Welcome to AMra

Advanced Magnetic Ranges Australia

What We Do

In the Defence environment, stealth is paramount. Deperming Systems can be used to reduce the risk of magnetic detection of steel hull vessels, both surface ships and submarines. Deperming cancels permanent magnetisation by creating a magnetic field by passing an electrical current through coils to reduce the magnetic signature of the vessel and protect her from magnetic detection by magnetic mines or by MAD system (magnetic anomaly detection). Advanced Magnetic Ranges Australia is about developing a solution that utilises a subsea system, using coils laid on the sea bed, rather than the traditional wrapping process. This system, allows the entire deperming operation to be reduced to as little as one day and reduce drastically vessel’s downtime.

AMRA’s proposed deperming system is an over-run treatment range for submarines and surface ships with:

  • Magnetic treatment of both submarines and surface ships
  • Fast treatment time
  • High precision of measurement and treatment
  • Ability to measure the complete signature of the vessel through vertical compensation coil (separation of induced and permanent vertical magnetisations by measurement and not by estimation)
  • Ability to be combined with range multi-influence
  • Degaussing system calibration and checking
  • Low maintenance needs

Overrun stations can operate without any cable-wrapping operations. The treatment loop and sensors can be fixed so displacement-related damages are avoided and maintenance is reduced.

Ship trajectory is determined with DGPS receivers and visualised with MapsDRS software modules. The over-run treatment range can be combined with a multi-influence range: acoustic, magnetic, electric, and pressure.

Advanced Magnetic Ranges Australia (AMRA) is an Australian-based company that is a joint venture between AMOG Ventures Pty Ltd and ECA Group. AMRA integrates the knowledge of these companies, acquired over a combined period of more than 100 years, to offer an advanced deperming solution for submarines and surface ships.

The ECA Group is renowned for its expertise in robotics, automated systems, simulation and industrial processes. Since 1936 it has been developing comprehensive and innovative technological solutions to perform complex missions in hostile or restrictive environments.

Its products are used by a demanding international clientele requiring the highest levels of safety and efficiency, mainly in the sectors of defence, maritime, aerospace, simulation, energy and industrial equipment. ECA Group has always been at the forefront of innovation ever since it was founded in 1936. It has built up the trust of its customers around the world thanks to the reliability and performance of its solutions, at minimum cost. Right now, our R&T teams are imagining robotics systems for the year 2020, to meet our customers’ needs even more effectively.

“Two of our strongest commitments are to innovate to find efficient and reliable solutions, and to support our customers when they operate our technical solutions” underlines Raphaël Gorgé, Chairman of the ECA Group.  This commitment to reliability and efficiency is put into operation by all the men and women of the ECA Group.  It is summed up by the group’s tagline: Make Sure.

AMOG is a leading global solutions provider to Defence and Defence Industry, as well as the energy, resources, transport and maritime construction industries.
