Brief description:

The ship is divided into 13 main watertight transverse sections, (so 12 main watertight bulkheads) each one divided into several compartments by longitudinal (+ one transversal at the stern under the waterline) watertight or fireproof bulkheads. Every watertight bulkheads are fireproof too. The main watertight deck is the M one. All the longitudinal watertight bulkheads, the strong watertight deck, the double bottom and the hull participate to the constitution of the main constraint's structure of the ship located among the seven bottom decks (J deck and lower ones). Above M deck, the transversal watertight bulkheads are prolonged by fireproof ones running to the highs of the ship with fireproof sliding doors too.

The double bottom extends on the 3 lower decks, so 1 m - 3.28 ft above the waterline. The width of the hull combined with the height of the external side allow to preserve the watertightness of the ship as far as an rolling's angle of 25° (in extreme conditions due to extreme dynamic motion of the sea, in the case of the integrity of the ship is preserved, so if there's no dip of course).

The 11 main fire fighting collectors, feeding all the extinguish network (sprinklers, fire fighting pipes and gates...) with salt water, are continuously maintained under pressure by the 9 main watertight pumps located under the waterline and by several smaller other ones located among the decks above.

The 10 external fire fighting collectors (5 each side) can be fed in water from external sources too (from the quay or from another supply ship) in the case of insufficient flow due to electrical problems or other damages or during a dry docking.

On every deck, 10 auxiliary fire-stores, adjacent to the main water collectors/gates, are fitted with various fire fighting equipment (pipes, extinguishers, stretchers, fire suits,  gas masks, survival's equipment...) These auxiliary stores are completed by 6 other larger security dressing rooms and 3 security stores dispatched in the ship at strategic places.

Every power and electrical device's groups are separated by watertight and fireproof bulkheads, so each compartment is autonomous and has greater probability to be functional while other ones can suffer serious damages, in accordance with the last SOLAS rules.

The latest security's equipments are installed to detect and improve the fight against fire and water's damages. All the rooms with motors or electrical devices have a CO2 extinguishing system to avoid water and improve the efficiency in these particular cases. The fight and damages can be detected, managed and coordinated (air-conditioner's gates, electric power, water spraying, pumps for flooding, closure of watertight and fireproof gates, emptying pumps, evacuation...) independently from the 2 security's centers, one located on O Deck and the other on B Deck, in the bridge. Fire, flooding, etc, can be detected from the numerous digital network datas surveillance and control system terminals dispatched through the ship, which allow crew to regularly check all security's parameters / detection during patrols.

Miscellaneous & other functioning:

- Modularity / blocs system construction. Cabins and rooms are located and designed to reduce construction's times, to preserve the structure and solidity of the ship and to simplify the various pipes / wires networks.

- Steel for bottom as far as floor of G deck, aluminium's allow above.

- Very divided and reinforced structure within the bottom decks to improve security, survival capability and to allow a large range of itineraries. Service speed is determined for that too (Trans-Atlantic, light-ice seas, World cruises)

- Deliberated choice of a large width to greatly improve stability and to procure larger available spaces for diversified and extended areas, even if the ship is not "Panamax". However, the hull, by its dimensions, still keeps commonly used and acceptable hydrodynamic characteristics. Besides that, since the Canal returned to Panama possession in 1997, possibilities are seriously studied to enlarge the locks (350X50meters) in future, especially for very lucrative container ships traffic.

- Food & spares embarkation: From M or N decks, depending on port's facilities. Large hull's opening and sorting's areas for trolleys or trucks and direct access towards food's stores & cold rooms on N deck. Large elevators for food (in case of M deck's loading) or spares to access to various storage areas the deck below.

- Food & dishes transit: Direct access of food from stores / cold rooms to kitchen on M deck by elevators. Prepared or cooked food dispatched to various butleries of various restaurants by several elevators / dumbwaiters. Kitchen, dispatching areas, butleries and food's preparation areas designed to avoid dishes, cooked food or washed food to meet unprepared food, wastes and dirty crockery. Wastes evacuated towards treatment unit by separated elevators after meals service.

- Luggage embarkation & sorting: From M deck, 2 elevators towards sorting luggage's area on N deck and every decks.

Remark:  At the present stage of the designing, it's impossible for me to gather enough reliable informations regarding the weight of every element - metallic structure - depending of the resistance of various part of the ship too -, mechanic and electric devices, various equipment, furniture, decoration, etc... A whole and very extended documentation, calculation's power and lot of time would be necessary - but out of reach for me - to obtain an accurate and reliable synthesis. That's why, for example, even if many parameters (such capacities, superficies, hull coefficients and datas...) above have been of course truly determined or calculated in relation with the plans, I can't determine precisely the vertical position of the center of gravity "G". So, the calculation of the stability parameters (GM in relation with the center of flotation of the hull, or the influence of the flooding of such or such compartment...) , although essential in the development of such a project, isn't displayed here since it would be an approximation only or the result of several hypothesis covering several estimations among them the real one for this ship, without knowing precisely which one is the more accurate and so the closest to the reality. More, professional naval architects are by far more able than me to do this job and this is not the purpose neither the pretentiousness of my work which is concentrated on the general layout and style of the ship. However, since I wanted this work to be feasible and credible, I entered an enormous quantity of parameters and constraints such as the hull's shape, an adequate distribution of the weights, ballasts, location of various elements or volume of engines in relation with the necessary power, to speak about architectural field only. That's why, even if I'm sometimes unfortunately forced to remain in an empiric / not state of the art approach, I have no doubt the stability parameters of this ship are in a good average value, especially by considering its large width (even if penalizing for the hull's output - however a deliberated choice) and by using an extrapolation with the datas of existing ships.
