Best practices for shipboard welding

Seafaring comes with its own set of challenges and risks. Accidents affect the health and wellbeing of crew, damage vessels and equipment, and cost a lot of money. This is why safety on board matters.

There are many factors to maintaining maritime safety. To start, a clean environment is a must. Ship inspection must be thorough, accurate, and professional. There must be systems in place to safeguard the mental health and wellbeing of crew. Similarly, repairs and maintenance work through welding and cutting—key activities that keep vessels seaworthy—must be conducted safely, too.

Fostering a culture of safety and health in the workplace is a collective effort that requires consistency, inclusion, and working together to find appropriate, sustainable, and effective ways to keep the workplace safe.

In maritime welding, safety should be top-of-mind

Welding can be unsafe when tools are worn down due to continuous use, are unmaintained, and are non-compliant with regulations. Procedures may be inefficient or inconsistent.

Crew members who do not have the appropriate training and competency levels or skills may not carry out shipboard welding safely. It pays to ensure that all maritime fitters have the necessary welding skills and competencies, and that these are continuously refreshed or reviewed.

When not conducted safely, welding can cause three serious consequences:

  • Increase the risk of accidents, resulting in injuries and fatalities onboard
  • Damage to welding equipment or other critical/high-value equipment
  • Result in inefficient repairs and maintenance.


But conducting welding safety checks can be tricky

For seafarers, making sure that welding will be done safely at all times can be difficult. For one, it can be time-consuming without a streamlined process. Busy ship operators and crew members may have a hard time completing all the tasks required to keep welding equipment in good condition.

Moreover, there are a lot of safety protocols, and keeping track of them can be tedious.

Finally, ensuring equipment and processes comply with regulations adds another layer of complexity.

How to get welding safety right

There are some ways to get welding safety right off the bat.

Firstly, you should procure good tools and equipment. You can do so by using welding machines designed specifically for the maritime industry, and purchase from reputable suppliers who have proven safety track records in the maritime industry like Wilhelmsen Ships Service’s UNITOR brand. Finally, pick and standardize tools across various ports and workplaces.

Next, empower your crew by providing training for how to use the welding equipment properly, efficiently, and safely.

To maintain safety standards, conduct welding safety checks regularly and document everything.
