In the latest episode of The Wayfinder Podcast, Sofar's Thomas Hechmann sits down with Peter Søbygge, who leads fleet operations at Uni-Tankers, a Danish company founded in 1995 and part of the USTC group, which owns and operates more than 40 ships.

Peter walks through why operational efficiency isn't one KPI to chase, but a constant series of trade-offs between vessel speed optimization, fuel, weather, laycan windows, and commercial commitments, often made and remade within the same voyage. He explains how Unitankers relies on maritime weather routing and voyage optimization software like Wayfinder to support these decisions without replacing the judgment of the people making them.

The conversation covers where inefficiency hides in tanker operations, why a single weather delay can turn into a lost contract, and how the weather impact on shipping costs shapes voyage planning day to day. It also gets into how EU ETS and FuelEU, part of the broader push toward shipping emissions reduction, are adding new layers of complexity to voyage calculations.
