Living Blue With Big Blue Diving Khao Lak

For divers who live and breathe the ocean lifestyle – spending days at sea, diving pristine reefs, and naturally wanting to protect the incredible marine world we’re passionate about.

The Ocean Lifestyle

Four days straight on the water. Multiple dives daily. Sleeping under stars. Waking up to pristine dive sites.

This is living blue.

Diver underwater in the Similan Islands

When you spend this much time in the ocean — really in it, not just passing through — something changes. The reef stops being a backdrop and starts being a place you know. You recognise the turtles. You notice when something’s missing. You start caring in a way that doesn’t feel like effort.

We’re Big Blue Diving Khao Lak. We’ve been running liveaboards and day trips in the Similan and Surin Islands for over twenty years. We love diving and we love teaching people to dive. But Living Blue is something else — it’s what happens when that love of the ocean turns into a genuine commitment to protect it.

Living Blue

No greenwashing. No corporate conservation speak. Just a small team doing real things that matter, in the water we call home.

Our Living Blue Projects (So Far)

Sea Turtle Conservation & Research

This is the one we’re most proud of.

In partnership with Andaman Turtle Watch — the Andaman Sea’s first public sea turtle photo-identification programme — Big Blue has become the single largest contributor of citizen science turtle data in the region. Not the largest liveaboard operator. Not the most well-funded. Just the most committed.

#1 individual citizen scientist 42 sightings, 16 turtles named, 25 unique individuals recorded

We also launched the Andaman Sea’s first dedicated turtle conservation liveaboards — two expeditions with 42 divers, combining our normal dive standards with sea turtle ecology workshops, photo-ID training, and hands-on citizen science.

More planned for 2026–2027.

Our Resident Marine Biologist Eve Pilmore, founder of Andaman Turtle Watch, works closely with Big Blue as our lead conservation scientist. Andaman Turtle Watch is an open programme — multiple dive centres contribute, and we’re proud to be its leading partner without making it exclusive. Good science needs more eyes in the water, not fewer.

New for the 2026–27 season, we’ve developed an exclusive range of SSI Turtle Ecology courses and conservation packages that you won’t find anywhere else. Created around the work of Andaman Turtle Watch, they blend internationally recognised SSI certification with real research, real citizen science, and real conservation happening in the Andaman Sea today.

Teaching the Next Generation

One of Living Blue’s core beliefs is that conservation starts with education.

We love teaching people to dive. We’ve always believed that a great dive instructor doesn’t just teach skills — they pass on a lifelong relationship with the ocean. Every diver we certify becomes someone who understands the reef, respects it, and is more likely to protect it.

This season, we took that idea much further.

Working alongside World Volunteering, we designed and delivered a bespoke ocean education programme for more than 150 international students — combining marine biology, sea turtle conservation, and the SSI Snorkel Diver programme. A further 50 students completed scuba diving certifications alongside their Turtle Ecology training, developing not only new skills but a deeper understanding of the marine ecosystems they were exploring.
Built from the ground up by Big Blue, our Resident Marine Biologist Eve Pilmore, and the World Volunteering team, the programme exceeded expectations from day one. Its success has already led to an expanded return — more than 200 students are due to join us in November next season alone, which tells you everything about the demand for meaningful, conservation-led ocean education.
Our ocean education goes beyond scuba diving. It’s about painting a bigger picture — helping students understand why our oceans matter before giving them the chance to explore them. Every programme is tailored to the group: their age, interests, curriculum, and learning objectives. Sessions can combine snorkelling, scuba diving, Turtle Ecology certification, visits to local conservation projects, hands-on marine science, and time with working conservation practitioners.
This is Living Blue at its most complete: professional dive training, marine biology education, and conservation awareness — all delivered together to the people who are going to inherit the ocean.
We’ll soon be publishing example itineraries and education packages, but we’d always rather build something specifically for your students than ask them to fit into a standard schedule.

Looking After Our Own

Living Blue isn’t just about the ocean. It’s about doing things properly — and that includes how we treat the people who make our operation work.

In the Thai dive industry, it’s common practice for migrant Burmese workers to fill tanks, manage equipment, and handle gas blending — jobs they do brilliantly, often for years, without any formal certification. The existing gas blender qualification is complex, technically demanding, and practically impossible to access for most of these workers. The result is a quiet but serious problem: skilled, experienced people doing safety-critical work without recognition or protection. And in the event of an incident, they become the easiest target.

We think that’s wrong. And we’re working to fix it.

Together with our manager Steve Boot and in discussion with SSI, we’re developing a simplified, practical certification pathway focused specifically on what these workers actually do — the relevant parts of gas blending for their real job, clearly taught, properly assessed, and formally recognised.

It’s in progress. There’s red tape. These things take time. But SSI are interested, and we’re not letting it go.

Our Burmese tank team are some of the most dedicated, capable people we’ve ever worked with. They deserve proper recognition and legal protection. Getting this right matters to us as much as the turtle data.
