Heerema Fabrication Group, the Netherlands-based manufacturer of large structures for the oil and gas industry, has informed through social media that the Alba B3 topside and jacket have been installed at the Alba field, offshore Equatorial Guinea. 

The platform sailed away from the Netherlands towards its offshore location in December 2015. The jacket was built at the company’s yard in Vlissingen and the topside was built at the Zwijndrecht yard under a contract awarded by the Houston-based oil and gas company Marathon Oil in April 2013.

The transportation and installation scope of work was conducted by the company’s sister division Heerema Marine Contractors. The company used the Thialf crane vessel for final offshore installation.

The platform was originally scheduled to be installed on the field by end-2015 with start-up expected in mid-2016.

The 5,800-tonne topside was mated with the 91-meter tall jacket weighing 2.600 tonnes some 32 kilometers offshore Malabo, Equatorial Guinea. The topside is 40 meters long and 40 meters wide with the height reaching 35 meters. The 33-meter-long, 4-legged jacket is 33 meters wide and 81 meters high.

The Alba 3 platform will compress gas from the existing Alba B2 platform through a 33-meter-long bridge connection. With this new platform, Marathon is expecting to boost production from the gas and condensate field.
