The document is a brochure from ABB describing its electric propulsion system for large-size LNG Carriers. The system is composed of dual fuel engines and electric propulsion systems, and it provides fuel flexibility and high efficiency.
The brochure introduces ABB's Dual Fuel Electric Propulsion (DFEP) technology for large‑size LNG carriers, describing how electric propulsion delivers lower fuel consumption, reduced installed power, and full fuel flexibility. It outlines the core components – dual‑fuel four‑stroke engines and electric propulsion motors – and shows typical single‑ and twin‑screw carrier configurations.
ABB also details its Marine Services program, offering preventive maintenance planning, on‑call support, training and the eMST electronic maintenance tool to ensure long‑term equipment availability for LNG vessels.
| Power plant voltage (single‑screw example) | 6.6 kV |
|---|---|
| Power plant voltage (twin‑screw example) | 6 kV |
| Electric motor power (example) | 1000 kW |
Electric propulsion provides lower fuel consumption across the speed range, reduced installed power, full fuel flexibility, enhanced maneuverability, and high reliability through redundancy.
