The Solwara 1 Joint Venture comprising Nautilus Minerals and Eda Kopa (Solwara) Limited 15% has been advised that Factory Acceptance Testing (FAT) on the Subsea Slurry and Lift Pump (SSLP) has commenced at the GE Oil & Gas manufacturing facility in Houston, USA. The SSLP will be used in the seafloor mining project of the JV in the territorial waters of Papua New Guinea.

Nautilus’ CEO Mike Johnston said, “The SSLP is a key element of the Solwara 1 Joint Venture’s seafloor production system, enabling us to transfer the mineralised material as a slurry from the seafloor to the Production Support Vessel (PSV) with no interaction with the overlying water column. We look forward to successfully completing FAT on the SSLP and taking delivery of the pump later this year.”

The SSLP and riser system transfer the mineralised material as slurry from the deep ocean up onto the PSV, where the mineralised solids are removed. The return water is then filtered to 8 microns, and transferred back down to the pump via the auxiliary riser pipes where it is released back into the same environment from which it originally came.

GE Oil and Gas produces positive displacement pumps like the SSLP for the offshore oil and gas industry, where amongst other things, they are used to help limit the environmental impacts of drill cuttings in deep water drilling operations by helping recover the cuttings for eventual storage on land.
