Wind and Current Loading

Wind and Current Loading

BMT Fluid Mechanics offers numerous capabilities in the field of wind and current loading, from wave assessment to physical model testing, planning and execution.

The prediction of wave loading is a key component of engineering design for offshore structures, either to determine design loads, or to calculate resulting vessel motions.

Wind current loading sub 1BMT’s specialist knowledge and experience in numerical modelling of wave loads and vessel response, software development and physical model testing provides an unrivalled analysis and consultancy capability. BMT provides consultancy services to accurately determine wind and current loads in support of all stages of the design. Physical and numerical modeling techniques are used to provide vital input.
