Torqueman,
they come $11 per man hour cheaper than JHAS (QF's figures not mine) and XMR's turn time was dictated by management and extensive sheetie work including keel beam change (among the many things the folk at JHAS or CHC do not seem to be geared up for).
All reports suggest that AAE are more than happy with the product. So much so that the other three freighters are coming to Tulla.
