Groundbreaking technology transforms pipeline waterway monitoring. WSP vessel in water with controller With thousands of river and waterway crossings across the Firstgas network, checking submerged pipelines has always been an important part of its maintenance schedule. In the past, it's been a challenging undertaking, considered risky, time-consuming and providing only limited information. Thanks to new technology and a partnership with WSP, First Gas Limited can now survey waterways quickly, safely and with robust results. First Gas Limited talk to Derek Coombe, Firstgas Pipeline Engineer, about how waterway monitoring has evolved over the years, and how a new remote-controlled vessel has delivered a safer, more accurate method. Wading through rivers to monitor pipelines Ropes, probes and waders: early survey methods. It's vital to map its gas pipelines regularly and check what condition they're in, even when the pipes run through waterways. Previously, Firstgas relied on manual survey techniques, as Coombe explains: "In the early days, it was a person in waders with a rope tied around their waist, walking into the river with a probe. It was labour-intensive, risky, and the data didn't always show what was really happening beneath the surface." Although data collection methods improved over the years, they still required people standing in the water, which meant that sometimes rivers were too deep, too fast-moving, or too murky to be monitored. Divers might have been used in deeper waterways and followed accepted practices at the time; they still carried inherent risk, Coombe says, but "we were limited by depth, flow and visibility. If a diver went under, you lost visibility immediately and control over their safety." One day, trying to map pipelines in the Waipa River, Coombe decided he'd had enough. "The Waipa River was a real turning point for me. The current was strong, the willow trees created entanglement risks, and the logistics were huge. I had a real want to get people out of the waterway." WSP remote control survey vessel carrying out inspection From sonar-equipped kayaks to a new zealand-first vessel. Working alongside global engineering firm WSP, the first step was trialling a single-beam sonar mounted on a modified kayak. This improved data quality considerably, but risks remained; the kayak method needed someone on the water and extensive safety controls. Coombe recalls, "I was determined to keep people out of the water altogether, so I sent WSP a picture of a remote-controlled boat and asked, 'How could we do this better?'" WSP began investigating remote-controlled survey vessels as a safer alternative to traditional methods. The initial solution was a single-beam sonar boat equipped with GPS, survey instrumentation, a video camera, and radar. As the first system of its kind in New Zealand, WSP needed to obtain Maritime New Zealand approval to operate in local waterways. This required the development of detailed operational procedures, along with specialised training for operators working across lakes, rivers, and ports in Aotearoa. Building on this capability, WSP later expanded its fleet with a larger multibeam sonar vessel, further enhancing its remote survey capabilities in New Zealand. Coombe says, "A survey that used to take four hours by kayak can now be done in about 30 minutes. You programme where you want it to go, push start, and the boat does the work." The small vessel is operated from the riverbank (so nobody needs to be in the water) and provides a wealth of detailed information. Multibeam sonar provides near-continuous riverbed surface modelling and identifies rocks, logs, buried assets, and any other debris. Combined with drone LiDAR data, Firstgas can now create 3D visualisations of its network, making it easier to identify potential issues and erosion. "We're getting confident data now," says Coombe. "We're identifying shallow pipe and erosion issues much earlier than we ever could before." and able to undertake repeatable surveys for ongoing monitoring. Monitoring data image collected by the survey vessel "It doesn't get much better than this" The technology is now being used nationally and internationally, across a range of environments. It was recently used to map the Whanganui River in preparation for replacing the Dublin Street Bridge, with WSP team leader Peter Troon saying, "When it comes to underwater mapping, it doesn't get much better than this." "WSP took a real risk bringing this technology into New Zealand," Coombe adds. "They invested in it without any guarantee of work and it's paid off for everyone. The biggest win for me is that we're keeping people out of hazardous environments."

Amentum-led joint venture selected for $112 million clean-up at four European nuclear research sites. March 10, 2026 - CHANTILLY, VA., March 10, 2026 - A joint venture led by Amentum (NYSE: AMTM) has won a new framework contract as the lead decommissioning and waste management contractor for nuclear research sites in four European countries. Under the $112 million (€95.7 million) contract, awarded by the European Commission Joint Research Centre (JRC), the Amentum-led JV will provide decommissioning solutions to accelerate the cleanup efforts of JRC sites in Ispra (Italy), Karlsruhe (Germany), Geel (Belgium) and Petten (The Netherlands). "Amentum's robust track record of delivering European-funded projects on time and on budget in multiple countries, including prior experience working at JRC Ispra, made us the ideal choice for this contract," said Loren Jones, senior vice president and head of Amentum's Energy & Environment-International business. "We will leverage decommissioning and waste management techniques developed at the world's most complex nuclear sites, integrating innovative solutions to complex technical and project management challenges. Additionally, our strong ties to regulatory authorities across the European Union will serve as a vital asset in ensuring success." For more than 60 years, the JRC sites have addressed complex challenges in areas such as nuclear decommissioning, innovation, safeguards and non-proliferation by conducting research, providing scientific advice and supporting European Union policy makers. The decommissioning and waste management contract will cover structures such as research reactors, hot cells, accelerators, laboratories and other infrastructure where radioactive substances have been handled. The work will be delivered by an Amentum-led joint venture with WSP Italia, supported by sub-contractors TUV Rheinland and Protection Solution SRL. The JV's scope of work includes licensing, radioactive waste management, radiation protection, decommissioning and nuclear engineering, worksite management and safety, non-nuclear engineering, facility supervision and quality assurance. The JRC contract has a duration of two years with three potential two-year extensions.
