Safehaven's depth of engineering expertise is demonstrated by our Multi Beam deployment system The advantage of a catamaran when designing a deployment system for the expensive multi beam sonar head is that by deploying the sonar head through a moon pool in the catamarans bridge deck, a high degree of protection is provided by the twin hulls. The system is designed to lower the sonar head mounted on a 4m aerofoil design support to just below the vessels keel, operation is through a 2m stroke stainless steel cylinder with electro hydraulic operation mounted on the back of the wheelhouse on the aft deck, which lowers the head through a hatch integrated into the bridge deck forming a ‘moon pool’ the sonar head then extends down to below the keel line whereby sonar data can be collected at low speeds. For fast transit speeds the sonar head is raised and the moon pool hatch closed, whereby the vessel can again operate at high speed with the sonar head safely protected.
It is anticipated that the multibeam system to be fitted to the vessel will be either a Kongsberg 3002 or a Reson 8125, The system will be chosen for the engineering capabilities.
The
sonar will be mounted as close to the centre of gravity as possible.
Ducting will be provided for the cable to the survey position. The
diameter of this cable will depend on the chosen system, and an
allowance will be made for this in the design. The sonar will therefore
be mounted solidly to the hull. This will allow a minimum amount of flex
between the systems employed on the vessel, to ensure the accuracy of
the measured depth. Inertia Motion Sensor
It
is anticipated that an Applanix POSMV inertial aided motion unit will be
used to correct for the motion of the vessel. A mounting plate will be
fabricate for the unit. The
IMU will be mounted above the multibeam transducer Dual Frequency Single Beam Echo Sounder
The
anticipated preferred survey specification echo sounder for the vessel
is the dual frequency Reson Navisound 420 and associated transducer.
Ducting for the cable to the survey location will be provided. The
survey echo sounder will be used as part of the navigation requirements
using a repeater at the helm station. |
