What to know for Winterisation and Layup

Prepare an engine for layup and recommissioning without creating avoidable corrosion or freeze damage.

Fuel, cooling, oil, batteries, belts, corrosion, ventilation, and recommissioning. This module is mapped to the published course boundary for Marine Diesel Engine Revision and written as an independent revision aid, not official training material.

Key Points

  • Layup protects fuel, cooling system, batteries, and metal surfaces
  • Antifreeze procedures must match the cooling system
  • Batteries need charging and isolation planning
  • Recommission with checks, not assumptions
