China-based provider of clean energy services Wison New Energies (WNE) has hoisted the first self-supporting prismatic shape IMO type-B (SPB) tank for Eni’s Congo liquefied natural gas (LNG) project into hull cargo hold space at the Nantong yard.

The SPB tank, designed and constructed by WNE and intended for the Marine XII Offshore floating LNG (FLNG) project (Congo FLNG), is said to be the world’s largest SPB tank . The construction started in February 2023, with the upper and lower bodies of the tank closed in July, around the time when the topside fabrication began . The installation of the tank, which Wison described as “the core equipment” of Eni’s Congo LNG project , was finalized on March 2, 2024.
