Abstract: The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.

Abstract: 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.
