Pintsch Bubenzer puts a brake on semi-submersible

FLEMINGTON, NJ: September 04, 2019. Pintsch Bubenzer, a manufacturer of a variety of high performance disc and drum brakes, has installed a series of Twin Safe TS800 brakes on two 10,000-tonne capacity cranes and auxiliary hoists aboard a giant semi-submersible crane vessel that has recently completed its maiden voyage.

The Sleipnir, named after Norse god Odin’s eight-legged horse and part of Heerema Marine Contractors’ fleet, is self-propelled with a minimum service speed of 10 knots.

The dual-fuel engined heavy-lift and deep-water construction vessel is over 700 ft. long and is designed to work on large offshore projects such as installing and removing jackets, topsides, deep-water foundations, moorings and windmills.

Rated for 8,000Nm to provide a 35 percent boost in torque, it took six months to develop the brake based on customer requirements – which centered on a need for a high torque solution to mount onto a smaller than typical motor flange.

Mike Sparks, regional sales manager at Pintsch Bubenzer USA said: “All industries are trying to get larger to be more cost-effective and we need to align our manufacturing capability and technologies with that trend. The port industry continues to grow and the reason that this vessel was created was due to larger rig platforms being designed. The cranes were also made large to increase the amount of deck space available on the vessel since they are able to conduct the work that is usually done by three or more cranes.”
