Pipeline-Trawl Interaction: Effect of Trawl Clump Weights
Volume 4: Terry Jones Pipeline Technology; Ocean Space Utilization; CFD and VIV Symposium, 2006This paper deals with clump weights, a new type of component in bottom trawl gear that needs to be considered in design and reassessment of pipelines. In recent years it has become popular to use two trawl bags, a so-called twin trawl, to increase the swept area and, thus, the efficiency of the trawler.

Bottom Trawling. One of the most common ways to catch fish is by dragging nets along the seafloor. This causes changes in the plants and animals that live there. When the same areas are trawled frequently, the community on the seafloor can be drastically changed. Long-lived species such as corals and sponges are severely affected.
