5.1 General
This system consists of carefully selected parts based on safety design. However,
periodical check (operation check) and maintenance described in the following section
must be performed for long term satisfactory operation.
Main purpose of the maintenance and check of the system are aiming to catch signs of
equipment failure at an early stage through continuous suitable maintenance and check.
By repairing on call at port based on results of these checks, occurrence of unexpected
situations and troubles in sailing will be prevented to a minimum.
For the maintenance and check of the connected equipment to this system such as the
automatic steering system, magnetic compass system, etc., refer to the separate
individual Operator's Manuals.
Please record in the log book, etc. content of these checks and maintenance that were
performed.
Procedures of the maintenance and check only for this system are explained in this
chapter. General precautions are as follows.
(1) Assign a person in charge of maintenance and check for this system and perform
those under his responsibility.
(2) Mechanical parts in connecting and fixing sections of this system such as case and
panel may be loosened due to body shock and resonance vibration. Check and
re- tighten the related screws at need.
(3) Most parts used in the main sections of this system are electronic (electric) parts.
Occurrence of electronic parts trouble themselves is very seldom, and troubles in
mounting sections of electronic (electric) parts, being about to disconnect wires at
roots or lead wires of electric parts, occur easily due to hull body shock or
resonance vibration. Accordingly these points are checked.
Re-fix these parts, re-tighten the fixing screws, reinsert the connectors, re-fix the
mounting parts, repair the cables and lead wires at need.
(4) If strange motions, smells, sounds and heat generation, etc. different from those in
normal operation exist, record those in the log book and request our service station
to repair at earlier stages.
(5) It is recommended that this system is checked periodically by our service engineer
or qualified engineer.The checked items in the check list table and the log book
should be also evaluated by the engineer.The trouble shooting and repair should be
carried out by the engineer according to the results of the checking up of the
troubled items.
5.2 Periodical check
Use the periodical check table for the periodical check.
Frequencies of the check are (1) items to be performed once a day, (2) once a half year /
once a year. Checked items are decided as normal or not by comparing with the values
at installation time on the ship as a standard.
