NavView is a feature rich positioning and navigation package combining 4D Nav’s engineering, surveying and software development expertise with innovation and modern software technology.
NavView surpasses traditional real-time positioning software by incorporating awareness of 3D elements such as the seafloor and other objects including subsea structures, pipelines, risers, umbilicals and anchor. Combined with robust surface and subsurface positioning algorithms the result is a powerful real-time visualization package for the most challenging of offshore operations.
NavView is developed using an advanced architecture. This allows each NavView station to operate as a standalone navigation and visualization system and in addition, provides the ability to exchange data with other NavView stations or third party systems using web services.
This architecture enables full collaboration between geographically dispersed NavView stations via local and wide area networks (LAN/WAN). An example of this collaboration would be the ability to visualize and control an offshore operation from any global location, including onshore.
NavView integrates the European Petroleum Survey Group (EPSG) Geodetic Parameter Dataset maintained and published by the Geomatics Subcommittee of the International Association of Oil and Gas Producers (OGP). This provides an unambiguous and standardized means to configure system geodetics, minimizing the potential for error and discrepancy.
NavView features industry leading real-time 3D display of all system components in the operations area. This visualization of surface and subsea features (structures, pipelines, waypoints, etc.) together with the real-time positioning of dynamic objects (e.g. vessels, ROVs, riser lines, etc.) against a seafloor digital terrain model (DTM) improves monitoring and comprehension of complex operations.
NavView provides comprehensive 2D visualizations with extensive operator control. This includes selective display and configuration of each graphics layer as well as individual graphical entities. Native display of AutoCAD DWG files is supported using Autodesk RealDWG®.
NavView includes multiple additional intuitive views for the visualization of textual and graphical data including real-time charts, time series and dashboards. Each view is designed to support operator configuration to best suit individual operator and operation requirements.
NavView includes fully configurable workspaces that contain docking windows. This gives the users the ability setup multiple custom workspaces each with fully customized view layouts to best visualize complex operations.
NavView incorporates the ability to record data in real-time, including raw data as received at the input source, along with normalized observation data which is recorded to a robust SQL database. Custom ASCII data recording is supported via highly configurable custom data outputs which can write to any output stream including to file, network and serial ports.
The SQL data archive feature supports full SQL query operations and the export of data to assist with report generation, data analysis and post processing.
NavView supports real-time catenary modeling of discrete elements through the water column. These include: pipelines for S-Lay and J-Lay operations, anchor lines including complex systems using compound catenary calculations, and risers. Catenary modeling is performed using proprietary algorithms or the industry standard Orcina OrcaFlex™ Finite Element Analysis package.
The optional anchor handling module builds on NavView’s comprehensive 2D and 3D graphic visualization, configurable text displays, data logging, data querying, networking, and intuitive operation by adding user friendly anchor planning and management features.
NavView supports serial radio telemetry or IP networking for inter-vessel communications. Rigorous data validation and performance monitoring enhance reliability and operator confidence.
Anchor management is supported via the Anchor Planning and Anchor Manager tools which each have their own intuitive user interface. Anchor operations are easily monitored using NavView’s graphic and text displays. 2D Map windows showing all vessels, anchors and anchor lines color coded to indicate their state, with background drawings depicting the work area, provide a comprehensive operational overview in one glance.
NavView’s advanced 3D catenary modelling enhances the safety of anchor operations and provides spatial visualization and monitoring of anchor lines in relation to subsea assets.
NavView Anchor Module is the optimal real-time position and navigation tool for your anchor operations.

Pipelaying operations are supported using a layback model along with pipeline routes. Pipeline routes are entered manually by the user, imported from a file or imported directly by selecting a polyline from a background AutoCAD drawing in the 2D Map view.
Typical capabilities such as barge track generation and heading-to-steer determination based on the design pipe route and touch down layback are supported. These features are augmented by NavView’s extensive guidance configuration and visualization options plus innovative approaches to layback updates and touchdown position (TDP) monitoring.
The layback value can be entered as a single value and updated by the operator as required. Alternatively, the entire lay plan for a pipeline can be imported and NavView will automatically change the layback throughout the route negating the need for operator intervention during the lay. The locations where the layback changes occur are displayed in the 2D and 3D views.
NavView’s approach to ROV TDP monitoring enables switching between ROVs without requiring changes to TDP data recording or any windows displaying TDP tracking information on any networked NavView station. This simplifies the process and eliminates the potential of missing critical as-laid data due to an ROV switch.
Additional pipelay features include pipe tally and full cut-to-length calculation capabilities.
Heavy lift operations are modeled using a crane model which includes the pedestal, boom, sheaves and hooks. The crane is modeled with six degrees of freedom. Crane rotations are modeled using inputs for swing and boom angles. Finally hook positions are calculated using cable payout data.
The crane and its load are displayed in the textual, 2D and 3D windows. Spatial relationships of the crane’s sheaves, hooks and load to target locations can be configured to assist with the placement of the load.
NavView includes a calculation for computing the general motion (linear velocity, linear acceleration and heave) of any point on a vessel. Given the vessel’s heave, linear velocity, angular velocity and optionally angular acceleration for any point on the vessel, NavView computes the general motion for any other position or positions on the vessel. The monitored position can be a static offset position or a dynamic position such as crane tip during heavy lift operations. This information can be used to improve the safety of heavy lift operations.
