Product Overview

Summary: This Vessel Maintenance Safe Operating Procedure sets out a clear, safe and compliant approach to inspecting, servicing and repairing marine vessels in Australian workplaces. It helps organisations manage WHS risks around dry-docking, confined spaces, working at height and hazardous substances while keeping vessels reliable, seaworthy and ready for operation.

Vessel maintenance activities expose workers to a unique combination of marine, mechanical and WHS risks – from slips on wet decks and falls from height to confined space entry, hot work and handling hazardous chemicals. This Vessel Maintenance Safe Operating Procedure provides a structured, end‑to‑end framework for planning and conducting routine and non‑routine maintenance on commercial vessels, workboats and support craft operating in Australian waters. It aligns practical, day‑to‑day tasks with WHS obligations, ensuring maintenance is carried out safely, consistently and with full traceability.

The SOP guides users through pre‑maintenance planning, isolation and lock‑out of systems, inspection regimes, cleaning and painting, mechanical and electrical work, and post‑maintenance verification. It sets out clear roles and responsibilities for skippers, supervisors, contractors and crew, and embeds risk assessments, permits to work and toolbox talks into the maintenance cycle. By implementing this procedure, businesses can reduce unplanned downtime, demonstrate due diligence to regulators, and protect workers from preventable injuries while extending the service life and reliability of their vessels.

Key Benefits

• Ensure vessel maintenance is carried out in line with Australian WHS laws and marine safety expectations.
• Reduce the risk of injuries associated with slips, trips, falls, confined spaces and hazardous maintenance tasks.
• Standardise maintenance practices across fleets, contractors and sites for consistent, auditable outcomes.
• Improve vessel reliability and availability through structured inspections, defect reporting and sign‑off.
• Support training, onboarding and competency verification for new crew and maintenance personnel.
