GMC Seafloor Mining Tool Manufacturing Update
GMC Inc. and partner Protea Sp. z.o.o. are in the final stages of manufacturing the heavy equipment to support the deployment and retrieval of the world’s first deepwater mining riser. The equipment includes a Riser Handling Tool, Gimbal Table, Moon Pool Make Break Tool, and Spider Table with integral Make Break Tool. The system will be used to handle riser joints and perform the makeup and breakout of the 12 and 13-inch main riser mechanical connectors. The GMC-supplied, concentrically-threaded pin and box coupling will be used to connect the main riser sections and transfer mining slurry from the seabed to the surface.
