MODIFYING SEABED CONTOURS
In preparation 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, for example after being re-engaged with a supporting frame from which the weight was dropped. This leaves an elongate indentation at the drop location with a base less inclined than the previous inclination of the slope at that location. 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.
