During a panel discussion at the Shipping 2015 conference in Stamford Ole Hjertaker noted that the tycoon carries a copy of an industry almanac published by the Norwegian Shipowner’s Association.

While this isn’t a particularly groundbreaking revelation the executive told the audience that the copy in question is indeed unique in that it was printed over 40 years ago.

Hjertaker’s testimonial came during a question-and-answer session in which a delegate asked panelists whether they ever rely on historic cycles as a point of reference when producing market forecasts and timing the deployment of capital.
