China’s Wison New Energies has installed all four SPB LNG tanks and two LPG tanks on Eni’s Congo FLNG.
The company, previously known as Wison Offshore & Marine, said in a social media post on Monday that the final lifting of LNG and LPG CCS for the Marine XII Offshore FLNG project (Congo FLNG) had been successfully completed on April 23.
The first SPB (self-supporting prismatic shape IMO type B) LNG tank was on March 2 hoisted into the hull cargo hold space at its Nantong yard.
WNE previously said the SPB tank, designed and constructed by the company, is the world’s largest SPB tank and it is the core equipment of the Eni Congo LNG project.
The entire tank is 45 meters long, 44.9 meters wide, with a main body height of 24 meters and a total height of over 31 meters.
Also, the tank has a volume of 45,000 cubic meters, with a total weight exceeding 1,400 tons.
Two FLNGs
WNE won a contract from Italy’s Eni in December 2022 to build a 380 meters long 2.4 mtpa FLNG and officially started work on the project in January last year.
It will be able to store over 180,000 cubic meters of LNG.
The FLNG will serve Eni’s Congo project which will reach an overall LNG production capacity of 3 million tons per year, or about 4.5 billion cubic meters/year, from 2025.
In February Eni shipped the first LNG cargo from its Tango floating LNG facility moored in Congolese waters and this shipment arrived last month at Snam’s FSRU-based facility in Piombino.
The Italian firm purchased the 144 meters long Tango FLNG from Belgium’s Exmar and chartered the 2002-built steam turbine LNG carrier, Excalibur, to serve as an FSU for the project.
The floating LNG producer, delivered in 2017 by Wison, has a liquefaction capacity of about 1 billion cubic meters per year of gas, or 0.6 mtpa, and a storage capacity of 16,100 cbm.
