During the two-week Underwater Field Training Exercise, trainees have the opportunity to gain hands-on experience on practical aspects of what they have learnt in classroom, including:
- Application of baseline and offsets method,
- Application of Ties method to baseline for leveled profile bars,
- Site datum for vertical depth gauge measurements,
- GPS points in Site Recorder,
- Using photo scales for all underwater photographs,
- Seabed elevation/ profiles survey using depth gauge and site datum,
- Centerline / baseline elevation survey using depth gauge survey and site datum,
- Port and starboard hull elevations using depth gauge survey and site datum,
- Port and starboard hull lines using depth gauge/ site datum and vertical offsets,
- Taking sections / profiles across wreck using leveled profile bars
- Drawing using planning frame,
- Measuring and recording iron ship construction details (frames and spacing, rivets, plating, stem and sternpost dimensions),
- Circular searches,
- (For novice divers) familiarization with diving and underwater work: how to use tape measures and underwater drawing boards as their diving skills developed,
- Most importantly, learning how to work in team.
