Introduction

The HKK 32, a state-of-the-art hybrid catamaran, is gearing up to transform the commuter experience across Hong Kong's bustling waterways. This vessel is part of a groundbreaking nine-ship order initiated by the Hong Kong Government in its quest to cut emissions and embrace eco-friendly maritime transport.

Hybrid Drive System

Equipped with a cutting-edge hybrid drive system and an AYK Energy lithium-ion energy storage unit with a capacity of 414 kWh, the HKK 32 can operate in zero-emissions mode during slow-speed travel, berthing, and other maneuvers. This significantly reduces its carbon footprint, showcasing its commitment to sustainable operations. Moreover, the ferry features advanced exhaust treatment technology and is complemented by approximately 30 square meters (around 300 square feet) of solar panels, which enhances its onboard power sustainability.

Specifications and Capacity

With impressive dimensions—an overall length of 39.8 meters (131 feet), a beam of 10.5 meters (34.4 feet), and a maximum draught of 2.1 meters (6.9 feet)—the HKK 32 can accommodate 450 passengers alongside a crew of five. Two robust Cummins QSK 50-M1 engines, each generating 1,529 kW (2,050 hp) at 1,800 rpm, propel the vessel using Danfoss electric motors, enabling it to reach a remarkable top speed of 25 knots and a cruise speed of 23 knots.

Passenger Comfort and Amenities

Passenger comfort is paramount, with the main deck capable of holding 300 passengers, while an additional 150 can be accommodated on the upper deck. The vessel is also designed with a variety of amenities, including bicycle racks, restrooms, and a 10-square-meter (110-square-foot) cargo hold on the main deck, as well as extra luggage storage on the upper deck. For operational needs, it possesses a generous tank capacity of 6,600 liters (1,500 gallons) for fuel oil, alongside 1,000 liters (200 gallons) each for fresh water and sullage.

Demonstrator Vessel and Future Developments

The HKK 32 is more than just a commuter ferry; it serves as a demonstrator vessel that will assess the viability of low-emission technologies for future vessels. Powering its onboard systems is a Perkins Stamford generator rated at 120ekW, ensuring reliability and efficiency throughout its service.

Upcoming Innovations

In a notable upcoming development, HKKF will soon welcome another vessel from the same series. However, this iteration will feature an aluminum hull instead of the HKK 32's fiberglass-reinforced plastic (FRP) construction. The operational performance and sustainability metrics of both the FRP and aluminum-hulled vessels will be systematically studied over the coming years to guide future innovations.

Conclusion

The HKK 32 is set to sail under the Chinese flag and has received classification from Bureau Veritas, guaranteeing its adherence to high standards of safety and efficiency. As Hong Kong moves toward a cleaner and more sustainable future, the HKK 32 is leading the charge in transforming public transport on the water. Don’t miss your chance to witness the dawn of a greener era in maritime travel!
