BS IEC 61892-5:2010 pdf free download Mobile and fixed offshore units – Electrical installations Part 5: Mobile units
This part of lEC 61892 specifies the characteristics for electrical installations in mobile units,for use during transfer from one location to another and for use during the exploration andexploitation of petroleum resources.
lt applies to all installations，whether permanent, temporary，transportable or hand-held, toa.c. installations up to and including 35 000 v and d.c. installations up to and including1500 v.(a.c. and d.c. voltages are nominal values).
NOTE Attention is drawn to further requirements concerning electrical installations on such mobile offshore unitscontained in the MoDu CODE of the International Maritime Organization (IMO).

3 Terms and definitions
For the purposes of this document the terms and definitions given in IEC 61892-1,lEC 61892-2,IEC 61892-3,IEC 61892-6 and the following apply.
3.1
auxiliary steering gear
equipment, other than any part of the main steering gear， necessary to steer the unit in theevent of failure of the main steering gear but not including the tiller, quadrant or componentsserving the same purpose
3.2
dynamic positioning (DP) system
equipment necessary to provide means of controlling the position and heading of a mobileunit within predetermined limits by means of resultant vectored thrust
3.3
electric steering gear
power operated steering gear where an electric motor applies torque to the rudder stockthrough mechanical means only
