3 GENERAL DESCRIPTION

AUSRAL AERO-MARINE SDN BHD are naval architects expert in fast vessels and the design of the ID-156 AMBULANCE BOAT is evolved from proven craft that have been supplied to a variety of commercial agencies.

The ID156 AMBULANCE BOAT is of closed-cabin configuration with the hospital laid out in accordance with guidelines of DIN EN 1789 CATEGORY B Road ambulances. Windows are designed to give the crew & patients excellent external views to minimise the effects of motion sickness. The catamaran asymmetric hard chine hull-form with HYSUCAT hydrofoil system provides a very comfortable platform for its role in the transport of patients in coastal waters. The HYSUCAT will provide 30-50% lower impact accelerations than a comparable catamaran or monohull. The hydrodynamically optimised HYSUCAT allows for efficient operation at its design speed and loading condition. The horizontal at-rest trim angle coupled with the large aft deck area with a crane and boarding gates on both port and starboard sides make it easy and comfortable for the loading and unloading of patients and their effects. The position of the engine compartments coupled with full noise-damping cladding in the engine compartments minimise noise and vibration carried to the hospital and pilot house.

The catamaran hull-form exhibits excellent stability characteristics in both the intact and damaged conditions. This provides for an outstandingly seaworthy craft with predictable and easy handling at all speeds and loading conditions. The hull is divided into sufficient separate watertight compartments with at least the following:

Steering compartment

Machinery Space

Fuel Void Compartment

Forepeak

Her modern design allows for operation in conditions up to Sea State 4.

The ID156 AMBULANCE BOAT is constructed primarily of aluminium alloy materials employed in the marine industry which are accepted and approved by the major international classification societies. Her durable, robust and stable design with solid framing make her capable of withstanding all the operating loads imposed on her during transit, loading/offloading and mooring operations under all expected conditions.



She is powered by twin CAT C9 ACERT engines (375kW each) coupled to ZF286 gearboxes. With standard production diesel engines, she is capable of reaching 33+ knots at full load condition at 85%MCR. Propulsion is by waterjets or surface drives.

The diesel fuel is contained in fully-baffled separate heavy-duty tanks which are situated in such a location in the vessel as to minimise the effect of trim during the depletion of the fuel.

The design complies with International Classification Society Standards for ‘day passenger vessels’ operating in harbour and coastal areas. As reference, the DNV rules for High-Speed Light Craft will be employed for the design.

5 PROPULSION MACHINERY, CONTROLS AND SYSTEMS

5.1 MAIN ENGINES

The craft is powered by standard specification Caterpillar diesel engines rated at 503HP in accordance with ISO3046. The engines are sea water aftercooled and suitable for operation at

ambient temperatures of 45C air and 32C seawater, where there is a 3% derating of power and 1.5% increase in fuel consumption. Raw cooling water is fed to each engine from a standard through-hull raw-water inlet and via a seacock and in-line strainer. The water-injected exhausts are piped to the transom and terminate in exhaust tips incorporating anti water ingress flaps.

5.1.1 ENGINE DATA

Type Designation: CAT C9 ACERT Configuration: 4-stroke, 6 cylinder, in-line, direct injection,

turbocharged Displacement: 8.82 L Power: 503 HP (375 kW) @ 2700 rpm Aspiration: Turbocharged with water-cooled turbine housing Engine Mountings: Rubber Type Flexible Mounting Rating: D-Light Commercial

Each engine will be provided with fabricated 316 stainless steel wet exhausts connected to the outboard at the transom with cowlings above the load waterline. Exhaust pipes are sufficiently lagged with asbestos-free heat insulating material with outer cladding. Rubber hose connections are provided for each engine for absorption of thermal expansion and vibration. Exhaust pipes are flange jointed for ease of maintenance. Cooling of the exhaust pipes is by water injection after the turbo outlet. The run of the exhaust pipes are suitably looped to prevent water ingress into the turbo chargers. The lagging is of the removable blanket type.

5.2 TRANSMISSIONS

Each engine is fitted with a ZF286 direct-mount transmission. The transmission has a light duty rating of 386 kW at 3300 rpm.

5.3 PROPULSORS

OPTION 1: WATERJETS

The gearboxes are connected to Stainless Steel 316 shafts and Hamiltonjet HJ322 waterjets. Propulsors are so selected as to absorb the full power output of each engine at maximum attainable speed in full load trial conditions and to have optimum performance at service speed.

Design and manufactured to international standards, the HJ322 waterjet uses corrosion resistant materials which are further protected by fitting sacrificial anodes. The units are supplied factory tested as a complete package with integral steering and reverse control systems.



OPTION 2: SURFACE DRIVES

The gearboxes are connected to stainless steel shafts and Arneson ASD10 inline articulated surface drives. Propellers are surface piercing and selected to absorb full power of the engines at maximum speed in the full load condition.

The Arneson drives have their own hydraulic control system for trimming and steering the drives. Drives are fitted with Rolla or France Helice 5-bladed NIBRAL propellers.

5.4 STEERING

The steering system consists of steerable waterjet nozzles. The HJ322 waterjet has a steerable nozzle that deflects the jet stream to port and starboard, providing powerful and highly responsive steering. Steering is actuated via an inboard mounted tiller. A manual hydraulic system is preferred although less efficient rotary cable steering is optional. A split duct astern deflector is mounted aft of the steering nozzle, providing an infinite range of ahead, zero-speed or astern manoeuvring. Control is by a cable operated Hydraulic Servo Reverse Control (HSRC) system – a follow-up system where the astern deflector “follows” the control lever movement. The HSRC System comes complete with a jet unit mounted and driven hydraulic powerpack (JHPU) and oil cooler integral with the jet intake, eliminating the need for an external cooling supply.

Adequate emergency and backup features on the steering gear shall be fitted in accordance with the requirements of the classification society.

5.5 CONTROLS
