Tankers With Clean/dirty Oil and Spare Decks
Before the age of specialised supertankers the vessels could take "clean" oil, "dirty" - or change between them. The "clean" oil would be refined, as gasoline, while "dirty" was unrefined crude oil or heavy oil. A vessel only carrying "clean" oil would deteriorate faster, and so it was an ongoing fight from both Nortraship offices to get as many "dirty" cargoes as possible. Nortraship had a tough adversary in the British Ministry of War Transport as they produced statistics showing that British vessels were carrying more "clean" cargoes than the Norwegian. The US War Shipping Administration were more accommodating in this issue and let several Norwegian vessels change to "dirty" cargoes.
In peacetime it is very rare, if it happens at all, that a tanker takes deck cargo. The war changed this as there was a huge demand for transporting large pieces of war equipment from the US to Europe and other war theatres. It was quickly figured out that tankers had large uncluttered deck areas that could be used for volume cargoes, like airplanes and trucks. For this the tankers had to be equipped with so-called "spar decks" where the cargo could be secured. On 1 January 1944 a total of 58 Norwegian tankers were equipped to take deck cargo. The installation of the spar decks was paid for by the UK and Nortraship did not ask any payment for deck cargo, as the charter for the oil cargo already covered the costs.
