With Concordia finally in dock, Italian marine contractor Micoperi reports that the Saab Seaeye Falcon ROV played a vital role in diver safety during the largest maritime salvage operation in history. Fabio Bartolotti of Micoperi, the contractor responsible for the project, said that the Falcon worked every day of the salvage operation, spending more than 1,000 hours in the water. He noted that every single time a diver entered the water the Falcon was deployed in their support and for their safety.

Lifting Costa Concordia

The successful Costa Concordia Parbuckling project

The largest and most complex maritime salvage operation ever carried out was concluded this summer. The Costa Concordia parbuckling operation on the rocks of the Italian island of Giglio has been a success in many ways—not least for the objective to retrieve in one piece, such a massive vessel (117,000 tons) with minimal damage to the delicate marine environment on which it foundered. High performance ropes with Dyneema played a key role in the operation. DSM Dyneema has been supplying UHMWPE fiber, branded as Dyneema  for ropes used in tug and salvage operations for almost 15 years.

Dyneema: Making Light Work of Ultra-Deep Sea Recovery Operation

Dyneema Salvage Operation

A salvage operation on a ship wreck 3200 meters below the surface of the South Atlantic has been successfully carried out thanks to the use of lightweight ropes made with Dyneema ultra-high molecular weight polyethylene fiber. Dyneema fiber, the world’s strongest fiber, is manufactured by DSM Dyneema. It is used by Hampidjan, one of the largest fishing gear and “super rope” manufacturers in the world, to make Dynex Warp, an advanced patent-pending winch line for deep sea lifting and lowering as well as for towing fishing trawls.

The Central Queensland Port Authority is undertaking one of the largest capital improvement projects in Australia. The RG Tanna Wharf Expansion Project involves extending the pier by 350 meters, widening existing berths, building a 1.3 kilometer onshore conveyor, and creating a new jetty approach. The cost of the construction portion alone is $128m. Marine contractor Realf’s Diving and Salvage was hired to survey the area before the dredging operation could begin. The company is based in Gladstone…

A Helping Hand in Stralsund

The Stralsund ship lift reportedly breaks all records, as nowhere in the world is there a lifting and lowering facility on a larger scale than this 754 x 115 ft. (230 m x 35 m) lift. Equally impressive is its power, which enables it to raise and lower a ship of up to 20,700 tons to a maximum of 36 ft. (11 m) without difficulty, the Maersk Valencia in December 1999, serving as an example. The bow of the oceangoing giant peers out of the 36 ft. (75 m) high shipyard bay, its steel hull follows: the Maersk Valencia, a 682 ft. (208 m) containership, edges slowly forward. On 432 wheels, a strange vehicle trundles along the rails like a steel centipede, at two meters a minute.

JHRG Releases New Chafe-Protective Devices

JHRG has released a new weapon in the battle to protect commercial marine rope from chafe. Featured in Sail Magazine (May 2002), JHRG patent-applied-for chafe-protective devices are made from Supreme Protector fabric and thread. Made with 80 lb. Test SPT 138 thread and 1,000lb./inch fabric, both pre-curved and straight tubes protect eyes, ropes, hoses and lines in a broad range of amarine applications from military and pleasure craft to oceangoing tugboats and cruise ships. Supreme Protector materials resist cuts, moisture, abrasion, UV and common shipboard contaminants. The same materials are employed in awnings, FAA-certified air cargo restraints, airline luggage cart curtains and U.S. Coast Guard/ U.S. Navy boat and gun covers.

Loose Cable Contributed To Crane Collapse

The collapse of a giant, brand new gantry crane which killed 36 people in a Shanghai shipyard may have been caused by loose steel ropes, state media and an engineer at the crane's designer said. Chinese authorities are investigating the accident, the latest in a series of deadly fires, explosions and building collapses that highlight China's lax safety standards and have roused public anger. The collapsed crane is one of the largest gantry cranes to be built and designed in China, capable of carrying 600 tons, engineers and shipbuilding executives say. It was only inaugurated on Monday. The H-shaped structure weighed a total of 4,900 tons and consisted of two legs and a 3,000-ton crossbeam, an engineer at a Chinese company which designed the crane said.
