As waves strike the hull, they are partly reflected, partly diffracted, and partly transmitted around the vessel itself, creating a “shadow zone” on the leeward side of the hull where wave heights are reduced. At least in theory. But does that really hold true in the real world? And if so, just how much reduction in significant wave height are we talking about?

It sounds hard to know and difficult to measure. Well, not really—it’s all about equipping the vessel with the right type of wave measurement sensors, and the right number of them. At Miros – Real-time Ocean Insights, we’re lucky to have a few clients who wanted to find those exact answers.

Let’s start off by looking at some recent measurements in a low Hs sea state, taken from a subsea construction vessel in the North Sea.
