At the end of the Second World War, millions of tonnes of unwanted explosives and weapons were disposed of at sea. For decades, these dumped munitions lay hidden beneath the waves as time and tide passed over them.

Now 80 years past that mass-dumping, corrosion has begun to expose the explosive chemicals inside these weapons casings. Lead, mercury and TNT breakdown products have begun to be detected in fish stocks throughout the affected waters. At the same time, the growth of offshore infrastructure such as wind farms is increasing the need to understand and manage hazards on the seabed.

But dumped munitions are not the same problem as unexploded ordnance (UXO). Instead of finding isolated dangerous objects, engineers face vast areas containing thousands of items, requiring new approaches to detection, removal, containment and disposal. This is a question of new technologies, new approaches, and still yet, convincing people of the scale of the problem.

The post #370 The Forgotten Arsenal of the Ocean: Clearing Dumped Munitions first appeared on Engineering Matters.

In this Engineering Matters Awards episode, we celebrate the winners of the Health & Safety Champion category, which recognises engineers who are changing how we protect people in some of the world’s most challenging environments.

Engineering is often measured by what we build: the bridges, tunnels, infrastructure, and systems that shape our world. But true engineering excellence is also defined by how we build, and how we protect the people who make it possible. This episode explores how innovation, preparation, and predictive technology are helping to reduce risk and improve safety across the board.

Our two award-winning entrants are:

Scott Shipley, Director of Swiftwater and Whitewater Parks at Caliber Engineering, who is transforming emergency response training by creating realistic, controlled environments where first responders can prepare for extreme flooding scenarios.

Monica Calle, co-founder and CTO of Geprode, is using predictive analytics to address one of underground construction’s biggest challenges: geological uncertainty.

The post #369 Health & Safety Champion – Engineering Matters Awards first appeared on Engineering Matters.

This episode is part of the Engineering Matters Awards series, recognising individuals and organisations making an outstanding contribution to the engineering profession and wider society. Engineering is often judged by technical achievements: better products, more efficient processes, and breakthrough innovations. But some of the industry’s most meaningful contributions happen beyond the core aims of the work itself.

The role of engineers in society is to solve problems and create a more liveable world. Through the development of a project or a product an engineer may have the opportunity to bring about a wider community benefit, beyond solving the primary problem. It is those choices that this award recognises.

In this Engineering Matters Awards episode, we celebrate two Bronze-level winners in the Community Champion category: Dremere Woods of Honda Development and Manufacturing of America, and Gaurav Mittal of Thermo Fisher Scientific. Join us as we explore why engineering excellence is not only about solving problems, but also about improving lives.

Guests:

Gaurav Mittal, Data Science Manager, Thermo Fisher Scientific
