Sembcorp Marine subsidiary SMOP has awarded Dutch firm Framesa contract for the supply of two seawater electrochlorination systems, one wellhead control panel complete with a hydraulic power unit, and three hydraulic power units for topside and subsea valves.
The systems are designated for the high-pressure, high-temperature Culzean gas field, 145km east of Aberdeen, in the UK North Sea.
The development, consisting out of a wellhead platform, central processing platform, and living quarters, will be operated by Maersk.
Culzean will be expected to be capable of providing around 5% of the UK's total gas consumption by 2020/21.
“We are proud that we have received this award from Sembcorp Marine Offshore Platforms and that we are a part of this project,” says Sjoert Bolhuis, Sales Manager at Frames Flow Control & Safeguarding. “This is not the first time we have cooperated with Sembcorp Marine. Together, we’ve already realized several successful projects, such as floating production, storage and offloading (FPSO) vessels P-68 and P-71 and Pioneiro de Libra.
Frames has already worked with Maersk on projects including Halfdan BD, Tyra South East, and Al Shaheen Block 5.
The seawater electrochlorination systems that Frames has been awarded for will play an effective role in optimizing the flow assurance of seawater that is being used for multiple purposes on both platforms (e.g. cooling water, firewater). The restriction of seawater flows, corrosion, and the reduction in the overall lifespan of the process equipment can all be minimized by the effective design of a seawater electrochlorination system.
The seawater electrochlorination systems also provide the most effective and environmentally safe method for the prevention of biofouling that would negatively affect the seawater systems within an offshore facility. Every electrochlorination system that Frames delivers includes Evoqua’s Chloropac self-cleaning concentric tubular cells that do not require acid washing or other electrode cleaning methods.
