| Abstract |
The definition of success in coating usage is meeting the expectations. As such it is vital that the end user have a clear idea of what these expectations are. The providers cannot be the ones that decide on the expectations. Coating data sheets offers a range of choices in terms of surface preparation and application conditions, all of which may not generate a performance that meets the expectations. The painting manufacturers are under pressure to make things easy for the constructing yard, and there is nothing wrong with that as long as the final product also meets the needs of the ship. If the intent of the application is make something look good only during a visit of a dignitary, and the ship is to be retired soon after a minimum approach is highly appropriate. However, if it is a new ship with a 25 year service life expectancy a more robust approach is the more cost effective approach. This presentation will focus on the common modes of failure and what can be done at onset to offset those risks to increase the chance of meeting the expectations of a 25 year performance of the coatings applied. Much of the discussions will touch on ballast tank coatings as the performance of those have an influence on the ships' service life. |
