Vessel | LAUNCH & DELIVERY
distributed around the superstructure, providing protection from the irradiated heat of the fire being smothered. The fire monitors are one for use
with water only and the other water and foam. The remote control for these is by means of a portable joystick panel, allowing the waterjets to be directed from anywhere in the after end of the wheelhouse. Forward, the vessel has a Schottel
transverse thruster of 600kW, resiliently mounted for minimizing the noise transmitted into the vessel, and aſt , fi tted within the skeg, there is a tunnel thruster of 400kW. Both tunnel thrusters can be driven
independently by dedicated controls both at forward and aſt control stations, or alternatively in conjunction with the main propellers and steering systems by means of a Masterstick joystick system, supplied by Schottel.
Technical equipment T e twin propellers combined with the high liſt fl ap-type rudders and in together with the electrically driven bow and stern thrusters, give the ship excellent manoeuvrability and necessary control for station keeping and tracking, when centrally controlled by the Masterstick joystick system. All propulsion units can be operated
by means of their individual controls from the fore and aft stations in the wheelhouse, as well as from the independent joystick system provided, which has one fi xed control panel in the aſt console, and a portable panel with connection at bridge wings and forward console of the wheelhouse. To meet the latest IMO requirements
regarding pollution prevention the propulsion engines have been manufactured and have certifi cates of compliance with exhaust gas emissions criteria. Similarly IMO compliant sewage treatment plant and a bilge water separator have been fi tted. The bridge deck
houses all
vessel controls, navigation systems, communication equipment and the vessel system alarm and monitoring panels, supplied by Noris. The ship’s electrical power is supplied
14
by two main generating sets. These are sited in the engineroom between the forward main engines. The generating plant is composed of two Caterpillar 3408TA generating sets capable of producing 370KWe at 1800rev/min each. There is also a Volvo D7A-T rated at 100kW emergency/harbour generating set fitted on the forecastle deck. Additionally to these, there are two water cooled Leroy Somer shaft alternators of 1200Kwe, driven by the aft main engines.
Accommodation T e living area is divided in two levels with the traffi c control deck above and wheel house being the fourth deck. T e working crew’s quarters are sited at main deck level, and primarily consist of three two-man cabins plus a four man cabin, with shared washroom facilities. Forward on this deck is the galley with
refrigerated provisions rooms adjacent to it and both offi cer and crew messes/ day rooms, for the crew to enjoy in the off duty hours. Additionally on this main deck is a
hospital with direct access from deck and a reception at the accommodation entrance day rooms, changing rooms are also provided. The forecastle deck holds the
comfortable and spacious captain and chief engineer and owner representative cabins, as well as other offi cer cabins and guest cabins, all of them with their washroom facilities. T e ship’s offi ce is also on this level.
Lifesaving On the field control deck
a
comprehensive set of navigation and communications systems have been supplied for the traffic control officers to perform their duties. Additionally there is a poisonous
and explosive gas detection system panel and an addressable fire detection panel. When the second level of the gas detection system is activated all ventilation stops and the air inlet louvers are closed. For rescue operations, the vessel is
provided with one Maritime Partner ‘Springer’ fast rescue craft, capable of achieving in excess of 30knots when loaded with 15 men. The FRC is launched and recovered by a Hydramarine hydraulically-operated davit with 4.5tonne lift capacity to allow for the fully laden craft to be raised. Other appliances for rescuing
survivors from the water are the scrambling net for the rescue zone, and a Cosalt rescue basket both of which are operated from onboard the vessel, and do not require any of the ships crew to leave the safety of the vessel, in adverse weather conditions. SBI
