Bestream Offshore, one of the companies in OEG Energy Group’s subsea division, has secured a contract by TenneT for the retrofit installation of a corrosion protection system for the SylWin alpha offshore converter station for the offshore grid connection SylWin1 in Germany.The award is for the subsea installation of an Impressed Current Cathodic Protection (ICCP) system to replace the existing faulty ICCP system.The replacement of the existing system includes the decommissioning of outdated cables and debris which cause system interference, alongside a pre-survey which will be conducted using a

Subsea Monopile Corrosion Protection

Corrosion and BlueStream launched ICCP-SAM, touted as sustainable corrosion protection of XX(X)L monopile foundations. ICCP-SAM is designed to remotely install ICCP anodes on monopile foundations of all sizes, anywhere on the foundation and even in the roughest ocean conditions.The ICCP-SAM (Subsea Assembly Method) is compact and can be transported and deployed with minimal resources from the topside of the offshore foundation. It is operated remotely and maneuvers the anode underwater into the designated foundation entry hole. The anode is then secured to the foundation using the same tool.

Imenco Launches Offshore Mooring Chain Corrosion Protection Tech

Imenco Corrosion Technology (ICT), a division of Imenco, has launched what it says is a transformational mooring chain cathodic protection technology, named Pacu.Initially designed for deployment on FPSO mooring chains, the system, Imenco says, is equally applicable to any mooring system such as those on floating wind platforms or offshore aquaculture installationsImenco says that the solution, made up of its Piranha clamp and an integrated bracket-mounted sacrificial anode, slows the rate of corrosion significantly and prolongs the life of mooring systems."Currently, the unpredictable rate of

the North Sea, it is common to assume that structural details located below or in the splash zone are not accessible for inspection and repair.” The splash zone is defined in DNVGL standard, ST-0126.“Inspection of structures in the splash zone and below water focuses in addition on the corrosion protection systems (steel wall thickness, anodes, coating, etc.), marine growth and scour protection.” Yet, OceanTech’s tools do that hazardous work. The iCon robot addresses these and subsea structures as well, starting with risers that could lose buoyancy if fouled by marine life: they

extraordinary. This is the effective alternative to metal facing or very expensive alternative fillers. And because it is part of the Subsea Industries family, it is fully compatible with our coatings.EcolockEcolock is used on stationary offshore units. The main benefit of the coating system is corrosion protection and the possibility to clean it. These units are designed to stay on location for 15, 20 and even up to 30 years. Hull integrity and corrosion protection is a major thing. Class demands an underwater inspection twice every five years to see if the hull is in good shape. So the hull must be
