Shipping giant A.P. Moller – Maersk (Maersk) on Friday (5 June) said a new milestone in its marine fuel trials, with its dual-fuel feeder vessel Laura Maersk successfully operating on 100% ethanol for a second time. The latest trial marked a significant step forward from earlier tests, as the vessel was supplied through a larger-scale bunkering operation conducted by barge in Rotterdam. “The bunkering, which took place in Rotterdam, involved larger‑scale delivery by barge, allowing us to test operational handling, supply chains and procedures closer to real‑world conditions than in earlier, smaller‑scale trials,” it said. The company said ethanol is one of several pathways being explored as it works to diversify its low‑emission portfolio. “With a growing dual‑fuel fleet, we continue to learn and to build flexibility and optionality by testing different solutions,” Maersk added.   Photo credit: A.P.
