MOCASSIN

Monte Carlo Sound Beam Intensities
U-31 (S181) is the first Type 212A submarine of the German Navy...It was built by TKMS at the shipyards of Thyssen Nordseewerke of Emden and Howaldtswerke at Kiel. The baptism took place on March 20, 2002, and the submarine was ceremonially put into service along with its sister ship U 32 by German Minister of Defence Peter Struck in Eckernförde on October 19, 2005. U 31 is powered by one diesel engine and an electric motor driven by nine fuel cells, making it virtually undetectable...Korvettenkapitän Bert Petzold is the submarine's commanding officer.

The challenge

Underwater situational awareness is paramount for successful maritime operations. It enables a clear understanding of submerged environments to ensure the safety of naval vessels, divers and marine life.

Comprehensive awareness enables the detection of potential threats, the identification of underwater obstacles and the continuous monitoring of changing conditions, thus enhancing the tactical advantage of military forces.

Accurate situational awareness allows for timely decision-making, effective navigation and a swift response to emergent threats. Prioritising underwater situational awareness is paramount for military organisations in order to secure their missions, protect their assets and uphold maritime security.

Our solution

MOCASSIN, short for Monte Carlo Sound Beam Intensities, is a cutting-edge sonar range prediction model created as a result of the collaborative efforts of the German Armed Forces and NATO.

Widely adopted by the German Navy, MOCASSIN stands out as one of the most advanced operational tools in the field. Its essential functions include the seamless integration of all monitoring system components, for example the incorporation of key data such as water salinity and temperature, and the automated calculation of sonar performance.

With MOCASSIN, naval operations benefit from accurate and efficient sound beam intensity predictions, which enhance situational awareness and decision-making capabilities.
