发明名称 PIPELINE BALLAST AND METHOD OF USE
摘要 A pipeline ballast has at least two sacks adapted to straddle a pipeline. Permeable sacks filled with inert high density aggregate such as barite uses less dry weight of aggregate to restrain buoyancy. Preferably a top sac k and two pairs of side sacks connected to either side of the top sack, which when cinched, conform to the pipeline. Preferably each side sack is a pair of sac ks which are flexibly hinged for more efficient loading onto the pipeline and f or better conforming to the pipeline when cinched. Preferably a one piece cinching strap has two loops spaced thereon hook and loop type fasteners at the loose ends for securing together once cinched. The cinching strap is wrapped about the pipeline ballast and the lifting loops are positioned low on either side of the pipeline and lifted tangentially away from each other before the loose ends of the strap are secured to each other.
