Teledyne Marine has announced the launch of the
HydroPACT 440 MK2, an upgrade of its market-leading subsea pipe and cable tracking system.
Building on more than 30 years of trusted offshore performance, the MK2 has been engineered as a robust, future-proof upgrade that still offers the familiar user experience and operability, yet ensures long-term continuity of supply and operation for customers across multiple sectors.
The
HydroPACT 440 has been the industry standard since its introduction in the early 1990s, playing a vital role in the installation, surveying, and verification of subsea pipelines and cables. Widely used in offshore energy, telecommunications, and defence applications, the system provides reliable, real-time tracking and measurement—critical proof-of-lay data and ongoing monitoring for assets already in situ. Generations of offshore personnel are trained on its operation, making ease of use and continuity essential for this new model.
Teledyne Marine has invested in a comprehensive redesign to secure the long-term future of the product. The result is a modernised system that maintains the same operability, with the addition of new architectural features, whilst retaining the same performance and familiar user experience.
“After many months of trials and testing, we’re extremely proud to introduce the HydroPACT 440 MK2,” said Jeremy Harrison, Business Manager at Teledyne Marine.
“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.”
What’s new in the HydroPACT 440 MK2?
Titanium subsea housing – lighter, more compact, and depth rated to 6,000 meters as standard.
For the first time
the MK2 system is offered as a 24Vdc single subsea pod, reducing cost and complexity. Especially suited to the newer eROVs now appearing in the market.
New Windows 11 topside computers – New SDC11 and RMC11 units for enhanced survey workflow.
The DeepView operating system has been upgraded to be Windows 11 compatible – ensuring familiarity for long-standing users while supporting modern capabilities.
The
HydroPACT 440 MK2 retains the system’s hallmark flexibility, it can be deployed on a wide variety of larger ROVs and trenchers enabling operators to conduct their own surveys and verify their work, and thereby helping to reduce operational costs.
Upgrade and replacement options are also available for users of the legacy HydroPACT 440 systems.
Importantly, the HydroPACT 440 MK2 is being launched at the same price as the previous model, reinforcing Teledyne Marine’s commitment to customer value as the product enters its next generation.
The HydroPACT 440 MK2 is available to purchase now and the system will make its official debut at
Oceanology International 2026, taking place 10–12 March in London.
