Technical advances and changes in the oil, gas and wind industry have resulted in a larger number of offshore installations and therefore also a larger demand for means to commute personnel and to transport goods. Offshore installations and offshore supply vessels require an extensive amount of seawater, which is directly used for cooling processes, to get drinking water and to feed water for steam boilers and other sensitive machines. Depending on the location, the seawater often contains large amounts of salt and calcium carbonate, which can be damaging the pipes and technical machines. Many installations therefore make use of a water softener, yet this still results in many issues with lime scale, biofouling and corrosion.
The Merus water treatment is particularly valuable for the offshore industry, as it protects the hydrophore for the domestic water system, the calorifier feed pipe and the hot water circulation pipe against all sorts of problems related to lime scale, rust and bacteria. In addition to removing these problematic substances, the Merus ring leaves the pipes even cleaner than before, increases the life span of all water-related machines and offers an alternative to the expensive maintenance services.
Multiple platforms of Wintershall have been equipped with the Merus rings. These two pictures concern the Wintershall L8 platform, where the Merus rings have been installed around three seawater lines and the seawater intake to prevent marine growth.
The Transocean Spitsbergen is a semi-submersible drilling facility which has been equipped with the Merus water technology. On this semi-submersible, the main seawater lines were equipped with Merus rings. The main objective was to diminish marine growth at pipelines.
