SAES has offered advice and discussions on the measurement and control of ship noise at the Spanish Defence Technological Conference.

The event, held in Madrid on 15 June, has been chaired by the Defence Department in order to enforce the relation between the Spanish Naval Forces and the industry.

During the meeting, several matters were discussed such as the future Spanish frigate F-110 and naval weapons. SAES participated in the area dedicated to ship noise reduction, which is essential for the naval platforms. The company has explained some key issues based on its wide experience as well as the newest developments and solutions for measurement and control of ship signatures.

Measurement, control and reduction of the ship’s signature are strongly important to assess the ship security. SAES has explained that, although the acoustic signature is widest known, others must be considered. The multi-influence signature is composed by acoustic, electric, magnetic, seismic, and pressure influence, which all characterise the ship unequivocally.

Accurate measuring of the ship signature is a mandatory requirement for the signature reduction task. In order to achieve it, SAES has developed a multi-influence range system (MIRS). The system is an advanced portable system, which obtains the complete signature of a vessel. It can be used in various scenarios as it is portable and can be deployed wherever necessary. MIRS can be used as a discrete device to gather underwater signature intelligence information or as a tool to verify real-time ship signature levels when vessels are leaving the base.

SAES develops other systems to specifically measure the acoustic or electrical signature. The company provides tools and services for ship signature reduction by analysis, identification, modelling, and prediction.

SAES has been in charge of the measurement and modelling of the electric signature of the Spanish Minehunter and the acoustic and non-acoustic signatures of the S-80 Spanish submarine.
