CHESTERFIELD, UK -- Cathelco has supplied a hull corrosion protection system for the Armada TGT 1 FPSO.
The 332-m (1,089-ft) long vessel, converted by Keppel Shipyard in Singapore for Bumi Armada Berhad, will work on the Te Giac Trang oilfield offshore southern Vietnam for the Hoang Long Joint Operating Co. It is designed to produce up to 55,000 b/d of oil and store 620,000 bbl.
Cathelco has provided 800 amp fore and aft impressed current cathodic protection (ICCP) systems, to protect the hull against corrosion over its 20-year design life.
Both systems comprise 400 amp thyristor control panels wired to pairs of anodes and reference electrodes mounted on the surface of the hull.
In operation, the reference electrodes measure the electrical “potential” at the hull seawater interface and relay a reading to the control panel, which raises or lowers the output to the anodes to ensure that optimum corrosion protection is maintained.
The Armada TGT 1 has been installed with linear loop anodes which are diver changeable, allowing operations to be performed at sea.
Cathelco has also supplied an ICCP system for the Amore, an FSO which is being converted by Keppel for Bumi Armada Berhad.
