Marine & Offshore Electrical & Automation (E&I) Company in Johor, Malaysia
MHA AUTOMATION Engineering is a PETRONAS-licensed marine electrical, automation and E&I company headquartered in Masai, Johor — delivering LV/HV electrical works, instrumentation and control for FPSO, FSO, FSU, LNGC, Oil Tanker and OSV vessels, plants and terminals across Malaysia and Singapore.
Electrical works, from switchboard to lightning mast
As a Class B Electrical Contractor registered with the Energy Commission (ST) Malaysia, we take on complete LV and HV electrical scopes for vessels, plants and terminals: switchboards, control panel design and fabrication, UPS and power distribution systems, star-delta motor starters, cable laying and cast-resin jointing, IEC-compliant earthing and lightning protection, fire alarm panels and Ex-proof LED lighting — from design and fabrication through installation and commissioning.
Automation & instrumentation that keeps you compliant
The automation half of our name is earned on board: fire & gas detection, emergency shutdown (ESD), inert gas (IGG) systems, tank gauging and overfill alarms, ballast and tank level monitoring, fuel monitoring, AI temperature monitoring, oily-water separator / 15ppm OMD and PLC programming. These are the systems class societies and charterers scrutinise — we keep them reliable, calibrated and documented, backed by our ISO/IEC 17025 accredited calibration.
Based in Johor, built for the region
Our headquarters in Masai, Johor sits minutes from MMHE shipyard and Johor Port, and about 30 minutes from PETRONAS Pengerang and Tanjung Pelepas Port — with Singapore just across the strait. That geography lets our teams mobilise fast for port calls, dockings and offshore campaigns anywhere in the region, on land or at sea, around the clock.
Since 2014 we have delivered E&I scopes for clients including PETRONAS-linked operators, Malakoff, Petron, MISC and Vale — as a PETRONAS-licensed, 100% Bumiputera, ISO 9001:2015 certified company.
