REPORT CONTINUED A total of four hydraulic motors (two above and two below) position the landing stage precisely alongside the passenger gate. Several hundred meters of steel piping and countless hydraulic hoses were installed after prior testing with pressurized oil by Hydraulikhuset to the applicable marine standard. The hydraulic cylinder for horizontal positioning alongside the ship and neatly arranged hydraulic lines are clearly visible on this gangway (one of six). Each gangway has a central hydraulic unit containing the pumps, control system and valves, and the hydraulic oil tank and filters. The hydraulic cylinders move the multi-tonne gangways to exactly the right position. Rapidly biodegradable OEKOSYNT HEES biofluid is used to operate the hydraulics, located right next to the harbor basin.

With each project successfully completed, the participating companies lay a cornerstone for even more big ideas. TTS Marine and Specma Hydraulikhuset have since taken the lead on further projects in Scandinavia, the UK and other locations in Europe. However big plans for hydraulic systems may get, MOTOREX plays a key role in transforming big ideas into perfectly functioning realities. • Watch the video on the Värtahamnen port expansion project 12 MOTOREX MAGAZINE 106 I DECEMBER 2015 13
