Milan, Italy -- In mid-2008, pipe-coating expert Bredero Shaw, a subsidiary of ShawCor Ltd, was awarded a contract to produce 40 kilometres of coated insulated pipeline for an installation 120-km off the coast of Sabah in the South China Seas. This deepwater project used special coating equipment supplied by Milan-based Impianti OMS SpA.
To satisfy the needs of Sabah Shell Petroleum's Gumusut-Kakap Deepwater Project, 18-inch (457-mm) diameter pipes were protected with Fusion Bonded Epoxy (FBE) and Bredero Shaw's ThermoFlo D glass syntactic polyurethane insulation coating. This combination is designed for water depths up to 1200 metres, said a 17 March statement from OMS.
This large-scale project is being handled through Bredero Shaw's facility in Kuantan, Malaysia which, with over 600 000 sq.m of plant and pipe storage area, is claimed to be the largest pipe-coating facility in the world.
To complete the coating process for the Gumusut-Kakap pipeline, a special-purpose Impact 300S metering unit was supplied by OMS Group, and installed at the Kuantan facility.
The machine has a maximum output of 300 kg/min and features a special twin-pump arrangement to enable syntactic formulations containing either polymer or glass microspheres to be processed without risk of damage to the delicate spheres. "This is absolutely essential to ensure the required insulation and buoyancy properties of the finished pipe are maintained," said OMS.
To ensure precision of the moulding process throughout the lengthy pouring cycle, the machine is fitted with mass-flow meters and closed-loop control of output and ratio to guarantee accurate control over mix quality.
