| | | rams) can be accessed from this compartment. The system is actuated via the control panel located at the main helm. It is also possible to control the vessel using the steering wheel positioned at either helm console. All communication between the electro/hydraulic pack and the main helm position is electronic via a screened cable. This system will have semi - redundancy, since only one of the two matched 2.2kVY 415V AC electric motors are required to power the circuit. Either motor can be selected at any time to provide the hydraulic pressure and flow necessary to steer the vessel. In the unlikely event of a failure at the bridge it is possible to manoeuvre the vessel from the steering pack location using either motor. There is also a manual hydraulic helm position located adjacent to the port side of the garage area used to operate the steering system in the event of electrical failure. Communication to the bridge will be via a VHF handset and visual indication of the rudder position is given via a local reference gauge. The system will be monitored at the Wheelhouse to ensure compliance to classification where appropriate. The system will integrate with the autopilot. This is controlled via its own signal transmitted through a separate screened cable, giving yet a further level of redundancy. HYDRAULIC SYSTEM (AUXILIARY) An independent system located in the tender garage with local controls will operate the components below. A locally mounted manual pump, in the event of ships power loss, can also operate the system. Components • Oil tank, capacity up to 100 litres depending upon equipment specified • Tender garage door operation rams • Trim tab operation rams, power up & down The auxiliary hydraulic pack will control the following: • Tender garage door • Tilting platform • Trim tabs ELECTRICAL The standard main electrical panel located starboard aft of the engine room is built to RINA Pleasure Craft standard and comprises of two main AC power sections and a DC services section. | | Also mounted within the main panel is the Monitoring and Control system (MPA) touch screen and computer. A slave screen is mounted at the helm that mimics the main panel. All electrical systems are designed and installed in accordance with Classification Society standards. All electrical equipment is selected from ranges demonstrated to be suitable for marine use. Wherever appropriate, equipment is type-approved by the relevant Classification Society. All cables are selected from marine ranges. Where appropriate these are of a type approved by the Classification Society. Cable support is in accordance with classification society rules. All major cable runs within the machinery space are supported on metallic cable trays. AC SUPPLY & DISTRIBUTION Main AC Power Supply Boats to European Standards: 3 phase supplies - 400 Volts 50Hz 4-wire distribution with grounded neutral. Single phase supplies - 230 Volts 50Hz with grounded neutral. Boats to US Standards: 3 phase supplies - 400 Volts 60Hz 4-wire and 208 Volts 60Hz 4-wire distribution with grounded neutral. Single phase supplies - 120 Volts 60Hz with grounded neutral. IMPORTANT: It is the owners/operators responsibility to inform Sunseeker International of the area of operations of the vessel. Shore power voltages differ around the world, and in some cases shore power converters may be required in addition to standard specifications. Electrical power is supplied from two main generators. When alongside, power may be drawn from shore side connections via either an isolating transformer or optional shore power converter. Connection to the shore will be via a 20 metre shore cable capable of 100 amp per phase duty. This can be retrieved via a Gendinning Cable Master. | | |
