The original budget for these vessels was set in a rather different time and place. For one, NSPS wasn't contemplated at the time, so the question of what a fisheries science vessel would cost was kind of using commercial comparators. I don't think they were the right comparators.
Second, those initial budgets didn't take several key things into account. They didn't account for inflation. If you have a delay in building the ship, a gap develops between the budget you set and the actual price for the ship, because inflation kicks in, and marine sector inflation tends to run hotter than general inflation.
Third, we know that some specific costs that are required for a shipbuilding project weren't included in those old numbers. Without getting too technical, warranties, for example, were not costed in. Engineering wasn't costed in. Insurance during the build process wasn't costed in. No matter where you build your ship or when you build your ship, you'll have some other costs within your project management that were never reflected in those budgets.
Our costing internally is significantly more robust than it was in 2005 or 2006. In fact we don't use the words “cost overrun”. That may sound a little defensive, but we actually think of it in terms of properly setting the budgets at this time. We're trying to take a comprehensive view of what the project costs to run. We're taking a comprehensive view of the impact of commodity prices, inflation, currency fluctuations. We're definitely working towards costing on those vessels that's in a completely different league in terms of its reliability from the original numbers.
