The contract, valued at approximately $350m (£281.26m) over a five-year period, is for Block B.  

It encompasses a range of technical services for onshore support bases, an FPSO unit and a platform on behalf of GEPetrol, the national oil company of Equatorial Guinea. 

Petrofac said the contract draws on its Asset Solutions business’ core services such as asset integrity, integrity management, maintenance, marine services, operations, project delivery, supply chain services and well engineering.  

It added that this agreement extends its involvement with the asset, following its initial work assisting the transition from Mobil Equatorial Guinea. 

The Zafiro oilfield is located in the 500,000-acre Block B offshore development area, close to Nigeria's international maritime boundary with Equatorial Guinea. 

Existing staff and contractors will maintain their roles to preserve critical skills and familiarity with the operations.  

Petrofac plans to administer the contract from Malabo, with additional support from its technical centre in Aberdeen, UK. 

Petrofac Asset Solutions business chief operating officer Nick Shorten said: “We look forward to developing our relationship with GEPetrol further, collaborating to extend the life of the field to build a legacy of energy independence and sustainable growth for Equatorial Guinea. 

“Africa is a key focus for our Asset Solutions business and we are pleased to build on our operations in Ivory Coast, Ghana and Senegal, and Mauritania with this opportunity in Equatorial Guinea.” 

Petrofac's other recent contract wins include a $200m agreement last month with Turkmenistan's state-owned Turkemengas for the Galkynysh gas field.  

Furthermore, in January, Petrofac was selected by oil and gas giant bp for a three-year operations services contract for the Greater Tortue Ahmeyim (GTA) project. 

The GTA project is a liquefied natural gas development situated on the maritime border between Mauritania and Senegal.  

BP leads the GTA project, in partnership with Societe des Petroles du Senegal, Societe Mauritanienne des Hydrocarbures and Kosmos Energy.
