HYDRAULIC SYSTEM (THRUSTER) FUEL SYSTEM The central hydraulic system will provide power forthe bow thruster, 2-foredeck windlasses and 2 aftcapstans. When running, each engine will power one Rexroth variable displacement marine hydraulic pump. The two foredeck windlasses will be hydraulicallypowered Muir VRC 4500. Electrical controls operated by hand or foot, viabutton or switch will be local to both windlass and capstan.Hydraulic and electrical isolation of this equipment iscontrolled via a deck function button situated on the bridge. If the deck function button is depressed, no oil will circulate until either one or both gearbox driven pumps or the AC power pack is activated.The 16" bow thruster, 1 windlass and 1 capstan willoperate at full thrust / pull with reduced line speed with both main engines running at 570rpm. Fuel is stored in the forward bunker tank integral with hull structure. Both main propulsion engines and generators draw and return independently from/to the daily service tank.This tank shall be replenished, via transfer pumpfrom the bunker tank. This pump can be set to automatically replenish the daily service tank, activated at preset levels from the tank level sensors and is capable of transferring circa 45l/min of fuel. In the event of failure there is a hand operated pump.Bunkering to forward tanks will be through individualfilling stations, port and starboard which have an audible alarm fitted. This alarm will be activated at 90%.Daily service tank and forward tank(s) are fitted withtank level sensors and level alarms. The sensors are manufactured by Kubler and supplied by Tijssen in order to ensure complete compatibility of the system.Emergency fuel shut-off valves will be fitted tosupply piping to main engines and generators, located on daily service tank. Valves will be remotely operated and actuated from the fire control locker with local manual override. HYDRAULIC SYSTEM (STEERING) The steering system will operate via a dedicated electro/hydraulic package. The main components of which are located in the port side of the garage area. The main steering gear (tillers and steering

Sunseeker 34 Metre Yacht

FIRE SUPPRESSION AND DETECTION BILGE SYSTEM The accommodation areas of the yacht are to be fitted with both heat and smoke detector alarms and the machinery spaces with heat detector alarms.System alarm panels are to be positioned in thewheelhouse, crew mess / galley area and machinery control room.The fixed fire fighting system shall be a Seafire FM200 engineered system with a capacity to extinguish a fire within the engine room compartment. Hand held fire extinguishers are fitted in allaccommodation and machinery spaces. In addition a Fire blanket is fitted in the galley. A bilge system driven by a pump located in the garage (coupled to a manual start marine diesel engine) and a further pump located in the machinery space to ensure that in the event of any one compartment being flooded the other pump is available to control any leakage to adjacent compartments. An engine driven pump is also available.The machinery space is fitted with three bilgesuctions. One connected to the engine driven pump for emergency suction. One connected to the bilge manifold and one connected direct to the secondary bilge pump arranged so that it can be operated independently of the bilge manifold. All remaining bilge suctions are connected to the bilge manifolds in either the machinery space or the garage.Bilge discharge from either pump will be through adischarge manifold located in the machinery space and garage.Each bilge suction will be fitted with a detachableand easily cleaned strum box. The owner/captain of the yacht should be remindedthat they are responsible for retention of any oily water and oil residues onboard and the disposal of same ashore by recognized means – shore side tanker or the like. FIRE HYDRANT SYSTEM Fire Hydrant Arrangement 2 pumps will supply a minimum of 2 fire hydrants positioned to ensure coverage of all areas of the vessel. Fire fighting equipment (water) will be provided at fire hydrant points (sited in fire lockers) and will have fire hoses and nozzles with instantaneous connections and quick release valves.
