Unique Degaussing System Feature

The world first Deagussing system with a semi automatic organic back-up system onboard a frigate type vessel was tested successfully during the Sea Acceptance Test (SAT) on the new Iver Huitfeldt class frigate of the Royal Danish Navy.

ADG Systems with a Semi Automatic Organic Back-up System

Thanks to the unique Polyamp ADG design and excellent cooperation with the Danish Defence Acquisition and Logistics Organization (DALO), the RDN now possess what is believed be the first ADG systems with a semi automatic organic back-up system onboard a frigate type vessel.

This is a full hardware back-up system for the ADG to be used in case of, for example battle-damages and it goes far beyond previously tried software back-up solutions. The ADG system is highly reliable but in the rare case where a power module should go out of order, the switch to a spare power module takes only a few seconds and the ships underwater signature is virtually unchanged. The new concept gives a Mean Time To Repair (MTTR) for the Degaussing System of typically less than 10 seconds and this is a record that will be hard to beat.

Polyamp has in fact, as a part of the same development concept, supplied a similar Backup system, with an ever higher level of automation for another, and smaller, RDN ships class.

That the successful design now has been demonstrated at the signature trials is the result of a long and fruitful cooperation between Polyamp and DALO that goes back as far as year 2003 when Polyamp took full magnetic signature responsibility for the Absalon class. The latest contract is however dated in July 2007 and it includes the delivery of ADG systems, including back-up functionality, for the three Iver Huitfeldt class frigates.

The ADG SAT was performed as a part of the underwater signature procedure performed at the Swedish Sea Range Station in Lysekil on the new frigate HDMS Peter Willemoes  That the RDN performs important Sea Acceptance Trials in Sweden is in itself a proof of the RDN confidence in the underwater signature know-how in Sweden where Polyamp is acknowledged and respected in the underwater signature control area.  

Polyamp Sweden Vice President Per Ennerfors: “This SAT demonstrates our capability in technology edged ADG systems deliveries while maintain the highest possible level of product technology as well as quality. We are proud of the excellent result and the very good and most creative relation with DALO and the Royal Danish Navy.”
