Planned Maintenance System (PMS) Logbook (1st Edition, 2026)

This Planned Maintenance System Record Book provides a structured record of preventive maintenance activities carried out on board, covering all principal shipboard machinery, equipment and systems. It supports compliance with the maintenance and documentation requirements of the International Safety Management (ISM) Code.

Produced in accordance with:
- International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended - Chapter I, Regulation 11 'Maintenance of conditions after survey' and Chapter IX 'Management for the safe operation of ships'

- International Safety Management (ISM) Code ' Section 10 'Maintenance of the ship and equipment'

- International Association of Classification Societies (IACS) Unified Requirement Z20 - 'Planned Maintenance Scheme (PMS) for Machinery'

Classification Society Requirements: IACS Unified Requirement Z20 (Rev. 2 2019) requires that, under an approved Planned Maintenance Scheme (PMS) for Machinery, any repair or corrective action carried out on PMS-covered machinery shall be recorded in the PMS logbook (Z20, 3.3.2).

The PMS logbook forms part of the documented evidence that the classification society's surveyor reviews during the Annual Audit to verify that:

• The repair has been carried out to the Society's satisfaction,
• the PMS is being correctly operated, and
• the machinery remains in satisfactory condition.

While this record book does not itself constitute a class-approved PMS, the entries it contains (particularly the repair and corrective-action records required by Z20) support both the Company's maintenance procedures under the ISM Code and the evidence required for class and statutory verifications.

Systematic use of this Planned Maintenance System Record Book enables the Chief Engineer and engineering officers to:

• Maintain a record of preventive maintenance activities across principal shipboard systems.
• Demonstrate compliance with ISM Code Section 10 during flag state, port state and ISM audits.
• Support the identification, tracking and close out of defects.
• Facilitate planned maintenance scheduling and handover between engineering watch teams.
