Complete control of installations and seabed conditions in regulated waters and waterways

To ensure safe and efficient operation of hydropower facilities, precise mapping and regular inspections are essential.

Vassfall offers a wide range of services that give our customers full control over infrastructure, seabed conditions, and technical installations.

Seabed Mapping with ROV and Geoscanner

We use modern ROV technology and geoscanners to map seabed conditions in reservoirs, waterways, and marine environments. This provides detailed data on sediment, erosion, objects, and general underwater conditions—information that is critical for safety, operations, and future planning.

Depth Measurement

Accurate depth measurements provide a solid foundation for operational decisions and risk assessments. Our measurements deliver precise profiles of the underwater topography and can be performed as standalone services or as part of a comprehensive mapping package.

Inspection of Equipment and Installations

We perform visual and technical inspections of barrier installations and other major structures in contact with water. This includes documentation of condition, deviations, and recommended corrective actions.

Maintenance and Service

Based on inspection findings, we carry out the necessary maintenance, replacement, and improvement of equipment. Our goal is to extend service life, optimize performance, and reduce risk. We also offer annual service agreements that include scheduled inspections and detailed reporting.
