🚤 New Vessel for the Fleet – “SOUTHERN BLUE” 🌊

We’re excited to introduce SOUTHERN BLUE, our newly acquired Fyran 620, which has just joined the Bay Underwater Services fleet.

After a quick refurbishment and equipment upgrade to meet Maritime New Zealand requirements, this versatile vessel is now ready for work — and has made the long journey from Papamoa down to Bluff to join our Southern team.

A big thanks to everyone involved in the prep, compliance, and delivery. Another step forward in strengthening our capability across Aotearoa. 💪⚓️

⚓ Pier Refurbishment — Protecting Infrastructure Below the Waterline 🌊

Our Southern Lads are busy on another pier refurbishment project, this time installing Denso Pile Casings to strengthen and protect the existing piles.

This system provides long-term corrosion prevention and structural reinforcement — extending the life of marine assets exposed to harsh conditions.

There are several critical steps involved in the Denso system, and our commercial diving team are accredited installation experts, ensuring every project is completed to the highest standard of safety and quality.

Another solid effort from the team keeping our coastal infrastructure strong 💪

Commercial diving isn’t just a job — it’s a commitment.

Long days, unpredictable conditions, and time spent away from home and family come with the territory. The work can be tough, dirty, and demanding — but it’s also rewarding, full of challenge, and constantly evolving.

Every project brings new environments to adapt to and lessons to learn. From calm harbours to deep reservoir inspections, our team takes the good jobs with the bad, always with the same professionalism and pride in what we do.

It takes dedication to keep showing up, to keep learning, and to keep diving — no matter the conditions. That’s the spirit that drives Bay Underwater Services NZ Ltd and the people who make it what it is.

💧 Keeping the Power Flowing — Hydro Dam Maintenance by Our North Island Team ⚡️

Our North Island commercial diving team has been hard at work clearing debris from a hydro dam to help it operate more efficiently and safely.

Removing built-up material around the intake and infrastructure is an essential part of maintaining optimal water flow, reducing stress on equipment, and ensuring maximum power generation.

It’s a tough job — often in challenging conditions — but our divers take pride in knowing their work directly supports clean, renewable energy for communities across Aotearoa.

🚤 Pipeline Marker Installation — Another Day at the Office for Our Southern Lads 💪

Our commercial diving team has been busy installing a pipeline marker buoy for a valued client.
Different coloured buoys serve specific purposes out on the water — and this yellow buoy indicates the presence of a subsea pipeline below.

It’s a simple but vital part of marine safety — helping vessels navigate safely and protecting critical underwater infrastructure.

Great work by our Southern team for getting another job done efficiently and safely 👏

🌊 World Fisheries Day: Protecting Our Oceans, One Dive at a Time 🐟🤿

Today we celebrate the incredible communities, partnerships, and innovators driving sustainable fisheries around the world. Healthy fisheries depend on healthy habitats — and divers play a vital role in monitoring, restoring, and protecting these underwater ecosystems.

From mapping coral health to removing ghost nets and supporting sustainable harvest practices, divers are the eyes and hands beneath the surface — helping us better understand how human activity impacts marine life and how we can safeguard it for future generations.

By partnering with local fishers, conservation scientists, and coastal communities, we can ensure that fisheries thrive sustainably, providing food security and livelihoods while maintaining the delicate balance of marine ecosystems.

Let’s continue to work together — for our oceans, for our fishers, and for the future of our blue planet. 💙🌍
