Mr. Paul Mulvaney:

Absolutely. There are pressure gauges and head tanks. The oil is in head tanks on either end of the cable and there are pressure gauges, so we can monitor the level of the oil. It fluctuates up and down as the cable heats up and cools down as it is loaded, but we know if there is a leak based on that. Once we have a leak we then have to find it. I went through the procedure as to how we find the leak, which can be an arduous procedure. It is possible to repair the cable. The cable is not damaged permanently, and it can be repaired. The troublesome ones, on a risk basis, are being changed out.
