The Rosyth dockyard Goliath crane has been made by ZPMC in China. It is not a standard product, and as such it could have been made by any suitable fabrication yard or shipyard in UK. Extensive and expensive supervision by the UK contractor has been necessary to ensure compliance with the specification and welding standards.
ZPMC are specialists in container cranes. Their other products are general steel fabrication. They have recently fabricated the new seismically upgraded Oakland Bay Bridge for San Francisco and a Shiploader Wharf for Port Hedland, Australia.
Pity we have exported our bread and butter work to China.
