Dock gate hydraulics

The company, based in Middlesbrough, UK delivers major hydraulic engineering projects across the world and successfully won this project following its work on the Boston Barrier supporting BMMJV (a joint operating venture of BAM Nuttall and Mott MacDonald).

IMH has already supplied a main hydraulic power unit and two emergency hydraulic power units to power the Boston tidal flood barrier which weighs around 730 tonnes when in operation.

This phase of the project will see IMH deliver a single main hydraulic power unit (MHPU) which will power both the North and South wet dock entrance gates, as well as two emergency hydraulic power units (EHPU) which are diesel driven.

Interconnecting pipework and control cables will be routed under the wet dock entrance structures with each wet dock entrance gate actuated by a single hydraulic cylinder. The new wet dock entrance gates will be operated by the hydraulic control system.
