O.k. I assume that by referring to yourself as a person with "years of experience" in the offshore oil and gas industry, you are saying you work for BP. Is this correct? You have talked with one [unidentified] "authoritative" person who were present and is not a journalist. In other words, someone who may have directly caused the incident has assured you it was not his/her fault. And I assume the reason this individual cannot be identified because he/she is a likely witness in litigation and potentially liable.
Is that a fair summary of what you are saying, or have I missed something? If this is what you are saying, your story does not inspire confidence.
