The sun, earth and moon….

What did God have to do with it? Blamed on wind, the Ever Given cargo ship stuck in the Suez Canal. So the moon came to the rescue. He created all this stuff and we  joyously take advantage of His grace.

To get the giant container ship blocking the Suez Canal unstuck, engineers needed the stars to align. Actually, the sun, Earth and moon. 

After several days trying to dislodge the Ever Given cargo ship, which had veered off course and embedded itself in the side of the canal, the salvage team pinned their hopes on this week’s full moon, when, beginning Sunday, water levels were set to rise a foot-and-a- half higher than normal high tides. That would make it easier to pull the 1,300-foot vessel out from the side of the canal without unloading a large number of the 18,000 or so containers it was carrying. 

The engineers would have to work fast to make the most of this narrow window. The effect would last only a few days. But it would be their best shot at freeing up the canal— and with it, billions of dollars’ worth of global trade flows in the process. 

Tides are higher when there is a full or new moon, which occurs when the moon is in direct alignment with the sun, with either the Earth or moon in the middle of the three. This causes a greater gravitational pull on the Earth. As a result, high tides are higher, and low tides are lower. They are known as spring tides and occur twice a month. 

This time the effect was amplified by the first supermoon of the year, when a full moon coincides with the closest point to Earth in its elliptical orbit. 

Supermoons occur several times a year, and this one is known as the worm moon, for the earthworms that begin to appear in the soil in the Northern Hemisphere at this time of year. 

When it became clear that tugboats alone wouldn’t be able to dislodge the Ever Given, the rescue effort began looking to the supermoon’s pull on the tides and how it might help free the vessel. 

According to people involved in the operation, much of the work to dredge hundreds of thousands of cubic feet of sand was undertaken with the higher water levels in mind. Dredgers were assigned to the area and worked around the clock. 

Lars Mikael Jensen, head of A.P. Moller-Maersk A/S’s global ocean network, said Monday was a particularly important day, when water levels began to peak. “In the last couple of days all the available tug power has been allocated,” he said. Higher tides could give the salvage team the lift it needed to refloat the Ever Given.
