Jorian Schut was born and raised in Bergen op Zoom, where he grew up surrounded by water. Through sea scouts and sailing he discovered his passion for the sea and adventure. After completing his Maritime Officer studies at HZ University of Applied Sciences in Vlissingen (2016–2020), he started his seafaring career in early 2021 as an officer on heavy lift vessels. For four years he sailed worldwide and gained extensive experience with ice navigation in the Arctic region.
In early 2024, Jorian decided to pursue a shore-based career. Having previously attended his own safety courses at DRTC, he returned with great memories of that time – this time as an Maritime instructor. Since then, he has been delivering nearly the full range of STCW training, simulation training and GWO programs at DRTC. In addition, he is actively involved in the development of new courses, ensuring the training offer remains relevant and of high quality.
His training style is hands-on, approachable and always focused on learning together. Jorian values the stories and experiences of participants, creating an environment where everyone learns from one another. For him, safety courses should never feel like a mandatory exercise, but rather like a meaningful and enjoyable experience.
With certifications such as Firefighting Crew Member (and currently training for Firefighting Commander) and practical experience in challenging maritime environments, Jorian has built a solid foundation. Looking ahead, his ambition is to further expand his role by delivering more courses, developing new programs and taking on greater leadership responsibilities within the organization.
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.
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.
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.
Bas Gloudemans has been active in maritime safety training for many years. What began as a hobby—diving during HUET training—has grown into a passion for the maritime industry. After starting his career as an instructor and completing training as a safety specialist, Bas held various management positions at different training providers.
In addition to his dedication to safety training, the development of training centers both in the Netherlands and abroad has played a central role throughout his career. With experience from the Middle East, Asia, and Europe, Bas ultimately settled in what may well be considered the cradle of maritime education and training in the Netherlands: beautiful Zeeland.
Alongside his directorial responsibilities, Bas is still occasionally active as an instructor. After all, old habits die hard…
