The Italian tug owner has ordered a new terminal-class vessel from Sanmar Shipyards for its fleet modernisation programme
Rimorchiatori Napoletani ordered another azimuth stern drive (ASD) tug from Sanmar Shipyards to support terminals in Italy. This will be built to a Robert Allan RAstar 2800 design and could be delivered as early as May 2021. Sanmar said this will be a sister vessel to Baia, which it delivered in May 2020 to Rimorchiatori Napoletani’s operations in Naples.
The 28.2-m escort tug will have around 82 tonnes of bollard pull and a speed ahead of 14 knots. Two Caterpillar 3516 C main engines will each produce 2,525 kW at 1,800 rpm, driving two Kongsberg US255 thrusters with 280-cm diameter, fixed pitch propellers.
Sanmar said this terminal-class tug was designed for escort operations in all weathers in exposed areas where a high standard of seakeeping is required.
Robert Allan incorporated a sponson in its design to enhance escort forces and foil-shaped escort skegs on the hull, which has proven to be more stable and enable escort forces through full-scale testing and computer modelling.
“It means roll motions and accelerations are less than half those of comparable-sized standard tug hulls,” said Sanmar.
Sanmar is completing its Terminal XXIX tug with a moulded beam of 12.6 m and draught of 5.3 m for Rimorchiatori Napoletani’s requirements. It will have a fire-fighting system classed to FiFi1 with a dedicated diesel Caterpillar C32 generator coupled to one fire pump with a capacity of 2,700 m3/hr.
Enhanced accommodation was designed for crew welfare, with captain and engineer cabins on the top deck with ensuite washrooms, a mess, lounge and separate galley. Three double cabins below deck also have ensuite facilities.
“This is a powerful, multi-purpose escort tug which incorporates experience and unique forward-thinking design,” said Sanmar vice president Ali Gurun.
Four more Sanmar-built ASD tugs are in Rimorchiatori Napoletani’s fleet. Sanmar previously delivered two 50-tonne bollard pull, RAmparts 2200 design tugs, one 75-tonne, RAmparts 2400SX tug and another RAstar 2800 tug to Rimorchiatori Napoletani as it modernises its fleet.
