After I left deep sea I ventured into the oil rig support industry. I was very fortunate to be posted to the Gabon where the sea is almost always calm. Do you know if there any photos of these supply boats in the gallery? I had a happy time on these vessels. I once remember having lunch and thinking I was in Kings Cross Station but one of the Offshore Marine boats had come alongside, she was fitted with a twin crankshaft English Electric diesel, same as railway locos.
