Sembcorp Marine (Seatrium) – Phase 2
5 MWp Solar Integration | Mega-Shipyard Grid
Operating one of the largest integrated shipyards in Southeast Asia, Sembcorp Marine (now Seatrium) required a massive renewable energy injection to offset the high consumption of its steel fabrication facilities. This project involved the deployment of a 5 MWp solar system, integrated directly into the shipyard’s active electrical network without disrupting critical marine operations.

The Engineering Challenge
Deploying solar atop an active shipyard presents unique heavy-industry risks. The installation team had to navigate extreme working heights on the curved metal roofs of the massive steel workshops, all while gantry cranes and heavy machinery operated below. The saline marine environment also demanded corrosion-resistant equipment and strict IP65-rated cabling standards.
The Technical Solution
- Distributed Architecture: Utilized Huawei Smart String Inverters to minimize DC cable runs and improve system redundancy.
- Seamless Integration: The system feeds directly into the yard’s internal grid via custom AC Distribution Boards equipped with ABB SACE Tmax Breakers, prioritizing solar consumption for heavy machinery before drawing from the national grid.
- Safety & Access: Custom Cat-ladders and lifeline systems were installed to ensure safe long-term O&M access at 40m elevation.
