ABSTRACT

Pipeline protection is often achieved through burial in the seabed sediment. One common way that this is achieved is by ploughing (e.g. Finch et al., 2000). A large (e.g. approximately 20 m long) plough (Fig. 1a) is dragged through the seabed, and the plough forms a ‘V’-shaped trench into which the pipeline is placed before usually being backfilled.
