Project Experience

Dai Hung – Phase 3, Block 05-1(a), Offshore Vietnam

The Phase 3 of the Dai Hung project, located in Block 05-1(a) offshore Vietnam, was completed. Phase 3 involved the delivery of a 3 km dynamic subsea power system, connecting the floating production unit (FPU) to the wellhead platform (WHP-D1). The subsea dynamic power cables, equipped with fibre optics, and accessories were manufactured at JDR's Hartlepool facility. After production, the cables were loaded onto drums with a diameter of 9.2 meters and shipped to the installation site. This project plays a crucial role in the energy infrastructure of the region.

Angola Block 15

JDR produced 13.5 km of specialist Umbilicals for the oil extraction platform at Angola Block 15. This project is part of the ongoing development of the oil extraction sector in Angola, helping to increase oil production in the region.

BEACH ENERGY OTWAY

JDR supplied four subsea production umbilicals, ranging from 400 to 4300 meters in length, for the gas extraction system in the Otway Basin off the coast of Australia. The subsea umbilicals, featuring thermoplastic cables, enabled increased production at the gas facility and provided a new source of gas for Australia's East Coast. The umbilicals were installed through an existing J-tube on the drilling platform, with the second umbilical connecting to the SDU to link the Thylacine North-1 well, located 4 km northwest of the platform. This project supports the growth of the offshore sector in Australia, ensuring the delivery of energy and natural resources.

Petrogas Transportation B.V.

JDR delivered 68.5 km of Subsea Production Umbilicals for a gas production platform located 250 km off the coast of the Netherlands. This project was crucial to the development of offshore infrastructure in the region.

Zuluf AH Crude Increment

JDR delivered two contracts in the Persian Gulf, producing a total of nearly 9 km Subsea Isolation Valve Umbilical’s as part of the Zuluf AH Crude Increment program. This project supports the increase in oil production in the region.

Black Sea Oil & Gas – Midia Gas Development

JDR delivered an 18km, 7½ksi umbilical for the Midia Gas Development in Romania’s Black Sea. The umbilical connected the Doina subsea production system to the Ana platform, helping meet Romania’s gas needs and marking the first offshore development in the region in over 30 years.

Anyala & Madu

The Anyala and Madu fields are located within the OML 83 and 85 leases in the shallow waters of the Niger Delta, approximately 40 km off the coast of Bayelsa State, Nigeria. The fields are estimated to contain a total of 193 million barrels of oil (MMbbl) and 0.637 trillion cubic feet of gas.

As part of the Anyala & Madu project, JDR supplied a total of 23.7 km of umbilicals, including power and control umbilicals that connect the FPSO to the Madu and Anyala fields, as well as the Subsea Isolation Valve (SSIV). The cables and SSIV were manufactured at JDR's facilities in Littleport and Hartlepool, UK. These supplied cables will contribute to optimising gas extraction costs from the Anyala and Madu fields and will be directed to a gas processing hub to meet the local market's needs.

Offshore Platform Project, Azerbaijan

As part of the offshore platform project in Azerbaijan, the facilities in Bydgoszcz and Hartlepool jointly supplied a 33kV fibre optic power cable, 5.5 km in length, along with a Subsea Isolation Valve (SSIV) umbilical for the platform. This project provides the necessary energy infrastructure, supporting production in the region.

ITHACA Energy – Cook Water Injection Project

JDR supplied a 925m thermoplastic production control umbilical for Ithaca Energy’s Cook Water Injection Project in the Central North Sea. This umbilical system connects the Cook Production Manifold to the Water Injection Tree, supporting reservoir pressure.

IWOCS Supply and Service in the Gulf of Mexico

JDR signed a contract for the provision of IWOCS services for a deepwater project in the Gulf of Mexico. The contract, which began in February 2020, included the supply, installation, and maintenance of optical electrical downlines and integrated fibre optic conduits for eight wells, as well as IWOCS umbilicals, terminations, safety systems, and hydraulic power units (HPU). JDR also supplied additional technical specifications required to ensure the project could withstand significant deepwater pressures. IWOCS, winches, OEDL, HPU, flying leads, and other equipment were provided by JDR’s Houston, US office.

Na Kika A7 Well Project

In 2019, JDR supplied an IWOCS rental system for operations in the Gulf of Mexico, specifically for the Na Kika A7 well. Designed to work independently of the drilling riser, this system ensures resistance to strong subsea currents. The innovative design freed up valuable deck space, reduced installation time, and proved effective in challenging marine conditions. The system included a single-wire deployment solution and 15,000 psi control umbilicals, demonstrating JDR’s expertise in providing efficient and reliable subsea solutions for complex offshore projects.
