Converting the former 228-metre drill ship into our first polymetallic nodule production vessel

All systems go on board Hidden Gem  as we intensify efforts to covert the former 228-metre drill ship into our first polymetallic nodule production vessel.

Installation of launch and recovery system (LARS)

Out of dry dock and dressed in Allseas colours, Hidden Gem  is now undergoing key modifications in Rotterdam. Works include installation of the vessel’s launch and recovery (LARS) system. Our engineers designed the system to safely deploy and control the 12-metre nodule collector vehicle as it moves across the seabed 5 kilometres below the surface.

Deep-water expertise to support renewable technologies

Allseas has made a name for itself in the offshore energy industry by developing systems and equipment for operation at record depths in challenging conditions. To meet the market’s ever changing needs, we constantly push the boundaries of what is possible.

Drawing on our deep-water expertise and innovative capability, we have designed a LARS for efficient, high performance operation in the world’s deepest and remotest environment. Fitted with a mix of winches and compensators, and housing the control umbilical, the system plays a critical role during offshore operations.

Lying on the deep-ocean floor, polymetallic nodules are rich in critical metals required for energy storage and renewables technologies. Deep-sea nodule collection represents a new frontier and a new exciting chapter in Allseas’ history.
