According to Whittaker, traditional welding specifications used for the design and manufacture of floating production units and oil rigs do not take into account the cooling effects of seawater. The new procedure uses high-powered induction heating coils to maintain a pre-heat temperature while welding water-backed plate, mitigating the heat loss through a ship’s hull into the cold temperature of the sea.
Keeping warm
Whittaker Engineering, an independent engineering, procurement and construction company, has developed a water-backed welding procedure for in-situ vessel modifications and repairs that can considerably reduce costs by preventing dry docking and the resultant loss of production.
