Suction pile cofferdam

A subsea cofferdam comprising:

• a plurality of open frame structures comprising at least a first open frame structure and a second open frame structure;
• each of the first open frame structure and the second open frame structure comprising walls defining an interior, an open bottom end, and a closed top end, one or more fluid conduits extending into the interior, and a fluid port configured to allow removal of fluid through the fluid conduit in an open configuration and maintain a negative pressure within the interior in a closed configuration,
• wherein each of the first open frame structure and the second open frame structure are configured to be driven into a sea floor by allowing fluid to be removed from the interior of each of the first open frame structure and the second open frame structure, via the one or more fluidic conduits, to thereby generate a vacuum that induces a negative pressure within the first open frame structure and the second open frame structure, wherein each fluid port is closed to maintain the negative pressure within the interiors for the first open frame structure and the second open frame structure to generate forces on the closed top end of the open frame structures that pushed the open frame structures in the sea floor when the open frame structures are installed in a sub-sea configuration.
