Our through hull deployment machine has been designed specifically but not exclusively for the deployment of our range of USBL transceivers and Sentinel Diver Detection Sonar devices.
The standard deployment machine has been designed to provide survey grade rigidity for use with USBL systems up to 71 knots with the ability to survive short duration exposure to higher speeds. For heavy duty installation where the pole is longer than 3 m or where operational water currents may reach 10 knots1, 2, the pole must be installed using Sonardyne’s heavy duty installation requirements. For specialist or demanding applications, machines of this general type can be custom engineered to suit customer specific requirements.
The Through-Hull Deployment Machine consists of an electronically controlled but hydraulically operated pole running through a sealed bearing section. A service section (or sea chest) is provided with inspection door to allow fitting and servicing access to the USBL transceiver or Sentinel devices.
The Through-Hull Deployment Machine has been designed to fit on to DN350 and DN500 gate valves however other gate valves are also supported. Hydraulic control of the gate valve is provided as an option.
Sonardyne can give detailed application advice on positioning, installing and commissioning the machine.
The machine can be controlled from a main control panel or locally at the machine. A bridge control is also available as an option.
The hydraulic power pack and main control can be mounted remotely if the machine is to be configured for Zone 1 Ex rated classification.
The standard form of machine can be simply configured to the meet individual vessel requirements by changing the height of the machine and providing adaptor flanges for different size or specification gate valves.
For specialist or demanding applications, machines of this general type can be engineered to suit customer specific requirements.
Our Lodestar Gyro-Compass and Motion Sensor can easily be mounted in the pole for Optimised USBL and DPINS applications ensuring mechanical coupling between the Transceiver and the Lodestar.
