The DB3000 is the largest data buoy platform in the portfolio, featuring a 3000mm diameter hull designed for advanced marine monitoring applications. Its substantial buoyancy and stability make it ideal for supporting sensors, data loggers, telemetry units, and complex ocean monitoring systems, including multi-instrument arrays and high-power scientific payloads.  

Developed as part of the Seagull buoy range, the DB3000 is built using a modular base composed of four interlocking polyethylene quadrants, combined with a reinforced central steel core that links the lifting and mooring eyes. This engineering provides outstanding structural strength, ensuring reliable long-term performance in demanding offshore environments.  

Features & Benefits

Specifications
