VESSEL REVIEW | Voltai – Electric supply boat to be operated in Singapore's port waters

Reducing lightering fleet requirements

The vessel also incorporates several technologies that KMG said are aimed at enhancing efficiency. The hull design reduces power consumption by as much as 10 per cent at 10 knots under full load, and the vessel makes use of a digital twin.

Voltai will be operated in Singapore’s port and regional waters, serving merchant vessels at anchorage. Its daily operations will include what PaxOcean termed as consolidated “milk run” deliveries, and this will be made possible with an open cargo deck designed for efficient handling of high-capacity loads.

“With four times the payload capacity, Voltai potentially replaces two to three conventional supply boats,” PaxOcean told Baird Maritime.

For PaxOcean, one challenge in designing the new supply boat was related to achieving zero-emission capability while meeting demanding operational requirements.
