UH-Series Under Hull Deployment Unit
About UH-Series Under Hull Deployment Unit
The UH-Series Under Hull Deployment Unit is designed for vessels where internal hull space is limited, but reliable subsea instrument deployment is still essential.
With a compact under-hull structure, the UH-Series provides a durable and cost-effective alternative to traditional through-hull deployment systems. While larger through-hull units can require several metres of internal height, the UH-Series keeps the main unit compact and practical for vessels where available space is at a premium.
Built for hydrographic and survey operations, the unit supports controlled deployment and retraction of sonars, echo-sounders and acoustic positioning systems. Its rugged marine-grade construction, optional hull gates and retractable design help protect sensitive instruments from underwater obstacles, ice and demanding marine conditions.

Compact Under-Hull Design
The UH-Series is built for vessels where free space inside the hull is limited, offering a compact alternative to larger through-hull deployment systems.
Cost-Effective Deployment
By avoiding the need for a full-height through-hull unit, the UH-Series helps reduce installation complexity while still supporting professional subsea instrument deployment.
Protected Instrument Handling
The retractable design helps protect sensitive sonars, echo-sounders and acoustic positioning systems from underwater obstacles, especially in demanding or ice-prone waters.
Rugged Marine Construction
Built from marine-grade, corrosion-resistant materials, the UH-Series is engineered for long service life and low maintenance in challenging marine environments.
Optional Hull Gates
Hull gates can be added for extra protection of sensitive instruments while also helping maintain the vessel’s hydrodynamic properties during operation.
Intelligent Operation
The unit can be equipped with servo-driven control, predictive maintenance features, remote diagnostics and manual retracting backup for added operational security.

Frequently Asked Questions
What Intriques People Most About UH-Series Under Hull Deployment Unit
The UH-Series is used to deploy and control subsea survey instruments such as sonars, echo-sounders and acoustic positioning systems from under the vessel hull.
It is a good choice when there is limited free space inside the vessel hull and a traditional through-hull deployment unit would be too large or impractical.
The UH-Series has a compact structure of around 1 metre in height, while through-hull deployment units can require significantly more vertical space.
Yes. The retractable design helps protect sensitive instruments from underwater obstacles, and optional hull gates can provide additional protection.
The UH-Series can be configured with either electric or hydraulic drive, depending on vessel systems and operational requirements.
Yes. The system can include local and remote control options, remote diagnostics and bridge integrated control, depending on the selected configuration.
