Born and raised in Brabant (very close to Efteling), Emile spent around 18 highly adventurous and educational years as part of the military system. Qualified to operate in extended various disciplines and shaped by the rigorous “green” Methodology, he developed a keen ability to respond inventively and ad hoc to incidents under Spartan conditions, a skillset still tested in practice somewhere on the globe today.
Since 2018, he has combined this discipline with SOLAS, STCW, and hands-on maritime expertise, delivered with a touch of humor, sharing his knowledge during training sessions under the motto: “Train as you fight.” He mainly works at the DRTC site in Flushing, on-site at companies, and on board vessels (an honorary privilege!), though he started out at the Groningen-site.
As a hobbyist in MARCOM, he contributes to DRTC’s consistently strong performance (≥90%) on CBR exam results.
Key traits: No-nonsense, energetic.
Born and raised in Zeeland, Michel de Pooter carries the sea in his heart. From a young age, his parents took him along on their sailing boat, instilling in him a deep-rooted love for the water and maritime life.
After completing his Maritime Officer training, Michel began his career as a 4th Officer with the cruise ships of Holland America Line. In the following years, he rose through the ranks to Staff Captain, gaining a wealth of experience in leadership and ship operations on board cruise vessels worldwide.
In 2025, Michel chose a new course: a shore-based position that allowed him to spend more time with his family while sharing his extensive hands-on knowledge with others. As Senior Maritime Instructor at DRTC, he delivers a variety of maritime training programs and is also regularly involved in the preparation and development of courses at the office.
Maarten Janse was born and raised in Zeeland and has a deep connection with the sea. After completing his Bachelor of Maritime Officer degree at the Maritime Institute De Ruyter (2002–2006), he began his career as a 4th officer on the cruise ships of Holland America Line. In the years that followed, he progressed to 1st officer and gained worldwide experience in ship navigation and maneuvering, delivering safety training to crew in various emergency roles, organizing emergency drills, and leading teams responsible for the maintenance of lifesaving appliances and fire detection, prevention, and firefighting systems.
In 2022, Maarten made the transition to a shore-based position, wishing to spend more time with his family while sharing his extensive hands-on experience with others. As a Senior Maritime Instructor at DRTC, he delivers training such as AFF, PST, PSCRB, FRB, ECDIS, GWO, and MCRM, as well as modules within ship management. His trainings are realistic, practice-oriented, and always linked to real-world situations. Maarten holds the certificate of competency as Master Mariner (all ships) and Firefighting Crew Member, and is a certified CAE MCRM instructor, making him a specialist in maritime incident response and teamwork.
Maarten has a strong passion for sharing knowledge. As a black belt holder in Kyokushin karate, he enthusiastically taught both youth and adults for many years. That same energy, dedication and attention to the participant characterize his approach in every training he delivers.
DRTC provides a wide range of accredited safety courses for the maritime, offshore, wind and industrial sectors.
