Icebreaker WIP

I'm currently building a kinda (trans light blue is expensive!) large antarctic layout with an expedition being droped off at the edge of an ice shelf. The ship will feature a portal crane at the stern (up/down) and two "normal" ones (crane turn left/right and boom up/down), one midships and one at the bow.

This is my first time using technic gears power functions in a MOC, so if you spot something needlessly complicated or unsuited for longer durations of operation please tell me!
