Lay-up Process

Plan, Prepare & Preserve

Before a vessel arrives, we start the lay-up process. Our motto is ‘Plan, Prepare and Preserve’.

Planning for an arriving vessel helps eliminate costly mistakes which can extend a lay-up.

Planning is essential to help control the lay-up process. Vital information needs to be communicated, and expectations need to be managed. Equipment needs to be ordered and service providers put in place.

The following demonstrates our planning process:

Lay-up step by step

Scope of agreement

  • Determine areas to be dehumidified.
  • Agree who is responsible for delivery of standard services.
  • Request additional services, such as anodes or mooring blocks.
  • Decide whether the vessel will be laid-up at the anchorage, or alongside a wharf.
  • Agree on a demobilisation plan, based upon services required.
  • Agree on pricing.
  • Sign a contract

Pre-arrival checklists

  • Write operating procedures for equipment.
  • Supply certificates and drawings.
  • Complete and return all checklists.
  • Clean and prepare in readiness for arrival.


  • Sound tanks, then sign for Remains on Board.
  • Mobilise equipment for the vessel.
  • Set up for watchmen to live aboard.
  • Begin demobilisation of crew.
  • Transport equipment from vessel as required.
  • Remove rubbish and combustibles.
  • Install lay-up generator, and put vessel in dead ship mode.


  • Shut down systems systematically for preservation.
  • Start blanking spaces to be dehumidified.
  • Clean areas and stow equipment, if a cold lay-up.
  • Divers blank hull penetrations.
  • Fit suspended anodes as required.
  • Fit dehumidifier trunking, and start machines.
  • Monitor spaces to ensure fast pull-down of humidity.
  • Write routine maintenance procedures, if a cold lay-up.
  • Write and submit lay-up report.
  • Write reactivation plan.

Lay-up routines
