In this video, Adam Junner, Hydrographic Surveyor at NORBIT Subsea, explains the rationale behind using a hull mount installation for the WINGHEAD i80S, and outlines the operational and performance considerations compared to traditional over-the-side pole mount installations.
The video demonstrates how hull mounting increases the submersion depth of the sonar, placing it below surface wave action where noise is reduced, thereby improving data quality. It also explains the importance of positioning the sonar below the vessel’s keel for optimal performance and why, on larger vessels with longer drafts, a hull mount installation can be a more practical way to achieve this requirement.
It further outlines how permanent hull mount installations remove the need for regular deployment and recovery, allowing vessels to transit at full speed when the sonar is not in use. The video notes that hull mounting is commonly used on larger vessels where over-the-side mounting is impractical, and confirms that all NORBIT sonars can be configured for hull mount installations, with complete design and installation support available from NORBIT Subsea.
