Maersk Tankers’ digital spin-off is beginning its formal operation on Thursday with hundreds of vessels already using its software to reduce bunker consumption.

In a press statement, ZeroNorth said it already has more than 300 vessels from six customers running the Optimise software that was formerly known as SimBunker.

Targeting the tanker and bulker sectors, the digital tool is designed to find each ship’s optimal speed based on prevailing freight rates, bunker prices, weather and individual vessel performance.
