Whittaker Engineering Ltd- have developed a unique water backed weld procedure, we believe that we are currently the only company in the world offering this procedure with full Lloyds Class approval. The procedure uses high powered induction heating coils to maintain the welding pre-heat temperature whilst welding water backed plate, mitigating the heat loss through the hull into the cold North Sea. The resultant weld is ductile, low in hardness, excellent impact properties and has a heat effected zone free of martensite.
This procedure has been highly effective on four separate occasions saving our clients a potential dry-docking, in all occasions our client did not have to stop production.
Whittaker has applied this repair method on semi-submersibles and an FPSO.
