OneSubsea, a Cameron and Schlumberger company, has delivered the world's first subsea multiphase compressor to Statoil for the Gullfaks South field in the North Sea. The compressor enables boosting of unprocessed wet gas production fluids, while eliminating the need for an upstream separation facility or an anti-surge system, making it what the company says is the industry's only true wet gas compressor. It is a contra-rotating machine specifically designed for pressure boosting of unprocessed wellstream, and is expected to increase the recovery rate for the Gullfaks South Brent reservoir by 22 MMboe.

Jee secures phase two of tidal energy development contract

Jee Ltd. has been awarded phase two of a contract with Scottish Enterprise to undertake the demonstration of its U-tube system in Scottish tidal waters.

Jee's protection system, the U-tube, features a pipe fixed to a J-tube which is secured to the turbine foundations at each end of the pipe. The cable is then pulled vertically into one of the J-tubes and through the pipe using a pre-installed messenger and winch line. Once the cable is pulled in, connections are made to the turbine nacelles using wet-mate connections. The U-tube system provides the marine contractor with full control of the cable installation, which can be stopped and reversed if necessary, offering a high level of flexibility.

In September 2014, Jee secured a phase one contract with Scottish Enterprise, which involved a study for the marine energy industry in Scotland. Aquatera Ltd. is responsible for installation.

FES to supply bend stiffener connectors for deepwater Egina project

Saipem has awarded FES International a $2 million contract to supply bend stiffener connectors to Egina project offshore Nigeria, Total's third deepwater offshore development in Nigeria. The Egina project consists of five dynamic umbilicals and the bend stiffener connectors will connect them to the FPSO vessel. FES International has started work on the contract, which will be delivered by May 17, 2015. The field is scheduled to start production by the end of 2017.

McDermott, Petrofac form subsea construction alliance

McDermott has formed a five-year alliance with Petrofac to pursue deepwater subsea, umbilical, riser, and flowline (SURF) projects. The two companies plan to offer a wide range of engineering, procurement, construction, and installation (EPCI) subsea services for deep and ultra-deepwater projects (above $200 million in value) across the US and Mexican sectors of the Gulf of Mexico, Brazil, the North Sea, Mediterranean, and West Africa.

The alliance will combine McDermott's SURF fleet, its new derrick lay vessel DLV 2000 and subsea fabrication capability with Petrofac's new deepwater JSD 6000 installation vessel, currently under construction.

JSD 6000 is designed for ultra-deepwater pipelay, subsea lowering and above surface construction work, through its combined j-lay, s-lay, and ultra-heavy lift capabilities.
