Teledyne Marine has launched the HydroPACT 440 MK2, providing a robust and future-proof upgrade to its long-standing, subsea pipe and cable tracking technology.
The MK2 version introduces several significant hardware and software updates. For the first time, the system is offered as a 24Vdc single subsea pod, a configuration specifically designed to reduce cost and complexity for the newer electrical Remotely Operated Vehicles (eROVs) currently entering the market. The subsea housing is now constructed from titanium, making it both lighter and more compact while providing a 6,000-meter depth rating as standard.
Jeremy Harrison, Business Manager at Teledyne Marine, commented, “After many months of trials and testing, we’re extremely proud to introduce the HydroPACT 440 MK2. Customers can expect the same credible, proven performance they trust, but in a refreshed design built to operate reliably for decades to come. Continuity and future-proofing were our guiding principles.”
To support modern survey workflows, the system includes new SDC11 and RMC11 topside computers. The DeepView operating system has also been upgraded for compatibility with Windows 11. These architectural changes ensure that while the system supports modern capabilities, the user experience remains consistent for those transitioning from legacy equipment.
The HydroPACT 440 MK2 remains flexible enough for deployment on a wide variety of large ROVs and trenchers, allowing operators to conduct independent surveys and verify work to help reduce overall operational costs. Teledyne Marine is offering the MK2 at the same price point as the previous model, with upgrade and replacement options available for current users of legacy systems.
The system represents an evolution of the industry standard that has been in operation since the early 1990s. Used extensively in telecommunications, offshore energy, and defence, the technology provides real-time tracking and measurement data essential for the installation and monitoring of subsea assets. This redesign focuses on securing the long-term future of the product while maintaining the familiar operability that generations of offshore personnel have been trained to use.
The system is available for purchase immediately and will be officially showcased at Oceanology International 2026 in London from 10–12 March.
