CAISSON BREAKWATER DESIGN FOR SLIDING
"... The offshore caisson breakwater at Costa Azul installed in 25m water depth is designed to withstand Pacific swell waves up to a PLS test case Hs 9.2m Tp 18.6s. Overall stability design is in accordance with the recommendations of PIANC WG 28. The critical failure mechanism is sliding, and the caisso ..."

, and the caisson base is cast with a deliberately roughened (serrated) profile to increase sliding resistance and optimize the caisson cross section. Site based testing at prototype scale was conducted to validate the coefficient of friction used for design between the caisson base and nominal 100mm single size
Impedance of flexible suction caissons
"... The dynamic response of offshore wind turbines is affected by the properties of the foundation and the subsoil. The aim of this paper is to evaluate the dynamic soil–structure interaction of suction caissons for offshore wind turbines. The investigations include evaluation of the vertical and couple ..."

Interaction of Forces on Caissons in Undrained Soils
"... In this paper the results of a numerical study on the behaviour of caisson foundations subjected to various combinations of loading are presented. A typical caisson has been used in this study with a length-to-diameter ratio of 2. The caisson is assumed to be embedded in a homogeneous soil deforming ..."

HYDRODYNAMIC EFFICIENCY OF PARTIALLY IMMERSED CAISSONS SUPPORTED ON PILES
"... The efficiency of the new type breakwater, which consists of caissons supporting on the two or three rows of piles was studied using physical models. The efficiency of the breakwater is presented as a function of the transmission, the reflection and the wave energy loss coefficients. Regular waves w ..."

Tensile loading of model caisson foundations for structures on sand
- Proc. ISOPE, Toulon
, 2004
"... The viability of multiple footing structures that use suction caisson foundations would be improved if the up-wind leg(s) could resist significant tensile loads. In the particular case of offshore wind turbines, large moments are applied at foundation level by the action of wind and waves on the str ..."

CHAPTER 200 WAVE IMPULSE PREDICTION FOR CAISSON DESIGN
"... Problems associated with the measurement of wave impact pressures are described and the poor comparison between the results of previous studies is outlined. It is argued that the force impulse form and magnitude are more relevant parameters for caisson design than maximum impact pressures. Data from ..."

from small and large scale laboratory measurements are used to develop a simplified design approach for caisson breakwaters based on the limited magnitude of the force impulse. Comparison between large scale data and predictions based on small scale results show reasonable agreement.
WAVE IMPACTS ON VERTICAL SEAWALLS AND CAISSON BREAKWATERS
"... In most developed coastal areas, seawalls protect towns, road, rail and rural infrastructure against wave overtopping. Similar structures protect port installations worldwide, and may be used for cliff protection. When a large tidal excursion and severe environmental conditions concur to expose seaw ..."

Abstract HAZARD ANALYSIS OF DYNAMICALLY LOADED CAISSON BREAKWATERS
"... Probabilistic analysis, based on the final outcomes of the European research project PROVERBS, Oumeraci et al. 2000a, is applied to two example cases: Genoa Voltri main breakwater (Italy) and Easchel breakwater, a fictitious case combining Eastern Scheldt Storm Surge Barrier (the Netherlands) for th ..."
