The vessel is equipped with a fully integrated hybrid electrical system delivered by us — from battery pack and propulsion motors to alarm and navigation systems. ## A Complete System. One Responsible Partner. This project is a strong example of what single-source delivery means in practice within marine electrical and propulsion. Frydenbø Elmarin held full responsibility for the vessel's entire electrical system — from initial design through to final installation and handover. For the shipyard and owner, this means fewer interfaces between suppliers, better system integration, and reduced risk of delays or technical discrepancies between deliveries. ## Technical Specifications Frydenbø Elmarin's scope of delivery for the 20-metre hybrid service vessel: - **Battery pack:** 1,575 kWh - **Electric propulsion motors:** 2 × 375 kW - **Thrusters:** 2 × 200 kW - **Main switchboards and control system** - **Alarm system** - **Full electrical installation** - **NAV-COM equipment** All systems are fully integrated and delivered as one complete solution, simplifying day-to-day operations, maintenance, and future servicing for the operator.   ## About the Vessel and the Project The service vessel was built at **Sletta Verft** and commissioned for **Trident Aqua Services**. It is designed for operations within aquaculture — a sector where operational reliability and energy efficiency are critical requirements. The hybrid system allows the operator to run on battery power in environmentally sensitive areas near fish farms, reducing noise and local emissions where it matters most. This is an increasingly important factor in Norwegian aquaculture, where biological considerations and regulatory requirements place clear restrictions on vessel operations. ![Image (4)-2](https://www.frydenbo-maritime.no/hs-fs/hubfs/Image%20(4)-2.jpg?width=1000&height=750&name=Image%20(4)-2.jpg)   ## Why Choose Frydenbø Elmarin as Your Single-Source Supplier? For shipyards, ship owners, and naval architects, having one supplier accountable for the entire electrical system is a competitive advantage in itself. It means: - **Fewer coordination points** between subcontractors - **End-to-end system understanding** from design to completed installation - **A single point of accountability** for service and follow-up after handover - **Shorter communication lines** and faster problem resolution throughout the project Frydenbø Elmarin combines deep technical expertise with the capacity to take full responsibility for large and complex deliveries — backed by Frydenbø Group's industrial heritage since 1916.   ## Planning a Newbuild or Conversion to Hybrid or Electric Systems? Frydenbø Elmarin takes responsibility for the complete electrical system — from concept and design through to final installation and handover. **Get in touch to discuss your project.** Petter Sørensen Head of Green Propulsion Tlf: +47 400 28 650 E-post: pso@frydenbo.no ### Related articles [See all](https://www.frydenbo-maritime.no/artikler) [![What Is Electrical Marine Propulsion for Service Vessels?](https://www.frydenbo-maritime.no/hubfs/Elmarin/B%C3%A5ter/BN%20193%20Multi%20norh.png) ### What Is Electrical Marine Propulsion for Service Vessels? Service vessels operating in aquaculture, offshore support, and coastal industries face growing pressure to cut emissions while maintaining reliable performance. Electrical marine propulsion offers a practical path forward, combining reduced fuel consumption with lower environmental impact.
