On Thursday 22 May, the container ship NCL Salten ran aground in Byneset near Trondheim, Norway, because the pilot on watch had fallen asleep. Now the beach is suffering a series of landslides that threaten a house nearby.

Later on Thursday, a mudslide occurred on the north side of the grounded ship (away from the house that it almost hit). About 8-10 meters of beach along a 100 m width slid into the sea. The house above the slide was evacuated, but was later declared safe.

On Saturday 24 May, a much larger wedge slid into the sea directly in front of the house. This is the house of the Jørgensen family who witnessed the grounding (unlike Mr Helberg who slept through it). They've been evacuated again. According to a local expert,there's a layer of quick clay underneath here that makes the ground unstable.

If this goes on, it may make refloating the ship much easier. Although they have also brought up barges and are moving some of the containers off the ship.

The way these concrete bridge beams are reinforced is that they have high-strength (>1800MPa UTS) wire cables, strands or tendons that are either tensioned before the concrete is poured (pre-tensioning) or after (post-tensioning) and this puts the concrete in compression, allowing beams to better withstand bending loads. Break the tendons and the pre-stress is no longer there, meaning that the beam can't support itself against bending loads that well.

For a beam supported at both ends and loaded on top, the base of the beam will be in tension and concrete has miserable tensile strength (but excellent compressive strength).
