Cathelco have won orders to supply equipment for two projects which are being undertaken by Keppel yards in Singapore.
The first is to provide marine growth protection systems (MGPS) for a KFELS semi-submersible drilling tender (Project B374).
The Cathelco MGPS system will eliminate blockages in sea water pipework caused by the growth of barnacles and mussels. A total of four seachests will be protected, each with flow rates of 1,160 m3/hr. This involves fitting two copper anodes and one aluminium anode in each of the seachests which are wired to a control panel.
In operation, the copper anodes produce ions which create an environment where barnacles and mussel larvae do not settle or breed, but are carried through the system to discharge. At the same time, the aluminium anode produces ions which create an anti-corrosive coating on the internal surfaces of pipes.
