• Simulation of anchor and riser placement in water column (catenaries)
• Real-time estimation of anchor chain tensions without needing tension measurement sensors

For cable lay operations specifically, you get:

• Cable route design and vessel route simulation
• Real-time positioning, monitoring, cable detection and visualisation

Offer your clients a more comprehensive service

A real-time 3D view allows your clients to follow the operation. Also, they benefit from a reporting feature that offers automatic generation of detailed documentation on eg riser/anchor status, clearance distance and anchor chain touchdown point (TDP).

With NaviSuite Beka as the software bedrock of your rig move operations, you can use your existing communications hardware more efficiently, saving you the cost of purchasing additional equipment.

The software allows for communications between the rig/barge and tugs via telemetry with up to three multiplexers or WLAN – or a combination of the two media types, depending on your needs. The bandwidth-efficient communications protocol ensures a faster data throughput and consequently reduced communications costs.

Additionally, licences for tugs are available at a low cost. This means that you get an operational software tool on board all vessels involved in the operation without breaking your budget.

AIS integration gives you a complete overview of all vessels in the operation area and ensures you a backup option if the telemetry/WLAN connection is lost, thereby eliminating the risk of downtime due to communications issues.

Choose between various rig move operation management setups

You can choose between various operation management setups. For example, the entire operation can be managed from the rig/barge, with tug operators following it on a display via an auto zoom/pan feature and delivery of commands and runline/waypoint assignments.

Alternatively, you can co-manage the operation with one or more tug operators, enabling them to, among others, respond to assignments and change anchor status (picked-up, dropped, etc).

The NaviSuite Beka software offers high-performance, virtually instant anchor chain catenary simulation. You can make changes to all parameters and plan the next steps of the operation on the fly, and the changes will immediately be visible on the screen. Moreover, you can share the information with the tug operators as well as shore-based staff who are carrying out support and monitoring.

The entire operation is managed via a centralised rig/barge server and command centre, which reduces mobilisation and operation costs. You can design or import multiple runlines and waypoints, as well as manage anchor status and locations of up to 16 anchors manually or automatically.

The advanced catenary algorithm behind the catenary feature of NaviSuite Beka has been developed and theoretically verified by the  independent, non-profit Danish research organisation the Alexandra Institute (member of the Danish GTS – Advanced Technology Group), and tested in real-life operations by the survey company iSURVEY (today Reach Subsea).

In addition to the advanced 3D display of all the objects involved in the operation, the software solution offers a comprehensive 2D display of high-quality catenary calculations that allows you to dive into the details of each anchor’s catenary. It is easy to use and offers instant results upon configuration changes.

A tension monitoring feature displays all the chain sections of all anchors, automatically colour-coded to illustrate the tension on each section. This feature also includes a three-level alarm function with user-defined limit values.

Easy integration with third-party systems and other EIVA software

Standard protocols such as the Inter-Vessel Survey Data Standard Telemetry Protocol IMCA S 006 are supported. This makes for quicker and easier integration and data exchange with systems used by third-party operators involved in the project, and you do not have to spend time on additional system configuration.

NaviSuite Beka is based on the NaviPac solution for offshore navigation and acquisition, which is widely used internationally. It offers seamless integration with the other solutions in the EIVA NaviSuite software family and consequently easy data import and export. Moreover, training costs are kept to a minimum, as the crew use the same software suite for various types of operations.

Materials property database

The catenary solution is delivered with an extensive library of chain components such as anchor, buoy, cable, chain and joints. You may furthermore define or import new components.

2D catenary monitoring

The catenary module is a stand-alone application used either in planning mode or live, together with NaviPac. It uses physical catenary simulation to estimate all parts of multiple catenary curves supporting cable, wire, chain, lifters, joints etc.

Change DTM

The catenary data model uses the seabed as reference and can use both terrain model and along-route profile of fixed depth as reference.

Suggest anchor position based on direction, configuration and desired tension

The system helps in calculating suggested anchor position based on either angle or tension by running iterative processes to obtain the best match.

Calculate 3D catenary using currents

The catenary model supports compensation for 3D current and will make final curvature and touch down based on the defined current.

Real time recalculation of caternaries

Catenary calculations act instantly as all components in the chain will have an impact on the resulting curve – as illustrated here by adjusting buoyancy.

Display catenaries in connected 3D displays

NaviPac version 4 connects to NaviCat. All chains and raisers are estimated instantly based on navigation and sensor inputs, and the catenary data model is sent to the HMD for graphical display. The entire 3D scene can be exported as Mesh for external use and documentation.

3D seabed terrain 

Seabed terrain can be visualised in a 3D environment.

Multiple Map Views

Multiple Map Views are available.  Each individual Map View window can be configured separately to display only the information required.

Background Maps 

Background Web Map Service (WMS) maps can be displayed.

Import 3D models 

3D models can be imported into NaviModel (drag and drop into the Map View window).

Link 3D models to live objects 

3D models can be linked to any live objects (Vessel, ROV, Scanfish etc).

2D, 3D and side-view displays 

2D, 3D or Side views allows the user to quickly change the view facilitating better data interpretation.

Visibility Slider 

Visibility slider allows users to compare different DTM’s quickly.  This enables comparison over time or between different data processing methods.

Control colours, lights, details 

DTM light and palette settings can be changed at any time.

Profile views 

Create fly-through videos 

Fly-through videos can be created for project or promotional presentations.

Display live position of a vehicle

NaviSuite supports display of vehicle data based on the NaviPac data feed. You can display the main vessel along with one subsea vehicle, such as an ROV or ROTV, on an unlimited number of local and remote displays. The data can be shown graphically in multiple map views.

AIS tracks

NaviSuite supports integration with AIS receivers. The data can be shown in a dedicated AIS window and overlaid in the NaviPac window. You can perform, read and utilise vessel dimension information.

Display north-up, heading-up, route-up

Each Map View can be designed and controlled individually when it comes to content, overlays and layout. Map Views can be 2D, 3D or side-views, and orientation can be user defined, north-up, vehicle up or line up.

Manual waypoint drawing

NaviSuite supports a series of runline and waypoint formats including our own RLX/WPT format, ad generic ASCII readers. You can also draw lines and points directly in the Map View.

Various runline patterns (parallel, cross, star)

You can inherit multiple lines based on the base line defined, such as parallel or cross lines to get an optimal route plan.

Vehicle control panel for multiple vehicle runlines and display DOL

Assignment of lines and waypoints are handled through the dedicated Vehicle Control view, as you may control multiple vehicles simultaneously. Each controlled vehicle will be available as distance offline indicator (DOL/DCC) and various runline information (along line, target ETA etc).

Distance to waypoint

Waypoints are handled in a similar manner to runlines, as assignment of the waypoint is done in the Vehicle Control View. Hereafter, an artificial runline is created from the vehicle to the point and NaviPac monitors the range/bearing to the destination. and can a,.o. feed that into autopilots and DP systems.

Multi-object live range/bearing

In NaviSuite, you may pair live vessels and monitor the range/bearings between them for online display as live data and range information on Map Views.

Auto-pilot (NMEA) control

When using runlines and waypoints you may connect NaviPac to autopilot systems using e.g., standard NMEA formats and pass cross-track error and destination waypoints on to the equipment.

DataUnits

NaviSuite supports use of other data units in addition to metric. The unit is selected in the project settings and all definition fields are then assumed to be in the selected data unit. 
NaviSuite will follow the selected data unit, but you may, by using a simple keystroke, toggle between metric and data unit if required.
Data recording will still be metric to guarantee data integrity, but data outputs can be selected freely.
