2 Application and Definitions

  2.1 These Guidelines apply to ships as specified in SOLAS regulation II-1/3-2.1.1 and focus on maintenance and repair procedures for coatings in dedicated seawater ballast tanks of all types of ships and double-side skin spaces of bulk carriers, hereinafter referred to as “ballast tanks”. They only cover in-service maintenance and repair of coatings. Corrosion prevention systems other than coating are not covered.

  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 manpower and equipment such as sand blasting equipment, operators and dehumidifiers.

  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).
