Hull Cleans & Inspections

Protect your vessel's performance with full-service hull maintenance. We offer detailed inspections, marine growth removal, anode replacement, and photo/video documentation. Non-Destructive Testing (NDT) is also available to assess structural integrity and prevent long-term damage.

Salvage Operations

Available 24/7 for emergency or scheduled salvage jobs, we recover sunken vessels, heavy machinery, and submerged equipment. With lift bags capable of up to 80 tons, we safely manage both shallow and deep-water extractions with precision and care.

Sub-Sea Construction
& Demolition

From installing underwater infrastructure to dismantling old structures, our divers are equipped for complex construction and demolition tasks. Using tools like Broco cutting systems, underwater chainsaws, and grinders, we handle everything from pile cutting to full structural removal.

Moorings

We install, inspect, and maintain moorings across the Marlborough Sounds, D’Urville Island, Lyttleton, and Kaikōura. Our divers ensure correct placement and servicing of both swing and fixed moorings, using robust techniques and reliable hardware to keep vessels secure.

Scientific & ROV Inspections

We support research and environmental projects with both diver-led and R.O.V. surveys. Our services include seabed mapping, habitat monitoring, structural inspections, and real-time video capture — helping scientists and consultants gather the data they need safely and accurately.

Vessel Hire

We offer vessel hire options, including the ‘Imogen III’, smaller dive boats, and our 18m catamaran ‘Willie-O’. Through key partnerships, we also have access to 13 additional vessels and work with trusted providers like Johnson’s Barge Service for transport and logistics.

Film & TV Production

We assist film and television crews with safe, professional underwater production support. From camera operation to dive coordination and safety logistics, our team helps bring underwater scenes to life — without compromising safety or quality.
