The Handbook of Scour and Cable Protection Methods

The Handbook of Scour and Cable Protection methods is the result of a multi-year research programme performed as a Joint Industry Project with the contribution of over 20 industrial partners. This project was initiated from the observation that no good and generically applicable design formulae and guidelines exist to protect offshore structures against scour. Instead, there are various existing methods and concepts that lack a sound basis for design. To help decision makers select the most suitable and cost-effective scour protection method for each considered situation the Joint Industry Project Handbook Scour and Cable Protection Methods (JIP HaSPro) was initiated by Deltares. The consortium consists of a certifying body (DNV), utilities (Ørsted, RWE, Vattenfall, Scottish Power, EnBW, Shell, Equinor, Ocean Winds), suppliers (SPT Offshore, Mibau Stema, Airgroup Industries, NoRock, SSCS), engineering firms (COWI, Kajima) and installation contractors (DEME Group, Boskalis, Van Oord, Jan de Nul, Tideway). The goal of this project was to develop a clear, generic and science-based comparison between different scour protection methods. In this project existing methods (based on loose rock) are optimized and new innovative and eco-friendly scour mitigation methods are investigated (proof-of-concept) and made ready for offshore field tests. The resulting findings are presented in the Handbook of Scour and Cable Protections, which is publicly available viahttps://publications.deltares.nl/Deltares250.pdf. All underlying technical reports and experimental data are publicly available as well to stimulate further development and collaboration on scour protection design within both academia and industry.
