New Tech Simulates Methane Hydrate Recovery

raising shallow methane hydrate to the surface is the gas lifting method, in which air and other gases are blown into the lifting pipe, making use of the naturally-occurring upward flow generated as the gases mix with the seawater inside the pipe in order to lift the methane hydrate. As no underwater machinery is required, this method reduces the risk of stoppages in production due to mechanical breakdowns in comparison with the pumped lifting method, in which pumps are installed underwater in order to lift the methane hydrate to the surface.The newly developed technology from MES-HD and Fukuoka University

Current solutions as drilled piles or monopiles are quite expensive because they require seabed geology and bathymetry analysis, complicated design, additional machinery for installation and frequent maintenance due to corrosion, fatigue cracks and the grout.   Gravity-based foundations can be eventually considered as the better solution since they don’t penetrate the seabed. However, the overturning moments need to be carefully considered and if the

Further entombment of the seafloor will occur when they discharge tailings into the water column. Not to mention other possible impacts that include light and noise pollution from machinery, and major changes to the geochemistry of the sediment, food webs and carbon sequestration pathways. The cumulative impacts of these operations aren’t yet understood but will likely be long-standing and ocean-wide,” said Dr. Diva Amon, a deep-sea biologist and expert in deep-sea mining

Delivery of the new systems will be end of this year.   While the existing basin will remain, the old hydraulic machinery will be replaced with the new wave generators. The new system is a multi-directional wave generator, with moveable flaps operated by AC servo drives. Installation will be carried out by a local contractor. They will work closely with the team at Rexroth and one of Bosch Rexroth‘s specialists

The C.S. Sovereign, along with her crew of cable engineers and specialist cable equipment and machinery, was contracted for the repair and rapidly mobilized.   Using remotely operated underwater vehicles (ROV) deployed from the back deck of the C.S. Sovereign, the vessel and technical team onboard surveyed the cable on the sea bed, located the fault and recovered the cable ends before successfully
