Aperçu
The Signature VM Coastal safeguards data quality, opens up new and unprecedented opportunities to the scientific community, and offers operational convenience and reduced complexity.
The Signature VM Coastal package includes the Signature1000, 500 or 250, allowing for great versatility in both the vessel-mounted and bottom-mounted configurations. By using a state-of-the-art and user-friendly vessel-mounted package, measurement errors and initial installation time can be greatly reduced.

Setup
The in-water serviceable sea valve solution is a convenient mounting choice for offshore operational vessels. The transducer head can also be mounted with a bracket for permanent pole or hull mount structures. The system connects to a junction box for power and communication.
Deployment
A type-approved sea valve solution makes the ADCP in-water serviceable. Data is streamed directly from the hull of the vessel into the control room in real time during operation.
Data
Designated software provides real-time current speed and direction in a 3D profile plot below the vessel, a history plot for predicting future windows of opportunity, as well as other views of information from the system for operators to make decisions at a glance. Data can also be easily fed into a third-party software.
