Afren (LON:AFR) and its partner Oriental Energy Resources conducted the naming and sail-away ceremony for the Virini Prem Floating Storage Offloading vessel (FSO) at the Yulian shipyard in China.

The Virini Prem FSO (formerly Prem Prachi) will be the crude oil storage and export facility for the Ebok field development located offshore southeast Nigeria. The indigenous company Century Energy Services will be the ship crewing agent in Nigeria.

The Virini Prem, a 267-meter and 174,917-ton vessel which has been refurbished at the Yulian shipyard in China, will store and offload for export, stabilized crude oil that will be produced and processed at a dedicated Mobile Offshore Production Unit (MOPU) at the field location. The FSO has a storage capacity of 1.2 million barrels and will accommodate regular crude oil offtake by tankers up to VLCC size. 

Refurbishment work included steel replacement in certain sections of the hull, existing equipment on the vessel (such as export pumps), installation of a helideck and accommodation modules for up to 50 crew. The fiscal metering package has successfully undergone acceptance testing to DPR approved standards. The successful execution of refurbishment work on the FSO is a major milestone for the Ebok project.

In readiness for the arrival of the FSO, all 12 mooring lines have also been successfully pre-installed at the field location. Additionally, fabrication of all flowlines required to transfer produced crude oil from the MOPU to the FSO has been completed, which will be stowed on the FSO for transport to the field. Development drilling activities remain on schedule at the field, where six horizontal production wells and one water injection well are being drilled and completed in advance of the FSO and MOPU arrival.

Ebok is one of the largest independent developments undertaken in Nigeria to date, and Oriental and Afren believe that the field is part of a prolific hydrocarbon area that has substantial further potential. Afren extended its asset base in 2009 and 2010 to include further partnerships with Oriental in the Okwok and OML 115 assets adjacent to Ebok. Appraisal well drilling is shortly due to commence at Okwok and will be followed by an exploration well on OML 115.

"The Virini Prem FSO Naming and Sail Away Ceremony is a major milestone for the Ebok development, and an important step towards first oil, at what will be a core production hub for the broader Ebok/Okwok/OML 115 area,” Osman Shahenshah, Chief Executive of Afren, commented.
