MAY 2015 THE SKIPPER Trawl Tech 29

Marport Deep Sea Technology

Marport have launched the new M3 Receiver in December 2014. This new receiver is designed as a highly sophisticated multi-function acoustic receiver. It uses leading edge digital signal processing that has combined with the smartest software available to make possible multi-channel operation without any compromise between transmission range and signal detection. The M3 is designed to meet the needs of smaller vessels, accommodating a series of full-function channels to allow simultaneous use of standard sensors, net sounders – including narrow band – and high resolution net sounders, all of which can be configured to suit the most advanced net monitoring system. This is the new M3 receiver is adapted to the needs of smaller vessel this fleet. without losing any of the characteristics and performance of the bigger M4 receiver. “This new receiver has also allowed us to offer smaller vessels a sophisticated catch monitoring receiver to the small pelagic trawlers and white fish vessels,” explains Marport France . This allows the vessel to see a number of parameters on one screen from one sensor. These

can include Door Distance, Pitch and Roll and Depth from one sensor. Fishing Skippers can now see in real time exactly what the doors are doing at anytime during the tow and makes the system one of the best in the market.

Marport’s sensors have been designed from the start to work seamlessly with other systems. We don’t see why you should have to fit an entire system when a single sensor or receiver needs replacing, all Marport sensors and bridge equipment work seamlessly with other manufacturers’ sensors and wheelhouse displays. All sensors are compatible with Scanmar, Simrad and Wesmar sensors.

Marport Door Monitoring for White Fish Vessels A Marport Door System will save fuel and reduces damage to trawl gear. Immediately you will know if your doors are standing up straight or falling in, if you have picked up a stone or if you have damaged your gear. It is proven that with a proper functioning door system your trawl efficiency will go up by 15 to 20%. Marport Trawl sensors are designed to play a role as a contributing factor

in maximising efficiency, targeting fishing at the most productive spots and keeping fishing time to the minimum needed for your quota while keeping your fuel bills to a minimum.

Marport have introduced the new Dual Clump. This system shows if

the clump is ahead, behind or inline with the port and starboard doors. People with standard Marport clumps can upgrade to the Dual Clump option.For further details on any of the above please contact Chris Joyce at Barry Electronics for further details Tel 074 97312

Trawl Tec 2000

HBG service was founded in January 2004 by Heimir B. Gislason and Sólrún Hansdóttir and their objective from the beginning was to deliver service to the fishing industry

Trawl Tec 2000 can be used in variable Fishing, trawling and Line fishing, from small boats up to big vessels. Trawl Tec 2000 for trawlers measures the tension and the length of the wires. It save both time and equipment.

Trawl Tec Line measures the speed of the line when shooting and hauling in plus the tension of the line when hauling in, which is good for saving engine power and in bad weather to have less tension of the line.

Trawl Tec Line 2000 is equipped with GPS. The system is user friendly and used in several fisheries and it can help to increase catches and lower cost.

Gunnar Jóhannsson captain on Sigurbjörg ST-55 says:“It was a good decision to invest in Trawl Tec. It has saved us a great deal of time after we started to use this equipment because before we often had to pull wires and rope to a shore. Both wires and ropes were often damaged in that process. Fuel consumption has also decreased by 10-15% due to less engine power usage when towing and hauling. Decreased reparation for trawl and other engine equipment has also been noticeable. In my experience this equipment pays for itself in matter of a relatively short time. After my experience I can only highly recommend Trawl Tec.”

“Trawl Tec 2000 Line makes our work at sea much easier. We have more overview of the line, both when setting the line as well as controlling the tension when hauling in, especially in rough weather. I highly recommend this equipment.” Jón Bessi Árnason captain on NÚPUR BA 69

Fishing is one industry that is in a constant state of change - new technology brings changes almost on a daily basis - and top skippers seek to find the best gear, the best way of catching and landing fish in top quality, and vitally, the most economical means of operating a fishing venture. Maximising catching ability is of course totally reliant on good fishing gear and the latest in electronic fishing aids.

It is with this in mind that The Skipper this month looks at Trawl Technology - and examines the latest and most up-to-date fish finding equipment and trawl gear available to owners/skippers of today’s vessels.

Embracing evolution in trawl design

Enhancing their historic reputation as leading international net manufacturers, Swan Net Gundry (SNG) are investing in the pursuit in ongoing research and development into pelagic and whitefish trawls.The past twelve months in particular has seen exceptional results for

SNG with innovative designs such as the new Helix self-spreading hydrodynamic technology and ‘Pelix’.

SNG’s mackerel and scad Helix self-spreading trawls proved highly successful in 2014 and 2015, when performance reports were glowing from the skippers of Antares, Zephyr,

Antarctic 11, Veronica, Paula, and Krossfjord … to name but a few.

Tapping into technology

For skippers, the advent of Helix and its beneficial properties has brought great improvement to the processes of shooting, towing and hauling.

Most important among these is that Helix ropes, over-braided with colour-coded protective skins, give trawls wider openings -- improving performance and, in heavy weather, help keep the net in shape. An added benefit is that Helix ropes reduce trawl drag, thereby improving fuel consumption.

Testament to claims that the stiff Helix ropes make trawls easier to shoot and haul, and that Helix twine is less inclined to twist, is evidenced in that SNG customers using this technology in blue whiting fisheries reported zero ‘foul ups’ of gears. SNG have advanced this technology for pelagic pair trawlers using similar constructed twine built with heavier construction to withstand the rugged

handling of gear. Titled ‘PELIX’, this displays the same benefits of Helix but with the added abrasion-resistant qualities necessary.This year has also seen advancements in SNG’s blue whiting brailer design with impressive bags of 850 tonnes recorded on Antares, Zephyr and Brendelen --without a damaged mesh reference.

Looking ahead

SNG has invested in model-testing software using DynamiT program to further improve the firm’s proven designs which, including the blue whiting brailer and Helix self-spreading trawls will be part of SNG’s Flume Tank Workshop on 20th & 21st of May in Hirtshals, Denmark.This presentation will see SNG showcase their forward-thinking strategies with the presentation including underwater cameras to assist in monitoring performance – which will benefit not just the pelagic sector but those using all types of demersal trawls including nephrops, multi rig, and hopper trawls.

Electrical Drive Technology in the Fishing Fleet

Denmark, USA, Russia are amongst the countries that have made a concerted effort to renew their fishing fleets in order to reduce costs and comply with increasingly strict environmental laws, choosing electrical drive technology in a bid to achieve these ends. Electric drive on equipment not only reduces the space required for its installation but is lighter and more efficient giving better winch performance.

The Faroe company, KSS (www.kss.fo), is the Sales and Service partner of Ibercisa in Denmark, Faroe, Greenland, Sweden and within fishing Ireland, Scotland and Shetland.

Ibercisa, a company devoted since its inception to the design and manufacture of deckmachinery is very aware of how greatly the demand for electrically driven machinery hasbecome over the last few years. Ibercisa will supply winches for the Danish highly modern pelagic vessels, Ruth HG 264 and Beinur HG 62, being built at Karstensen Shipyard due in 2016.

The vessels, 88m and 78m length have been equipped with 3 main trawl winches, two “purse seiners” and 4 net drums. The order for each vessel comprises a total of 27 and 16 electric winches driven by frequency variators and with AFE energy return.In the U.S.A. Fishermen Finest based in Seattle will build a new trawler ST-116XL design for delivery in 2016. It is the first vessel to be built according to new construction rules in the states and will give impulse to the incorporation of technology which is more environmentally friendly and with which the North American company has decided to prioritize fuel consumption efficiency by installing electric deck machinery.

The Ibercisa order includes, the control systems, 2 electric trawl winches, 2 gilson electric winches, 6 electric sweepline winches, 42 net sounder winches, 2 cod-end winches, 3 net drums, 1 auxiliary anchor winch, 1 mooring winch and two auxiliary anchor winches. This electric drive technology is being used in the remodelling of the Russian fishing fleet, traditional clients of Ibercisa who have recently signed contracts for the supply of deck machinery for the “Kapitan

Oleynichuck”, the “Vladivostok” and the “Borodino” which will be remodelled to include electrically driven machinery. Ibercisa will supply electric trawl winches with motors of 400 kW at 660 rpm, and a capacity for 4,000m of 32 mm diam. These winches have a line pull of 49,5 tons at 44 m/min on the first layer.

The “Kapitan Oleynichuck” will have auxiliary cod-end winches driven by

55 kW engines at 1.500 rpm, with double drums for 100m of 20mm diam wire and 40m of 30mm diam rope and a nominal line pull of 5,1 tons at 56 m/min on the first layer. For this vessel the company will also supply electric auxiliary Gilson winches with 160 kW motors at 1,500 r.p.m. with a capacity of 125 m of 44mm diam., rope.

New twine construction at KT Nets

As they celebrate the twelfth anniversary of the foundation of the company in May, KT Nets is looking forward to an exciting and productive show at Skipper Expo in Aberdeen.

Taking time off from his busy schedule, managing director Danny Gallagher, said: “One of the most interesting projects we are involved in at present is based on the development of a new type of twine in conjunction with Van Belen.“It’s a new construction using

Van Belen materials and we are still working on it. But the initial feedback is very positive”, he siad. “If anyone wants to know more about this, we will be happy to discuss it with them in Aberdeen on our stand, No. 48”.

Looking back, Danny says that, along with local work, KT Nets have had an exceptional year’s work with the Norwegian vessels during the recent blue whiting season.

“We were working all hours of the day and the night; one morning we

didn’t get away until 4am. That’s the commitment and dedication of the team here to getting our customers back fishing”, says Danny.

One of the more recent orders completed by KT Nets is a new blue whiting trawl, with 2,048 metres circumference, for Eamon McHugh’s “Antarctic”.

Said Danny: “We used the new construction of twine in that net and Eamon says he is very happy with it. It was very successful in the trials.”At their location at Donegal Road,

Killybegs, KT Nets is the most visible of the netmaking companies in Killybegs. They have a 300 metre runway at their disposal and new shed with 1,000 square metres of workspace.

KT Nets has ten full-time employees along with part-time staff and are looking forward to meeting new and existing customers in Aberdeen. Said Danny: “We have a strong foothold in Ireland and we are gaining ground all the time in Scotland and Shetland. Here’s to the next twelve years.”

New ‘Exocet’ trawl doors from Morgère ideally suited for Irish and UK fisheries

Despite only being launched at the start of 2015, Morgère’s new Exocet trawl door has received much interest from skippers in Europe and Canada and looks set to become the ‘trawl door of choice’ for many fishermen in the future.

Exocet offers excellent stability due to its special design where nearly 60% of the weight of the door is focused at the base, with the top half much lighter. These innovative design features means the angle of attack of the doors can be reduced without comprising upon spread in the trawl opening, resulting in savings in fuel consumption.

During trials on a working fishing boat, it was found that with the same angle of attack as the vessel’s previous doors, the Exocet achieved 10% more

spread of the trawl opening. In order to keep the same spread as previously experienced by the vessel, the angle of attack of the doors needed to be reduced considerably to around 25°, significantly reducing the drag forces experienced by the vessel. The skipper was especially impressed by the stability of the doors and by the fact that they are easy to shoot.

The tough construction also means that the doors are very durable and last much longer than standard steel doors, bringing further cost benefits.

According to Michel Dagorn of Morgère, the Exocet door is incredibly versatile and can be used in a variety of different trawl configurations.

“These doors are well suited for fishing conditions found off Ireland and the UK,” he says. “We wanted to develop a trawl door that reduces fuel

consumption and is more stable and easy to shoot. We believe we have achieved this with the new Exocet and we are delighted with

the results.”Morgère will be exhibiting at Skipper Expo Int. Aberdeen 2015 on 29 and 30 May.

Electrical winches in Fishing vessels

Electrical winches have been used on board fishing trawlers for decades. Still there is some misconception that it is more difficult to use electrical winches and that they require more generator power compared to hydraulic winches.

Naust Marine in Iceland is a world leading manufacturer of control equipment for electrical winches in fishing vessels, with over 35 years of experience in making Automatic Towing winch systems. Since 1980, Naust Marine has been delivering systems for some of the biggest fishing trawlers in three continents in addition to the smaller modern trawlers built for Icelandic owners. Today, more than 100 ATW (Automatic Trawl Winch) systems are in operation on board trawlers all over the world, with its latest delivery for trawlers in Chile, Russia and USA. Electrical winch system from Naust Marine is also on board the Research vessel Cefas Endeavour, owned by the Fishery Institute in the UK.

Some of the great advantages of using the electrical systems versus hydraulics is lower operational cost (fuel cost), due to better efficiency in the electrical systems and possibility of using generated

power during shooting the trawl wire. Other advantages are the lower installation cost and less maintenance cost. All electrical systems from Naust Marine on board vessels, can be monitored over the internet, for possible programming and fault tracing from our technicians in the office.

Due to the increasing demand for various fishing winches for all type of trawlers (bottom trawling and pelagic trawling), Naust Marine has started designing its own brand of winches. The extensive experience of the Naust Marine staff with the fishing industry, is the base for the winch design, as well as the controls.

In Turkey and China alone, five new trawlers are under construction for Icelandic fishing companies. In all of these projects, Naust Marine provides winches and winch controls where all auxiliary winches are designed by Naust Marine, in total of 120 winches in range from 4 kW and up to 130 kW. Towing winches are 210 kW DC, where the regenerated power is set back to the Main Switchboard, during shooting.

Please visit Naust Marine for further information and details at Stand no 46 at the Skipper Commercial Fishing Expo in Aberdeen, May 29th -30th 2015.

FV Ocean Challenge: 11 Years Working Notus and Still Going Strong

Notus does many news stories regarding new installations and new products. However, some of the most gratifying stories come from long term customers. One such vessel is the FV Ocean Challenge of Scotland. Notus recently had a chat with one of the owners, George Runcie, regarding his experience with Notus.

The first system fitted by Notus UK in 2004 was on the Ocean Challenge. They installed one sensor on each door and two on the clump to monitor: the spread on EACH net, the three wire lengths and the middle wire adjustment. George says “we’ve been very pleased with our Notus gear.” He points to the most important feature as the spread

on EACH net as “you need to know what each net is doing.”

The quality of Notus’s equipment is certainly seen on the Ocean Challenge. Over 11 years, they’ve only replaced batteries. All by local agents! Considering the sensors are installed on some of the roughest trawl gear (middle weights/clumps), this is a wonderful testament to the Notus design.

Even when changing vessels 7 years ago, George says “we took the Notus gear with us for the new vessel.” George also provides some details on the fishing operation. The Ocean Challenge targets prawns off Northeast Scotland in 55 to 90 fa. They pay out 3:1 for the wire to depth ratio. Typically, they are achieving 35 fa of spread on each net. They target prawns 9-10 months per year

and a typical trip is 7 days.

Few realized at the time, but that first installation on the Ocean Challenge started a major change in the UK industry. Other vessels quickly seen the value of a wireless monitoring system specifically designed for twin

rig. Today, over 200 systems have been installed in the UK and Ireland. You would be hard pressed to find a twin rig skipper that has not used or seen the technology.
