Modifying seabed contours
A method for installing subsea infrastructure such as a pipeline, an adverse seabed contour is modified by dropping an elongate weight onto a seabed slope to penetrate the seabed. The weight is then lifted away from the slope leaving an indentation in the seabed. The indentation can be extended into a groove by repeatedly dropping the weight onto the seabed in longitudinal alignment to form a series of conjoined or overlapping indentations. The weight may be dropped at a sloped transition or shoulder between a depression in the seabed, such as an iceberg plough mark, and the general level of the seabed surrounding the depression. An apparatus for modifying a seabed contour comprising a supporting frame from which a wedge-shaped weight is dropped. A quick release mechanism couples the weight to the frame.
