EFFECTS OF HULL FOULANTS AND CLEANING/COATING PRACTICES ON SHIP PERFORMANCE AND ECONOMICS

The ship performance parameters affected by hull roughness are reviewed, and the components of hull roughness are discussed. Data are presented for the principal hull cleaning and coating systems that are available for consideration in selecting a hull surface management practice for a particular ship and operating profile. The Hull Performance Assessment Model (HPAM), a computer simulation for the comparison and optimization of hull surface management practices, is described. Representative HPAM analyses are presented for a break-bulk ship, a containership, and a tanker. Also presented are the results of sensitivity analyses which show the variation of optimum hull cleaning and coating schedules, and their attendant ship performance and economic benefits, with respect to ship speed, fuel cost projection, port fouling severity, time at sea, and cargo load factor. Practical applications of hull surface management techniques are discussed, and the potential benefits of theoretical advancements in concert with full-scale correlation efforts are addressed in the particular context of improved hull performance predictions.
