About the hull unit location
Selecting the best possible location for the hull unit is of vital importance for the overall sonar performance. The location of the hull unit must be selected by a skilled naval architect or engineer with experience in sonar theory and hull unit installation. Kongsberg Maritime can assist if required.
The information here must be considered as general advice. Each installation must be handled separately depending on the hull design.
The physical location of the hull unit depends on the vessel's design and construction, how the hull is shaped, and how the water runs along the hull. Observe the following considerations:
1 The sonar room must be accessible under all conditions at sea or at a berth.
2 The size of the hatch must allow the entire hull unit to be removed without being disassembled.
3 Heating is an effective method for reducing humidity. The heater in the sonar room must be dimensioned to maintain the equipment within its environmental tolerances. Typical heating power is minimum 1000 W. The heater must be installed close to the deck.
4 If it is not possible to connect the sonar room to the vessel's bilge pump system, a separate bilge pump for the compartment must be installed.
5 The sonar room must be connected to the vessel's ventilation system to ensure a supply of cooling air. If the vessel is likely to operate in tropical conditions, an air dehumidifier is strongly recommended to reduce the likelihood of corrosion due to condensation.
