diving equipment
Equipment used for a dive, including wetsuits and drysuits, helmets, scuba equipment and any umbilical equipment which provides the connection with the surface.
Construction commercial divers work below the surface of the water to install equipment, such as hydraulic structures, waterways and marine facilities. They also inspect, remove and repair the structures.

Essential skills and competences 16 competences
Occupation specific
4 competencescope with decompression
Ascend from a dive in stages or slowly according to a decompression plan in order to give the body time to adapt to the lowered pressure. Prevent the buildup of dissolved gases in living tissue, as well as other symptoms linked to rapid ascent, collectively known as decompression sickness or "the bends".
use lift bags
Use bags filled with air to help carry objects underwater, or send them to the surface. Choose the right capacity lift bag for the object to be carried and attach it securely to the object. If multiple bags are used, make sure the lifting capacity is distributed evenly.
weld in hyperbaric conditions
Use arc welding techniques to make welds in conditions of very high pressure, usually in an underwater dry chamber such as a diving bell. Compensate for the negative consequences of high pressure on a weld, such as the shorter and less steady welding arc.
weld underwater
Use underwater arc welding equipment to make welds beneath the water surface. Protect yourself from electric shocks by shielding the weld from the water.

5 competencescheck diving equipment
Check diving equipment for valid certification to ensure its suitability. Ensure that any diving equipment is examined by a competent person before use, at least once on each day on which it is to be used. Ensure that it is adequately tested and repaired.
comply with the planned time for the depth of the dive
Ensure that a diver returns from a given depth after the planned time limit has expired.
implement dive plans
Implement dive plans, working with the client, vessel teams and marine superintendents.
interrupt diving operations when necessary
Terminate or interrupt the diving operation if you judge that continuing the operation is likely to endanger the health or safety of any person involved.
use rigging equipment
Set up rolling and lifting equipment required to lift and move objects e.g. with a crane or block and tackle system.

digital
mechatronics
Multidisciplinary field of engineering that combines principles of electrical engineering, telecommunications engineering, control engineering, computer engineering, and mechanical engineering in the design of products and manufacturing processes. The combination of these areas of engineering allows for the design and development of "smart" devices and the achievement of an optimal balance between mechanical structure and control.
robotics
The branch of engineering that involves the design, operation, manufacture, and application of robots. Robotics is part of mechanical engineering, electrical engineering, and computer science and overlaps with mechatronics and automation engineering.

Work from various types of underwater chambers such as bells, wet bells and underwater habitats. Distinguish the properties of the chamber and keep yourself and others in the chamber safe.
Sector-specific
17 competencesdisplay warnings around dive site
Ensure that warning devices are displayed in the area around a dive site, so as to keep it clear of any equipment other than that associated with the diving operation.
dive with scuba equipment
Use scuba equipment to dive without air supply from the surface.
ensure diving operations conform with plan
Ensure that the dive adheres to the operational plan and the contingency plan.
ensure health and safety of dive teams
Monitor the safety of the dive teams. Ensure that the operation is carried out from a safe, suitable location as per diving operation manual. When necessary, decide whether it is safe to proceed with the dive.
