Precise positioning
The rigid TH-Series Through-Hull Deployment Unit is engineered for accurate subsea instrument positioning aboard vessels operating in demanding survey and navigation conditions. It was originally developed for USBL deployment and control, but its design also supports a wide range of acoustic positioning systems.
Versatile Application
Although developed with USBL instruments in mind, the TH-Series is built for broader use. Its flexible configuration allows accurate deployment and control of different acoustic systems, making it suitable for varied vessel types, mission profiles and underwater operational requirements.
Robust Construction
Built for harsh marine environments, the TH-Series is designed to withstand demanding operational conditions for up to thirty years. Its strong mechanical structure supports long-term reliability while helping operators maintain dependable performance in intensive day-to-day use.
Modular Efficiency
Standard components and a modular design make it possible to create cost-effective tailor-made systems with short lead times. The same design philosophy also helps keep assembly and maintenance practical and competitive for operators working across global marine markets.
Intelligent Operation
The TH-Series features a modern servo-driven operating system with predictive maintenance capabilities, helping extend service life while reducing unnecessary maintenance costs. A clear display provides immediate operational feedback, while optional remote access allows DECK to support evaluation and intervention when needed.
Tested and Safeguarded
Each unit is analysed with advanced CAE tools and tested through extensive simulations before live operation. Backup functions such as manual gate valve control, manual pole recall, manual closing and raising, plus third-party quality assurance testing, help ensure reliable performance under any circumstances.

Frequently Asked Questions
What Intriques People Most About TH-Series Through-Hull Deployment Unit
A through-hull deployment unit is used to lower, position and recover subsea instruments through the vessel hull in a controlled way. DECK’s TH-Series is designed for precise subsea instrument positioning on vessels involved in underwater surveying and navigation.
The TH-Series was developed specifically for deploying and controlling USBL instruments, but its design also supports a wider range of acoustic positioning systems. This makes it suitable for vessels that need accurate deployment of subsea survey and navigation equipment.
The TH-Series is built with a robust modular construction designed to withstand severe environmental and operational conditions for up to thirty years. It also includes features such as a manual gate valve and manual pole recall to help maintain functionality under difficult circumstances.
Yes. The TH-Series uses a servo-driven operating system with predictive maintenance features, a display for live performance feedback, and optional local and remote control capabilities. Optional remote access also allows DECK to evaluate and intervene if a problem occurs.
Before live testing, DECK Marine Systems evaluates the TH-Series using CAE-based analysis and simulations to assess strength, durability and performance under operational and accidental scenarios. The company also offers quality assurance tests in the presence of third-party inspectors and can provide certificates when required.
