C-Worker 7

Description

C-Worker 7 is a multi-role work class ASV suitable for a variety of offshore and coastal tasks. The vehicle can be used to complete tasks such as subsea positioning, surveying and environmental monitoring without the need of a ship on station or sea-bed anchoring. C-Worker 7 can integrate a variety of payloads including multi-beam, USBL, CTD and ADCP via exchangeable payload frames. The ability to integrate multiple offshore payloads is unique to C-Worker 7.
