Водолаз на строительных работах — работа в Финляндии
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.
Водолаз на строительных работах - Какие навыки обязательны?
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.
Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.
The operational plan and the contingency plan for the diving operation, the diving equipment to be used in the diving operation, the diving signals to be used in the diving operation, the in-water decompression procedures to be used in the diving operation, and any emergency procedures that might have to be used in the diving operation.
Check construction supplies for damage, moisture, loss or other problems before using the material.
Ensure that a diver returns from a given depth after the planned time limit has expired.
Set up rolling and lifting equipment required to lift and move objects e.g. with a crane or block and tackle system.
Apply the relevant health and safety procedures in construction in order to prevent accidents, pollution and other risks.
Ensure that diving operations comply with legal requirements.
Perform maintenance actions, including small repairs, on diving equipment.
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.
Use underwater arc welding equipment to make welds beneath the water surface. Protect yourself from electric shocks by shielding the weld from the water.
Use elements of protective clothing such as steel-tipped shoes, and gear such as protective goggles, in order to minimise risk of accidents in construction and to mitigate any injury if an accident does occur.
Maintain records of the progress of the work including time, defects, malfunctions, etc.
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.
Equipment used for a dive, including wetsuits and drysuits, helmets, scuba equipment and any umbilical equipment which provides the connection with the surface.
Implement dive plans, working with the client, vessel teams and marine superintendents.
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".
Terminate or interrupt the diving operation if continuing the operation is likely to endanger the health or safety of any person involved.

Conduct regular inspections during and after the construction of offshore facilities such as oil platforms to ensure risk minimisation and compliance with regulations.
Assess the dive with the dive team upon completion. Instruct the diver(s) so as to improve procedures and routines for future dives.
Walk flow lines to identify damage or leaks; use electronic detection equipment and conduct visual inspections.
Transport explosives and safely load explosives into drill holes.
Wade through a body of water to inspect the piles of a bridge. Put on the appropriate equipment, such as weights, and make sure to have an associate present for safety reasons.
Work as part of a team in a construction project. Communicate efficiently, sharing information with team members and reporting to supervisors. Follow instructions and adapt to changes in a flexible manner.
Manage explosives in accordance with explosives law, including tracking and control of the magazine.
Operate equipment to pump the sewage sludge and store it into containers in order to transform the gases it emits into energy. After this phase, dry the sludge and evaluate its potential reuse as fertilizer. Dispose of the sludge if it contains hazardous elements.
Use spanners to adjust machinery and equipment.
Visually inspect a concrete structure to see if it is structurally sound. Check for different types of cracks, such as those due to reinforcement corrosion, impact damage or high water content.
Safely install gas pipes and tubes made of steel or copper. Install all necessary connectors and modern ball valves. Test the pipe to make sure there are no leaks.
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.
Prepare the construction pit and guide the pipeline used to place the concrete mix underwater in a process called tremie. Ensure a continuous flow of concrete to avoid water going up the pipeline.
Use scuba equipment to dive without air supply from the surface.
File and organise personal administration documents comprehensively.
Receive incoming construction supplies, handle the transaction and enter the supplies into any internal administration system.
Operate cutting and measuring instruments in order to cut/shape pieces of metal into given dimensions.
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.
Recognise the symptoms of metal showing oxidation reactions with the environment resulting in rusting, copper pitting, stress cracking, and others, and estimate the rate of corrosion.
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.
Ensure that the dive adheres to the operational plan and the contingency plan.
Thoroughly examine explosion areas; determine the appropriate amount of explosives required; ensure compliance to safety regulations.
Operate a range of drilling equipment, pneumatic as well as electrical and mechanical. Tend drilling equipment, monitor and operate it, according to regulations. Safely and efficiently drill holes using the correct equipment, settings, and drill bits.
The characteristics, functioning and way of working with dynamic positioning systems, construction barges and dive support vessels.
Use a hand drill to make holes in various types of material such as stone, brick and wood. Take care to use the appropriate equipment, settings, drill bit and pressure for the task.
Conduct maintenance and repair work on pipelines to prevent or remedy damages using, if necessary, remote-controlled robots.
