Accommodation platforms and semi-submersibles

We provide integrated water and waste management systems, as well as corrosion protection systems, for offshore accommodation platforms and semi-submersibles. The capacities of our solutions range from a few dozen crew to thousands.

Our NORSOK-approved toilet and wastewater treatment systems – including large-scale membrane bioreactors and sludge driers – are found aboard three state-of-the-art semi-submersible accommodation vessels, known as floatels, operated by Floatel International.

Corrosion protection systems

Our Cathelco corrosion protection systems, based on impressed current cathodic protection (ICCP) technology, are supplied for semi-submersibles operating around the world in locations ranging from the South Atlantic and the Gulf of Mexico to the North Sea and the Arctic waters off Russia.

This breadth of experience enables our engineers to design systems that provide optimal protection against corrosion throughout the life of the structure. Our expertise lies in positioning the anodes to achieve the most effective pattern of current “spread”, and avoiding areas of “shadowing”. In some instances this requires a combination of ICCP and sacrificial anodes.

Semi-submersibles and jack-up rigs generally experience long periods between drydocking. Our Cathelco anodes and reference electrodes are designed to last up to 15 years – and because they are diver changeable they can easily be replaced if required within this timeframe.
