Auxiliary machinery / services / systems

Being all electric and with “spare” space located throughout the vessel means that auxiliary machinery and systems can be dispersed with the added benefits of improved safety combined with generally lower installation costs.

The main auxiliary machinery / systems include:

• HFO fuel storage and treatment with two separate P&S systems installed.
• Exhaust scrubbers with two separate systems P&S installed in stacks and aft of main machinery spaces
• EVAC vacuum sewage plant with 3 systems installed any one of which can service all ships needs.
• Reverse osmosis fresh water makers with 3 systems installed any one of which can provide all the daily fresh water needed (also used for ballast).
• Two back up 16 tons per day fresh water evaporators.
• Chilled water air conditioning systems with multiple VRF systems to allow for wide ranging loads.
• 2,000m³, about 600 tons, of deep freeze / refrigerated storage with four separate machinery systems.
• The hi-fog system with at least 9 pump / accumulator units to provide minimum 300% redundancy.
• Oily bilge water treatment + storage with two separate systems.
• Two vertical electric 75KW anchor windlasses installed in two separate WT compartments.

With most of these systems located outside the main machinery spaces, either at or near the tank top or in the core and as close to users as possible to reduce piping and delivery needs.

In the main machinery spaces generally auxiliary machinery / systems are limited to those directly serving the main generators or propulsion, however, some such as compressed air for engine starting are also used to provide “working” air through out the vessel.

The only significant non electric systems onboard are the local, but still electrically driven hydraulics for the lifts and the 100 ton aft crane, with all operating using non flammable type hydraulic oil.

Electronic systems including most navigation and communications are located mainly in a specially protected space aft of the navigation bridge or in the post office / bank adjacent, and in the control room.

Various surveillance systems are based / mainly in the control room but with remotes at the bridge, Captains cabin and the reception area.

Within individual apartments auxiliary systems include for hot water heating, FW pressure and air conditioning with only umbilical connections into the main systems run in the core, for low voltage electricity supply, fresh water and vacuum sewage suction.

Piping systems, with associated pumps, generally run in the hull and mainly via the central core with branch connections to spaces served at each deck.
