  • Unexpected Pressure in Structural Members

    Posted by Ian Charles on June 30, 2020 at 9:44 am


    I’m looking for any relevant experience relating to unexpected pressure and/or hydrocarbon presence in structural members during decom activities (jacket legs). I’m currently investigating such a case and would be interested to know whether there is experience and/or whether it is considered as a recognised hazard with operators and specialist service providers?

    All comments appreciated, once the case I’m involved with has better definition I will of course share any relevant findings or learnings.

    Hi Ian, hope all is well. Firstly, I think this is great that you have tried out the discussions forum and given this is one of our first discussions i would like to help you push it out to the ONEDECOM community to see if we can help you on your query?

    I personally have not come across any issues like this before, nor has it been captured for any steel jackets HAZID / ENVID’s we have discussed. Will be interesting to hear what responses you get.

    Out of curiosity, is this for a concrete gravity base or steel jacket?

      Thanks for response Colin, hope all is well with you too.

      It was an 8 leg steel jacket. Internal leg, internally piled and grouted. And as far as can be determined so far, with no flanged access points. But as you can appreciate, this information is not yet fully verified.

      Once I have firm, shareable data I’ll give you a call and share accordinglyl.

      Best regards,
