Section 4 Machinery Condition Monitoring

4.1.1 Approval of a Machinery Planned Maintenance Scheme using Machinery Condition Monitoring is based on remote audit of the scheme details and an implementation audit, in accordance with LR’s ShipRight Procedures for Machinery Planned Maintenance and Condition Monitoring.

4.1.2 The ShipRight MPMS(CM) descriptive note will be assigned, and a Certificate of Operation of an approved Machinery Planned Maintenance Scheme and CM Annex will be issued to the ship.

4.1.4 Chief Engineers may carry out condition monitoring and examination of the selected machinery items, in accordance with the requirements of Lloyd’s Register’s Rules and Regulations for the Classification of Ships, July 2022, without the need for a Surveyor to be present.

4.1.5 The selected machinery items need only be opened out for maintenance, examination and survey when readings of condition and performance parameters indicate deterioration beyond defined limits.

4.1.6 All selected machinery items must be credited once in each five year period. Chief Engineers should manage the distribution of credits throughout the cycle.

4.1.7 Chief Engineers may ‘I’ Interim Credit the selected machinery items, using the ‘MPMS Crediting’ function in LR Class Direct, on the basis that condition monitoring data is satisfactory, maintenance is up to date and the applicable machinery item is in good working order.

4.1.8 The Surveyor will confirm the correct operation of the scheme and satisfactory functioning of machinery at Annual Audit, harmonised with the classification Annual Survey.

4.1.9 The Chief Engineer’s maintenance and monitoring records will, subject to confirmatory surveys at the Annual Audit, be sufficient for the Surveyor to ‘C’ Confirmatory Credit the selected machinery items for survey.

4.1.10 The Surveyor will ‘X’ Credit any items opened out for examination at the Annual Audit.

4.1.11 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.

4.1.12 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.
