4.1 As a condition of assignment, each open-top
containership should maintain fully operational hold dewatering systems,
including all system redundancies. The operability and condition of
the hold dewatering systems and freeing ports if they are fitted should
be inspected monthly by the crew and entered in the ship's log book
for annual verification by the Administration.
4.2 At each load line renewal survey, the Administration
should require that the hold dewatering systems be fully tested to
assure proper functioning.
4.3 The structural survey schedule requirements
for the open cargo holds should reflect that they are exposed to the
sea atmosphere. A complete inspection of the open cargo holds should
be conducted in conjunction with the load line renewal survey.
