MARIN offers a wide selection of papers and doctoral theses in the field of hydrodynamics on its website at www.marin.nl/publications.


The most recent publications include:


Validation of CFD simulations of the moored DeepCwind offshore wind semisubmersible in irregular waves Wang, L., Robertson, A., Kim, J., Jang, H., Shen, Z., Koop, A., Bunnik, T., Yu, K. Ocean Engineering, Volume 260, September 15, 2022

Two EU grants for next- generation floating solar plants


Within the EU’s HORIZON Research and Innovation Actions, MARIN is partnering up to work on the next generation of floating PV systems. Two proposals with MARIN involvement have been granted, both scheduled to be completed by early 2025. MARIN will lead the hydrodynamic assessment of wave and wind loads, as well as the validation of the integrated design.


The SUREWAVE proposal, led by SINTEF, aims to scale up floating PV installations for Baltic and North Sea conditions. The foreseen design integrates a modular floating PV field with floating breakwaters that create shelter against wave action. The project further explores the use of re-usable concrete materials and includes an integrated lifecycle sustainability assessment of several design variations in order to minimise the environmental impact. www.marin.nl/jips/surewave


The NATURSEA-PV proposal, led by Tecnalia, aims to improve the overall lifetime, reliability and maintainability of supporting structures for offshore floating PV. This considers the possible redesign of the substructure, taking the harsh conditions of the open sea into account, and the need to ensure durability with minimum construction and maintenance costs. Just like the SUREWAVE proposal, NATURSEA-PV also looks at concrete. A new eco-UHPC will be used as an alternative to the ubiquitous HDPE (High Density Poly Ethylene) commonly used in calmer inland waters. www.marin.nl/jips/natursea-pv


WINDLASS JIP concludes in time for new storm season in ports


After measuring 3D wind fields, moored vessel motions and line loads in five major ports for three years, the WINDLASS JIP has concluded in time for the next storm season. The measured data contributed to the crucial development of wind loads on container vessels and cruise ships in port. Besides


advanced CFD modelling and Dynamic Mooring Analysis, a practical wind load computational model has been developed. The WINDLASS tool is now being used by the participating port authorities, pilots, linesmen and engineering contractors. For more information, please visit www.marin.nl/jips/windlass.


New VOF chairman


A new chairman of the Vessel Operator Forum (VOF) was appointed, due to the retirement of Henk van den Boom, who established the VOF in 2007. The legacy will be continued by Patrick Hooijmans, Team leader of the Transport and Shipping team. The VOF will continue its valuable research into better ships from both a safety and economic point of view. These topics are the focus of the ongoing JIPs TopTier and F-series propellers. New initiatives will be launched during the upcoming meeting on December 7 and 8. For more information: www.vesseloperatorforum.com
