Parbuckling and the Costa Concordia

16_FIL0121

For those interested…I sure am there is a live streaming of the attempt to right the Costa Concordia. It seems to be going well at the moment.

The official website of the project is fascinating.

The technique used is called parbuckling.

Parbuckle salvage, or parbuckling, is the righting of a sunken vessel by applying leverage to rotate the vessel into an upright position from one where it is either on its side or fully inverted. A common operation with smaller watercraft, parbuckling has been used successfully to right large vessels. USS Oklahoma (BB-37) was rotated nearly 180 degrees to upright after being sunk in the attack on Pearl HarborTH, and the MS Costa Concordia is being parbuckled off the west coast of Italy. 

A major concern during salvage is to prevent the rotational torque from becoming a transverse force moving the ship sideways. USS Utah (BB-31), lost like the Oklahoma in the Pearl Harbor attack, was meant to be recovered by a similar rotation after the Oklahoma. As the Utah was rotated, however, its hull did not catch on the harbor bottom, and the vessel slid towards Ford Island. The Utah recovery effort was abandoned.

I love big engineering projects, they are fascinating and amazing. I can’t wait to see the inevitable National Geographic doco about it all.

As much at home writing editorials as being the subject of them, Cam has won awards, including the Canon Media Award for his work on the Len Brown/Bevan Chuang story. When he’s not creating the news, he tends to be in it, with protagonists using the courts, media and social media to deliver financial as well as death threats.

They say that news is something that someone, somewhere, wants kept quiet. Cam Slater doesn’t do quiet and, as a result, he is a polarising, controversial but highly effective journalist who takes no prisoners.

He is fearless in his pursuit of a story.

Love him or loathe him, you can’t ignore him.
