a natural-size statue of the admiral Doria. three swimming pools, lounges, four cinemas, air conditioning system, tennis court, basketball, pitch shooting or the target were available to all passengers and not only those of first class.
the “france”, set in 1957 and launched in 1962, repeated the design already experimented with the Normandy and the lines were the most possible continuous and clean.

but a further evolution was mature. the turbonave “southern cross” of 1954, as a result of the positioning in the stern of the machines, proposed a new distribution of the superstructures with the positioning of the fumaiole in the stern districts. this solution found further confirmation in the “rotterdam” of 1958, where the fumaioli were similar to a traliccio, and in the “canberra” of 1960.
in Italy it was costly, which we have already met before, defined a new concept: the “wave seat” and consequently a new concept of bow. with the term “wave seat” it was indicated a longitudinal recess obtained in the prora whose sections are returned and concave in the float, and then became convex both above and below that area. with this conformation you get a sort of crib in the whole area of famine wet by the wave generated by the ship in motion. this solution improved the penetration of the hull with reduction of the ondous form and therefore reduction of the famine resistance. the "galileo galilei" and the "guglielmo marconi" were distinguished precisely for the game of curves of the bow "to a narrow spoon" that is from many still considered unsurpassed model of elegance and slenderness of the lines.
This new prora was then exalted in the 1963 “oceanic” and even more, in the “eugenio c.”, set on 4 January 1964, where it assumed an increasingly characteristic and distinctive role of the ship defining the aesthetic imprint of the whole ship. the eugenio c had over a prora characteristic called "swan neck", a pair of retractable stabilizers "denny-brown", air deflectors to protect the discovered bridges, the propulsion was entrusted to two turbulent groups "crda - de laval" from 60,500 hp for a speed of 28 knots. here also a particular attention was reserved to the design of the two fumaioli placed in the poppiera area, they had a characteristic shape to minimize the fall of fumes and dust on the bridges. the whole ship was a continuity game, with the walls as smooth and naked as possible. the search for pure and continuous forms, required the accumulation of air outlets, crates, corridors, etc. etc., the concept of “carrozzeria casio” was developed, then relaunched even more strongly, from the “france” and the canberra”.

the family tree of the transatlantic ends with the “queen elizabeth ii” of 1967. after subsequent processing would have been dictated by service economy, maximum embroidery and rational use of spaces, in short, the exploitation of the volume offered by a regular parallelepiped. so the structure came away transforming itself into a sort of “box”, with high and square walls, with straight and flat lines. the first ships to approach the concept of “box” were the “car-passenger-ferries” and the “ro-ro ferries”. this technical exasperation has led to a change in the proportions between length, width and height with increase of the last two also to the detriment of the nautical performance that however, had already lost the battle of the velocistic performance on the ocean crossings. the different relationship between the three dimensions, the propensity to square the volumes, the advancement of the superstructures, they removed from the aesthetic tradition. now the risk was to get weighted and unfortunate forms.
in the “song of norwey” and in the “royal viking star” respectively of 1960 and 1972, the shift towards the bow of the prodier districts, involved, in the need to preserve a sufficient reserve of thrust to prora, the adoption of exasperated forwards of the prodier profile that also have the advantage of offering to the silhouette a dynamic footprint. as in all things, there are those who “take their hand” and exaggerate, for example in the “song of norway” the gigantic fumaiolo compromises the “correctness” of the lines. the song of norway was the first ship of the royal caribbean cruise line founded in 1968.
after four years of success, the song of norway became the first passenger ship to undergo an elongation process: a section of about 26m was inserted in the middle of the vessel. Considering the success of this procedure, the nordic prince was also extended in 1980.


from this moment on the passenger ships increased their size and if you think that the same titanic, marvel of technology and immense ship in 1912, today would not enter the ranks of the 50 largest ships of the world, ranking that sees to the command the “oasis of the seas” and the twin “allure of the seas” always owned by the royal caribbean international, you can make an idea of the development reached. 361 meters long, have a maximum width of 66 meters and 72 meters high. their gross tonnage is 225.000 tons. up to its capacity, it can accommodate 6,360 passengers as well as 2,100 crew members. the ship have 18 bridges, of which 16 passenger bridges and 2.704 cabins. the michelangelo and the raffaello stazzavano 45,933 tons, of the moscerini in comparison also to the "peaceful Coast" that is of 114.147 tons, which is just a little more than half of the oasis of the seas.
in the last image the ms allure of the seas passes under the bridge of storebælt, which connects the islands of funen and zealand in Denmark, with a margin of 1.5 and a half regarding the edge of the infrastructure
Allure of the seas.webpAllure.webp

Nice disamina, thank you.
really beautiful ships, what masterpieces!
and that sadness this kind of condos from traveling suburbs! you should return to those aesthetic, and dimensional canons, with current technologies, an operation at mini, 500, or ww beatle to understand us.
apart from the gorea doria of course, you know what happened to these ships? all in demolition, or any of the most beautiful of the late 1960s is still in navigation?

ps- I'm taking a look... what a shame you win burned and on a side!
cesare julium and demolished colombo.. and the victoria has been siluted!
 
a curiosity.

I understand that they are confidential, but someone has a more or less approximate idea of the time de roi (return of investment) of these great cruise ships? except shipwreck of course.
It’s not about topics that I know for which I threw out some internet even though I couldn’t recover much information.
I refer to what I have found that we should perhaps turn to the management control of a company but I do not think that I release this information easily. However some data on which to reason I found it.
if as amortization you want to determine in how many years the company will manage to cover the investment the calculation is anything but simple.
In general, the fiscal amortization, which begins from the exercise of income according to the good, occurs within 10 years (the amortization quotas of the properties, plants, machinery and other mobile goods are deductible from the tax period in which the asset is used according to the rate set out in the ministerial table indicated in d.m. 31/12/1988).
but this is not valid for all the value of the ship.
furnishings, kitchens, management software, have a shorter life (about 5 years) also, there are extraordinary maintenance expenses.

to give some number we take for example the fantasy msc (and then the harmony).
msc fantasy: MSCFantasia.webp133.000 tons, an area of 450.000 square meters, 333 meters long, 67 meters high. can accommodate 4,000 passengers in addition to a crew of 1,350 people, the ship has 16 bridges, 25 lifts two swarovski crystal stairwells, Murano glass skylights, 5 restaurants, 19 bars, 5 pools, wellness area, 1.637 cabins, 65,000 light points, 1,800 kilometers of electronic wiring, 12 hydromassage tanks, 150 fountains and water jets. all this cost a little more than 400 million euros.
calculating a depreciation time of 15 years you get an annual cost of 26 million euros to which you have to add interest for mortgage contracts that could vary the costs significantly at least a 7-8% per year.
the crew as said is 1350 people whose most low cost, however, is always around an average salary of about 1000 euros per month which, calculated on thirteen monthly, amounts to about 18 million euros per year to which the contributions and insurance charges are added for an additional 30-40% and a total of 6 million that lead to 24 the management costs of the staff.
You must then eat and drink the 4,000 passengers and the 1300 crew members for an amount of 10-15 euros per day per person (on so important numbers the food costs are around this figure) for about 2 million euros per year. 2 million more go for services like sheets, towels, flowers and more.
there are then the parking costs in port ranging from ground transport (pullman, charter etc.) to mooring costs (pilot, any trailers, moorings , luggage bundle) cost of dock etc... are very variable figures also seen that some make false cards to have a cruise ship.
the management costs of the company as: advertising, tourist agents, taxes, taxes... (although often they use so-called tax havens).

insurance costs. generally the ships like the concord are ensured “at body” the insurance that covers the entire value of the ship, value considered immutable where it is not taken into account wear.
in particular the concordia is assured with the American aon insurance that in Italy is represented by changed genova risso for a value of 500 million dollars (the concord has cost 510 million) in the face of an annual award equal to 0.15% of the guaranteed value therefore, approximately 600,000 €. for assurances of similar amounts are multi-brand pool.in this case are part of the general insurance, rsa insurance, lloyd’s.

I left the fuel for the last time. the fantasy has a thermoelectric plant from 40 mw and calculating a production cost of about 10 -15 cents per kw/h, optimistic and very variable given depending on the fuel prices, determine a hourly cost of 100-150 € now for megawatts for which in a year are about 35-40 million. In reality consumption should not be calculated as often the ship is firm and in any case never navigates to the maximum power so the figure can be reduced to 20-25,000,000.
the concordia instead had 6 diesel engines wartsila model 12v46c from 75.600 kw (you can see them here): http://www.wartsila.com/en/engines/medium-speed-engines/wartsila46#_0_references__undefinedThese are very efficient engines considering the relationship between consumption and power, but they are also very polluting engines because they use raw fuel and rich in pollutants. 13.8 tons per hour (from the engine consumption curve) are consumed in navigation, which in one year makes 120.888 tons equal to the annual production of falconara refinery.
here the topic is spiny because it touches environmental issues (just think about the amount of oxygen aspired by the atmosphere to burn all that fuel) that we can talk about on other occasions.

"the "oasis of the seas" and the twin "allure of the seas" always owned by the royal caribbean international, you can make an idea of the development reached. 361 meters long, have a maximum width of 66 meters and 72 meters high. their gross tonnage is 225.000 tons.

when you indicate the width you mean the maximum however on the big super tankers to go back and forth from bow to stern use the bikes!

p.s. I don't want to do the "precise", but for correctness, they are called "plank wings".

given the tamarraggine of those ships I would say that they will be equipped as a minimum of means like these:2.webp1.gif
 
I had four accounts:
- msc fancy, cost 450.000.000 $ for 2.000 cabins, cost per cabin = 225.000 $
staff boarded 1200/1300, between crew and hotel.
- hotel mirage, las vegas, year 1989 cost $65,000,000 per 3,044 rooms, room cost $213,000.
We should report to the dollar in 1989 today.
1.500/2.400 employees (1 every 3/4 rooms + casino)
the owner of this hotel has refunded the loan in 18 months.
I don't think a cruise ship can do the same.

a necessary desertion from the purely technical discussion.
I'll pass it as I read it.
were found the remains of the two missing of the shipwreck of the concordy coast of January 2012 to the island of the lily. to be sure that it is the bodies of russell rebello and maria trecarichi grace, however, awaits the outcome of the examination of the dna.
the news has been communicated by the structure of the commissioner delegate explaining that this morning, during the research activities carried out at sea in correspondence of the central zone of the ship, the divers of the Coast Guard and of the finance guard "have identified some remains whose nature must still be defined through the DNA test".

in short, will begin the activity of repertation by the specialists of the Carabinieri of ris to arrive to the identification
were informed the family members of the two missing in addition to the prosecutor of the republic.

to the island of the lily was the same head of civil protection Franco gabrielli to give the announcement: "remains were found in the part of the wreck that the team of coastal guard divers, military navy and firefighters identified as one of the most interesting targets. remains that could be referred to the people we are looking for. we have warned the relatives and in the next few hours will intervene the ris of the carabinieri in order to make sure and arrive to the sure identification".

According to what has been learned, the discovery was carried out near that area indicated on the search maps as "area 3 of the ship center", an area near the bridge 4 where it was assumed that the two dispersed at the time of the shipwreck. diving had begun at 10 am and ended at 12 pm. once detected, the remains have not yet been recovered: The Prosecutor has immediately been informed that he has prepared the recovery and assignment to the exam ris. In the next few hours the divers will then make another dive to bring back the bones.
 
the question about the costs posed by hunter, to which I tried to answer without great success, has “solleticato” and pushed to deepen the topic. who knows me knows that if stressed, I hardly give up the first difficulties. Thus, once the responsibility of those who have me, so to speak, triggered, survivor this new disgression on the great ships from cruise, detestate but at the same time ambite (for some), floating oasis of pleasure. the development of faster transport systems of the ship, (airplane, train, car) if on one side has reduced the amount of goods transported for the short routes (the so-called cabotage), on the other has not prevented the increase of the volume of the goods transported internationally.
still today most of the handling of the goods from and for our country happens through ships. next to the traditional areas of marine transport then developed sectors linked to the cruises that gave an additional impetus to the field. the cruise had the merit of representing a stimulus to consider the ship not only a means of transport but also a place of holiday and leisure.

the history of the fleeting ships begins in the middle of the 1800s with the opening of the translatlantic navigation lines but is with the beginning of the xx century that the ship assumed the role of main means of connection between the two shores of the ocean. in this period the naval industry was pushed to try to improve the speedy performance by the need to use specialized carriers in passenger transport, creating a stable connection between Europe and America. This was the age of the great, fast transatlantics, a dominance lasted until the middle of the 60s, when the areo was established as a means of transport of fast and economic mass. the performance of the aircraft closed the era of the “white snow” penalizing an industrial sector that much had invested in the search for increasingly fast and comfortable solutions. at that time Italy, thanks to its production capacity, had assumed a role of great international prestige. there were ships that made the history of maritime navigation:
– the rex, which won the blue ribbon in 1933;
- the count of savoy, one of the most elegant and luxurious ships of the 1930s;
- the saturnia, with its profile and the propulsive system of avant-garde, then unique in the world ( diesel engines at 2 times in place of traditional steam turbines);
- the oceanic, known for the particular technical and architectural solutions (it was the first ship inspired by the concept of holiday-cruise rather than the one of the line transport);
- the Michael twins and a gutter.
of others we talked in previous posts.
As a result of the advent of air transport, the entire production structure and all the induced to it linked (shipping, shipowners, etc.) faced a drastic reduction in demand that reached values close to zero. the progressive exit of scene of the ship from the world of passenger transport forced a radical rethinking that led to the end of the 70s, reflecting precisely on the specific opportunities that the ship could offer compared to the other means of transport, to identify a road through which exit from the structural crisis in which the field was poured.
Thus prevailed the concept of the floating hotel which had as first consequence an overturn of the fundamental principles on which the white ships of the old generation had been conceived. this intuition, supported by intense promotional campaigns, convinced the people to climb on the ships, so that already in 1980 the crociristi in America were a million and a half; Ten years later they had become four million and at the end of 1996 almost six million people were expected to spend two or more days at sea on a cruise ship.

the success of the holidays-cruise has involved the reorganization of the procedures of design and realization of the ships that for the shipbuilding has translated into an opportunity and, at the same time, a challenge.
an opportunity, as the resumption of the demand for cruise ships was born in the middle of a long phase of recession that had hit the section.
a challenge, since reinterpreting the product in the light of technological evolution made necessary on the one hand, recovering a “know-how” largely dispersed, on the other, completely renewing the processes of development and realization of the product.
the prevalence of technological, aesthetic and qualitative factors on those strictly economic, meant that, at least at the beginning, almost all orders of cruise ships were commissioned to shipbuilders of the European area. in this context, the Italian shipbuilding industry, although seriously affected by the crisis of the 60s and 70s, managed to cut out a leading role in the field of cruise ships.
as we have seen the cruise ships, which today offend Venetian, have changed considerably compared to those of the 1930s.
on the design and construction plan the evolution from pure means of transport to floating residential center, has required numerous variations from traditional concepts.
The transatlantic gloriosis of the 1930s were designed according to the speed that was above 25 knots. This involved the installation of engines with high powers, long and narrow hulls to maintain speed even with rough sea and, non-high and concentrated superstructures in the central area of the ship to ensure maximum stability. the current cruise ships instead have relatively small speed and are characterized by wide hulls that form one with the superstructures (the concept of box that I expressed in previous posts). the profile of the latter, called “skyline”, tends to become the characteristic element on the aesthetic plane.
 
this is what “you see” but in reality the differences are more “intime” and concern the service that they themselves have to perform. a modern cruise ship is not only a means of transport but also, above all, a real residential center that must offer countless attractions for passengers of every age.
characteristics of modern cruise ships are: the large number of cabins equipped with external balconies, large glazed surfaces, large public spaces, the large central hall that occupies vertically multiple bridges and which represents the heart of the onboard life.
offering hospitality to 1,000, 2,000, 3,000 people in floating hotels of over 10 floors means preparing a logistic system of exceptional complexity.
- 3,000 passengers and 1,000 crews consume 16,000 meals every day or more than 2 tons of meat, 800 kilos of poultry and as many fish. More than 20,000 pieces between sandwiches, croissants, pasta, etc., 700 liters of milk, 6,000 eggs, 600 kilos of ice cream, 12,000 drinks per day, 650 bottles of wine and champagne, 3,000 cans of beer and almost 6,000 cans of soft drinks.
- to cope with all these needs the ship must have refrigerators and kitchens of enormous capacity, of plants able to dispose daily, in an absolutely ecological way, almost 10 tons of waste, dissalators able to produce 750.000 liters of drinking water, washing machines able to operate on a continuous cycle, air conditioning systems able to maintain constant temperature and humidity in every external condition, etc.; it is also necessary to preview complex circuits of handling for the public board.
- on board, in addition to restaurants, there are numerous public areas: fully equipped cinemas and discos, gyms, fitness and beauty centers, saunas, shops and boutiques - real shopping centers, library, theater.
- the public finally has satellite communication systems that allow to receive television programs, make phone calls, send faxes worldwide.

to transport these “terrestrial” technologies to the marine environment, it was due
aim at what is best available on the market. so to improve comfort, it has been used composite materials, light and soundproofing. technical solutions such as diesel-electric propulsion have been developed to reduce vibration and noise from the engine. cruise ships today are equipped with diesel engines coupled with generators that feed both electric engines of propulsion, and other onboard services. to give an idea of the powers at stake just say that the plant of a ship from 3,000 passengers is able to generate 40 megawatts, enough to feed a city of more than 20,000 inhabitants.
to make it more understandable, I will mention for example some data derived from the experiences matured by the fincantieri which, in order to face the countless technical problems related to the design of the ships from cruise of new generation, had to redefine its relations with the suppliers at the same time managing to cope with the problems related to hydrodynamics, structures, etc.,. thanks to the great experience gained.
for those who had “limited” (if so can be said) to build ships, enter into a different system perspective and the relative technologies, for example, to the hotel system, to the entertainment system, to the conditioning, to the use of innovative materials, etc. was a remarkable step. the fincantieri has had to invent a new phase called "co-design" in which the systems of edge are developed jointly to the supply companies. and if to entrust to the suppliers the design phase and realized has allowed to contain the costs, on the other has made it much more complicated to coordinate and manage the assembly phase. the yard had to assume the role of coordinator succeeding in integrating the activities of the suppliers with that of the company. under the economic aspect, if you consider that a cruise ship costs between 400 and 800 million euros, about six times the cost of a large cargo ship, you must take into account that 75% and beyond is represented by supplies (for a conventional ship you stop to 60%). Here too, there has been great industrialization. if you think that once the cabins were set up by hand with artisanal care, today the same are “modularized” and are shipped practically already finished. this was the result of the improvement of the production phase that allowed a reduction of the construction time from the 19 months of the classical coast to the 16 months of the romantic coast; 23 months for the completion of the statendam, a ship of 55.000 tsl against the 25 months used for the sm princess, a unit of 76,500 tsl.
not within the merit of the financial problems because I would say only cabled but it is clear that the company had to learn how to manage financial issues of particular complexity linked from one side to the high unit value of a cruise ship, from the other to the duration of the construction period.

all this has given rise to a world-wide business, which has had a phase of growth and strong evolution on the level of markets and strategies. This is an activity in which the naval and shipowning component operates in close connection with a wider sector that we could call “free time industry”.
