Boskalis Int. – Tema Harbour, Ghana
Harbour deepening involving blasting and dredging.
Setting up the site for survey, blasting and dredging. This involved setting up a G.P.S. system, tidal system, survey boat and office. Set up local grid so blasting and dredging could work on the same co-ordinate system due to the failure of the grid presented by the client. Set out points for blasting rig to position itself. Monitored the bulking after each blast.
