Vessel Reactivation

Vessel Reactivation

A Reactivation Survey is required for vessels returning to active service from lay-up, regardless of whether or not ABS was informed that the vessel has been in lay-up or if lay-up preparations were reviewed by ABS. The primary objective of the Reactivation Survey is to verify that the vessel is in conformance with the applicable Rules and requirements.

The ABS Guide for Reactivation of Laid-up Ships outlines the precautions and procedures suggested to re-commission a vessel. The guidelines for applicable surveys are as follows. Full details can be found in the ABS Rules for Survey after Construction, Part 7, Appendix, Section 3.

1. Hull & Outfit
2. Machinery
3. Electrical
4. Control & Instrumentation
5. Trials
6. Documentation & Certification
7. Additional Items for Consideration

Owners may contact any ABS survey office worldwide for additional details.

1. Hull & Outfit
Drydocking Survey: Depending on the date of the last Drydocking Survey and the period and conditions of lay-up, an underwater inspection by diver may be permitted in lieu of drydocking for reactivation.

The following items, among others, should normally be included in the reactivation surveys of hull and outfitting:

  • Anchors, chain cables, stoppers and locker pumping arrangements
  • Anchor windlass, mooring winches and roller fairleads
  • Random cargo tankers, pump rooms and cargo piping
  • Peak tanks, random ballast tanks and respective pumping systems
  • Cofferdams and voids, with their pumping out arrangements
  • Fire extinguishing arrangements to be verified in order
  • Foam tank solution to be tested and replaced as necessary

2. Machinery
The following items, among others, should normally be included in the reactivation surveys of machinery and inspected for inhibitors, corrosion, excess wear and/or damage:

  • Stack and ventilation covers to be removed or opened up
  • Boilers, heat exchangers and piping systems to be drained and cleaned of preservatives, inspected and closed up
  • Turbine rotor journal and thrust bearings should be at least selectively examined for corrosion effects
  • Functional operation of seals, drains; low-oil-pressure, manual and overspeed trips to be confirmed
  • Thrust bearings, lineshaft bearings and respective lubrication arrangements to be checked
  • Diesel engines and their accessory gear to be selectively opened out and examined
  • All required fire extinguishing arrangements to be reconnected and examined

3. Electrical
Insulation resistance of all power and lighting circuits together with generators, motors and switchgear, should be tested. Generators should also be tested under operating conditions. Switches, circuit breakers and electrical protective devices should be verified.

4. Control & Instrumentation
All essential control systems, monitoring instrumentation, limit alarms and emergency shut-offs are to be verified in order.

5. Trials
In addition to the operational tests of individual units of machinery, a dock trial, and subsequent sea trial if deemed necessary, should be effected to the satisfaction of the attending ABS surveyor.

6. Documentation & Certification
The validity of the following statutory and/or trading documents should be checked and updated or renewal surveys should be carried out, as necessary:

  • Cargo Gear Register
  • Safety Construction
  • Safety Equipment
  • Safety Radio
  • Loadline
  • Oil Pollution Prevention
  • Air Pollution Prevention
  • Dangerous Chemicals
  • Liquefied Petroleum Products

Additional statutory documents that should be in place and up-to-date include:

  • Oil record book
  • SOPEP plan
  • Engine technical files
  • Engine record book of engine parameters

For ships out of service for more than three months, ISM and ISPS audits will be required. It is also suggested that possible changes or revisions in international convention requirements since the time of lay-up or in the interpretations of these requirements by the registry Administration should be checked.

7.  Additional Items for Consideration
The following items should also be given consideration at the time of reactivation:

  • Necessary supplies, spare parts and consumables
  • Cleaning, recoating and flushing potable water tanks
  • Internal corrosion removal and recoating
  • Mooring lines and hawsers
  • Gangways and boarding ladders
  • Cargo gear
  • Specialized equipment related to the type of cargo carried such as tank filling instrumentation or gas leak detection apparatus
