2 Application and Definitions

  2.1 These Guidelines apply to ships as specified in SOLAS regulation II-1/3-11 and focus on maintenance and repair procedures for coatings in cargo tanks of all crude oil tankers, hereinafter referred to as "crude oil cargo tanks" or "cargo tanks that are intended to carry crude oil". They only cover the maintenance and repair of coatings. Corrosion prevention systems other than coating are not covered by these Guidelines.

  2.2 For the purpose of these Guidelines, the following definitions apply:

  • .1 Maintenance means minor coating restoration work regularly performed by a ship's crew using normal shipboard means and tools to maintain "GOOD" or "FAIR" coating conditions. Maintenance delays or slows down the coating deterioration and effects short term steel protection.

  • .2 Repair means coating restoration work of a longer term nature, usually performed during ship's dry-docking or scheduled repair period (ship idle) to restore the "FAIR" or "POOR" coating condition to "GOOD" condition. This will usually require specialized preparation, manpower and equipment such as blasting equipment, operators and dehumidifiers together with good surface preparation procedures.

  2.3 These Guidelines have been developed using the best information currently available and taking into consideration that maintenance may take place when the ship is at sea, while repair usually takes place in dry dock or during scheduled repair periods (afloat at yard).
