Our commercial dive team specialises in boat mooring installation, maintenance and compliance; pontoon installation – including connections and towage; and cyclone mooring installation.

We inspect and issue mooring compliance certificates, giving you quality assurance and peace of mind.

Based in Cairns, we annually service public-use Great Barrier Reef boat moorings from Moreton Bay in the South to the Torres Strait in the North. We’re often able to combine multiple client jobs on the same voyage, therefore are able to offer highly competitive pricing structures.


‘Mooring Compliance’ Commercial Divers

Tim North Marine’s commercial dive team provides compliance paperwork for boat moorings, pontoon moorings, helipad moorings and other marine structures/watercraft, throughout the Great Barrier Reef and Torres Strait region.

We issue MSQ Compliance Paperwork, QPWS Compliance Certificates and GBRMPA Compliance Certificates – where applicable.

As mooring specialists, we are extremely well acquainted with what you expect from a commercial dive provider. Our experienced team assesses your mooring/s and give you peace of mind beneath the surface.

Although nearly all mooring inspections are routine, in most circumstances, we are fully equipped to perform any on-the-spot maintenance as necessary – from minor repairs to significant change-outs. We strive to ensure no unnecessary delays in making sure your mooring is compliant for use.

We also offer competitive quotes for mooring installations, inspections and ongoing maintenance elsewhere in Australian waters (EEZ).
