Emergency equipment:

Emergency Generator:

Mostly fitted in the emergency generator room located in the upper deck . It has its own fuel tank, starting batteries and F.W. expansion tank.It is cooled by fresh water which is circulating in closed system and cooled by air fan fitted in front of a radiator. Its design should be considered to supply enough power to run emergency equipment.

Emergency fire pump:

Mostly located on deck , it has separated suction line from sea , Its discharge goes to main fire line. Some ships have small diesel engine to run emergency fire pump and some can be operated by emergency generator power supply .
 

Emergency steering :

Steering hydraulic pump may be powered by emergency generator and operated from bridge, also,Manual operation can be done from emergency steering station and communication is made with bridge by using emergency communication system.
 

Emergency compressor:

Located in the engine room near to air reservoirs, some types are manually operated and some can be driven by small diesel engine.
 

Deck Machinery:

 

Deck cranes:

Used for loading and discharging cargo, also can be used for opening hatch covers.
 

Anchor winches :

used for releasing and pulling up anchors.
 

Mooring winches ( capstans):

Picture3
used for tighten mooring ropes during ship berthing. Gangway winches: used for lifting up and releasing down gangways
 

Life boat winch :

Picture5
used for dropping life boat to water and lifting it back. Deck machinery construction requirements:
It should meet the following requirements  1- SWL ( safe working load ). 2- Can be stopped at any position. 3- Good holding brakes. 4- Motion direction can be reversed. 5- The speed can
6- Easy to use.
