The shipyard worked closely with Groupe Ocean and the supplier of the consoles and electronics package, Techsol, to modify the bridge and aft end design to enhance side and rear visibility using the same Virtual Reality technology the yard used to develop their OPTI-Max harbour tug design.

Measuring 30.8m by 11.14m with a 5.5m draft, the LR classed tug is powered by two Caterpillar

3516B HD diesels, each developing 2,500hp at 1,600rpm. Rolls-Royce Aquamaster US255 Z drives with 2.4m CP propellers are installed, providing a maximum bollard pull of almost 60 tons.

Auxiliary power is provided by two Caterpillar C9 gensets developing 165kW each.

For towing and anchor handling operations, a set of 200mm towpins is installed in conjunction

with a 150 ton Ridderinkhof aft towing winch and stern roller. The frequency controlled aft winch is a single drum type complete with spooling gear, capable of storing 762m of 51mm wire.

The 150 tonne Ridderinkhof electric line handling winch on the raised foredeck is capable of storing 400’ of 3 ¼ Spectra line.

A slightly raised forecastle provides enhanced performance in a swell without compromising the

tug’s ability to get close under overhanging bows and sterns. A curved deck edge allows the tug to be easily driven away from a ship’s side.

Comfortable accommodation for seven persons is provided by one single cabin and three double cabins.

Two remote controlled FiFi monitors supplied by FFS capable of a discharge of 1,200m3/h each are fitted just aft and above the wheelhouse. The monitors are supplied by a dedicated pump of 2,700m3/h capacity, driven off the front end of the port main engine. A water curtain

of 300m3/hr is also supplied by the pump, or alternatively foam can also be supplied at 300m3/hr.

Below the waterline, tug is fitted with a large ‘escort’ keel forward to provide effective indirect

towing capability and enhance course keeping, especially when running astern. Bilge keels have also been fitted for improved ship motions.

The forward end of the skeg has been fitted with an ice stop, designed to prevent the hull riding up onto the ice. The aft end is fitted with two ice diverters to prevent large pieces of ice from damaging the Z-Drives.
