Embodiment 1

[0054] Embodiment 1. In this embodiment, the method for refitting a fuel tank of a container ship according to the present invention specifically includes the following steps:

[0055] Step 1: Dismantle the existing guide rail frame structure 4 in the target cargo hold 1 of the container ship. The target cargo hold 1 refers to the cargo hold in the original container ship where fuel tanks need to be installed.

[0056] Step 2: According to the structural characteristics of the bulkhead of the target cargo hold 1, a double-layer watertight bulkhead structure is respectively arranged at the front end and the rear end of the target cargo hold 1 cabin body, specifically including the following steps:

[0057] Step 2.1: Determine whether there is a double-layer watertight bulkhead at the rear end of the cabin of the target cargo hold 1 (that is, determine whether the double-layer bulkhead structure 2 close to the engine room area of ​​the target cargo hold 1 is a double-layer watert...

Embodiment 2

[0075] Embodiment 2. In this embodiment, the method for refitting a fuel tank of a container ship according to the present invention specifically includes the following steps:

[0076] Step 1: Dismantle the existing guide rail frame structure 4 in the target cargo hold 1 of the container ship.

[0077] Step 2: according to the characteristics of the bulkhead structure of the target cargo hold 1, a double-layer watertight bulkhead structure is respectively arranged at the front end and rear end of the target cargo hold 1 cabin body, and the specific implementation steps and embodiment 1 of setting the double-layer watertight bulkhead structure same.

[0078] Step 3: arrange a plurality of first support bases 5 and a plurality of second support bases 6, and the arrangement positions of the first support bases 5 and the plurality of second support bases 6 are the same as those in the first embodiment.

[0079] In this embodiment, both the first support seat 5 and the second supp...

Abstract

The invention discloses a method for refitting a fuel tank of a container ship, which comprises the following steps: removing the existing guide rail frame structure in the standard cargo tank; Set up a double-layer watertight bulkhead structure respectively; arrange multiple first support seats in the target cargo hold; hoist the B-type fuel tank with the second support seat installed on the top into the target hold; Set the first fireproof insulation structure on top; hoist the fuel gas supply structure module on the upper part of the B-type fuel tank, and connect the piping system and electrical system of the B-type fuel tank with the system equipment in the fuel gas supply structure module. The invention can refit the container ship from traditional heavy oil fuel to LNG fuel on the basis of retaining the original container hull structure to the greatest extent, greatly reduces the emission of carbon dioxide and nitrogen oxides, and meets increasingly stringent environmental protection requirements.

Description

technical field [0001] The invention relates to ship building, in particular to a method for refitting a fuel tank of a container ship. Background technique [0002] Under the current background of stricter environmental protection pressure, LNG fuel is gradually recognized by the maritime community as a clean energy source. The LNG containment system is used for the isolation and heat insulation of low-temperature LNG liquid cargo, and is a necessary and core system for ships to load LNG fuel tanks. LNG containment systems are mainly divided into membrane type and independent type, and the independent type cargo tank is further divided into type A, type B and type C. The B-type tank has the characteristics of tank capacity utilization, flexible layout and good anti-sloshing performance, so the application of the B-type tank has a great market prospect. [0003] Container ships are one of the three main types of ships in the maritime industry. At present, most container sh...
