TESTING HATCH COVERS TIGHTNESS--ULTRASONICALLY
The water-hose test that is used as part of an on-hire survey to check the seaworthy condition of hatch covers involves a great deal of time and effort on the part of the ship's staff and the surveyor. This article explains why MacGregor-Navire is therefore promoting the use of ultrasonics as an easier way of accomplishing the same purpose. After a transmitter is placed in the hold, a hand-held detector operated from on top of the hatch covers can determine whether or not the covers are watertight and can identify the location of any untightness.
