At the end of the 80s, a collaboration programm began between Bazan company of Spain and NEVESBU company of Netherlands. They started a program to build a Replenishment Oiler type logistic support vessel (AOR) for both Navies. This collaboration resulted in the Spanish Navy’s A-14 Patiño, and the Dutch Navy’s A-836 Amsterdam. The A-14 Patiño was commissioned on June 16, 1995, only 2 years after its construction began. It is a vessel designed to supply a naval combat group, including aircraft carriers. For this task it has a cargo capacity of more than 9,000 tons of fuel, and various solids stores as food, ammunition and spare parts. The ship was built in MS steel type with a production standard for civilian merchant ships according to Lloyd’s Register regulations. However, the ship was equipped with a military communications system. The ship has 5 supply stations for liquids, two in each band and one aft. There are six other supply stations for solids, and a flight deck aft that allows VERTREP, (vertical replenishment), operations through helicopters. Since its entry into service, the A-14 Patiño has participated in many international peacekeeping missions and surveillance against piracy in the Horn of Africa.
