TRAnsverse tugs demonstrate how they can expand the operating envelope and reduce fuel consumption during ship escort and manoeuvring
As editor of International Tug & Salvage, I have had the opportunity to see firsthand the advances in tug design, engine technology and propulsion development.
In a recent interview, Svitzer chief operating officer Kasper Karlsen shared with ITS the forward-leaning initiatives the Danish owner is taking in terms of alternative fuels, electrification and tug design.
This includes operating its first TRAnsverse tugs, Svitzer Taurus in Amsterdam, the Netherlands, and Svitzer Barrington and Svitzer Nobbys in Newcastle, Australia.
Two of these TRAnsverse tugs are operating side by side, providing a significant uplift in towage and shiphandling capabilities in demanding operations within the second-busiest port in Australia.
Svitzer Barrington and Svitzer Nobbys were built by Uzmar Shipyard in Turkey to a TRAnsverse 3200 design, which was jointly developed by Svitzer and Robert Allan Ltd.
“The TRAnsverse represents a generational step forward in tug design,” said Mr Karlsen. “It is not just about more power, but is about smarter, safer and more efficient operations.”
TRAnsverse design tugs can undertake dynamic operations including side-stepping speeds of up to 8 knots and lateral push, all while maintaining stability and control.
“The innovation of this tug lies in how it can adapt safely and responsively to pilot orders, for a variety of manoeuvres, in different and often difficult operating sea states and weather,” said Mr Karlsen.
By operating these three tugboats in two ports, Svitzer has demonstrated how the TRAnsverse design has expanded the operating envelope by up to 50% compared with conventional tugs, while improving fuel efficiency by up to 15%.
“The outcome and priority underpinning everything, of course, is to help our customers navigate the world’s largest vessels safely, reliably and sustainably – and to keep trade moving,” said Mr Karlsen.
Svitzer has produced a short documentary to complement its technical paper on TRAnsverse tugs, detailing the indepth research and development, testing and trial process that underpin TRAnsverse tug performance in operations.
These illustrate how Svitzer continues to move towage forward safely, efficiently, and responsibly. More details will be presented to the towage industry at Riviera’s ITS Convention in Gothenburg, Sweden, in May 2026. The Mega Machines video is available on Svitzer’s Global YouTube channel alongside the full white paper.
The 28th International Tug & Salvage Convention, Exhibition & Awards will be held in Gothenburg, Sweden, in association with Caterpillar, 19-21 May 2026. Use this link for more details of this industry event and the associated social and networking opportunities.
