OBJECTIVES

• To perform testing and establish documentation on
  performance of last generation tin-free
  anti-fouling paint systems, based on test patches
  on ship in normal operation.
• Ship owners to participate by offering test ships
  and arrange for test areas.
• Major suppliers of anti-fouling paint systems to
  participate with their last generation tin-free
  products, designed for the actual ship and trade.
• The composition of test ships to be sufficiently
  broad to reflect operational conditions for the
  world fleet both regarding trades, trading
  waters, speed, activity levels, docking intervals
  etc, also most demanding operational conditions
  for anti-fouling systems to be covered.

SURFACE PREPARATION OF THREE CATHEGORIES

• TBT based anti-fouling to be applied on top of
  old intact TBT based anti-fouling. Paint
  suppliers are offered test areas for their TBT
  free products.
• TBT-free anti-fouling to be applied on top of old
  intact TBT-based paint, eventually with sealer.
  One paint supplier will be main, other suppliers
  are offered test areas for their TBT-free
  products. 
• Full sand blasting of hull, full anti-corrosive
  and TBT-free anti-fouling to be applied,
  conditions as for new ships. One paint supplier
  will be main, other suppliers are offered test
  areas for their TBT-free products.

TEST AREAS AND LOCATION

• All test areas are located mid-ship, and
  preferably at the same side of the ship
• For ships with single side loading arrangement
  test areas should be on the side facing the sea.
• Vertically test areas should go from deep load
  line to the bilge keel
• Horizontal width of each test area should not be
  less than 3 m.

• Preliminary conclusions
• Ten vessels have been reported and six of them
  have their trade in cold Nordic waters. From
  these reports some preliminary conclusions can be
  drawn
• The new types of Anti Fouling systems developed
  due to the ban of Antifouling based Tributyl
  Tinoxide (TBT) polymers has proven to solve the
  fouling problems to about the same degree as the
  old TBT based systems. Whether the new types are
  more or less efficient is too early to conclude,
  however, the new types seem to polish at a
  slightly slower rate in cold waters.
• Weed fouling in cold waters has shown to
  represent problems for several of the products
  tested.
• The efficiency against fouling between the six
  product types/producers has shown some slight
  differences, each of them has performed the best
  on at least one ship. Hence it is too early to
  draw any definite conclusion.

REPORTING, INTERMEDIATE AND FINAL

• Reports are scheduled as follows
• Preliminary Reports, covering mainly preliminary
  results from short docking intervals were issued
  May and October 2003
• Intermediate Report, covering all but 60 months
  systems is planned November 2004
• Final Project Report, planned December 2006
