MoorDyn, an open-source mooring model

segments

 

MoorDyn is a lumped-mass mooring line model designed for easy coupling with other software (i.e. floating platform models). It supports arbitrary line interconnections, clump weights and floats, and different line properties. The model accounts for internal axial stiffness and damping forces, weight and buoyancy forces, hydrodynamic forces from Morison’s equation, and vertical spring-damper forces from contact with the seabed.

The original version is written in C++ and has been successfully coupled with FAST v7 and other tools/models in Matlab and Simulink. A separate Fortran-based version has recently been incorporated into FAST v8 (nwtc.nrel.gov/FAST8). More information and downloads can be found at www.matt-hall.ca/software/moordyn.

turbinesFOAM

turbinesFoam is a library for simulating wind and marine hydrokinetic turbines in OpenFOAM (2.3.x). Some components for solvers and turbine models have been taken from NREL’s SOWFA and Offwind.

Get it on GitHub: github.com/turbinesFoam/turbinesFoam

This library is in heavy development and is not yet fully functional, but pull requests are encouraged!

Marine Renewable Energy Knowledge Exchange

textlogo

The UK Natural Environment Research Council (NERC) has developed a Marine Renewable Energy Knowledge Exchange Programme that provides a wealth of valuable and well-organized information. On the existing (and ever-developing) programme portal, you will find:

  • An events calendar, which relays information on marine renewable energy events.
  • A funding page that highlights all funding opportunities that could be relevant to people in the sector. When new items are added, alerts will be tweeted, so follow @MREKEP on Twitter. The programme can also directly fund certain small projects and internships.
  • Literature – papers, reports and more. There is a huge library of links – it is searchable and growing! Anyone can submit entries to be added to this collection by e-mailing mrekep@nerc.ac.uk
  • Images – It can be tough to source relevant pictures for work such as web content. The site is working to build up a collection that anyone can use as long as they credit the photographer. Feel free to add to it.
  • Research – There is also the beginning of a database of ongoing research in the field.

The NERC MREKEP portal is really excellent. Take a minute to check out the site:
