Convoy PQ-4 consisted of eight merchant ships and they all reached North Russia after encountering heavy weather, but no enemy action. Also, it was the cruiser HMS BERWICK that escorted the convoy to Archangel and not HMS KENYA. Furthermore I'm not aware of any enemy attacks on the PQ/QP convoy series before PQ-7A in January 1942.

I also believe that the text was written by a seaman aboard the British freighter DAN-Y-BRYN. However, it seems to have been written from memories after the war as the details don't fit a certain convoy and probably describe events from different voyages. DAN-Y-BRYN made the Murmansk run four times: arrived in PQ-4 and returned in QP-4, arrived in PQ-14 and returned in QP-11, arrived in PQ-18 and returned in QP-15, arrived in JW-52 and returned in RA-53.
