Simrad has been selected as supplier for the complete hydroacoustic instruments suite and all trawl monitoring systems for the NB399 Cattleya, a 62 meter combi fishing vessel scheduled for manufacture during summer 2006, by Karstensens Shipyard in Skagen Denmark. The equipment package is similar in scope to that chosen in March 2006 for the new Isafold super-trawler, also being built by Karstensens.
Cattleya will be equipped only with Simrad Catch control systems. A wireless ‘PI’ catch control system is integrated with the cable based Simrad trawl sonar system. All sensors used on the wireless PI system can be received on the new Simrad FS70 trawl sonar system, giving the skipper full flexibility with all trawl sensors. Due to the integrated set-up, Cattleya only requires one set of sensors for both trawl system and all sensor data can be shown on both the PI control unit and the trawl sonar monitor, providing added redundancy.
The sophisticated FS70 trawl sonar is the result of extensive R&D, to enable even better performance and trouble free operation under all conditions. It features easy to operate ‘sonar like’ software with simultaneous echo sounder function the first of its kind on the market. The transducer on the sonar head is mounted in an oil filled housing, which makes water ingress to the unit impossible and its light weight makes it easy to handle on the deck. The extremely robust housing ensures it can handle the tough environments it will be used in.
There are real cost-savings when integrating a PI system with the FS70, compared to buying Simrad trawl sonar and a non Simrad catch control system together, says Thor Bærhaugen, Simrad. New sensors are constantly developed for these systems and Cattleya will benefit from this in the future.
Cattleya will utilise a new SP93 low frequency sonar, with true multifrequency and third generation beam stabilisation. The SP93 sonar is renowned for its outstanding performance in the high end fishing fleet and will ensure quality and quantity of catch. New software increases the range and provides a completely clutter free picture in addition to the new vertical feature which enables a tilt able 180° vertical view.
Simrad will also supply an ES60 echo sounder with 38 kHz transmitter and transducers. The ES60 is the most flexible sounder in the fishing fleet and provides connection for up to 4 frequencies at the same time and an option for split beam, showing fish size on the screen. With the ES60 as the main sounder Cattleya is able to add new frequencies when needed.
