8.1.1 Approval of a Turbine Condition Monitoring Scheme is based on plan
approval of the main propulsion steam turbine arrangements, in accordance with LR’s
ShipRight Procedures for Machinery Planned Maintenance and Condition
Monitoring. For existing ships, a review of maintenance and condition
monitoring records is normally required, so that the initial condition of the steam
turbine can be assessed.
8.1.2 The ShipRight TCM descriptive note will be assigned to the ship.
8.1.3 The Chief Engineer should ensure that:
- The approved scheme is effectively implemented;
- Maintenance and monitoring records are maintained;
- Records are made available to the attending Surveyor at Annual
Audits.
8.1.4 Chief Engineers may not credit the steam turbine in LR Class Direct.
8.1.5 The Surveyor will confirm the correct operation of the scheme and satisfactory
functioning of the steam turbine at Annual Audit, harmonised with the classification
Annual Survey.
8.1.6 The Chief Engineer’s condition records will, subject to confirmatory surveys, be
sufficient for the Surveyor to ‘X’ Credit the steam turbine at five-yearly surveys,
without the top casings being lifted for examination of the rotors and diaphragms.
8.1.7 If the Surveyor is not satisfied with the operating condition or any aspect of the
scheme’s operation, they may request that items be opened out for inspection.
8.1.8 If deficiencies in the operation of the scheme are identified, either from the
maintenance and monitoring records or from the general condition of the machinery,
the attending Surveyor may advise that a further Audit will be required and impose a
suitable Condition of Class. In the event of serious deficiencies, a report will be
forwarded to the Classification Committee recommending that approval of the scheme
be withdrawn.
