Introduction

Considering the surrounding environmental condition at each project location is an important aspect in any offshore development project, environmental data are usually gathered through surveys as visual surveys by divers or ROV, seabed condition and profile data in geophysical surveys, wind, current and wave data in oceanography, soil properties in geotechnical surveys. Surveys are also used during construction for construction support and after that in inspection services.

In the marine environment, wind, currents and waves (meteorology and oceanography) exist due to natural phenomenon as (earth rotation, temperature, salinity…). These natural effects generate hydrodynamic forces which under adverse conditions can be capable of compromising the integrity of the structure or the pipeline. Extensive wind, wave and current data can be obtained from recognized agencies depending on the location, others might require a survey. Data sets obtained can be considered reliable if obtained for at least the previous five years.
