Kongsberg Maritime Embient, with KONGSBERG partner company Contros Systems and Solutions, have been selected to develop and deliver technologies and strategies for environmental monitoring during gas hydrate E&P as part of the EU Submarine Gas Hydrate Reservoirs (SUGAR) project, according to a news release.
Germany’s Federal Ministry of Economics and Technology started the third phase of the more than $12.6 million joint project SUGAR at the beginning of October 2014. The third phase will last three years and will lead into a European venture that aims to have worldwide impact for gas hydrates as a new energy source, the release said.
Kongsberg Maritime Embient is the main contractor, with Contros, in sub-project 4 of SUGAR, having been awarded the task of developing solutions for detecting and quantifying gas bubbles in the water column and creating leakage alarms autonomously, the release said. As part of this work, Kongsberg Maritime Embient will create a generic algorithm to collect and interpret data from ship-based sonars for easy leakage control of wide areas.
In the second step, an autonomous seabed monitoring system (Lander), based on the Kongsberg Maritime-developed modular subsea monitoring (MSM) network concept, will be developed in close cooperation with Contros and the Helmholtz Centre for Ocean Research Kiel (Geomar) at known gas emergence points, according to the release.
The Lander system will combine a multitude of different sensors (point sensors using passive and active acoustics), KONGSBERG cNodes for communication, quad packs for energy supply, and a data processing unit as the central part. The Lander will collect all data, process it, discern gas bubbles from other objects, generate an alarm in case of a leakage scenario and calculate a dispersion model of gas bubbles in the water column.
