• Stoppers should be located bet'jVeen 2 ,7 and 3.7 metres inboard from the bow fairlead (See
  Figure A4).


• When positioning, due consideration should be given to the correct aligrtment of stoppers

  winch/ capSUUl.


• Stopper suppon structure·s should be trimmed to compensate for any camber and/or rake
  of the deck. The leading edge of the stopper base plate should be faired to allow for the
  unimpeded entry of the chafe chain into the stopper.


• Jmproperly sited stoppers and/or ancillary equipment will hamper mooring operalioru and
  may result in ships being rejected from terminals until such lime the arrangements have been
  modified to conform with these recommendations.


• Upon installation bow stoppers should be test loaded to the equivalent SWL and a test
  certificate issued. The test certificate should be available for inspection on board ship.


• The bow stopper and supponing deck and underdeck structure should be inspected periodically.
