China’s Wison claims largest Type B LNG tank

China’s Wison Offshore & Marine completed what it calls the world’s largest self-supporting Prismatic Shape IMO Type B Tank (“SPB”) for storing liquefied natural gas (LNG).

With storage capacity of 47,000 m3, this tank stands as the largest single product ever designed and built using SPB technology since its debut in the 1980s, the company said. The tank will be used in a Floating Liquefied Natural Gas (FLNG) facility under construction.

By leveraging various automatic welding techniques, the construction period of the first tank has been compressed by over 50%, the company said.
