Dale Marsh - TRENZ GmbH - Germany / New Zealand

The Bremen-based company strengthens its international team with a well-known and experienced Portable Pilot Unit expert.

TRENZ GmbH has appointed Dale Marsh, an experienced Portable Pilot Unit (PPU) specialist, as its International Sales & Marketing Manager, with a focus on the Pacific region and North America. The appointment supports the German company's continued efforts to build out its international presence.

Dale is a familiar name within the global pilot community. For around a decade he has worked with maritime pilots, pilot organisations and port authorities around the world. Based in New Zealand, he has been active across many international markets, with New Zealand and Australia among the largest. His background spans high-precision GNSS positioning, pilot navigation systems and the day-to-day realities of operational pilotage. Over that time he has built close working relationships across the pilot community.

Before joining TRENZ, Dale held senior roles with internationally recognised PPU manufacturers. There he supported pilot organisations in adopting advanced navigation technologies and contributed to the development of the modern Portable Pilot Units now used in demanding pilotage environments around the world.
Frank Diegel, CEO and shareholder of TRENZ GmbH, welcomed the move. "Dale is a well-known figure in the pilotage community, and he has built a lot of trust there over the years. Just as importantly, he has always kept a strong focus on the practical needs of pilots," he said. "His knowledge, international experience and industry relationships will be a real asset as we continue to develop the next generation of pilot navigation solutions."

For Dale, the decision to join the company reflects a shared view of where pilot navigation is heading. "Throughout my career I have had the privilege of working with pilot organisations around the world and seeing first-hand how technology can make pilotage safer and more efficient," he said. "What impressed me most about TRENZ is not only the quality of its engineering, but also its willingness to listen to pilots and to keep improving its products based on real operational experience."

He also pointed to the technological shift now underway in the sector. "The industry is entering a new era. Resilient navigation, protection against GNSS interference, intelligent software and the seamless integration of new technologies are becoming increasingly important. I believe TRENZ is well positioned to help lead that development, and I'm glad to be part of it."

The appointment comes as maritime pilotage faces a changing technological landscape. A rise in GNSS jamming and spoofing incidents, alongside growing expectations for precise, digital pilotage solutions, is increasing demand for more resilient and intelligent Portable Pilot Units.

By adding Dale to its international team, TRENZ says it is further strengthening its expertise and global reach as it continues to work with pilot organisations worldwide on technologies intended to improve safety, situational awareness and operational efficiency during pilotage.
