What are the rulings on worship such as prayer, ablution and Friday prayer for crane operators at the North Butterworth Container Terminal?

Summary

Crane operators remain obliged to pray, fulfilling the conditions and pillars as far as they are able, and their difficulty is regarded as masyaqqah. A obligatory prayer performed without facing the qibla in the crane need not be made up, praying in shoes is permitted if they are free of impurity, and second-shift workers may combine Asr with Zuhr early and Maghrib with Isha late. Missing Friday prayer is permitted only if the duty cannot be handed to someone else, a rotation is used where possible, and Zuhr prayer is performed after the shift ends.
