Abstract: The present techniques are directed to systems and a method for reducing trenching around piles. An exemplary method includes attaching a mooring line to one end of a padeye extender bar that is coupled by another end to a padeye on the pile. The pile is installed in a sediment layer. The padeye extender bar is deployed to hold an attachment point for the mooring line above the sedimenlt layer.

Abstract: Systems and methods for reducing scouring around piles are described. The system includes a pile and an enclosure. The pile has a maximum cross-sectional dimension, Dp. The enclosure is circumferentially disposed around the pile, the enclosure having a first end proximate a surface of a seabed; a second end distal the surface of the seabed; and a maximum cross-sectional dimension, De, wherein De is at least 1.25*Dp.

Abstract: An apparatus including: a tubular suction pile; an indenter housing that surrounds the tubular suction pile, wherein the indenter housing is configured to: (a) be sunk into a seabed in response to a negative pressure created from water being removed from the tubular suction pile, and the indenter housing is configured to create a trench in the seabed; and comprise a water jetting device, within the indenter housing, that includes a first valve, a nozzle, and a channel that connects the first valve to the nozzle; and/or (b) impart a longitudinal vibration to the indenter housing and the indenter housing is configured to be sunk into a seabed in response to longitudinal vibration, and the indenter housing is configured to create a trench in the seabed.

Abstract: A system and method for obtaining soil samples is described. A coring system includes a suction carrier, a pump and a corer. The suction carrier comprises a body defining a cavity and a top portion having an aperture. The pump is positioned adjacent to the aperture and constructed and arranged to deliver fluid from the cavity. The corer is constructed and arranged to releasably engage with the suction carrier.
