Heavy-Lift Derrick Barge Can Lift Up To 400 Tons

An innovative and versatile system using Lucker hydraulic pulling machines to operate a crane, to pull or tension as required, has been incorporated into the derrick barge Mr. "2" Hooks (shown in drawing above), recently outfitted by i t s owner, Portable Marine Structures, Inc.

of Houston.

The heavy-lift barge was designed for medium offshore and heavy inshore work, at a reasonable daily cost. It features a 400-ton sheerleg derrick utilizing twin load lines. Also on the barge is a 150-ton auxiliary revolving crawler crane for general lifting and rigging requirements.

The barge will meet the demand for a unitized barge outfitted for heavy lift, pull or tensioning operations in marine salvage, demolition and marine construction.

The 180-foot-long raked bow and square stern barge has a beam of 70 feet and a depth of 12 feet. It has crew quarters and a four-point mooring system.

Each of the load lines operates independently, each utilizing a 150-ton hydraulic machine. This is an important advantage in compensating for uneven loads and reducing common sling and equalizing problems. Jibs and rigging can be attached to the 110- foot-long sheerleg to increase the crane's reach for other special jobs.
