Context
The mounting flange must be mounted so that its top mating surface is in parallel with the sea surface during normal operating
conditions. The transducer dock on top of the gate valve must remain vertical during the same conditions.
The top mating surface of the transducer dock must be protected with a wooden cover at all times until the hull unit is installed. It is very important that this surface is clean and undamaged, because it must be watertight after the hull unit has been
installed.
Objects protruding from the hull will generate turbulence and flow noise. This will reduce the CS90 performance. Protruding objects may be zinc anodes, transducers or even the vessel's keel. Holes and pipe outlets are also important noise sources, as well as rough surfaces caused by bad welding. Even traces of sealing compound, sharp edges, bolts or empty bolt holes will create noise.
The following requirements must be met:
|
• |
All measurements are made and the results are written down. |
|
• |
The top of the transducer dock is in parallel with the water line. |
|
• |
The top mating surface on the transducer dock is clean without sand, dust or any other destructive particles. Is is even and
smooth without scratches, dents or other physical damage. |
|
• |
The gasket or O-ring on the top of the transducer dock is not damaged. |
|
• |
The installation of the gate valve has left enough space to access end switches and (if relevant) hydraulic connections. |
|
• |
If relevant, the hydraulic system has been installed as specified in the relevant documentation. |
|
• |
The hull plating surrounding the mounting flange is even and smooth without protruding objects that can cause noise. |
|
• |
All necessary preparations have been made to design and install sufficient support brackets. |
Further requirements
If the inspection reveals errors, inaccuracies or unfortunate dispositions related to units, devices or cables, use the Installation remarks form to document these. If necessary, write a full report, and attach high resolution photos.
