Introduction

This recommended practice (RP) gives guidance for modelling, analysis and prediction of environmental conditions as well guidance for calculating environmental loads acting on structures. The loads are limited to those due to wind, wave and current. The RP is based on state of the art within modelling and analysis of environmental conditions and loads and technical developments in recent research and development projects, as well as design experience from recent and ongoing projects.

The basic principles applied in this RP are in agreement with the most recognized rules and reflect industry practice and latest research.

Guidance on environmental conditions is given in Sec.2, Sec.3 and Sec.4, while guidance on the calculation of environmental loads is given in Sec.5, Sec.6, Sec.7, Sec.8 and Sec.9. Hydrodynamic model testing is covered in Sec.10.
