To supply a special purpose hoist of 100 tonne lifting capacity with a headroom of less than one metre was the task recently faced by the J D Neuhaus design team

J D Neuhaus delivered initial drawings to customer within one week and three dimension drawings with final layout of lifting gear after only a further two and a half weeks The design for the UH 100 hoist covered an air driven monorail unit, with two hoists used in tandem to provide handling for a 200 tonne BOP (blow out prevention) system for lowering a cap on to the wellhead of an offshore drilling rig

With headroom space at a premium, Neuhaus was able to exceed specifications by achieving an ultra low headroom of only 700mm for the units.

In addition, It was also able to meet production deadlines with delivery made to site in the USA earlier this year.

The hoists were designated for the 'jack-up' rig Chiles Discovery under construction at the Amfels shipyard in Brownsville, Texas.

This rig will operate in the Gulf of Mexico in maximum water depths of 110m.

Meanwhile, Chiles Offshore has subsequently placed an order for a second hoist system for use with its drilling rig number 5, with a delivery planned for October this year.

The air driven hoists manufactured by J D Neuhaus are particularly suitable for the environments encounted with oil exploration, where electric powered units pose potential hazards.

The company has also supplied several 250 tonne systems built specifically for Rowan's Gorilla class jack-up rigs.
