2H Offshore to Deliver Flexible Riser System for TEN Development Offshore Ghana

2H Offshore, an Acteon company, has been appointed by Tullow Oil as lead riser engineering consultancy for the delivery of the flexible riser system for its Tweneboa, Enyenra and Ntomme (TEN) field development, offshore Ghana.

The TEN development is located in the Deepwater Tano block, approximately 30km to the west of the Jubilee field and lies in water depths ranging between 1,000m and 1,800m.

The development will consist of oil and gas production wells, water injection wells and gas injection wells. Production will be gathered through subsea manifolds and flexible risers to a Floating Production Storage and Offloading vessel (FPSO). 2H will ensure the riser engineering design complies with ISO 13628-2 and provide recommendations on riser optimisation, installation and overall assurance that the risers meet the project Basis of Design (BOD) and specification.

“We are delighted to have the opportunity to work with Tullow Oil in leading an integrated riser engineering team to deliver the flexible riser system for the TEN development,” said 2H Director, Hanh Ha. “Our in-depth knowledge and experience with flexible risers will enable us to develop and optimise the system to meet the project’s combined challenges of deep water, complex subsea bathometry and aggressive delivery schedule.”
