Over 600 offshore drilling platforms for oil and gas are on duty in the North Sea. Yet the wells are gradually running dry. The task is now to dismantle the installations by 2040 in a way that is both environmentally friendly and affordable. State-of-the-art twin hull vessels are deployed for this purpose. For maximum performance of the ship’s engine a durable, high-tech hydraulic system is needed that is capable of withstanding high working pressures in the saline environment. Any defects result directly in costly maintenance and repair. The main power transmission elements are the piston rods in the hydraulic cylinders.
