Hydraulic and controls specialists for the energy sector
Someone on the project should own the hydraulics.
On large projects the hydraulic scope often sits outside the project team until a package fails its test or a vendor variation arrives. EHM puts a hydraulic and controls specialist on your side from specification to handover, then commissions the packages and supplies the people to finish the job.

Services
Specialist support from the first specification to the last punch item.
EHM is more than a manpower supplier. We manage hydraulic scope, commission the packages ourselves and inspect what is already installed.
Project management
Hydraulic packages are bought from vendors and then judged by a project team that rarely includes a hydraulic specialist. Problems are found late, and variations are hard to challenge. We sit in or alongside your PMT and own that scope technically.
