Tag Archives: Container Ship

By Vladimir Brezina

Johna’s recent post about Keith Tantlinger, the inventor of the Twistlock, the device  that has made modern container shipping possible, reminded me of the question that I always have when I see a loaded container ship in the harbor. How securely do all those containers, stacked so high on top of each other, remain stacked when the ship rolls and pitches in heavy weather? (Indeed, how stable is the ship itself when loaded so high, although that’s a different question.) Perhaps suggested by another of Johna’s posts, the image of falling dominoes comes to mind, or perhaps a house of cards…

Well, now there’s an answer.

The Twistlock locking corners that anchor each container to the container below, and to the container above, hold up surprisingly well. In this photo of the Rena, the container ship that grounded a week ago on Astrolabe Reef off the northern coast of New Zealand, entire stacks of containers so anchored lean at a 45-degree angle without collapsing…

But, inevitably, some containers are falling into the sea and washing up on local beaches. Here, “local residents come to look at a washed up container with its cargo of packets of partly-cooked hamburgers littering the beach…”  (Usually, locals do more than just look…) Unfortunately, not just hamburgers, but large amounts of oil are now also washing up on the beach, and there is no end in sight.
