Now less tired, and simply in need of a good weekend, so:
The runway is a Code 2 runway, maximum value for the greater of TODA or ASDA 1200m, as the width of the runway strip is less than 150m (150m would take it out over the docks and one requirement of the runway strip is that it must be load-bearing). It is greater than 75m, which is the requirement for a Code 2 instrument runway.
It's all in CAP168.
