A ship

Abstract

A roll-on and roll-off ship comprising a front part (50), a rear part (60) and a central part (70) is disclosed. The ship is arranged with holds adapted to accommodate containers etc. in the front part and in the rear parts and roll on / roll off cargo in the central part of the ship. The central part extends from the tank top to a level above the weather deck. A ramp is provided in the aft part of the ship, and the roll on / roll off cargo transits from the ramp to the third cargo hold section via a passageway arranged in the aft part of the ship. The passageway may be arranged as a tunnel, which may be adapted to support cargo stowed above the passageway.

Description

technical field [0001] The present invention relates to a vessel that provides high cargo capacity and flexibility through a unique design of the combination of a cargo hold section for containers and a cargo hold section accommodating vehicles. [0002] According to one aspect, the present invention relates to a ship comprising a hull, a weather deck, a forward part, a rear part, a central part, and first, second and third cargo hold parts. [0003] The forward portion of the vessel includes the first cargo hold portion for accommodating cargo in the form of containers and is defined non-exclusively by the hull and the weather deck, wherein the weather deck being located at a height above the baseline of the vessel and including an access hatch or opening to provide access to the first cargo hold portion; [0004] The rear portion of the vessel includes the second cargo hold portion for receiving cargo in the form of containers, defined not exclusively by the hull and the we...

AI Technical Summary

Problems solved by technology

This concept is widely recognized and used, but a common disadvantage of this concept is that in the case of a ship loaded with an uneven composition of gravity, such as when only one type of cargo is transported, the ship operates with unsuitable stability

[0016] In loading situations where the center of gravity of the cargo is too low, the ship will operate with too high a stability, causing the ship to quickly roll from side to side, causing discomfort to the crew and increased cargo damage, etc.

[0017] However, as far as so-called ro-ro ships are concerned, the prior art does not propose a solution for optimum flexibility and capacity

In particular, the conventional construction of RO-RO ships, due to the aforementioned stability-related deficiencies, places limits on the amount of additional cargo that can be carried, and on the conditions under which such cargo can be carried
