Turkey's Uzmar Shipyard Launches World's First LNG Dual Fuel Propulsion Tractor Tug, Sultanhani

Uzmar Shipyard, based in Istanbul, Turkey, has launched a unique tractor tug for BOTAS, a Turkish operator.

The vessel, dubbed the Sultanhani, was launched on 27 February as the first Voith-propelled tractor tug operating on liquefied natural gas (abbreviated as LNG) dual-fuel propulsion.

It is the first of the two hulls manufactured for BOTAS using Robert Allan Ltd.’s design of TRAktor V3900-DF.

The TRAktor V3900-DF is based on Robert Allan Ltd.’s experience designing both LNG dual fuel tugs and Voith tractor tugs.

It combines remarkable manoeuvrability with the dependability of Voith propulsion in a greener package where the tug may run on diesel oil or LNG.

Even while using diesel oil, the emission is reduced using an after-treatment system based on IMO Tier III.

Owing to the forward location of the structure’s VSP units, the LNG tank hold is placed aft of the engine room, offering separation of the gas system and the associated hazardous zones from the accommodation block.

The overall length is 39 m.

The beam (Moulded) is 15 m.

The depth (Moulded) is 6 m.

The LNG capacity is 40 m3.

The diesel oil capacity is 164 m3. The power is 2 x 3000 kW. The predicted Bollard Pull is 80 tons.
