Report Deliverable D5

This Report Deliverable D5 presents the results of Life Cycle Assessment (LCA) and Cost Bene-fit Analysis of Marine Coatings Applied to Fishing Vessels with regards to fouling accumulation on hulls and maintenance of ships. The methodology is based on mathematical models vis-à-vis the environmental and monetary impacts in-volved in the application of hull coatings, added fuel consumption due to fouling accumulation on ship hulls. The LCA methodology was developed using the re-sults of the studies conducted by EU FP7 Project FOUL-X-SPEL Consortium as well as additional data provided by coating manufacturers, shipyards and ship-ping companies.

Following the introduction of the LCA model, a case study was carried out to show the advantages of using an antifouling coating using a real fishing vessel which has 2 different surface conditions, namely a surface with no protective ma-rine coating which reflects the existing practice in Indonesia and a surface coated with an existing tin free self-polishing antifouling paint. The total fuel consumption costs due to these different surface conditions were calculated for the whole life-cycle of the fishing vessel. It has been found that CO2 emission reduction due to mitigation of fouling can be achieved using tin free self-polishing antifouling paint while reducing the cost by means of fuel cost reductions for the ship-owners despite the additional capital expenses. The developed LCA model can help artisanal fishing community determine the most feasible paint selection as well as the optimal hull-propeller maintenance schedules and make condition based maintenance decisions.
