The role of an underwater welder attracts many people for high payment and an interesting work environment. The work combines the job of commercial diving with welding skills. It’s found in industries that include natural resource exploration and extraction, shipyards, and underwater pipelines, to name a few.
Working underwater as a welder is one of the most risky occupations in the world. So how many underwater elders die a year? Although not fixed, the death rate is far more likely than in other types of welding jobs.
How Many Underwater Welders Die Each Year?
It’s estimated that 15 out of every 1,000 welders will die during the course of their duties every year. Inspenet confirmed a 15% death ratio through the data of Gitnux.
Some organizations have higher estimates, while others are a little lower.
Annual Mortality Rates in the Underwater Welding Industry
The annual mortality rate statistics differ between reporting agencies. Some report an average of six deaths a year. Others report up to 15.
Underwater Welder Death Rate Statistics from Reliable Sources
The death rate of underwater welders varies according to different sources. However, the Inspenet survey brought different mortality rate data associated with underwater welding. It includes:
-
15% mortality rate for underwater welders; a sharp 4X rise from the average death rate in workplaces.
-
Among offshore divers, one in every 1000 dies within 10 years of his job.
-
Subsea welders have an average lifespan of 35 to 40 years; half the lifespan of an average American.
Common Reasons for Underwater Welding Deaths
Many of the causes of death in underwater welding are similar to those of dryland welding. The difference between the two comes down to the environment. Adding to the risks are equipment malfunctions and accidents that increase the risk of death. Here’s a look at the most common reasons for an underwater welding death.
Electrocution
Welding equipment requires electricity to function. Also, water increases the conductivity of an electrical current. A shock from the welding equipment can arc into the body and stop the heart, known as electrocution.
Drowning
Underwater welders wear specially designed suits that have oxygen feeds. Some of the welders might wear specially designed SCUBA gear. Sometimes things go wrong with the equipment due to a lack of preventative maintenance or inattention. When the equipment is defective or not maintained, the welder drowns as a result.
Equipment Malfunctions
The equipment used by an underwater welder is complex. If it’s not properly maintained, a malfunction can happen that results in the welder drowning.
Decompression Accidents
Welders work in deep water ranging from 30 to 500 feet, or even more.
-
Shallow Depths: 10 to 30 feet for maintenance on docks, ships, and bridges.
-
Mid-Depths: 30 to 130 feet for larger repairs on ship hulls and offshore platforms.
-
Deep-Sea Depths: 130 to over 1,000 feet are common in the offshore oil and gas industry.
The deeper the welder goes and the longer they work, it increases the risk of nitrogen bubbles. It happens because of the increased pressure underwater. During ascend, it can block blood circulation and cause decompression.
Being female
Women are at a higher risk of death because they have a harder time tolerating the working conditions.
Having poor cardiovascular health
Poor cardiovascular health is one of the main causes of death among underwater welders because of the extreme conditions. It could come in any form but all can contribute to an early death because of poor circulation. The reasons include:
-
Coronary Artery Disease.
-
Stroke.
-
Hypertension (High Blood Pressure).
-
Heart Failure.
-
Arrhythmia.
Obesity
An obese person lacks agility and may also have poor cardiovascular health. So, obesity increases the risk of suffering a cardiac event, decompression sickness and limited mobility while underwater.
Heart defects
Heart defects impair the circulatory system. It makes the heart work harder in stressful situations. When welders dive deep, the heart might not be able to cope up with the extreme pressure and condition. It causes heart failure and death.
Cold water
Freezing temperatures make it harder for the body to function right. Underwater welders work in extremely low temperatures, averaging 10°C to 30°C and as low as 36°F (2°C). Although welders wear specialized equipment for working in cold water, it still makes their body slow.
Lung disease
Lung damage from chronic conditions results in less oxygen circulation. This also slows down the body and mind during exertion.
Fatigue
Yet another risk factor that makes the body slow to respond in stressful conditions.
Hypothermia
Underwater welders work in low water temperatures. It ranges:
-
Coastal or offshore water temperatures is around 50°F to 85°F (10°C to 30°C).
-
Deep-sea projects could be as cold as 36°F (2°C).
-
Tropical water temperature can exceed 90°F (32°C).
Working for too long in cold water conditions leads to hypothermia. If not caught in time, the welder can suffer from low body temperatures and not recover. In many cases, it leads to their death.
Explosions and Burns
The cause of explosions during underwater welding jobs is the thermolysis (or breaking down by heat) of water. A hot welding arc can reach temperatures of over 10,000°F. It breaks the water molecules to hydrogen and oxygen molecules.
These gases accumulate in the confined area to create a highly explosive mixture. A spark can then cause a devastating explosion and might burn the welder.
Delta P (Differential Pressure)
This happens when a high-pressure body of water comes into contact with a low-pressure body of water. The resulting force can injure or kill the welder.
Animal Attacks
The underwater environment is full of lifeforms that can randomly attack. Wearing diving gear makes it more difficult to avoid such attacks.
Cause | What Happened |
Impairment injury | The diver was injured and unable to save themselves.
|
Trigger event | An event, such as an explosion, triggered the diver’s inability to react quickly.
|
Poor judgment | The diver made an error in judgment due to inexperience or oversight.
|
Panicking | An unexpected result or event caused the diver to panic and make a bad decision.
|
The Injuries Underwater Welders Could Suffer
Hazard | Description | Possible Consequences | Safety Measures |
Electrical shock | Poorly shielded electrical lines | Burns, electrocution, death | Check equipment regularly, discard old equipment, and ensure proper use |
Explosions | Gas from welding equipment ignites | Burns and serious injuries | Make sure to use the proper equipment or work on dry land before installation |
Hypothermia | Spending too much time in cold water | Impaired judgment, slow movements | Use the correct cold water suits and equipment, limit the amount of time spent in the water |
Drowning | Making fatal mistakes while underwater | Death | Check equipment before use to make sure it’s in working order. Replace worn parts on a regular schedule |
Decompression sickness | Rapid ascent introduces nitrogen bubbles into the bloodstream | Pain in the joints, impaired mental function, and death are possible | Return the welders to the surface at a controlled rate. Place them into a decompression chamber immediately |
Risk Factors Contributing to Underwater Welding Deaths:
In the case of underwater welding, the working conditions exacerbate existing risk factors, increasing the odds of dying on the job. They include.
Age and Physical Fitness
A diver’s physical condition increases their risk of a premature death. Being in poor physical health makes it harder to perform underwater and tolerate the environment.
The Impact of Poor Cardiovascular Health
Water pressure makes it harder for the heart to work. If someone has poor heart health, they’ll struggle to work underwater. The heart can stop under these conditions.
Effects of Obesity and Heart Defects
A welder with one or both of these issues can’t perform well. Their body are more susceptible to injury.
Special Laws and Regulations That Protect Underwater Welders:
The underwater welding field is protected by rules that affect everything from working hours to equipment and more.
Occupational Safety and Health Administration (OSHA) Guidelines
OSHA is a federal agency that makes sure all US workplaces follow safety guidelines. It provides precise guidance for the underwater welding industry to ensure all welders are working in a safe environment.
Maritime Safety Laws and Protections
These laws and protections are applied when a welder is working away from the shore. They’re enforceable when the employee is working on a ship, platform, or other seafaring vessel. Depending on their working agreement, they can claim compensation under:
-
The Longshore and Harbor Workers' Compensation Act (LHWCA) for their medical care, lost wage and vocational rehabilitation.
-
maintenance and cure allows them to receive daily expenses until the injured welder is fit to rejoin his profession.
Regulations on Diving and Welding Equipment
The regulatory bodies that oversee the industry are also in charge of setting the manufacturing standards for equipment. All diving and welding equipment has to meet these standards before being approved for use.
