Patent number: 11787708Abstract: A disclosed subsea sediment separation and filtration system includes first and second separation devices, a spreader apparatus, and a storage device. The first separation device receives a water/sediment/oil mixture and from a subsea surface and separates the mixture into a first component containing cleaned sediment and a second component containing a water/oil mixture. The spreader apparatus disperses the cleaned sediment of the first component into a subsea environment of the spreader apparatus. The second separation device receives the second component from the first separation device and separates the second component into a cleaned water component and an oil component. The second separation device disperses the cleaned water component into a subsea environment of the second separation device and provides the oil component to the storage device. The first separation device may include a plurality of hydrocyclone devices, and the second separation device may include a high pressure hydrocyclone device.Type: GrantFiled: January 12, 2023Date of Patent: October 17, 2023Assignee: DELTA SUBSEA LLCInventors: Scott Paul Dingman, Perry Loughridge

Publication number: 20230003000Abstract: A cofferdam is disclosed that includes an open frame structure having double walls defining a hollow space within each double wall, with each double wall having an open bottom end and a closed top end. Each of the double walls are configured to act as suction piles allowing liquid to be removed from the space within each double wall to thereby induce negative pressure when the cofferdam is installed in a sub-sea configuration. Each of the double walls may include a plurality of partitions respectively defining a plurality of suction piles, the suction piles fluidically coupled by a manifold that may allow liquid to be removed from the suction pile to thereby drive the cofferdam structure into the subsea surface due to the induced negative pressure. A further embodiment cofferdam structure includes an open frame structure and one or more suction piles attached to the open frame structure.Type: ApplicationFiled: September 13, 2022Publication date: January 5, 2023Inventors: Scott P.
