Firm completes major unmanned surveyÂ
A PORTCHESTER firm that makes unmanned vessels has completed a 10,649km survey off the coast of Alaska.Â
ASV Global, working with TerraSond, announced the completion of the hydrographic survey last week.  The 10,649km survey was carried out by an ASV Global C-Worker 5 unmanned vessel alongside the Q105 survey ship acting as the mother vessel.Â
Larry Karl, general manager of ASV Global, said: '˜The C-Worker 5 once again proved itself to be a reliable unmanned vessel for survey with line following precision and excellent sea-keeping ability.'Â
Andrew Orthmann, from TerraSond, said: '˜It allowed us to reduce risk to our personnel while still obtaining the seafloor data important to our client.'Â
ASV Global is based in Murrills Estate, Portchester. Â
