Trawling

Hansen Develops Efficient Factory Trawler

50 m factory trawler.

50m Factory Trawler sets the standard in efficiency and fish processing capacity.   The Danish Naval Design and Marine Consultancy Knud E. Hansen A/S has developed a highly efficient 50 meter factory trawler with a focus on operating efficiency and maximised catch processing facilities. The design delivers excellent fuel economy, reduced environmental impact, and the flexibility to be operated as a single or pair trawler. Fishery Fishing is well known to be an environmentally sustainable method of food production. Greenhouse gas emissions are far lower than the equivalent land-based meat production.   Trawling Even though trawling has been regarded as destructive and high oil consuming, it is a fact that pelagic trawling together with purse seine is the most sustainable way of catching fish measured by energy consumption and emission of greenhouse gasses per unit catch. Through the use of new technology pelagic trawls can also operate close to the bottom catching “ground-fish” without damaging the sea bed. In addition, pelagic trawling has a low rate of unwanted by-catch compared to other fishing methods. Trawling does therefore have a future as a sustainable way of producing food.   Size of trawler   Standards of safety, working- and living conditions together with the desire to allow reasonable space for processing catch on board have led to an optimal ship length of at least 50 metres


Wesmar Introduces New Catch Sensors

Wesmar, a U.S. manufacturer of sonar equipment, has introduced its new line of trawl sonar catch sensors. ‘They are the fastest and most powerful on the market,” said Dennis Soderberg, WESMAR’s Vice President of the Electronics Division.   The Model CS20 WESMAR catch sensors work with the highly popular WESMAR TCS780 and TCS380 trawl sonar systems. Up to six catch sensors can be used on the cod end of a WESMAR system

It looks like a typical Gulf of Mexico double-rigged shrimp trawler. However at 110 by 28-ft she will be bigger than most shrimpers. Like her sister, the Poncho, delivered in 2009, the new vessel is also built with robust framing and extra power. Like the Poncho, the as yet unnamed vessel, will be trawling for scrap metal, old tires and any other scrap is at the site of a decommissioned oil rig.   The work, mandated by U.S


Rapp Electric Winches for New O’Hara Vessel

F/V Araho

Rapp Hydema landed a contract for theoutfitting of the new trawler F/V Araho, a 185-ft. freezer-trawler being built for O’Hara Corporation at Eastern Shipbuilding in Pensacola, Fla. The owners had originally planned to retrofit the F/V Harvester Enterprise but instead opted for an outright newbuild.  The new trawler build has potential to mark the first of several new trawler builds to replace aging hulls throughout the Alaskan trawl fleet.
