If necessary, set-up will be completed on 27 April or when staff join Alba na Mara during the morning of 28 April. ROV trials will start in the Moray Firth in areas of sandy sea-bed and 30 m depth with the vessel at anchor. Subsequent instrumentation and TV trials will continue as conditions permit. The stability of the ship's mains supply will be monitored while under different load. The ship will return to Fraserburgh at the end of each day for equipment configuration and to review data. During the second half of the survey, the vessel will sail to Orkney or Loch Erribol to calibrate the EK60 system and hull transducers. After the trials, Alba na Mara will un-load equipment in Fraserburgh on 5 May.
