About North Sea Systems
North Sea Systems, formerly Green Theme, was established in 2010. We provide innovative design solutions to support the marine renewables industry. We are experts in systems engineering and highly experienced in designing electro-mechanical systems for the marine environment. We have developed two patented systems to help bring down the cost of offshore construction work, DataFish® and CableFish®.
DataFish® addresses a growing requirements for met-ocean information within the expanding marine energy and offshore wind industries. We have the capability to not only offer our proprietary high flow survey device, but also provide data analysis services, ensuring we offer customers a complete solution to their tidal and wave survey requirements. There are unique challenges faced when working and collecting data in some of the toughest marine energy sites in the world. The DataFish® survey device has been designed specifically to counter these challenges, consisting of an innovative buoy design that maximises buoyancy, minimises drag and allows a relatively light weight mooring to be used as the anchor. Our objective is to provide our clients with reliable, accurate data at the right cost, on every occasion.
CableFish® is a tool dedicated to touchdown monitoring of subsea cables. It provides continuous video and mapping of the touchdown point even in shallow or high flow environments – when the ROV cannot. The system is also significantly lower cost to operate than ROVs with a much smaller mobilisation footprint. When operated in automated mode it only requires two operators for 24hour operations.
