Rethinking offshore logistics: 24/7 HEMS unlocking efficiency image

How hybrid logistics and real-time operational insights are transforming offshore wind access.

As offshore wind projects grow in scale, distance and complexity, the industry’s logistics demands are evolving just as rapidly. Traditionally, service operation vessels (SOVs) have been the backbone of offshore access, offering accommodation, storage and stable transfer capabilities. However, these customized vessels come with a significant price tag, limited flexibility and long lead times for procurement. In today’s US market, where agility, safety and cost-efficiency become even more paramount, a hybrid model is gaining traction: the integration of crew transfer vessels (CTVs) with 24/7 helicopter support and helicopter emergency medical services (HEMS) support.

This approach isn’t just a supplement to traditional operations, it’s a shift in optimizing efficiency. By using existing assets and optimizing logistics through a modular design, developers can now achieve SOV levels of availability and even better rates at a fraction of the cost. And more critically, developers gain the ability to operate around the clock, even when sea states would traditionally shut down operations.

These shutdowns can sometimes last seven to 10 days or more, a regular occurrence in the US North Atlantic or North Sea.
