OrcaFlex image gallery

OrcaFlex utilises a standard Windows GUI which gives good visualisation of model and results. It does not rely on text files for data input/output.

There are a variety of screenshots below which showcase the OrcaFlex UI, including wire frame and shaded graphics views, object data forms and results output windows.

Pipelay stinger

The pipelay stinger is modelled using line elements to represent the frame structure. The rollers are modelled using supports, with individual roller box rotation captured, including physical stops. Contact is highlighted by colour (white rollers are in contact, pink rollers are not).

Mid water arch

Showing multiple views in use simultaneously. In this case they are all shaded graphics 3D views, but could also be any combination of wire frame 3D views or results windows. This screenshot also includes the model browser at the left hand side, which helps you build, organise and navigate within your model

Lazy wave riser

Wire frame 3D view and curvature results window. The results window shows spikes in curvature as a result of the attached buoyancy cans. Instantaneous results are also available, which change as a simulation replay progresses.

LNG tanker offloading

Vessels can be coupled together, either directly or via intermediate objects. In this case, an LNG tanker is connected to an FPSO via a number of mooring lines and a series of loading arms. The loading arms are released and retracted during the simulation using constraint objects, before the mooring lines are released and the tanker moves away.

Model browser

The OrcaFlex model browser helps you build, organise and navigate within your model.

Line type data form

OrcaFlex line properties are input on this form. Similar input forms are used for other data.

Results selection

OrcaFlex presents a wide selection of results. Once a calculation is complete you use the results selection form to choose which results to view.

Results output

OrcaFlex results output is available in graphical or tabular form. Above is a graph of tension plotted against simulation time, together with the same information in tabular form. The tables can be saved as Excel spreadsheets.

Variable data

OrcaFlex includes a powerful, general purpose framework for specifying variable data. This example demonstrates modelling of drag amplification due to VIV response.

Batch processing

The batch facility allows multiple analyses to be performed unattended. Here a set of load cases are being analysed on a 4-core machine. OrcaFlex runs jobs in parallel to extract maximum utilisation from the multi-processor machine.

Fatigue analysis

The integrated fatigue analysis module can perform a wide variety of fatigue calculations and makes full use of modern multi-core machines to extract maximum performance.

Modal analysis

The integrated modal analysis module calculates undamped natural modes for OrcaFlex lines.
