Hydraulic Arrangement
Hydraulic Systems
The hydraulic transmission will be designed for optimum performance within the
constraint of available horsepower. High pressure hydraulic system uses power
more efficiently and applies power as needed.
All motions controls offer infinitely variable speed and full reversing characteristics.
Two full flow filters will be installed. The filter(s) will be adequately sized for full flow
operation without causing pump cavitation. Replaceable wire mesh filter cartridge
of minimum absolute value of 40 micron will be used. The pumps will have overflow
suction independent of the reservoir, and the arrangement of piping can avoid air
pockets.
Hoisting Circuit
Each winch is driven by a common open loop hydraulic system including piston
pump piston motor and epicycles gearbox. Each winch is fitted with oil immersed,
multi-disc and dynamically rated “fail safe” brake.
The fixed displacement hoist motors offer a constant operating speed.
Slewing Circuit
The slew circuit is driven by a common open loop hydraulic system. Dynamic
braking of slewing is by means of hydrostatic compensation. Similarly positive
locking brakes are fitted in the circuit and used as static brake;
Luffing Circuit
Luff circuit is driven by a common open loop hydraulic system. Each winch is fitted
with oil immersed, multi-disc,dynamically rated “fail safe” brake. an additional luff
ratchet cylinder is included, providing a positive means of locking the luff drum
whenever the prime mover is shutdown.
Hydraulic Piping
1. Pipes: No pipe threads will be used for the high-pressure lines larger than 3/8".
Hydraulic components that have pipe threaded ports lines will have a minimum
working pressure 300PS. .
2. Pipe fittings: Zinc plated mild steel material. External fittings are painted and
protected by Denso tape or equivalent against corrosion.
3. Hoses: High rubber quality for best resistance against sunlight and salinity,
Wire breaded for applicable specified hydraulic pressure ratings
4. Hose couplings: Zinc plated mild steel material, External couplings are painted
and protected by Denso tape or equivalent against corrosion
Hydraulic Oil Tank
1. Level gauge with isolating valve (to top cover)
2. Inspection and cleaning cover
3. Filter with fine mesh stainless steel strainer and ventilation
4. A relief valve will be installed in the discharge line of pump.
Cooling Circuit
The air-oil heat exchanger will be provided and sized to ensure continuous operation
of the crane under the ambient temperatures given on the data sheets.
Electric Arrangement
Standards, Codes and Protection
Refer to Codes Of Practice and Standards. The electrical systems onboard the crane
complies with these standards for good offshore electrical design and engineering
practices.
