Coastal Sustainability Alliance Signs LOIs, Showcases Electric Boat

SINGAPORE, 26 MARCH 2025 – The Coastal Sustainability Alliance (CSA), an industry collaborative effort led by Kuok Maritime Group (KMG), today signed two Letters of Intent (LOIs) on Day 2 of the Accelerating Digitalisation and Decarbonisation Conference at Singapore Maritime Week (SMW) 2025. The first focused on prioritising using PXO’s E-Supply Boat by key ship agencies during an upcoming trial, and the second focused on developing a multi-modal, multi-site marine charging infrastructure. These partnerships mark a significant milestone in advancing the adoption of e-vessels and supporting infrastructure, setting the stage for the fruition of CSA’s vision to develop Singapore’s next-generation coastal logistics ecosystem.

“As one of the world’s busiest ports, Singapore experiences a high volume of activity daily that relies heavily on supply vessels. At Horizon Shipping Agencies (S) Pte Ltd, we prioritise sustainability, and supporting the adoption of electric supply vessels is a vital step forward. This transition not only enhances operational efficiency but also significantly reduces emissions, contributing to a cleaner, greener future for the maritime industry.” says Horizon Shipping Agencies Operations Manager, Raymond Tan.

“Milk Run” Trial with Shipping Companies for E-Supply Boat Adoption

The trial addresses the growing pressure on merchant shipowners to reduce Scope 3 emissions, offering a commercially viable pathway for greener supply chain solutions. Each E-Supply Boat trip is expected to cut 0.5 metric tons of Scope 3 greenhouse gas (GHG) emissions per arrival of a merchant ship at the Port of Singapore. As the marine logistics industry pivots towards net-zero goals, the electrification pathway can result in an estimated reduction of 9,000 metric tons of GHG emissions per month across 600 daily trips made by conventional supply boats. The findings from the trial will influence the development of future PXO E-Supply Boats, ensuring that they align with industry needs while advancing Singapore’s decarbonisation goals.

Public Visit to Singapore’s Largest Electric Supply Boat

SMW 2025 will feature an exclusive public showcase of the PXO E-Supply Boat Voltai, Singapore’s largest electric supply boat and one of the first to be accorded Maritime and Port Authority of Singapore’s (MPA) Tier 1 design for next-generation electric harbour craft.Recently delivered from PaxOcean Batam, this vessel has four times the cargo space of conventional supply boats and represents a significant step forward in sustainable maritime logistics and decarbonisation efforts. Visitors can explore the Voltai’s groundbreaking features, including its expanded cargo capacity, zero-emission propulsion system, and advanced energy storage system. The tour will highlight how the vessel’s battery energy storage system enables zero-emission operations and covers an 80-nautical-mile range at 8 knots while reducing operational costs and carbon footprint.
