Wesmar Introduces New Catch Sensors

Wesmar_egg.jpg

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. Numbers 1-4 are compatible with other trawl systems. The catch sensors measure the fill rate of the trawl indicating when the code end is full so the catch can be hauled in at the appropriate time. Catch sensors eliminate the problems caused by overfilling the trawl and improve catch efficiency and quality.   Known throughout the world for its innovative and advanced fishing sonar, WESMAR is no stranger to the needs of fishermen and has worked for several years to perfect a system that reliably measures the fill rate of the trawl and alerts the wheelhouse when the net is full, saving them thousands of dollars in potentially lost catch and/or damaged nets. Wesmar released several features that set their catch sensors apart from other eggs.   They transmit at the highest power on the market. No signal delay. Once triggered the catch sensors send five signals, 5 seconds apart, alerting the wheelhouse instantly


Construction of Marine Science Vessels Up

By Larry Pearson Marine science is making great strides forward due in large measure to several new vessels that have delivered recently and others under construction Headlining this news is the Oscar Dyson, the first of four vessels loaded with scientific gear that the National Oceanic and Atmospheric Administration (NOAA) is having built at VT Halter Marine, Pascagoula, Miss.

Rapp Hydema has been supplying deck machinery to research vessels since 1977, but this global market recently became especially significant for the group. In 2002, in what would be a watershed project, Rapp Hydema was chosen to outfit the NOAA Fishery Survey Vessel (FSV) Oscar Dyson class of vessels. The first four ships in the class were being constructed at VT Halter Marine Shipyard. “That NOAA research vessel contract provided us with excellent exposure

Spills of Nonfloating Oils: Risk and Response

In the USCG Authorization Act of 1996, the USCG was directed to assess the risk of spills for oils that may sink or be negatively buoyant, to examine and evaluate existing cleanup technologies, and to identify and appraise technological and financial barriers that could impede a prompt response to such spills. The USCG requested the National Research Council (NRC) perform these tasks. In response to this request, the NRC established the Committee on the Marine Transportation of Heavy Oils.
