Accidental Limit State of Submarine Pipeline: Trawl Gears Pull-Over Loads and Effect of Free Span
Submarine pipelines failures lead to oil spills in water and may even lead to explosions with heavy financial and environmental damages. Trawl gear is one of the main factors in the failure of the submarine pipelines. In this paper, sensitivity analysis is performed on influence of height and span length alternations on the response of pipeline against the traction caused by trawling pull-over ...
متن کاملA simplified model for bottom trawl fishing gears
Computational modeling is a valuable complementary tool to assess behavior of bottom trawl fishing gears. A simplified model of the gear that mainly affects to the net is proposed. The model is constrained to steady towing conditions, flat seabed and gear symmetry. Simulations proportionate a number of relevant outcomes like distribution of tensions at the warp, balance of forces at the otterbo...

متن کاملMpas as a Tool for Addressing the Collateral Impacts of Fishing Gears
An often overlooked aspect of fisheries management is the collateral impact of fishingbycatch and habitat damage. Discussions concerning the role of marine protected areas (MPAs) and fisheries management have focused on recovering depleted fish stocks through adult immigration or larval dispersal, but relatively little discussion has focused on the use of closed areas to address collateral impa...
