Key Responsibilities

• Install, inspect, clean, or repair piping or valves.
• Recover objects by placing rigging around sunken objects, hooking rigging to crane lines, and operating winches, derricks, or cranes to raise objects.

• Perform activities related to underwater search and rescue, salvage, recovery, or cleanup operations.
• Supervise or train other divers, including hobby divers.
• Salvage wrecked ships or their cargo, using pneumatic power velocity and hydraulic tools and explosive charges, when necessary.
• Carry out non-destructive testing, such as tests for cracks on the legs of oil rigs at sea.
• Descend into water with the aid of diver helpers, using scuba gear or diving suits.
• Inspect and test docks, ships, buoyage systems, plant intakes or outflows, or underwater pipelines, cables, or sewers, using closed circuit television, still photography, and testing equipment.

• Communicate with workers on the surface while underwater, using signal lines or telephones.
• Cut and weld steel, using underwater welding equipment, jigs, and supports.
• Operate underwater video, sonar, recording, or related equipment to investigate underwater structures or marine life.
• Set or guide placement of pilings or sandbags to provide support for structures, such as docks, bridges, cofferdams, or platforms.
• Repair ships, bridge foundations, or other structures below the water line, using caulk, bolts, and hand tools.
• Take test samples or photographs to assess the condition of vessels or structures.
• Inspect the condition of underwater steel or wood structures.
• Remove obstructions from strainers or marine railway or launching ways, using pneumatic or power hand tools.
• Take appropriate safety precautions, such as monitoring dive lengths and depths and registering with authorities before diving expeditions begin.
