• | All relevant literature is available. |
• | All relevant vessel drawings are available. |
• | Detailed information is available about other systems on the vessel that may cause noise or interference. |
• | You have good knowledge about hydroacoustic systems and the challenges related to physical installation of these. |
1 | Determine the physical location of the transducer. The decision must be based on:
Make sure that all possible considerations are made to reduce noise.
|
2 | Determine the installation method. The transducer can be installed using one of the following methods:
|
3 | Based on the chosen installation method, design the mounting hardware. |
4 | Prepare a suitable hole in the vessel’s hull.
|
5 | Prepare and install the necessary cable conduit from the top of the transducer to the sonar room. Start the conduit immediately above the transducer, and terminate it well above the water line. Observe relevant requirements and guidelines from the maritime classification society.
Important
If you use a drop keel, the transducer cables must be properly fastened at the bottom, and fully supported while lowering and hoisting the drop keel. The cables must be permitted to move freely when the drop keel is lowered and hoisted. It is important to avoid sharp edges or protruding elements, as these may cause damage to the cables.
|
6 | Unpack the transducer from its transport crate. |
7 | Position the mounting ring in the hole prepared for it, and weld it in place. |
8 | Position the transducer under the mounting location. |
9 | Pull the transducer cables up through the steel conduit. |
10 | Mount the transducer. |
11 | Consider applying a thin layer of anti-fouling paint to the transducer face. This is recommended if your vessel will operate in waters with a lot of marine growth.
|
12 | Connect the transducer cables to the Transceiver Unit. |
13 | Record the location and installation angles of the transducer. The physical location and the installation angles of the MS70 transducer are important for the MS70 data accuracy.
