Introduction
Grand Ocean is a leader in Submarine Cables, used by oil and gas operators around the world for the power link for Floating platform, FPSO, and fixed platform. It covers great distances and water deeps and are designed to operate in dynamic submarine environments for many years.

Subsea Power Cable design typically contains three power core phases. Each phase comprises a large copper conductor. Our designs are specially engineered and manufactured to suit the dynamics and the challenges of each individual customer’s submarine application. We offer a range of subsea power cable solutions that can include fiber optic communications between fixed and floating offshore installations.

Grand Ocean offers a full range of custom made umbilical cables providing the power, signal, and mechanical link for submarine equipment, such as ROV, trencher, renewable power generation equipment etc. Our designs offer the most compact electrical and fiber optic assembly diameter, highly flexibility and can be strengthened with either high strength synthetic fibers or multi-wire armoring layers to support the weight of the associated ROV, package, handling forces, vessel motion.

Advantages Of Grand Ocean Submarine Cable
1 Flexibility in materials selection and configuration of manufacturing processes e.g. a range of polymer options
2 Three-phase AC systems with a voltage range of 1kV to 35kV.
3 Both ‘wet’ and ‘dry’ design types using either EPR, TR-XLPE or XLPE three layer insulation systems
4 A range of armoring options, from roundness to tetragonum, from single to multi-layer
5 Coilable and non-coilable designs
6 Termination pre-installation that can obvious reduce the offshore installing time and enhance the efficiency.
7 Assembly, qualification and testing in-house to avoid risk of commissioning delays
8 ORIENT offers full dynamic analysis, fatigue analysis and seabed stability analysis to prove the suitability of our SDC designs.

Product Description
Grand Ocean design offer excellent structure stability and EMC performance; thermoplastic elastomer water-tight sheath provide highly mechanical strength and abrasive resistance; highly durability and reliability; Torque balanced steel wire armor design.
DC voltage source based converter (VSC) high-voltage direct current transmission has been developed a new type of HVDC technology in recent years. The system included the DC Submarine cable, converter transformers and related accessories.
