Hughes Hunter - Diving Daughter Craft
Hughes Hunter - Diving Daughter Craft
The dive craft is supported during offshore operations by support craft for supply and personnel transport. It is ideally suited for restricted area access around offshore vessels/platforms and MoDu where DSVs have limited access for maintenance/surveys. It is also ideal for harbour inspection and repair workscopes where access from the quayside is restricted.
Typical wokscopes:
- Marine structure inspecton (ACFM, MPI, CP, etc.)
- Light construction works
- Debris removal
- Special periodic surveys (SPS) carried out to class requirements
- Inshore harbour construction / survey work
- Offshore renewables
- Vessel inspection / survey
- UXO ID and removal
- Subsea construction
- IMR inspection, repair and maintenance
- Salvage / decommissioning
- FPSO / FSO diving support
