Abstract

The invention discloses a method for installing and locating a pump well of a Mark III type LNG fuel tank, which comprises the following steps: installing the pump well in the opening of the pump well; Assemble the pump well positioning device; install the pump well positioning device on the pump well; insert a positioning ruler vertically into each positioning groove of the pump well positioning device respectively, and the bottom edge of the positioning ruler is against the bottom plate of the ship; Move the pump well positioning device until each positioning ruler coincides with the pump well installation line, at this time, the pump well is installed in place. The invention can quickly adjust and locate the installation position of the pump well by using the pump well positioning device, thereby improving the installation precision of the pump well and ensuring the construction quality of the ship.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a Mark III type LNG fuel tank pump well installation and positioning method. Background technique [0002] With the development of science and technology and the improvement of the quality of life, people pay more and more attention to the protection of the environment. SO produced by the combustion of old fuels such as oil and coal mines X and NO X It has been criticized by people all the time, but after the complete combustion of liquefied natural gas, the only products are water and carbon dioxide. It is a clean, efficient and cheap alternative green fuel, so it is more and more favored by people. At the same time, the International Maritime Organization (IMO) has gradually increased the standards for ship exhaust emissions. Due to the limitation of fuel, the traditional two-stroke diesel engine is no longer popular. Many ship owners have turned their attention to using...
