The present paper summarizes methods of estimating wave effects on offshore structures, and highlights a selection of recent related research. Initially, certain aspects relating to the...

Probability of Wave Force on Horizontal Members
This study is motivated by the works of Isaacson and Subbiah (1990) to evaluate the vertical wave force on a rigid horizontal member located in the vicinity of still water level with its...

Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...

Static Wave Force Procedure for Platform Design
Since results from the Ocean Test Structure were presented at Civil Engineering in the Oceans IV in 1979, there have been numerous laboratory experiments and a few full-scale measurements...

Wave Slamming on a Horizontal Circular Cylinder
The present paper describes an experimental study of the wave slamming force on a horizontal circular cylinder located near the free surface. The vertical force on a cylinder and the corresponding...

Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...

Experimental Research on Groyne Stability Under Very Oblique Wave Action
Most of the experimental research concerning the stability of coastal structures is focused on normal wave incidence. However, many of these structures are subject to waves which run predominantly...

Safety Factors, Loads, and Impact
The loads given in this chapter are intended for general guidance only (including wind, ice, stream flow, etc.). Maximum deflections and rotations may likewise vary with national codes....

Activities Aimed at Qualification of a HLW Disposal Container
A container is being developed for the permanent disposal of used fuel from CANDU nuclear reactors in a deep underground disposal vault. The container is required to isolate the fuel from...

Testing of Materials and Scale Models for Impact Limiters
Aluminum Honeycomb and Polyurethane foam specimens were tested to obtain experimental data on the material's behavior under different loading conditions. This paper reports...

GA-4/GA-9 Honeycomb Impact Limiter Tests and Analytical Model
General Atomics (GA) has a test program underway to obtain data on the behavior of a honeycomb impact limiter. The program includes testing of small samples to obtain basic information,...

Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...

Experiences with Military Installation Drainage Systems
