MacGregor, part of Cargotec, has received order from Shanghai Zhenhua Heavy Industry Co Ltd (ZPMC).
The contract is for four offshore cranes, including a 400-tonne SWL active heave-compensated crane capable of deploying 3,000m of wire rope.
All four cranes will be fitted to a new 145m dive support vessel (DSV) under construction at the yard for UK-based operator Sealion Shipping.
Delivery of the cranes to the Chinese shipyard is scheduled during third quarter of 2016.
Sealion is an offshore support company that manages and operates offshore support vessels for Toisa.
The DP3 vessel is equipped for worldwide operations in the oil and gas sector and on ultra-deepwater projects. Delivery is planned for early 2017.
