Abstract: An undersea anchor that includes a frame that is fixed to the seafloor by one or more pile anchors, for example grouted pile anchors. The frame is configured to permit it to function with one or more seabed drills to allow the pile anchor(s) to be installed at an angle relative to horizontal so the pile anchors can take horizontal and vertical loads.

Abstract: An apparatus for burying cables and pipes in soil includes a support structure adapted for movement across a surface of the soil. A water jetting machine is provided for producing a source of pressurized water. At least two jetting arms are in fluid communication with the source of pressurized water. The jetting arms have vertical adjustment structure for varying at least the vertical position of each jetting arm relative to the support structure so as to adjust for varying soil conditions. A method for burying cables and pipes in soil is also disclosed.

Abstract: A steerable plow configured for underwater towing along a sea bed. The plow includes a plow body and a soil cutting member attached to the body. The soil cutting member is configured for forming a trench in the sea bed in a forward direction of travel of the plow. A tow member is attached to the body for attaching the plow to a tow cable. The tow member defines an effective tow point which is forward of the cutting member. A steering device is provided for creating a steering moment capable of varying the direction of travel. The steering device is positioned rearwardly relative to said tow member.
