Marathon Oil’s latest offshore gas platform, has set sail from its Dutch fabrication yard to destination field located offshore Equatorial Guinea.

The Alba B3 platform, has been fabricated by, Dutch firm, Heerema.  The company has also been tasked with installation, hookup and commissioning of the platform.

The Alba B3 has been designed as a gas compression platform to enhance the capacity of the existing Alba gas and condensate field, located approximately 20 miles (32 km) off the coast of Equatorial Guinea capital, Malabo.

The platform will sit on a 91 meter (300ft) high steel jacket base. The topside itself, 40 x 40 meters, weighs a total 5,800 tonnes. The B3 fabrication has also included a bridge that will link the platform back to the existing Alba B2.

The platform is due to arrive in the Alba field early 2016, where it will be met by Heerema’s own heavy lift crane barge, the Thialf, that will lift both jacket and topside into place.

Speaking on the news, Heerema Fabrication Group CEO, Koos-Jan van Brouwershaven, said: “We are proud that after being involved in the FEED study to also have executed the EPCI scope for Alba B3. Working on such a complex scope, executed at many different locations worldwide requires intensive communication and project management skills”.
