(West Africa) - JDR Cable Systems has been awarded two separate contracts from FMC for the supply of workover control umbilicals.

FMC Technologies Inc. has placed an order for two 7,500-ft long electro-hydraulic umblicals for the Agbami project offshore Nigeria.

The 10,000 psi rated umbilicals will be used for initial installation of the subsea trees and for workover operations throughout the field life.

The umbilicals are designed to operate in water depths ranging from 4,200 ft to 5,400 ft and contain special high collapse resistant (HCR) hoses capable of withstanding 5,000 psi external pressure.

Final assembly and testing of the umbilicals will take place at JDR's Houston facility.

After manufacturing is complete, JDR will spool and integrate the two umbilicals onto air-driven reel units.

Testing of the reel unit and hydraulic fluid flushing will be carried out prior to final delivery at the Houston site.

A separate purchase order from FMC Kongsberg Subsea AS was received by JDR Cable Systems to design, manufacture, and test two electro-hydraulic umbilicals with air-powered reeler and sheaves for the deepwater Moho Bilondo project offshore Congo.

The 1,170-m long main WOCS umbilical with a complete spare will work in water depth to 900 m, and each umbilical incorporates two each 1" x 5000 psi JDR-designed and -qualified HCR hoses for circulation of low-density well fluids and chemicals.

Prior to manufacture, a sample length of umbilical will undergo API 17E qualification tests including tensile, bend stiffness, crush, and fatigue tests, with the latter performed on JDR's new purpose-built fatigue cycle test rig.

The rig is designed to simulate the umbilical's path from deployment reeler, over sheaves, and into the marine riser.
