(US) - JDR Cable Systems will design, manufacture and test three Electro-Hydraulic (EH) umbilicals with air powered reelers and sheaves for Expro International Group Plc.

The umbilicals will be used to control Expro's Electro-Hydraulic Landing String Control System for the Tahiti and Blind Faith projects in the GoM.

The 3 x 8,000-ft long umbilicals are required to work in 7,000 ft of water at temperatures of up to 210 ºF, while being exposed to well completion fluids. External pressure requirements are 6,000 psi, and maximum umbilical operating pressure is 15,000 psi. The umbilical is designed with high collapse resistant hoses to handle the high temperatures and pressures.

Prior to umbilical manufacture, a sample length of umbilicals 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 the deployment reeler over the sheave and into the landing string.

With both umbilical and reeler managed by the same JDR team, special requirements can be identified quickly, implemented and managed through completion of the package.

"We are delighted to work with both the Expro Group and Chevron on umbilical systems that must be built to a very demanding specification," said Patrick Phelan, managing director of JDR's Oil & Gas Division.
