Description

Transport ship

Technical Field

The utility model relates to the technical field of ship shipping, in particular to a transport ship.

Background

A liquefied gas carrier is a liquid cargo ship that specially carries liquefied gas, and can be classified into a liquefied natural gas carrier (LNG carrier) and a liquefied petroleum gas carrier (LPG carrier). The liquefied natural gas carrier has complex equipment, high technical requirement and larger oil carrier with the same volume and loading tonnage, so the cost is much higher. Liquefied natural gas ships are generally equipped with a gas reliquefaction device and can also transport liquefied petroleum gas.

At present, medium-sized (6-10 million cubic meters) liquefied gas transport ships on the market generally adopt the form of four liquid cargo holds, correspondingly need four sets of liquid cargo containment and treatment systems, have high construction and construction costs, and are not beneficial to later-stage operation and maintenance.

cushion blocks are arranged among the first cargo compartment, the second cargo compartment and the third cargo compartment.

In an alternative embodiment, the total length of the first, second and third cargo holds in the linear array is from 2/3 to 4/5 of the length of the hull.

In an alternative embodiment, the first, second and third cargo holds are provided with a protective covering on the outside.

In an alternative embodiment, the protective layer comprises a protective barrier and/or an insulating layer.

In an alternative embodiment, the first cargo tank, the second cargo tank, and the third cargo tank are liquefied gas cargo tanks.

In an alternative embodiment, the first, second and third cargo holds are each provided with an independent cargo transport system.

The conveying system comprises a liquid inlet cargo pump and a liquid outlet cargo pump.

In an alternative embodiment, the first, second and third cargo tanks are of equal volume.

In an alternative embodiment, the first cargo tank is disposed proximate the aft portion of the hull, the third cargo tank is disposed proximate the fore portion of the hull, and the second cargo tank is disposed between the first and third cargo tanks;

the first cargo hold and the second cargo hold are cuboid square boxes, and one end, close to the head of the ship body, of the third cargo hold is matched with the shape of the ship body to adjust the contractility.

The utility model has the beneficial effects that:

the utility model provides a transport ship, comprising: a first cargo hold, a second cargo hold, a third cargo hold and a ship body; the ship body is of a box-type structure; the first cargo hold, the second cargo hold and the third cargo hold are arranged in the ship body and are arranged at intervals with the ship body; the contracted first cargo hold, the second cargo hold and the third cargo hold are linearly arranged along the length of the hull.

Compared with the existing transport ship with four cargo holds, the transport ship provided by the utility model has the advantages that the cargo is only required to be processed aiming at the three cargo holds, the operation and the control are simpler, and the cost of the required matched equipment for cargo inlet and outlet is lower; in addition, in the case of the same transport amount, the larger the number of cargo holds, the smaller the transport amount of the individual cargo holds, the more material for the cargo holds is required per unit cargo, the higher the manufacturing cost is, and the larger the number of cargo holds, the larger the sum of the surface areas of all the cargo holds, and the higher the safety protection cost for each cargo hold is. Considering that the larger the volume of a single cargo hold is, the lower the mechanical strength of the cargo hold is, the utility model provides a transport ship with three cargo holds, which effectively reduces the production and maintenance costs while ensuring the mechanical strength.
