per-Steps to take

All work in the rig's risk area requires certain precautions:

• The electric motors and diesel engine must be switched off during fault finding

• Hydraulic, pneumatic and water systems must be depressurised with diagnosis and

• The rig's electric power supply must be disconnected and locked during fault ing and work within the rig's risk area (plug unplugged and socket locked with a

• When diagnosis or work in the rig's risk area is to be performed, all components which can be moved or continue moving must be secured, by supports or strap-ping before the diagnosis or work is started

Special procedures

Exercise extra caution and accuracy when fault finding diagnosis or other work is to

be performed at the same time as when one or more of the following points are cable:

appli-• the electric motors are started

• the diesel engine is started

• the hydraulic pumps are running

• the rig's power supply is connected (plug is connected)

• the hydraulic system is pressurised

• the pneumatic system is pressurised

• the water system is pressurised

If one or more of the above criteria must be fulfilled in order to carry out fault finding

or certain work then special steps must be taken:

• The work must be carried out by at least two people, one of which must be at the operating station and have a good view of the work

Fire fighting systems

Ansul and Forrex

The fire fighting system Ansul has a dry powder as extinguishing medium while rex has an extinguishing fluid Both systems are used to extinguish any engine fires.The fire fighting system is not designed to extinguish all types of fire, especially large collections of flammable materials with ample supplies of oxygen It is there-fore necessary to provide additional means of extinguishing residual fires should the fire fighting system not succeed in extinguishing it completely

For-Principal components

Both fire fighting systems comprise the following main components:

• activators

• start gas cartridge

• drive gas cartridge

• container for extinguishing medium

• extinguishing nozzles, located around the diesel engine and battery
