Commercial Divers Key to Pacific Towing’s Salvage Success
Marine salvage is a discipline defined by urgency, complexity, and risk. Every operation is different, and every operation is high-stakes – multi-million-dollar assets, lives, and marine ecosystems are often at risk. In Melanesia, Pacific Towing (PacTow) has consistently demonstrated the expertise and resolve to tackle these challenges head-on. A homegrown Papua New Guinean business headquartered in Port Moresby, PacTow has earned its reputation as the region’s leading marine services provider. At the core of nearly every salvage operation PacTow undertakes is its commercial diving team – the only permanently based unit of its kind in Melanesia.
Salvage Leadership with Global Recognition
Over the past two decades, PacTow has completed close to 100 successful salvage and wreck removal operations, involving a diversity of vessels ranging from bulk carriers to general cargo ships, and from fishing vessels to yachts. These projects have taken PacTow not only across PNG but also further afield – throughout Melanesia, into Micronesia, across to Indonesia, and even into northern Australia. This extensive track record underscores both the demand for and the trust in PacTow’s capability.
That capability is further evidenced by PacTow’s standing in the global salvage community. It remains Melanesia’s only full member of the International Salvage Union (ISU), the body that represents the world’s leading professional salvors. It is also the region’s only member of the International Spill Control Organization (ISCO), reflecting its role in protecting marine environments. These affiliations are not merely symbolic; they attest to PacTow’s adherence to international standards of salvage practice, safety, and environmental stewardship.
Commercial Diving: The Essential Ingredient
What distinguishes PacTow from many other salvage operators is the central role of its commercial diving team. Salvage operations – whether patching hull breaches, sealing fuel tanks, or rigging heavy lifts – are almost always dependent on skilled divers working in hazardous conditions. PacTow’s diving team brings a combination of local knowledge, international training, and experience that is unmatched in the region.
There are 18 divers – all Papua New Guinean – in PacTow’s commercial diving team. Diving Manager Ricky Leka has been diving for PacTow for 20 years and leading his team for 13. Another seven divers have been with the company for more than 10 years.
Uniquely, the PacTow diving team is the only permanently based commercial diving operation in Melanesia. This ensures that PNG and neighbouring nations have 24/7 access to a highly qualified dive team without the costs and delays of flying in specialists from more developed countries further afield. The team holds both PNG and Australian diving certifications – a rare dual qualification that guarantees compliance with regulatory frameworks.
PacTow’s divers also regularly travel for international training, honing skills in subsea engineering, salvage techniques, and safety systems. The company also supports PNG’s diver recompression facility in Port Moresby, and several of its divers are certified hyperbaric chamber technicians.
Beyond Salvage: Serving PNG’s Oil and Gas Sector
While salvage remains the most high-profile demonstration of PacTow’s diving expertise, the team’s contribution extends well beyond emergency response. As PNG’s oil and gas industry continues to expand, demand for reliable and locally available subsea services is growing. PacTow’s divers are increasingly engaged in underwater inspections, maintenance of subsea infrastructure, and pipeline support. Their capacity to provide a cost-effective and certified local solution is vital for a sector that values safety, efficiency, and the minimisation of downtime.
A Regional Asset with Local Commitment
PacTow’s investment in its commercial diving team is not just about building technical capability; it is also about developing local capacity. This is evident in the five young commercial diving trainees currently in PacTow’s team. By developing homegrown divers and technicians, the company contributes to skills transfer and workforce development in PNG. This ensures that the nation has its own cadre of diving professionals who can respond to crises and support its economic growth.
Conclusion
Marine salvage will always be a demanding field, and in Melanesia, it is PacTow that consistently answers the call. Central to that capability is its commercial diving team – the region’s only permanent professional diving operation, staffed by divers with international qualifications and unparalleled local knowledge.
Pacific Towing is Melanesia’s largest marine services business. It employs more than 250 staff and has a fleet of 20 vessels. It provides a broad spectrum of marine services including towage, emergency response, commercial diving, life raft services, and salvage. PacTow is part of the larger maritime and land Logistics Division of the Steamships Group.

E/V Nautilus Explores Cook Islands’ Deep-Sea Frontier with 4K Imaging Technology
The exploration vessel Nautilus has begun an ambitious deep-sea mission to study the hidden ecosystems of the Cook Islands’ Marae Moana, deploying a groundbreaking 4K camera system that promises to reveal the ocean depths in unprecedented clarity.
For the first time, scientists are testing the MxD SeaCam, an ultra-high-resolution camera developed by DeepSea Power & Light in collaboration with the Monterey Bay Aquarium Research Institute. Encased in a titanium housing, the camera can capture crystal-clear imagery at depths reaching 5,500 metres, where sunlight fades and water pressure is immense.
“This is more than new tech — it’s about seeing Marae Moana in ways never possible before,” the Nautilus team said. “Every image helps our scientists identify deep-sea corals, sponges, and habitats that make our ocean unique.”
The camera is being tested aboard E/V Nautilus using remotely operated vehicles (ROVs) Hercules, Atalanta, and Little Hercules, as the team explores seamounts and abyssal plains across the Cook Islands’ vast marine territory.
Prime Minister Engages Live with Scientists at Sea
Cook Islands Prime Minister Mark Brown, who is the concurrent minister Responsible for Seabed Minerals, joined the expedition team via a live ship-to-shore interaction on Day 16 of the Deep-Sea Habitats of the Cook Islands Expedition (NA176).
Connecting in real time from Rarotonga, Brown spoke with Dr John Parianos and Tanga Morris Jr of the Seabed Minerals Authority (SBMA) Knowledge Management Division, Michael Parrish of the Ministry of Marine Resources, and Dr Antony Vavia.
Together, they discussed life at sea, recent discoveries within Marae Moana, and the importance of building Cook Islands’ capacity in deep-ocean science and stewardship.
Mapping the Unexplored Depths
The Ocean Exploration Trust (OET), with support from NOAA Ocean Exploration through the Ocean Exploration Cooperative Institute, is leading the 21-day mission — the final Nautilus expedition for 2025. The project was developed in close partnership with the Cook Islands Government and the Cook Islands Seabed Minerals Authority, following a formal request for U.S. scientific collaboration.
Located in the South-Central Pacific, the Cook Islands comprise 15 islands surrounded by nearly 2 million square kilometres of ocean — most of it still unmapped and unexplored. This deep-sea region includes vast abyssal plains, plateaus, and seamounts, forming part of Marae Moana, the Cook Islands’ large-scale marine managed area established to balance environmental protection with economic development.
Cutting-Edge Exploration
Aboard E/V Nautilus, the international science team — including six participants from the Cook Islands — will document seabed and biological diversity across the Manihiki Plateau and surrounding abyssal plains. Surveys will use ROV Little Hercules and ROV Atalanta for high-resolution imaging at depths between 4,500 and 5,500 metres, while ROV Hercules will operate at shallower depths of 1,500 to 3,800 metres to collect environmental data and physical samples.
During the expedition, both Hercules and Little Hercules will be equipped with the MxD SeaCam for field testing. The innovative 4K system integrates a Sony HDC-50 broadcast camera and a borosilicate dome, engineered to perform reliably in extreme subsea conditions.
“Collaborations like this showcase E/V Nautilus as a test platform for new technologies,” the OET said, noting that such projects highlight NOAA’s commitment to advancing ocean exploration through public–private partnerships.
Bringing the Ocean to the World
The entire expedition is being streamed live on NautilusLive.org, allowing audiences worldwide to follow the journey in real time. Using telepresence technology, viewers can engage with the crew, ask questions, and gain behind-the-scenes insights via social media and classroom connections.
Free educational Q&A sessions are also being offered to schools across the globe, providing a unique opportunity to interact directly with the scientists and engineers aboard.
This expedition marks the culmination of E/V Nautilus’s 2025 field season, which comprised six missions aimed at strengthening global understanding of the deep ocean. Data from these voyages will contribute to major international initiatives such as Seabed 2030, Beyond the Blue: Illuminating the Pacific, and the U.S. National Strategy for Ocean Mapping, Exploration, and Characterization.
Through open access to all collected data, NOAA and OET hope to build upon decades of deep-sea research — ensuring that the Cook Islands’ Marae Moana continues to inspire both scientific discovery and sustainable stewardship.
