Installing the cable gland
In order to secure the vessel’s watertight integrity, it is extremely important that the transducer cable penetrates the ship’s hull in a safe manner. One suggested method is to use a cable gland. The cable gland consists of a bushing, rubber gasket, washers and a packing nipple.
Prerequisites
Before you can install bushing, the following prerequisites must be met:
•  The transducer cable must be fitted with the rubber gasket, washers and packing nipple.
•  The installation arrangement has been approved by the relevant authority.
•  All relevant personnel (skilled shipyard workers, ships electricians) and relevant tools must be available.
Context
These items are all provided as a part of the transducer delivery.

Procedure
1 Depending on the chosen installation method (blister or tank), make a hole for the bushing.
2 Weld the bushing to the steel plate.
3 Verify the quality of the weld.
4 If relevant, allow the maritime authority and/or classification society to inspect and approve the installation.
Further requirements
Before you can put the transducer cable through the cable gland, the steel conduit must be installed.
