Sea mine protection of ships and submarines
Modern sea mines or torpedoes detect different underwater signatures of a vessel, like acoustics, pressure, corrosion and magnetic field. The trigging moment is mainly decided by the magnetic field signature with certain condition criteria’s provided by the other signatures.
As ships today operate much closer to the influence mines the threat increases. Better Degaussing systems than previously used is therefore a necessity. The answer to this increased threat is ADG, which means in principle 3-dimentional degaussing coil structure, one degaussing amplifier per coil on a steel hulled vessel with direct control from two 3-axis magnetometers.
Typically, 90-95% of the ship's signature can then be neutralized.
ADG is also ideal for the modern principles of section building of ships. The location of the Degaussing System components is very flexible and there is no need for a dedicated console operator to run an ADG. The console function can be one of many other programs in an appropriate workstation aboard the ship.
Vessels operating very close to the mines are made in non-magnetic materials like GRP/CF or stainless steel. Still they need to be equipped with a Degaussing system. On such vessels the coil system has a combination of ADG area coils and component coils.
Aluminium vessels have issues with stochastic created Eddy current magnetic fields. (*)
- Degaussing systems suitable from the smallest vessel to aircraft carrier, as well as submarines
- Turnkey capacity including system design, equipment delivery and proof trials
- Effective magnetic signature management with control, evaluation and prediction using SWECADE software suite
- Modular and digital open systems can be upgraded for future threats levels
- Favorable total cost of ownership
- Cost-effective procurement
A Polyamp ADG is normally controlled by one or more magnetometers to achieve a low signature. Several backup modes are available, including the Gyro Geomagnetic map and manual, depending on the design of the system.
The ADG signature adjusts by changing loop coil currents. Worldwide operations can be maintained without having to change connections on junction boxes or to control everything before the operational area.
The ADG design process is much faster, especially when using SWECADE © extensive data acquisition and measurement software with coil modeling.
Remote control from the ranging office can be achieved, quickly and safely by simply connecting a transceiver to the DG system.
The Polyamp's powerful ADG system enables significant savings on the overall cost of installation and weight to be achieved using smaller and thinner coil cables. This is of great benefit to the shipyard.
