Meet Our Trainer: A chat with one of SubConnect’s subsea cable experts – Dave Dunk
At SubConnect, our trainers don’t just teach subsea cable skills — they bring decades of real-world experience, passion, and commitment to excellence. Every subsea cable training course is designed to combine technical precision with hands-on learning, ensuring every trainee leaves confident, capable, and inspired.
When did you become a trainer?
I first became a trainer with Global Marine Group back in 1999. After a short break away from the business, I returned in 2008 — and I’ve been training students ever since. So all in all, I’ve been sharing knowledge and developing future subsea specialists for more than 18 years as part of Global Marine Group and SubConnect.
What did you do before becoming a trainer?
Before I moved into training, I spent over a decade at sea working as a cable jointer — from 1989 to 1999 — gaining hands-on experience in subsea cable repair and installation. I also worked on the London Underground before a brief career change as a Police Officer in 2005. In 2008, I returned to Global Marine, I love the unique work we do, the people and the industry.
What does a typical day look like as a subsea cable jointer trainer at SubConnect?
One of the best things about this job is that no two days are the same. Every course and every group of students bring something different.
On an initial course, I might start by preparing a cable joint in front of the class, then guide the students as they replicate each step, offering feedback and advice along the way. Other days, I’ll be working on qualification moulding, development projects, or supporting hands-on assessments.
Of course, we also make time for a bit of friendly competition in our lunchtime sporting activities — balance is important!
What do you think makes a great trainer?
A great trainer doesn’t just teach — they listen. I’ve learned a lot from my students over the years; everyone brings their own experience and perspective.
I always try to create a relaxed, enjoyable atmosphere as I think this helps people to learn better, and having a sense of humour and a laugh along the way is important too. But above all, knowing your subject inside out and being able to adapt to each learner’s needs is key.
What do you love about training people on UJ/UQJ processes?
It’s incredibly rewarding to see students put their training into practice. When they send me photos from offshore of their first successful joint, it’s a proud moment. And it’s even better when I see them 10 years later, still thriving in their careers — that’s when you know the training really made an impact.
What’s the most valuable lesson you hope trainees take away from your courses?
Beyond mastering the technical skills, I want people to enjoy what they do. An old colleague once said, “Fill your boots, because all you’ll have left is memories.” That’s stuck with me — it’s a reminder to take pride and pleasure in every moment of both your career and personal life.
Is there a particular course or moment that stands out in your training career?
There have been so many great courses over the years — what makes them memorable is always the people. The energy and camaraderie that builds up over several weeks of training are what I enjoy most.
What do you enjoy most about working at Global Marine Group and SubConnect?
Global really does feel like a family. Even though it’s a large organisation, it has that close-knit atmosphere where everyone supports one another. The subsea cable industry itself is fascinating — it’s fast-moving, technically demanding, and constantly evolving. And the people here make it even better.
Finally, tell us a bit about yourself — what do you enjoy outside of work?
Outside of work, I’m passionate about rowing — both ocean and coastal — and I love taking part in triathlons and general fitness activities. I’ll admit I have a midlife crisis Subaru sports car which is good fun! I’m also planning to spend more time hiking around Scotland during semi-retirement, and cycling from Land’s End to John O’Groats is definitely on my bucket list.
Remember, always be happy. It’s better.
