Precise, seamless, robust

Precision engineered, Marksman leverages the strengths of both USBL and LBL acoustics, providing enhanced precision and range redundancy through seabed transponder networks.

Marksman seamlessly integrates with your existing DP system, whether you’re running GE, Kongsberg, MT, Navis, Rolls-Royce or Wärtsilä.

Robust and reliable dual independent hardware configurations provide redundancy to ensure your critical operations can continue even if part of the system becomes unavailable. There is also option of operating in triple redundancy configuration through the augmentation of our inertial navigation technology – known as DP-INS.

DP-INS has been developed to meet regulatory requirements which state that deep water drilling units must be equipped with three independent positioning reference inputs to their DP system. Traditionally, an acoustic positioning system and two separate GNSS systems are used.

However, vulnerability remains should the acoustics be affected by aeration and noise and both GNSS systems simultaneously affected by signal disruption. The latter is particularly common around equatorial regions and during periods of high solar radiation. Marksman removes this vulnerability by reducing the reliance on GNSS.

How Marksman elevates your operations

The Marksman system, built on ground-breaking 6G and Wideband 2 technology platforms, offers a comprehensive solution that combines faster, more robust data transmission with precision acoustic ranging that remains immune to vessel and ROV noise.

This trusted system, widely adopted by leading offshore energy operators in the Gulf of Mexico, Brazil, and West Africa, delivers uncompromising precision and global tracking capabilities at any depth, while seamlessly integrating with DP systems. Its dual and triple redundant configurations, immunity to GNSS disruptions, and extended battery life make it ideal for semi-permanent seabed deployments.

The system excels in mission-critical applications including riser monitoring and dynamic positioning reference, while offering valuable additional capabilities such as acoustic riser angle monitoring, backup BOP acoustic control, and data recovery from seafloor sensors. With its future-proof platform, simple user interface, and proven reliability, Marksman is the premier choice for operators requiring robust performance in demanding offshore environments.
