Kocaçay RAstar 3200SX

The RAstar 3200SX is a new variant of the proven RAstar Series of tugs from Robert Allan Ltd. Developed exclusively for Sanmar Shipyards; this new design has been optimized for cost efficient construction while still meeting the client’s need for customization.
The RAstar escort/offshore terminal tug designation is reserved for a distinctive class of very high-performance ASD tugs, designed with the unique sponsoned hull form developed exclusively by Robert Allan Ltd., which has been proven in both model and full-scale testing to provide significantly enhanced escort towing and seakeeping performance. Escort forces are enhanced by the effects of the sponsons as well as by the prominent foil-shaped escort skeg forward. Roll motions and accelerations are less than half those of comparable sized “standard” wall-sided tug hulls.
RAstar tugs will typically be high-powered, intended for demanding escort operations in exposed areas such as many LNG terminals where a high standard of seakeeping is required.
RAstarseries tugs are classified according to their approximate length, e.g. RAstar 3200 (32 metres lengthl. and a range of powers can be accommodated within each hull size according to the specific operational needs. Accordingly there may be beam variations with the same length.
