Driving Decarbonization in Maritime
Together with Sea Forrest and Taiyo Electric , BOS Marine is committed to supporting the maritime sector’s transition toward decarbonization. We focus on reducing greenhouse gas emissions while enhancing vessel efficiency, reliability, and compliance with evolving environmental regulations.
By combining technical expertise and a shared vision for a greener future, we aim to lead the transformation of maritime operations through practical, scalable, and sustainable solutions. Our expertise covers Marine Electric Propulsion Systems, Hybrid Power configurations, and Energy Storage solutions.
Our Power Solutions
We offer a range of comprehensive power solutions tailored for diverse marine and offshore applications.
Full Electric Propulsion
Electric motor-driven systems offering zero-emissions operation. Ideal for harbour crafts, ferries, and other vessels requiring clean, quiet power.
Full Electric-Ready Propulsion (Serial Hybrid)
Electric motor-driven with an onboard generator (Serial Hybrid) to improve efficiency and reduce emissions. Suitable for harbour tugs, supply boats, bunker tankers, and more.
Green Hybrid Propulsion (Parallel Hybrid)
Combines electric motors and diesel engines (Parallel Hybrid) to significantly reduce fuel consumption and emissions. Perfect for pilot boats, fast crew boats, CTVs, and patrol crafts.
Energy Saving Systems (Green Cabin®)
Our Green Cabin® system offers peak-shaving and energy storage functions, available for both retrofits and new builds. Suitable for fast crew boats, ferries, tankers, and cargo ships.
Energy Storage
SeaGen® Marinized Battery
SeaGen® is Singapore’s first marinized lithium-ion battery system, fully designed, assembled, and type- approved for marine propulsion. Its flexible, modular design allows easy installation and configuration of battery modules to meet different voltage requirements, making it ideal for various marine platforms and confined spaces.
Marine & Offshore Energy Storage System: Energy Cube®
The Energy Cube® is a versatile, high-performance peak-shaving and backup power solution designed specifically for marine and offshore applications. It seamlessly integrates into vessel and platform power systems, whether onboard or onshore. Available in 1.8 MW and 2.2 MW configurations, it adapts to a wide range of power requirements. Perfect for deployment across diverse platforms including oil rigs, offshore platforms, FPSOs, AHTSs, PSVs, SOVs, CSVs, accommodation work barges, containerships, tankers, bulk carriers, and car carriers, the Energy Cube® ensures smooth integration, optimized performance, and reliable operation.

Showcasing our commitment to sustainable maritime solutions through successful implementations.
February 2021: Singapore’s First Hybrid Electric Propulsion Vessel “Penguin Tenaga”
(15m Crew Transfer Vessel)
Equipped with a 46.0 kWh PMSR electric propulsion motor and a 42.6 kWh lithium-ion battery (LIB), Penguin Tenaga achieves a speed of 5 knots in full-electric mode. When switched to hybrid operation (electric motor + diesel engine), it reaches a top speed of 24 knots.
