Netherlands-based OSD (Offshore Ship Designers) has designed a new series of high-performance tractor tugs which can be used for a wide range of functions, including escort operations, harbour towage, ship handling, offshore mooring and berthing.
The basic model tug has a LOA of 33 metres and a beam of 13.5 metres, but the tug design can be tailored to various sizes. The high forecastle deck ensures good sea-keeping performance. The hull is shaped with side wings to reduce drag, enhance stability and to improve roll-damping. This makes the vessels perfectly suited for offshore towing and salvage.
