Description

INFIL COVER ASSEMBLY OF FLNG VESSEL < RTI ID = 0.0 >

The present invention relates to an infill cover assembly of a FLNG ship.

In general, the upper structure of an offshore structure is subjected to hull motion due to waves, algae, and wind, and is always subject to inertial force.

And marine structures such as Floating Liquid Natural Gas Plant (FLNG) vessels are equipped with several modules for producing / purifying LNG on the hull. For the movement of various equipment and workers between these modules, FLNG ships are equipped with an infill cover which connects the modules.

However, in the case of conventional FLNG ships, there is no separate treatment facility for receiving sewage / rainwater at the connection portion between the modules, so that when sewage / rainwater is generated, sewage / rainwater can not be properly treated on the infill cover do.

Therefore, an infill cover technology is required which can move between various modules of equipment and can easily handle sewage / rainwater at a connection portion between modules.
