The industry has been informed of this in new, identical letters issued on 22 February (see the link box).
Our letter emphasises that even though the current investigation of the Visund incident has not yet been completed, the investigation so far has provided clear indications that fatigue of the longitudinal welds between the side plates in the outlet system and the tank shell may be a contributing cause of the deflector plate having become deformed.
We are not aware of any similar incidents in connection with the flare systems for pressure relief from a processing plant, and through the identical letters etc. we want to make sure all relevant information from the Visund investigation is communicated to the rest of the industry as quickly as possible.
We would ask all operators to include this information in their current assessment of outlet systems.
