Pulling the transducer cable through the sealing plate
In order to secure the vessel’s watertight integrity, it is extremely important that the
transducercables penetrate the ship’s hull in a safe manner. If you decide to use a sealing
plate, each transducer cable must be fitted with the necessary rubber gasket, washers and
packing nut. This task is only applicable if you use a SN92 or SN93 transducer with a
sealing plate and/or a "dry" conduit.
Prerequisites
In order to do this task, the following prerequisites must be met.
• All relevant work instructions, procedures and standards must be available.
• Each transducer cable must be fitted with the necessary rubber gasket, washers and
packing nut.
• The mounting house (or a similar construction) has been installed.
• A suitable sealing plate is mounted with all installation work finalized.
• If a steel conduit is used, it is readily mounted with all installation work finalized.
• If a steel conduit is not used, the compartment directly over the sealing plate is
watertight.
• All relevant drawings have been approved by the classification society.
• All relevant personnel (skilled shipyard workers, ship electricians) and their tools
must be available.
You must be equipped with a standard set of tools. This tool set must comprise the
normal tools for electronic and electromechanical tasks, such as screwdrivers, pliers,
spanners, a cable stripper etc. Each tool must be provided in various sizes. We
recommend that all tools are demagnetized to protect your equipment. The following
specific tool is required for this task:
• Fish tape (wire pulling tool) with suitable length
Context
Each transducer cable penetrates the sealing plate using a packing nut, a rubber gasket
and a washer.
