Definition: Inland/ Inshore Commercial Diving
Inland/ inshore commercial diving is defined as occupational diving operations within the territorial waters of Singapore. Examples of territorial waters include docks, harbours, anchorages, canals, reservoirs, lakes, rivers and dams.
Diving Safety and Health
Commercial diving exposes divers to hazards in the underwater environment and many other risks. Some of these hazards and risks include:
- Environment (currents, tides, visibility, marine animals)
- Entanglement/ entrapment (divers’ lifeline and/or umbilical)
- Decompression illness (e.g. barotrauma, nitrogen narcosis)
- Weather (wind, rain, lightning)
Before any diving operation, you should prepare a dive plan covering the following aspects minimally:
- Dive method
- Dive team and the duties of each member
- Diving equipment
- Diving tasks
- Diving procedures
- Diving support locations
- Emergency procedures
- Risk assessment
Commercial Diving Services
When procuring the services of commercial diving contractors, you must ensure that the appointed contractor has the necessary expertise to carry out work safely.
