Custom hydraulic power units, electric power units, VFD panels and integrated PLC / HMI control rooms — built to exceed class requirements and fully load tested before sailaway.
Power & control is the spine of every Dimension equipment package. We engineer and build the complete chain — hydraulic power units (HPU), electric power units (EPU), variable-frequency drive (VFD) panels, motor control centres (MCC) and the PLC / HMI control room that ties them together. Every skid and panel is built to exceed the structural, electrical and class requirements of MODU/SOLAS, IEC 60092 and the project's notation society, and is load tested at FAT against the actual equipment it will drive before being shipped.
VFD drives · HPU skids · PLC · HMI · Integrated Control Room — BV-witnessed
Engineering, fabrication, FAT and offshore commissioning — all under one roof.
