Equipped as a trench cutter, the machine can work in up to five meters of water. A CLEAN SOLUTION For KÅREHAMN In 1997 Sweden’s wind energy production capacity was just 127 MW. By 2012 it had rocketed to 3,745 MW! Building wind power plants, often in geographically exposed places, has repeatedly required highly innovative solutions. Read how MOTOREX became part of the solution for the Kårehamn wind park. Sixteen wind turbines are scheduled to begin supplying electricity to some 50,000 households by the end of this year. The Kårehamn offshore wind farm belongs to the E.ON energy group. Modern Vestas turbines give it an extremely high efficiency. With a mast height of 80 meters, the wind turbines are anchored in a gentle arc in the open Baltic Sea at a depth of eight to 20 meters of water. To counter the danger that ice could form in the shallow waters off the island of Öland, the cables for the wind park are being laid in an 80-centimeter deep trench. Since there was no trench cutting machine in Sweden capable of doing the job, the Baltic Offshore construction consortium commissioned MOTOREX customer Växjö Hydraulservice AB to develop and build one. Mastering the machine’s complex controls is no easy task. By using extremely precise GPS coordinates, its exact position can be determined to within five centimeters. THE KÅREHAMN TRENCHER The machine’s engineering was so unique that the trench cutter was named after the project. Starting with a Volvo EC460 tracked excavator, the ingenious Växjö Hydraulservice AB team converted the machine in its own shop to meet the customer’s needs. One advantage was that all of the trencher’s functions are hydraulically driven. The engine, tanks and hydraulic and electrical systems were mounted along with the operator’s cab on 16

Stockholm ESTONIA SWEDEN Göteborg LATVIA Windfarm Kårehamn LITHUANIA Operating safety and environmental protection are top priorities during use at sea at distances of up to five kilometers from shore. THE KÅREHAMN TRENCHER: Length: 10.5 meters Width: 4 meters Fording depth: 5 meters Weight: 40 tonnes Rexroth pumps drive some 380 liters of OEKOSYNT HEES through the underwater trencher’s hydraulic system at pressures of up to 280 bar. a platform that can be hydraulically raised and lowered. Depending on the depth of the water, the platform can be raised by joystick up to six meters from the sea bed to keep it above the water line. Hydraulic lines elegantly convey the machine’s power output from the platform to the oil motors, trench cutter and other hydraulic components on the sea floor. 380 LITERS OF OEKOSYNT HEES Since the trencher operates in the water, using a rapidly biodegradable hydraulic fluid was a must. MOTOREX met the challenge with its OEKOSYNT HEES bio-fluid. OEKOSYNT HEES far exceeds the biodegradability requirements of OECD Test 301B, which prescribes 60% decomposition within 28 days. But besides its environmental friendliness, the product has yet another decisive advantage: because it is based on saturated synthetic esters, it boasts a considerably longer service life than mineral-based hydraulic oils. Special additives give OEKOSYNT HEES substantial performance reserves, reduce wear and help prevent disastrous hydraulic breakdowns. And when the trencher isn’t in use, its entire hydraulic system is also ideally protected against corrosion. Växjö Hydraulservice AB is an official MOTOREX reseller, working with MOTOREX to offer customers valuable services such as oil analysis and maintenance and lubrication plans. “MOTOREX OEKOSYNT HEES is both a practical and economical solution for us.” Christian Almerin, co-founder, Växjö Hydraulservice AB SHOWCASE PROJECT For the Växjö Hydraulservice AB team, the lubricant supplier’s technical expertise and consulting services are a top priority. Besides meeting these requirements, MOTOREX has proven with OEKOSYNT HEES that the perfect solution exists for any lubrication challenge. By creating the Kårehamn trencher in line with the final customer’s specifications and meeting all operating fluid requirements, the two companies succeeded in creating a fascinating showcase project. • MOTOREX MAGAZINE 99/50 I JULY 2013 17
