Rapp Marine Clinches 150-Ton Subsea Crane Deal

By Mark Edward Nero

Deck machinery and winch builder Rapp Marine said that it has agreed on terms with Otto Candies to deliver a 150-ton AHC crane for one of the company’s vessels.

Rapp Marine, which has delivered around 450 cranes throughout its history, said this is the largest crane it has engineered and built to date.

The crane is designed to be capable of lifting 150 tons at 17 meters, and is to be certified by Lloyd’s registry. With active heave compensation and a winch capable of storing 3,100 meters of 77mm wire rope, the crane will be fully outfitted for subsea operation.

“We’re excited for the new challenge presented to us,” Rapp Marine US CEO Johann Sigurjonsson said in a statement. “Our extensive track record in engineering, manufacturing and servicing heavy lift deck machinery and marine cranes equips us to develop an impressive crane for the market.”

The crane was designed by Rapp Marine engineer Helge Stakkeland out of Norway, using techniques and technologies that the company says will increase performance and reduce the crane’s weight.

Rapp Marine says it plans on this crane being the first of many cranes capable of lifting heavy loads for offshore vessels in the Gulf of Mexico and around the world.

Rapp Marine’s US operations, which are headquartered in Seattle, has maintained a working relationship with Louisiana-based Otto Candies for many years, providing electric active heave compensated heavy lift winches as well as service support for several of Otto Candies’ vessels.
