X - Condition based recommendatation:
The Condition based recommendation is based on several condition values reported through a mobile
application provided by KM to the customer to perform inspection of the steering gear equipment
themselves. The Mobile application contains a Self - Assessment, leakage and manoeuvre time test
and loading of SG PMS Log files by using our dedicated application – customer sync result back to KM
for recommendations, ideally six months in advance of the vessels planned class surveys or docking.
Steering Gear Performance Monitoring System (SG PMS):
The purpose of the performance monitoring system is to continuously monitor the performance and
operation of the steering gear, and provide an alarm when degraded or irregular performance is
detected. The SG PMS Amplifier card is part of the standard delivery for all new steering gears type
SR/SV - FCP, as of early 2019. The SG PMS solution is also available as an upgrade on all steering gear
installations completed in 2005 or later.
