We developed a technical expert witness report designed to establish the suitablity of a production vessel, originally designed for use in the UKCS, for Canadian waters. The brief was to establish if there where insurmontable technical difficulties in deploying a vessel, originally designed for the severe weather conditions of the North Sea, in the ice-infested and potentailly frozen waters offshore Newfoundland. The conclusion of the report was that while all technical difficulties could be overcome, the cost impact of making the changes to the particular vessels would be severe.
