When it is sensible to use nonlinear Froude-Krylov forcing

There’s nothing about tanks that makes them look like they’re ready to fly. At the best of times, tanks are squat and stocky, mean-looking machines meant for slowly crawling over the worst terrain the ground has to offer. In World War 2, tanks were a critical element. Getting tanks to

Why parts libraries are essential to save time in mooring design

After a disastrous World War 2 naval battle, a lone allied warship was left surrounded behind enemy lines. Vastly outnumbered and outgunned, the situation seemed very grim. Still, the crew came up with a plan to sneak back home: disguise the warship as an island. The crew gathered as much

When to avoid a static solver in oceanographic moorings

It was when the traffic light turned green, and my car lurched forward from a stop when it happened. A warning light flickered on the dash, but then quickly turned off again. Fortunately for me, it wasn’t a sign of disaster with the engine – it was just a light

How to effectively model oceanographic surface buoy dynamics

Flying sheep may help you get to sleep, but they can save your life, too. In 1934, the Italian army had a huge logistics problem: crossing one of the most inhospitable deserts in the world. Resupply for the trip was vital, and the army had to consider their options carefully.

How to systematically evaluate oceanographic mooring compliance

People that live in northeastern India use tangled foliage to speed their way through the jungle. But it takes a lot of patience. They can do this with certain kinds of plants, like the rubber tree. As you might expect from a rubber tree, the roots are quite flexible as

How to control uncertainty in buoy drag coefficient when designing oceanographic moorings

It was the summer of 1991 and I stood in front of the first hedge maze I’d ever seen before. What could be more fun to a young boy that getting lost in a hedge maze and finding your way out? I had a simple plan: get totally lost as

Why uncertainty in buoy drag coefficient puts oceanographic data quality at risk

In World Wars 1 and 2, Allied ships were at significant risk to U-boat torpedo attacks. These U-boat torpedo attacks were sinking thousands of vessels. To protect their fleet, the allies desperately needed new ideas and technologies. One concept was called dazzle camouflage. It consisted of wild stripes, colours, and

Why compliance is at the heart of resilient oceanographic surface mooring design

Deep in the Andes Mountains, straddling jagged peaks, sits the 15th century Inca citadel Machu Picchu. It’s a harsh and remote location. To add to this, the ancient site sits on top of fault lines that are prone to earthquakes. But these earthquakes were no match for Incan engineering and

How to control uncertainty in water current profile when designing oceanographic moorings

When you get something different than you expect, it’s a sign that uncertainty has reared its head “Just make sure that it’s good!” It was the last thing I heard from my wife as I bolted out the front door. On a twilight dash to the supermarket down the road,

What the History of Flight Can Teach Marine Renewable Energy

Whether it’s 1903 and you’re the Wright brothers, or it’s 2018, and you’re a technology developer third-party verification provides an opportunity for you to benefit from the experience of those who have gone before.
