Sea suction strainers

  3.3 Taking into account the role of sea suction strainers as a secondary filter in the ship's ballast water pumping and piping system the design should minimize the mesh size of the strainers (without restricting the water flow to the ballast pumps). Consideration should be given to manufacture the strainers from stainless steel (preferably SUS 316L) to minimize the potential for corrosion of the strainers during service, and consequential loss of effectiveness as a secondary filter.

  3.4 Systems and procedures should be developed for the cleaning of strainers prior to any ballasting operation.
