Lem Technologies designs and manufactures control panels for all concrete plants sold by BMH Systems for over 30 years. One of our major projects for them has been the control panels for two modular concrete batch plants for the construction of the drilling platforms of the Hebron project located offshore Newfoundland and Labrador, in Canada.
Located offshore Newfoundland and Labrador, the drilling platforms were developed using a stand-alone concrete gravity-based structure (GBS). Totally made of high-strength concrete, the concrete had to be poured with a slip form system. A modularized construction was needed to facilitate the relocation of the twin batch plants to the barge to allow the oil platform to be completed offshore.
BMH provided two modular concrete batch plants used to produce the concrete for the construction of the GBS. BMH Systems supplied a twin central mix batch plant mounted on a barge, with two 5,4 yd³ twin shaft mixers, 935 tons of aggregate storage and 1,800 tons of cement storage. This turnkey project also included an automation system capable of batching in the harsh environment of the ocean with very strict tolerances that had to be able to withstand the worst possible storms.
Lem Technologies’ tasks and responsibilities
- Design and build control panels
- Design and implement security components to meet the safety standards required by the application and BMH needs
- Design wiring in a container for the electrical control and distribution room of each concrete plant
- Design a system to quickly disconnect and reconnect the electrical cables for the motors and controls on each modular concrete batch plants safely and without error, since the modular concrete batch plants began manufacturing concrete on dry land and done the balance in a deep water bay
- Electrical installation as per Canadian electrical standards in each container
- FAT in our plant before shipping
