Why adapt shallow water geometric compliant moorings with a midwater float

Even though the Sargassum fish lives in the middle of the sea, it spends a lot of time crawling around. This is possible because its habitat is the tangled morass of Sargassum seaweed that floats in large patches in the ocean. These fish are highly adapted to live in this

Why shallow water mooring design takes longer than expected (especially compared to deep water)

IKEA makes furniture. Not a little bit, either. They’ve been the world’s largest furniture retailer since 2008. What do you think their best-selling item is? At over 1 billion units sold, it’s head and shoulders above anything else they make. Here’s a hint: you eat it. That’s right: their best

How to avoid wuzzles when recovering oceanographic moorings

It was Christmas time, but I didn’t expect to get a haircut as a present. On this particular holiday, one of my young son’s presents was a small automatic flying drone. It was a seemingly harmless small toy that merely hovers and slowly drifts around indoors automatically, without the need

What to keep an eye on during oceanographic mooring deployment

The longest continuously running experiment started in 1930 and is still going right now. The Pitch Drop Experiment looks like an hourglass filled with a thick, black substance called pitch. Pitch is a resin that is so thick it looks and acts like a solid. It is so much like

How the anchor-last oceanographic mooring deployment process works

The first time I started running for exercise, it was a disaster. It was a disaster because there are pitfalls that aren’t obvious to people who are new to running. My problem was I just jumped right in without a detailed plan. I had a general idea that I needed

Why an RAO is the dynamic fingerprint of a hull

The Great Blue Hole in Belize looks mysterious from above. It stands out as a perfect dark blue circle – almost black – amid a shallow water atoll. It’s such a dark blue because it is a marine sinkhole. In other words, it’s a large cavern that expands over 100m

How seakeeping analysis reveals surprising differences about ship seaworthiness

Grocery stores are places of scientific discovery. It’s true: biologists wanted to know just what was in a package of store-bought dried mushrooms. Taking an extremely close look, they sequenced the DNA of each mushroom and were stunned at what they found. They were mushrooms all right – but what

What the playground can teach us about resonance in dynamics

Kids are always happy to visit a playground. When my son turned three, the swings became one of his favourites. He always wanted to go higher and higher. At that age, he hadn’t quite figured out how to swing by himself yet, though, and needed a push to keep going.

When wave steepness pinpoints worst case sea states for mooring design (and not wave height)

Vintage wind-up toys may seem simple, but they are mechanical marvels. Many intricate details turn a compressed spring into something like a walking robot. But while these designs are clever, they have their limits. For example, nothing stops them from tumbling off the edge of a table or down the
