Assessment of Ice Accretion on Offshore Structures
The literature on sea spray (superstructure) icing is almost entirely based on observations on moving ships. However, icing on stationary offshore platforms with their fixed vertical columns will differ significantly from ship icing, which is influenced by ship movement and wind and wave directions....

The literature on sea spray (superstructure) icing is almost entirely based on observations on moving ships.

Atmospheric icing may be a source of ice accretion on derricks in some locations, and the best commercial device currently available for measuring it is the Rosemount detector.
