Let's back-up for a second.
Unfortunately I haven't followed the run up to this as closely as I should have, but perhaps someone could shed some light on this.
If I understand it correctly, there are 2 contracts to be bid for, one for new combat vessels, one for icebreakers and a support ship, and possibly a third for smaller vessels. Now, the three shipyards (or lead groups) are bidding each contract separately, knowing that they will get one of the two big contracts, or possibly the smaller third contract as a consolation prize, with the other main contract automatically going to the other winning lead group.
Now here is an interesting scenario according to the previous article: is it possible that since only two people in the country may know which group will win on each given contract, and neither knows the result of the other that it could result in one lead group "winning" both? Wouldn't it then come down to the "winner" being given the choice of which contract they would rather have?
