La MICOPERI 7000 poi divenuta SAIPEM 7000 - La nave officina più grande e potente di tutto il mondo.

The Micoperi 7000 is a semi-submersible factory vessel equipped with two gigantic cranes with a capacity of 7,000 tons each; it can lift over 14,000 tons of weight. It is the largest and most powerful vessel of its kind in the world. The dedication of the workforce that made it possible to fulfill this commitment is now rightfully part of the history of Fincantieri di Monfalcone: after exactly two years of intense work, the 7000 was able to leave the Adriatic waters bound for Brazil, where it began its operations. Semi-submersible crane vessel built in 1987 (Laydown December 19, 1985, launch December 15, 1986, delivery December 15, 1987) diesel/electric propulsion, installed power 75,600 HP (50,600 kW) ? 8 propellers 9.5 knots lifting capacity 14,000 tons accommodations for 680 people Crew: 120 It is a semi-submersible factory vessel equipped with two gigantic cranes with a capacity of 7,000 tons each; it is the largest and most powerful unit of its kind in the world. The complexity of its construction and functional characteristics truly defies a limited description; Even briefly, the ship's general structure can be illustrated as consisting of two hulls, each 165 meters long and 33 meters wide, each surmounted by three columns and a 175-meter-long platform, plus the structures for lifeboats, for a maximum overall length of 190 meters and a maximum width of 87 meters. The accommodation tower, located in the aft section, consists of five decks surmounted by the bridgehouse and the helipad, and can accommodate 800 people. The two gigantic cranes, mounted on two 28-meter diameter pylons in the forward section of the ship, reach a height of over 75 meters from the deck, with a 140-meter jib equipped with four hooks. Gigantism seems to be the general measurement module of the ship and its equipment. Sixteen 40-ton anchors, each fixed to 96 mm diameter cables and 3,550 metres long, ensure the vessel is positioned using winches of unprecedented dimensions (ten metres long, six metres wide and as many metres high); a ballast system based on four electric pumps with a capacity of 6,000 cubic meters/hour each, with one-meter diameter manifolds connected to the tanks that regulate the trim and immersion of the ship (of these, fourteen are intended for rapid ballasting with sea cocks equipped with butterfly valves each two meters in diameter: all controlled and regulated by a computer through a remote control system for the valves and machinery). The propulsion, cranes and all on-board systems are powered by electric motors, powered by a power plant composed of eight 5,500 kW diesel-alternators, two 2,800 kW and an 1,100 kW emergency generator, for a total of 50,600 kW. The ship is equipped with all the comforts for those on board, including a large indoor swimming pool, a sauna, a gym, recreation rooms, canteens and two cinemas as well as, of course, cabins with private bathrooms. to the complete air conditioning system and large service areas and changing rooms. During the tests carried out in the Adriatic, the MICOPERI 7000 passed all the tests and managed to lift, with the two cranes in tandem, 14,600 tons.
