“…In other test conditions, Chan and Melville (1988) measured values of α between 3 and 10, whilst field measurements on seawalls by Blackmore and Hewson (1984) suggest α to vary between 0.5 and 4. Suchithra and Koola (1995) performed model tests to measure vertical forces on a horizontal slab. They tested different configurations (with and without stiffeners) to investigate the influence of down-stand beams on wave-induced loading.…”

“…A good comparison between the numerical and the experimental results was obtained. Suchithra and Koola (1995) carried out studies on the impact loads acting on horizontal slabs during wave slamming and concluded that wave slamming coefficient (C S ) depends on the air entrapped between the deck and the water surface. Howarth et al (2004) modified the studies done by MSL Engineering Ltd. (2001) to include the dynamic behaviour during the slamming of deck but concluded that vertical forces developed in the deck are mainly due to buoyant forces and the response of the jack-up structure towards the loads was static.…”

The offshore platforms are generally designed with sufficient vertical clearance from the maximum predicted wave crest elevations. This vertical clearance is termed as 'air gap'. However, due to compelling reasons of hydrocarbon processes and also due to the increase in water levels due to climatic changes or seabed subsidence due to reservoir subsidence, the lower decks may become vulnerable to wave action due to reduction in air gap. The structural elements in the lower decks may become prone to wave-induced loads caused by high wave crests. The assessment of such wave-induced loads on the lower deck and supporting structures, especially in the existing platforms, becomes very essential for the continued safe operations. In the case of wave slamming on a structure, these supporting structural members will also be prone to large loads. Circular sections are commonly used for substructures due to their hydrodynamic efficiency; however, for deck structure, it is very common to use non-circular sections for supporting superstructure loads. The non-circular sections used in the lower decks get exposed to wave-induced loads. The imposed loads could be of higher magnitude compared with the circular sections due to the flat surface of the sections. A review of the literature indicates that the previous studies focused mainly on the circular sections and not much information is available on the non-circular shapes, especially in the case of wave slam and slap. The current study was focused on the measurement of wave-induced slam and slap loads on an array of non-circular sections in a laboratory wave flume and the estimation of force coefficient based on drag-based empirical equations. The studies revealed that the slam and slap coefficients for non-circular shapes are greater than those for circular shapes.

“…Shoji and Moriyama (2007) investigated the characteristics of the wave force acting on a bridge and the stability of the bridge. The characteristics of the wave force acting on bridge beams are partly similar to that acting on pier deck, which have been investigated by many researchers, e.g., Tanimoto et al (1978), Kaplan and Silbert (1976), Suchithra and Koola (1995) and Cuomo et al (2007).…”

The applicability of the existing prediction methods of the wave force acting on a horizontal plate above the still water level is investigated by comparing the estimated wave force with the measured wave force. The applicability of a numerical model as well as the equations from experimental results is investigated. Some prediction methods overestimate the measured wave force, and some prediction methods underestimate the measured wave force.
