Recycle.

Reuse.

Titan Salvage is doing both.

The majority of the New Carissa’s stern will be hauled off to a recycling facility. But at least one piece, affectionately known as “Billy’s Box,” will go back in the water. Named after the Karlissa B’s crane operator and diver Billy Stender, the former water storage container will serve as a “coffer dam” — a buffer for divers as they work in the crashing waves to salvage a crane head that fell from the wrecked ship.

Working in the surf off the North Spit will be hazardous to divers. Sheltered by the box, divers with cutting torches will be able to maintain level cuts.

Titan’s divers may have a bigger task on their hands if salvaging of the main wreckage doesn’t go as planned. The plan is to whittle the New Carissa down to the waterline, then gradually lift and slice the submerged portions.

Titan has an arsenal of six 300-ton “pullers” to lift the submerged wreckage above the waves, but divers will be the last resort if the lower part of the New Carissa stays put.

“If we can’t pull it out, then we will have divers go down and cut it off,” Managing Director David Parrot said.
