Modelling the waterjet cable trenching process on sand dunes

Cables for offshore wind farms in the North Sea are buried for protection. A highly variable seabed topography influences the trenching process in sandy soils. A model has been developed to estimate the influence of sand dunes on the trenching process.

“Facts About Seabed Intervention” describes how dredging performs the crucial task of preparing the seabed for offshore installations and pipelines.

Calculations on Forces and Velocities of a Submarine Narrow Trench Plough in Sandy Soil

Demand for submarine cables for exporting the energy from wind farms to shore is increasing. To prevent damage to the cables when exposed on the sea bed, adequate protection is critical, but current calculation methods are usually empirically extrapolated. To better predict towing forces, a new calculation method is given.
