Supply of Public Mooring & RPM Maintenance Services in Great Barrier Reef Marine Park – QPWS

Great Barrier Reef Marine Park, QLD Australia

North Marine installs & maintains public-use boat mooring infrastructure and reef protection markers throughout the Great Barrier Reef Marine Park. Client: Queensland Parks and Wildlife Service (QPWS) North Marine has held an SOA with QPWS since 2010 (formerly as 'Tim North Marine') - with the most recent SOA awarded in 2019. Scope of Work North Marine is a key contractor in the SOA to maintain public-use boat mooring infrastructure and reef protection markers for QPWS. Work is conducted throughout the Great Barrier Reef Marine Park, including the northern GBR, Whitsundays and southern GBR. Maintenance voyages are conducted two-to-three times annually by North Marine, on average. Change-out voyages occur every four years, where mooring components are completely replaced. (Mooring parts are fully replaced, with the exception of the embedded screw anchor). North Marine typically uses the workboat 'Viking' for maintenance voyages and the larger 'Gulf Explorer' for change-out trips. Maintenance voyages include cleaning, exchanging defective parts, recording conditions and providing photographic and written evidence reports. North Marine ensures adequate replacement parts are ready to deploy and accordingly dispose of, or return to QPWS, faulty/unused equipment.  Importantly, North Marine fabricates moorings in-house and is a mooring component stockist. Being a local supplier reduces third-party costs to the client, and further minimises freight charges - resulting in budget savings. Mooring lines, with tackle, are fabricated in-house by our expert commercial diving department to exact specifications. An AMSA accredited Marine Surveyor routinely inspects fabricated mooring lines to ensure conformity with specifications. These logistically complex voyages involve extensive quality assurance, planning, reporting and compliance obligations. Critically, works are performed with minimal interruption to other reef users. As always, North Marine operates within all cultural and environmental controls set out by the Great Barrier Reef Marine Park Authority (GBRMPA), QPWS and applicable authorities.  Deliverables Clean, inspect & conduct routine maintenance on public moorings Clean, inspect & conduct routine maintenance on RPMs Conduct mooring change-outs, inc. installation of new mooring components Fabricate mooring lines & tackle (in-house) Supply of mooring components as required in SOA - Including pickup lines, buoy lanyards, rated shackles, thimbles, swivels, split-pins, riser buoys, line, ballast chains etc. Maintenance reporting across all assets - written & photographic Government Supplier - Local Contractor North Marine North Marine is a prominent Queensland marine contracting company based in the Port of Cairns in Far North Queensland, Australia.

Public Moorings & Reef Protection Markers Public moorings exist throughout the Great Barrier Reef region to reduce coral damage from vessel anchors. Reef protection markers primarily outline a reef protection area, where the use of vessel anchors is prohibited. Public moorings are available to all reef users. They are coded to indicate the class of vessel they may hold (vessel length), the time they can be used, and the maximum wind strengths, as applicable to each mooring.

Port of Cairns, Queensland and Fitzroy Island, Great Barrier Reef

North Marine's Commercial Dive Department was contracted to supply and install sacrificial anodes, including conducting cathodic-protection field-testing, in Cairns Harbour, Cairns Marlin Marina and Fitzroy Island in Queensland, Australia. Client: Far North Queensland Ports Corporation Limited - trading as Ports North Ports North is a Queensland Government Owned Corporation. Scope of Work - Anode Replacement Project North Marine was engaged by Ports North to supply, remove and replace existing anodes and hanger rods. The anode contract involved inspecting/cleaning/restoring piles and surfaces, highly-skilled underwater welding work by North Marine professional divers, and rectifying bond cables. Any areas that were found not to be in alignment with current specification drawings were identified and addressed in accordance with Ports North directives. Anode replacement works were field-tested by a North Marine sub-contractor for quality assurance. This involved cathodic protection testing on the steel piles, by an ACA Certified Corrosion Technologist. North Marine's HIAB crane truck was used to lower larger anodes into the water. The works combined both shore-based and vessel-based operations, depending on available access points. 'Reef Safari' workboat was deployed for this project along with a team of experienced and skilled North Marine commercial divers and an on-site Project Manager. Considerations Managing the Anode Replacement Project presented numerous logistical challenges.

Green Island, Great Barrier Reef, Queensland

North Marine is engaged to salvage the 1954 underwater observatory from Green Island on the Great Barrier Reef and tow it to the Port of Cairns in Queensland. Client: Quicksilver Group - Great Adventures Scope of Work North Marine was contracted to Project Manage this complex operation. It included salvaging the structure from the ocean floor, transporting it to Cairns by barge and overseeing demolition. The experienced commercial diving department at North Marine successfully executed the salvage and removal of the submerged observatory, located at Green Island out of Cairns. North Marine's divers excavated the partially-buried underwater structure, following complex environmental planning and stakeholder consultations. The observatory was then towed onboard a barge to the mainland, where historic parts of the structure were retained by Great Adventures staff prior to demolition. In situ since 1954, underwater dredging was required to dislodge the 38-ton-weight. It was floated by lift bags, maneuvered and lifted by crane onto a barge for towage to the mainland. Divers then cleared 2 tons of debris from the site, including 44-gallon drums & steel railway track 'weights'. North Marine successfully completed the contract with all project objectives delivered in full. The best outcome was achieved for the client.

Download Case Study About the Green Island Underwater Observatory The underwater observatory at Green Island was the brainchild of Vince Vlassoff, a 37-year-old Australian-born Engineer, and Lloyd Grigg after they met on a crocodile safari cruise operated by Vlassoff. Before snorkelling or scuba diving had become mainstream activities, this pioneering piece of architecture truly was a revolution in reef tourism, which up until this point had largely been occasional ferry trips taking people to offshore islands for a day trip. Never before had the general visitor had access to freely view the Great Barrier Reef beneath the surface. The entrepreneurial pair imagined an underwater theatre, unlike anything ever constructed of its kind before. They envisioned a place where the public could venture beneath the waves to a chamber of windows, whereby they could witness the marvellous fish, coral, and aquatic life to be seen. Construction of the chamber began in 1951 and took twelve months from planning to final submersion – an incredible time frame considering the challenge of the task and all the unknown factors. For nearly 60 years, the underwater observatory delighted visitors and provided a means of viewing the incredible underwater world.   Visit these pages for more information on North Marine services Marine Services Commercial Diving Services
