Hatch Cover & Shell Door Tightness Testing Tool

Operators can check cargo access sealing system condition at any time, with no water hoses involved and no interference with other shipboard activities, using MacGREGOR’s new Sherlog ultrasonic testing system. An efficient, reliable and convenient ultrasonic testing system for checking the tightness of key cargo access equipment – such as hatch covers and shell doors – has been introduced to allow surveyors swiftly to locate and assess a leak site without guesswork. Sherlog also features a data transfer capability to a PC or laptop, and can be used as a periodic survey information source.

Sherlog combines an ultrasonic detector and multi-transmitter to provide an accurate and reliable tool for testing the tightness of hatch covers, bow-, stern-, side- and inner doors and ramps, bulkheads, bulleyes and windows. The important features offered by this system are:

no risk of damage to cargo in the hold, unlike hose testing

reliable in most weather conditions, even below 0°C

no water hoses involved, and no interference with other shipboard activities

operators can ascertain cargo access sealing system condition at any time

easy and tamper-proof logging of sealing system condition

PC connectivity for data transfer to PC/laptop

The compact handheld detector and support system are configured for ease of use. Any leakage data can be registered and downloaded to a PC for easy reporting and safe logging, as required by IACS Z17 and classification societies.
