The order for cranes to be used on Nautilus Minerals’ production support vessel (PSV) has been awarded to MacGregor, headquartered in Kristiansand, Norway. It is the third major long lead time equipment package to be awarded by the shipyard, Fujian Mawei Shipbuilding Limited.
The order for cranes consists of two knuckle boom units. The first crane is a large 200-tonne SWL crane with 2500 metre water depth capability and equipped with active heave compensation. The second crane is a smaller 100-tonne SWL auxiliary crane to support back deck and ship to ship operations.
Knuckle boom cranes are preferred for offshore use due to their inherently compact dimensions and ability to reduce the effect of ship motions on suspended loads. The large active heave compensated crane will also be capable of deploying and recovering various items of mining equipment directly to and from the seafloor.
Both cranes will be used to load stores, spares and support the maintenance of shipboard SPTs and other items of production equipment during mining operations.
The cranes are due to be completed and delivered to the shipyard for integration by quarter one of 2017.
Nautilus’ CEO Mike Johnston said: “We are very pleased to have such a world-class supplier providing key equipment for use on our PSV. The cranes are an essential component in ensuring operations can be performed safely across all of our large working deck areas.
“The 2500 metre depth rated heave compensated main crane also provides critical lifting support to our subsea operations at the mine-site. We look forward to reporting on the progress of this equipment as we move closer to production in 2018.”
