You must be equipped with a standard set of tools. This tool set must comprise the
normal tools for mechanical tasks, such as different screwdriver types, pliers, adjustable
spanners and wrenches. Each tool must be provided in various sizes. We recommend
that all tools are demagnetized to protect your equipment. Depending on the tasks at
hand, additional tools may be required. Observe the relevant rules and regulations related
to welding. The quality of the welding is critical to the safety of the vessel. Welding
must only be done by a certified welder.
Context
The installation shipyard must provide all necessary design and installation drawings,
as well as the relevant work standards and mounting procedures. If required, all
documents provided by the shipyard for the physical installation of the SN90 must be
approved by the vessel’s national registry and corresponding maritime authority and/or
classification society. Such approval must be obtained before the installation can begin.
The shipowner and shipyard doing the installation are responsible for obtaining and
paying for such approval.
Important
Finalize the steel conduit installation before you pull the transducer cable through it.
Make sure that there are no spatter, sharp edges or protruding objects that can damage
the transducer cables. If a cable is damaged, and penetrated by water, the transducer
will be damaged beyond repair.
The dimensions of the steel conduit must be specified and/or verified by the relevant
maritime authority and/or classification society. The minimum dimensions are:
•
Inside diameters
:
– With transceiver plug mounted: 182 mm
– Without transceiver plug: 110 mm
•
Steel conduit wall thickness
: 7 mm
•
Steel type
: Match the steel type used for existing decks and bulkheads
Procedure
1
Based on the vessel drawings, the physical properties of the decks and bulkheads,
and the physical locations of the transceiver and the transducer, design the steel
conduit.
The steel conduit must preferably be straight. Start the conduit immediately above
the transducer, and terminate it well above the water line. If you must introduce
bends on the steel conduit, take the size of the transceiver plug and the minimum
cable bending radius into consideration.
2
Manufacture the steel conduit according to the relevant production standards.
