Matrix has produced and supplied High Gain Measurement System (HGMS) array buoys to the US Navy.
The two arrays are being used to support testing at the Carderock Division, Naval Surface Warfare Center (NSWCCD) Acoustic Research Detachment (ARD) in Bayview, Idaho. Tests are conducted in Lake Pend Oreille, a 1200ft deep freshwater environment. The buoys will be deployed continuously for a 15-year service life at various lake depths.
Matrix supplied a set of buoyancy modules consisting of three main types:
1) 4000 lb (1814kg) uplift array support buoys.
2) 3540 lb (1606kg) uplift array tension mooring buoys.
3) 1000 lb (454kg) uplift array compensation buoys.
The modular design of Matrix buoys meant bespoke elements were kept to a minimum. This resulted in buoys with very efficient weight and uplift characteristics which culminated in a strong value proposition for the customer. All of the through members were designed in accordance with and all material met the requirements of DNV 2.7-3. The buoyancy easily met all of the requirements of API16F and exceeded the customers' requirements for long term immersion.
