We can administer complete asset management of our customers’ hydraulic, control and instrumentation equipment whether topside or subsea, including stock, repair, recertification, overhaul and obsolescence management. We also offer strategic support that overarches everything we do; consultancy services to help our customers achieve optimum solutions, design expertise to generate innovative solutions to the most acute development challenges, and 3D CAD systems to underpin the design and development process.

3sun Group’s preventative maintenance and on-call support services complement the company’s international installation activities. We offer our customers impartial, compromise-free advice based on a single principle: devising and delivering the best solutions for them. The options which the Group offers reflect the unique requirements and priorities of each customer.

The Group is equipped with the knowledge and experience from performing design and service work for many of the major oil companies, varying from replacement of complete subsea systems through valve refurbishment and replacement to fault finding to component level and component replacement. Before implementation we use start-of-the-art simulation software and cost-saving onshore diagnostics to perform dry-runs and testing on all modifications.

We pride ourselves in providing a high level of aftercare to our customers. This includes remote assistance, fault diagnosis and rectification of control system equipment.
