n: a vessel used to bury a pipeline beneath the seafloor. The barge moves forward by means of anchors. A jet sled is lowered over the pipeline;as the barge pulls it over the pipe, high-pressure jets of water remove soil from beneath the pipe, allowing the pipe to fall into the jetted-out trench.

n: in pipeline construction offshore, a pipe-straddling device fitted with nozzles on either side that is lowered by a bury barge. As water is pumped at high pressure through the nozzles, spoil from beneath the pipe is removed and pumped to one side of the trench. The line then sags naturally into position in the trench.
