NORBIT iWBMSh

NORBIT iWBMSh

An integrated multibeam system using Applanix OceanMaster GNSS/INS for demanding survey conditions. Improved attitude performance supports coastal and offshore mapping, structure inspection and operations where vessel dynamics place greater demands on motion compensation.

Position and motion correction with OceanMaster

iWBMSh combines sonar observations with OceanMaster GNSS/INS position and attitude measurements. The integrated platform supports coastal and offshore bathymetry, pipeline surveys and structure inspection. Heading accuracy should be read together with antenna spacing and RTK conditions. Standard and narrow-beam options differ; features of iWBMSh STX or Stabilised versions are not automatically included in the standard iWBMSh package.

Applications and survey workflow

Bathymetric data supports harbour maintenance, dredging assessment, route surveys and the inspection of submerged infrastructure. Survey line spacing and frequency are selected to balance feature definition, coverage and the expected water depth.

Before mobilisation, the survey team defines the coordinate system, vertical reference and required deliverables. Mounting geometry, sensor offsets and time synchronisation are checked as one installation. Positioning quality, vessel motion and sound-speed conditions are reviewed during acquisition so that the final dataset can be assessed against the project specification.

Integration and deliverables

The selected hardware and software configuration determines the available outputs and interfaces. A practical workflow includes installation checks, a trial line, field quality control and documented processing. Depending on the sensor, deliverables may include a bathymetric surface, an inspection image, a point cloud or an interpreted sediment profile. Kordil can evaluate the platform, operating environment and intended use when defining the system configuration.
