Hoofddorp, the Netherlands-based ship designer OSD-IMT has expanded its range of tugs with the unveiling of a new multi-purpose tractor tug design.
OSD-IMT offer a range of services including refit and conversion projects and marine consultancy but it is its extensive range of specialist vessel designs that catch the eye, its portfolio mainly involving tugs and offshore industry related vessels.
The operational profile often determines the client’s requirements in the design of a new tug from standard off-the-shelf examples to bespoke variants and OSD-IMT’s latest addition, the Cyclotrac 3960 is marketed as “perfectly suited” for harbour towage and ship handling along with coastal towage and escort operations. With a nod to the increasing popularity of efficient and environmentally friendly operations it is offered in diesel direct, diesel electrical or hybrid with or without batteries.
The design features Voith cycloidal thrusters forward in tractor configuration providing a bollard pull of up to 90t and speed 12kn from twin 3,300kW main engines and principal dimensions include: LOA 36.7m, breadth 15m and maximum draught 7.8m. The option for fifi1 notation from two 1,200m3/hr monitors is included.
As typical with tractor tugs, towing is over the stern via a 250t brake load waterfall type winch. Deck crane, 100-ton SWL towing pins and 5t capstan are also included with accommodation provided for 10 persons. Wheelhouse equipment includes INMARSAT-C area A-3 GMDSS, electronic chart plotter, X-band radar and an EPIRB and SART.
The design has a hard chine hull for ease of construction with a large deep fin keel aft and high forecastle deck providing good seakeeping performance, the hull shaped to reduce drag and enhance stability.
In other news from OSD-IMT, PT Patria Maritim Perkasa (Indonesia) recently launched the first OSD-IMT7402 shallow-draught tug. Built to a conventional design, two 610kW Yanmar main engines power fixed-pitched propellers in nozzles with performance figures of 18tbp and speed 8-10kn. A towing hook is provided aft and fendering includes a push bow. As with the new Cyclotrac marque, accommodation is provided for ten persons.
Dimensions include LOA 23.6m, breadth 9.4m and minimum draught 2m allowing operation in water depths of 2.5m and this particular example will assist the berthing, unberthing and towing of 300’ barges along the Barito river in the South Kalimantan area of Indonesia.
