What would be involved is extensive training - precisely the sort that is currently lacking. Basically, they were already trying to helicopter in folks. The difficulty is that it's rather challenging. They need folk who are intimately familiar with the local water- and weather conditions - aka pilots. On top of that, they need folk who can precision-steer the vessel. This is hard due to tides, current, wind, waves. Moreover, the vessel is too big to stop or turn on a dime. Hence the need for training.
