Afren and its partner Oriental Energy Resources reported that the Ebok Mobile Offshore Production Unit (MOPU) has left the Gulf Copper Yard in Galveston, Texas, for Nigeria.
The Veer Prem MOPU will be the crude oil production and processing facility at the Ebok field development located offshore southeast Nigeria.
The facility is a former jackup drilling rig that has been successfully converted to a MOPU by removing the drilling package and replacing it with a newly fabricated processing module.
Work undertaken has also included the installation of new accommodation and a helideck. It has been prepared with an initial oil production capacity of 50,000 bopd, water injection capacity of 25,000 bwpd and gas lift/injection capacity of 9/6 mmcfd. Crude oil produced and processed at the MOPU will then be stored on the 1.2 million barrel capacity Floating Storage Offloading vessel (FSO), which will accommodate regular sales offtake by tankers up to VLCC size.
The facility has been designed to allow for on-site expansion and upgrade to also accommodate production from any future additional development phases at the field.
The advantages of using a converted jackup is that the installation will not require a derrick barge, and can therefore be installed whilst development drilling and well testing operations are in progress. Furthermore, opting for the MOPU/FSO development configuration has provided cost savings compared to alternative Floating Production Storage Offloading vessel (FPSO) options that were previously considered.
It is planned that the MOPU and FSO will become a central facility for the broader Ebok/Okwok/OML 115 area, allowing for the economical and rapid tie back of production from any future developments in the surrounding area.
Both the MOPU and FSO are expected to arrive on location during November, with production start up remaining on track by year end.
"The Veer Prem MOPU Sail Away Ceremony marks a successful conclusion of the refurbishment and fabrication of the remaining key piece of production infrastructure required at the Ebok development,” Osman Shahenshah, chief executive of Afren said. “It represents a significant further step towards first oil at the project, and establishing a production hub for the broader Ebok/Okwok/OML 115 area."
