UNIC crane with a double-purchase whip for lifting the sea cage, which in turn may be dumped into the scow or large hopper bins. These are then transferred ashore for disposal of the collected contents.
The deckhouse is relatively small and very spartan, with only a small bench seat at the rear for crew. The main conning position is very well appointed, from the KAB sprung-loaded helm seat to the well laid out dash panel with all engine gauges and controls, the main switch panel and aids to navigation are close at hand. The SeaMac windows are reverse sheer in the front to eliminate glare while giving added space at the conning position, while the remaining windows all afford all-round vision, much the same as you would expect in a tug or work boat.
Rubbish wash down water cannon
evolution of ideas from past and present vessels in the ES fleet. There were many innovative ideas for gathering and handling rubbish, such as the moon pull system centrally mounted between the hulls on the aft deck for gathering floating rubbish. The waterjet system assists in directing the flotsam and any floating rubbish into the centre, where it is caught between the hulls by a large retrieval cage which is lowered by the crane.
An hydraulically operated bow loading ramp is ideal for landing beach cleaning teams and the muck truck, which is something akin to a motorised wheelbarrow or cart. The ramp may be swung across the hulls for stowage when not in use Also for'ard is the main deck-mounted water cannon for washing rubbish off rocks and ledges. It may also double in spreading oil dispersants when dealing with minor oil spills.
Aft of the wheelhouse is a general-purpose hydraulic extending
Innovations In Motion supplied and commissioned a TMQ C-Drive electric steering system which was specified and selected to control the vessel. One of the requirements of the design centered around the size of wheel and required turns lock to lock. With a conventional hydraulic system, the load on the wheel would have been excessive when sized at six turns lock-to-lock. The C-Drive allowed one turn lock-to-lock using an electric helm, so steering response is faster and lighter, offering less fatigue for the skipper.
The C-Drive unit controls a constant running pump set, driving twin steering rams with hydraulic synchro-valves for accurately aligning the twin rudder setup. The steering package was one of the key requirements in the specifications that the Australians were very specific about.
The electronic package, also supplied from Australia, included a Garmin 15in touch screen multi-function display, with a Garmin GPS Map 5015. Also linked in is a Garmin GMR 18HD 36-mile 4kW radar and a Garmin GSD 22 sounder. Communications are
