JDR deploys subsea umbilical contract

JDR has deployed subsea production umbilicals and power cables for the China National Offshore Oil Corporation’s (CNOOC) Liuhua 4-1 field subsea tieback project. JDR designed and manufactured over 42km of ESP power cable, each incorporating nine power cores, delivered in three 14km lengths. The order also included a 14km main production control umbilical and a bridging manifold control umbilical. These umbilicals are operating in the South China Sea, at depths from 260m to 300m. Paul Gahm, JDR VP sales and marketing, said: “CNOOC has utilised the full range of JDR’s capabilities in subsea umbilical design and manufacture to deliver against their objectives on this major project.” He added: “We designed CNOOC’s umbilicals to maximise reliability, minimise project cost and provide the

We loaded out the project, via transpooling, straight onto a heavy lift vessel via the deepwater port alongside our Hartlepool plant.” Each ESP power cable includes three 3-phase power circuits, capable of serving three identical ESPs in this eight well field.

For example we produced the ESP power cables on our vertical lay-up machine (VLM) in Hartlepool. “This enables us to provide ultra-long length electric power cores, which significantly reduces the number of core splices required. “And the design approach we have taken will support future field expansion, with the ability to serve up
