ProteusDS Update December 2023
We’re excited to announce that ProteusDS v2.66 is available and can be downloaded now! There are many enhancements in this version, including new seakeeping features, plotting improvements, and support for multiple current profiles in the Oceanographic Designer application. Read on for more details.
Introducing ship seakeeping and maneuvering capabilities
You can now conduct seakeeping and maneuvering analysis with ProteusDS. ShipMo3D is DSA Ocean’s seakeeping and maneuvering software. It was previously available as a separate installer and subscription from ProteusDS. But we’ve now simplified things. ShipMo3D is now available as an add-on toolset for ProteusDS. By including ShipMo3D with ProteusDS, in a single installer and software application, it enables more integrated functionality and workflows. For existing ProteusDS users, it means that you can now conduct ship seakeeping and maneuvering studies with ProteusDS when you subscribe to the ShipMo3D toolset. All related ShipMo3D documentation and sample projects are now available on the ProteusDS Documentation page here.
Visualize vessel motion in ProteusDS
For existing ShipMo3D subscribers, there are new features that are available now that the ShipMo3D applications are installed alongside ProteusDS. Using the motion RAO output from ShipMo3D, the resulting vessel and sea state can be visualized in 3D via a ProteusDS simulation. This powerful new visualization capability is a great tool for understanding vessel seakeeping capabilities.
Calculate a hydrodynamic database for a vessel or barge
Vessel and barge mooring analysis often requires wave radiation and diffraction effects. The ShipMo3D toolset in ProteusDS now gives our subscribers a streamlined option to calculate these parameters and incorporate them into their simulations, better-resolving wave loads and mooring system responses.
Accelerate new mooring design in Oceanographic Designer
For our Oceanographic toolset users, we’ve added a few small steps when starting a new project. With clarity on the intent of the design – a surface or subsurface mooring – you will have a few components automatically generated to get you going.
You can also now store the Lat/Long location of the mooring with your mooring design parameters and visualize its location in Google Maps. You can also import the location from Google Earth.
Define multiple current profiles in the Oceanographic Designer
We added the capability to specify more than one environmental load case in Oceanographic Designer. This makes it far easier to generate more than one simulation scenario, each with different current profiles and wave conditions. It makes it easier to track all of the load cases you want to run for a given mooring design.
Plot multiple cable tensions
For users working with multi-leg mooring systems or simulating the response of more than one mooring system at a time, we’ve made it easier to digest and compare all of those simulation results. You can now plot tensions from multiple Cable objects on a single plot in PostPDS. In PostPDS, simply right-click and select Plot Tension and follow the options to superimpose the data series on a single figure.
Improved mooring layout and BOM report
As shown in the figure, we’ve significantly enhanced the mooring layout export from Oceanographic Designer. In addition to making the Excel file more readable, we’ve combined the mooring layout and bill of materials reports into a single Excel Workbook. This streamlines the export of construction data from the Oceanographic Designer into a single step.
New sample oceanographic mooring designs
Two new subsurface sample mooring files are now available courtesy of the Rosenstiel School of Marine and Atmospheric Sciences (RSMAS) and Woods Hole Oceanographic Institution. Note that the RSMAS M480C mooring has six current profiles configured with it that correspond to the conditions of an active research and development project on Vortex-Induced Vibration risk factors.
