Conquering Harsh Offshore Environments for Indonesia’s Marine Energy Sector

We are proud to announce the successful delivery of two sets of high-specification 1600kVA marine oil-immersed transformers specifically engineered for an FPSO (Floating Production Storage and Offloading) unit operating in Indonesia.

Offshore oil and gas extraction demands absolute stability and safety from its power supply systems. Facing the severe challenges of high temperatures, extreme humidity, heavy salt spray, and constant hull vibrations, our engineering team utilized decades of technical expertise to complete the entire process—from custom design and manufacturing to stringent certification—within a tight 4-month lead time. This project stands as another powerful testament to our specialized capabilities in the global high-end marine electrical equipment market.

• Project Location: Indonesia
• Application: Onboard marine power supply system for FPSO
• Product Name: 1600kVA Marine Oil Immersed Transformer
• Quantity: 2 Sets
• Compliance Standard: IEC60076 (International Electrotechnical Commission)
• Lead Time: 4 Months

As a “floating offshore factory,” an FPSO requires onboard equipment to possess exceptional anti-vibration, anti-corrosion, and explosion-proof properties. To ensure these two 1600kVA transformers operate safely and reliably over the long term in Indonesian waters, we implemented full-scale, deep structural customizations:

The equipment was designed and rigorously tested in absolute accordance with IEC60076 standards, ensuring that all electrical performance metrics reach world-class levels. Furthermore, to satisfy the stringent legal and regulatory frameworks governing offshore assets, this batch of transformers successfully passed rigorous inspections and obtained full Classification Society Certificates, serving as a trusted passport for safe offshore deployment.

Considering the continuous swaying, rolling, pitching, and severe mechanical vibrations present in an FPSO engine room, the internal body of the transformer was heavily reinforced. All internal components, fasteners, tank structures, and lead wire supports feature specialized anti-loosening and mechanical locking designs to withstand the extreme tilt angles and cyclic fatigue common to marine vessels.

The marine environment in Indonesia is characterized by tropical heat, high humidity, and intensive salt fog. To counter this, the transformer tanks were treated with a C5-M grade marine heavy-duty anti-corrosion coating system to block salt spray and moisture penetration. Additionally, the fully sealed oil-immersed design isolates the internal dielectric fluid from the atmosphere, significantly slowing down oil aging and achieving virtually maintenance-free operation.

Space inside a ship’s engine room is always at a premium. By optimizing the electromagnetic core design and rearranging the cooling radiator layouts, we successfully packed a robust 1600kVA capacity into a highly compact physical footprint. This optimization minimized both overall weight and dimensions, perfectly adapting to the strict space constraints onboard the FPSO.

For offshore megaprojects, project delays translate directly into massive operational losses. Upon receiving the urgent request from our client in Indonesia, we immediately fast-tracked the project through our specialized manufacturing workflow:

• Rapid Synchronization: Engineering teams finalized the blueprint designs and pre-approved the documents with the classification society within weeks.
• Efficient Manufacturing: Our supply chain, production workshops, and testing centers worked in perfect sync to implement modular, high-precision assembly.
• Rigorous Testing: Before leaving the factory, both transformers underwent full factory acceptance testing (FAT) and type tests witnessed live by classification society surveyors at our advanced Testing Center.

Ultimately, we achieved full compliance and delivered the units within the promised 4-month timeline, ensuring the equipment was shipped to Indonesia exactly on schedule.

The successful delivery of the Indonesia FPSO 1600kVA Marine Oil Immersed Transformers marks another major milestone in our high-power marine equipment portfolio. It further solidifies our strategic presence in the Southeast Asian marine engineering sector. We remain committed to delivering “high standards, top quality, and maximum efficiency” to provide safer, more dependable industrial and marine power solutions worldwide.
