Winches Northern developments
The latest developments from North Sea Winches were displayed at this year’s Seawork Exhibition. Two 185tonne hydraulic winches for well head operations in the Gulf of Mexico are the biggest winches that North Sea Winches has made, to date. The winches are driven by four piston-type
hydraulic motors, through planetary gearboxes onto an open ring gear to achieve the required performance. The drums are designed to hold 230m of 35mm wire or 90m of 88mm rope, which is spooled on with automatic guiding gear.
for LD Travocean, of Marseille, for mooring duties on a cable-laying barge. The winches incorporated remote-controlled clutches and brakes, and were fitted with automatic spooling gear for 1000m of 36mm diameter wire.
Pumps Hydraulic pump
protection Magnom has recently released the PumpMate, which is designed to be a cost-eff ective pump protection solution off ering fi ltration of fi ne ferrous materials to sub-micron levels. PumpMate is specifically designed to protect
hydraulic pumps on the suction side, the PumpMate’s patented design off ers a generation leap in technol- ogy for the protection of critical hydraulic and lubrication pumps, with virtually no pressure drop or restriction fl ow. With a high contaminant holding capacity the
PumpMate is a true ‘fit and forget’ solution, as the company describes it. PumpMate provides whole system protection from ferrous contami- nants, reducing wear and tear within critical valves and components, whilst enhancing system and performance and increasing fluid and additive life. Reduced downtime and enhanced system perform-
ance increase fl uid life time and simple installation and that equals to zero risk of cavitation rugged construction. T e Magnom PumpMate Magnetic Filter (Magnetic
A 185tonne hydraulic winch for well head operations in the Gulf of Mexico.
T e company is continuing to forge ahead with new
designs for the tug market, such as with a 50tonne waterfall type anchor handling and towing winch, with remote-controlled self-calibrating dog clutches. T is winch has just successfully completed sea trials on Al Barkut, the latest 35m tug built at Hepworth Shipyard for Holyhead Towing Co. North Sea Winches also has future plans for
60tonne and 80tonne anchor handling tug supply winches with complete wheelhouse control. All designs are created in-house which means that North Sea Winches can cater for most hydraulic winch requirements from 500kg pull upwards. Another recent successfully completed project was the supply of eight model GM-1100 hydraulic winches

Suction Strainer) is specifi cally designed to protect hydraulic pumps on the suction side, inside the tank (reservoir). The patented design filters the suction side of
pumps; unlike a standard suction strainer, that is not a fi lter as such. Magnom provides the performance of a one micron absolute hydraulic fi lter cartridge on the suction side of a pump. T is is accomplished without wash-off of collected particles as seen with standard magnetic fi lters, suction strainers or standard hydrau- lic fi lters. With negligible risk of pump cavitation,
the Magnom PumpMate removes fine ferrous and some nonferrous materials to sub-mi- cron levels and has a very high contaminant holding capacity.
