Ultrasonic hatch cover testing: an update

Page 6 of Issue 82 of Signals Newsletter provides an article of ultrasonic hatchcover testing.

Ensuring a ship’s hatch covers are weathertight is an essential aspect of exercising due diligence to make a ship seaworthy and cargoworthy. This requires an appropriate method of testing to enable any potential problems or defects to be identified and resolved. In this article Walter Vervloesem of IMCS Group, and training instructor for SDTIMCS Ultrasonic Hatch Cover Tightness Testing Training course, compares the principal methods of testing hatch cover weathertightness.

This help sheet was enclosed with the April 2010 issue of Signals Newsletter.

Proper maintenance of hatch covers is esential if they are to be operated effeciently and kept weathertight. However, hatch covers can be complex pieces of equipment and maintenance is adjustment requires knowledge and experience. North has already publisheda loss prevention guide Hatch Cover Maintenance and Operation as well as a loss-prevention briefing to assist seafarers with this task. To provide further help a laminated help sheet is included with this issue of Signals. The aim is that the sheet will be readily available for use on deck and provide a guide for inspection. This wouold help identify problems before they become a serious threat and alert the maintenance team to intervene as soon as possible. It also provides an illustrated guide to common problems associated with sealing arrangments.

Hatch Cover Supplement

This supplement was made available to North of England P&I Members in the 58th Edition of their Newsletter Signals. It offers insight into surveying hatch covers and the top ten hatch defects.

“The Association may periodically require a ship’s hatch covers to be tested for weathertightness. Similar surveys are also often required by classification societies, and representatives of cargo shippers, particularly where the cargo is sensitive to water damage. These surveys may be done by the traditional hose test or using the more modern method of ultrasonic leak detection.”

Turkish Discharge Fines

An article on page 9 of Signals on the fines imposed by Turkish environmental authorities for discharges from ships which is calculated on a set amount according to the vessel’s tonnage.

Omur Marine, the Association’s correspondent in Istanbul, has recently issued advice to Members as to how to avoid pollution fines, as follows.

“No deck washing or hatch-cover hose testing should be performed in port or at anchorage. Ultrasonic testing of hatches can be carried out in Turkish ports. Members are advised to notify the Association of any need for hatch testing as far in advance as possible so that the necessary ultrasonic testing can be arranged.”
