Helideck study

The objective of a helideck study is to ensure that the flight conditions are adequate and in compliance with relevant standards. This means assuring that vertical velocity , turbulence level and temperature gradients are within accseptable limits. A helideck study would typically involve the following tasks:

Establish a realistic geometry model of the installation. This is important to be able to take into account the local wind flow patterns in the areas of interest.
Run a set of FLACS ventilation simulations in order to asess vertical flow velocities and turbulence above and around the helideck.
Run a few dispersion simulations with hot exhaust releases to assess possible temperature gradients above the helideck.
Results from a helideck study typically include 2D or 3D graphical plots of flow fileds , vertical velocity components, turbulence levels, and temperature.
Evaluate the results against any specified requirements or regulations.

Oil and gas operators need to place an even greater emphasis on safety in the design of oil and gas facilities to safeguard against explosion accidents, according to Dr Madhat Abdel-jawad, President of GexCon Australia.
