Este por ejemplo, es sobre los U-boot que operaban en el Oceano Indico, aunque está en ingliss,(sorri) pásale el traductor y te haces una idea...


Timetable for Overhaul
---------------------------

As far as possible (to avoid overexertion during the hottest hours of the day) working hours were confined to morning and late afternoon. The timetable for a boat in port was approximately the following:

After putting in to Penang or Batavia:

Some 3 days for cleaning out the boat, to withdraw and check the torpedoes.

SOme 20 days for urgent maintenance work and overhauling of the hull, diving fittings, engines, and weapons.

Some 3 days to stow away the supplies and transfer the boat to Singapore for docking.

Some 14 days in dock for cleaning and maintenance of the skin plating and repair of outer damage, for unloading and loading of the keel and fuel tanks, then transfer to the port of departure, Penang or Batavia.

Some 14 days for replenishing the boat with fuel oil, lubricating oil, provisions, and ammunition, for recreation of the crew, trial runs, and diving tests.

In practice, unexpected delays always occurred, which in most cases could be traced back to the vulnerability of the boats to the damp climate. The best time made for overhaul was 70 days.
----------

Fitting out of the boats for further operations or return passage constituted no great difficulties, except in obtaining lubricating oil. Torpedoes had been brought up by cargo carrying U-boats. Moreover the boats which arrived from patrol had not fired all their torpedoes. Stocks of torpedoes ere even increased as operational boats, when dispatched as cargo carriers, had to give up all their torpedoes except two. Generally, the ammunition was not used up and spare barrels for 3.7-cm. and 2-cm. antiaircraft guns were constantly brought in by all the boats. The radio location sets, which were particularly necessary, were immediately copied from the latest construction so far as was possible and they were also constantly supplied from Germany. Other important spare parts for engines, auxiliary engines, and radio sets, which were not to be found among the well-organized supplies, were made in own workshops or by the dockyards. For example, an inflexible snorkel was made and installed.

General equipment was supplied by the dockyards. Stores found after the occupation were sufficient for that purpose. With the assistance of the Japanese Army, the boats were smoothly supplied with provisions. The preparation of bread, fats, vegetables, and fruits as K-rations was the main problem for the German offices. However, after initial difficulties, it was partially solved by enlisting local canning factories.

Fuel oil and lubricating oil were supplied by the Japanese Navy. Fuel supplies were always assured because of the rich stocks in Seletar and on the islands of Java and SUmatra, and the oil fields in the Dutch East Indies, particularly Palikpapan. However, beginning with the summer of 1944, it became almost impossible to get any lubricating oil of the quality that the German U-boats required. Inferior qualities of oil had to be used and this meant more wear and tear on the bearings.

Pues al chapista. Chorreado de arena, pintura con minio, Alberich si se tercia, barniz para cubierta y arreando.

Lo que no se - y ahí si que me gustaría que me dijera algo Kamez - es si se usaban rayos X para comprobar las soldaduras. Porque entonces era todo a base de soplete. Y sopletes laser como que no.
