Case Study: Global Energy Group – Bluewater Haewene Brim FPSO

Location: Inshore, Nigg Dry Dock

Primarily, this was a medium scale project where Sureclean were contracted to undertake inspection and deep tank cleaning of all tanks, NORM compound management, and ERT cover onboard the Haewene Brim FPSO when inshore for a scheduled visit.

Sureclean Scope

Primary scope of work was to provide the necessary manpower and equipment for inspection and cleaning of 140 tanks onboard the FPSO.  Over the course of the project, this scope grew to some additional 40 work fronts, the most significant being ERT cover, NORM management, Chartek and Lagging Removal, industrial 'deep' cleaning and waste management.

The project management team within Sureclean were based onsite, integrated within the client's site team.  This ensured effective communication between both parties and allowed issues to be handled more effectively.
