N2 - Long term distributions of environmental loading are determined for generic jacket, jack-up and monopod "minimum facilities" platforms. Australian North West Shelf met-ocean data are used, with both shallow (40 m) and moderate (90 m) water depths. Global (system) loads are related to the critical local (component) forces that trigger structural collapse. The various distributions are quantified and compared in terms of the wave height exponent alpha. It is demonstrated why base shear is a good measure of the critical environmental load for typical jackets. However, this is not the case for other structural configurations due to non-proportionality of the loading, which is accentuated in shallow water. As a result, monopods in particular may be expected to have considerably lower structural reliability than jackets when designed to the same Code. (C) 2002 Elsevier Science Ltd. All rights reserved.
