Brinings were the agents for the Shell owned or Time Chartered Vessels both at Tranmere,Eastham,Stanlow and Ince for a great many years.
Eventually our firm was taken over by OBC Shipping who remain as the Shell Agents, sadly that was the time after about 2 years when I was made redundant i.e. 2001.
The pilots you referred to are John Megginson and I think his brother was called Charles Megginson. John was the senior pilot for Shell and is still alive, living near Chester.
