In the evolving narrative of maritime decarbonisation, Razor Blunt Labs (RBL) has positioned itself as a key innovator, particularly evident in their role in conceptualising and developing Singapore's first battery-electric ferry service for Shell Eastern Petroleum. This project is a shining example of RBL's commitment to pioneering sustainable and efficient maritime solutions, marking a significant milestone in the industry's journey towards a greener future.

The Shell Bukom Electric Ferry Service: A Case Study in Innovation

The Shell Bukom Electric Ferry Service, a project that involved the creation of a battery-electric ferry service and supporting charging infrastructure, showcases RBL's expertise in digital modelling and simulation. The client, Penguin International Limited, partnered with RBL as a tender partner, entrusting them with the responsibility of developing a comprehensive and innovative solution for Shell Eastern Petroleum's requirement of a greener, less polluting transport option for their refinery workforce.

Technical Prowess and Environmental Responsibility

The technical highlights of the vessels designed for this service are remarkable. Each ferry has a cruise speed of 21 knots and is equipped with an energy capacity of 1.2 MWh, operating on a system voltage of 1100 VDC. The ferries feature both DC and AC charging methods, with charging powers of 2.9MW DC and 250kW AC, and an autonomous charging interface. This level of technical sophistication is a testament to RBL's ability to integrate complex systems into practical and efficient maritime solutions.

Charging Infrastructure: The Backbone of the Service

The charging infrastructure developed for the ferry service is equally impressive. It includes power sources from 3 substations, a step-down from 6.6kV to 550VAC, DC chargers of 3x 2.9MW, and AC chargers of 3x 250kW. The charger control features auto load levelling and charger monitoring both locally and remotely, all within an installation area of 16m2. This infrastructure underscores RBL's capabilities in not only designing vessels but also in creating the necessary supporting systems for their optimal operation.

Environmental Impact and Energy Efficiency

The environmental impact of the Shell Bukom Electric Ferry Service is significant. The ferries operate with zero emissions 100% of the time (not accounting for grid emissions), showcasing an energy efficiency 245% greater compared to conventional vessels. This translates to an annual saving of 1950 tons of fuel and a reduction of 6000 tons of CO2 emissions. The charging energy delivery itself is 97% efficient, further emphasising the project's contribution to sustainable maritime transport.

Razor Blunt Labs: A Leader in Maritime Decarbonisation

RBL's role in the Shell Bukom Electric Ferry Service project highlights their position as a leader in maritime decarbonisation. Their ability to conceptualise, design, and implement complex and efficient solutions, not only in terms of vessel design but also in the necessary infrastructure, sets them apart in the industry. This project is a clear indicator of RBL's commitment to advancing sustainable maritime solutions and their capability to meet the challenging demands of modern maritime transport.

As the industry continues to move towards a more sustainable future, the work of Razor Blunt Labs in projects like the Shell Bukom Electric Ferry Service will remain pivotal. Their innovative approach, technical expertise, and commitment to sustainability are shaping the future of maritime transport, steering it towards a greener, more efficient horizon.
