Introduction
This manual provides the Kongsberg Maritime maintenance recommendations and instructions for the
SR and SV type steering gears. All recommendations are provided in relation to general Class
requirements and guidelines.

Maintenance overview
Kongsberg Maritime (KM) steering gears are designed for safe operation with a minimum
maintenance. To prevent unexpected problems or downtime, it is recommended that the users
maintain the steering gear system at regular intervals.
For scheduled class survey and general service or repair, it is recommended to use Kongsberg
Maritime service engineers. This will decrease the time of repair to a minimum and ensure
continuous safe operation.
This document describes all relevant maintenance procedures and activities to be carried out by the
crew, in addition to the maintenance recommended to be performed by Kongsberg Maritime
engineers. Any other information may be found in the steering gear OPERATING AND MAINTENANCE
MANUAL (USER MANUAL) or by contacting
After a certain number of years in operation it is, however, necessary to service the equipment and
replace internal and external wear parts in order to achieve a predictable and safe life-cycle for the
steering gear equipment. The service intervals are depending on factors such as:
•
Alignment of rudderstock and steering gear
•
Radial forces from rudder and the operation profile of the steering gear
•
Oil temperature, pressure and oil condition
•
Duty cycles and degrees travelled
•
Other conditions such as DP operations
•
General maintenance
It is important to monitor the condition and performance of the equipment and take notice of any
changes. This might be important to reveal any problem about to develop before a breakdown
occur.
Note!
It is requested that any failures or maintenance work on the equipment, no matter how small,
should be reported to Kongsberg Maritime at;
By reporting, any failures and maintenance work, an accurate equipment history can be maintained.
This history will be continuously monitored and compared to other vessels with similar equipment.
With this information, we can provide better service, faster delivery of spare parts, and guidance for
preventive maintenance.
