Saipem has converted the former vessel “Maxita" into a fully redundant DP Heavy Lift vessel named “Saipem 3000” by replacing a completely new stern section and installing a CLYDE 76 model 2,400 st crane. The new configuration consists in a monohull unit with the following particulars: length 162 m, breatdh 38m and depth 9m, selfpropelled, with heavy lifting crane, associated to a DP system Class 3. The vessel will be suited for worldwide operations in the most severe environmental conditions.
The main crane (with relevant tub foundation) has been dismantled from the HLV named “Pearl Marine” and erected into the stern.
Main crane foundation has been integrated into the new structure on which two azimuthal and retractable thrusters for propulsion and for dynamic positioning are installed.
The A-frame of Clyde crane has been shortened in order to reduce our draft for passage through Suez Canal.
Furthermore existing accommodation and relevant systems have been upgraded to lodge 211 persons as per safety appliance. Converted vessel has dual classification: ABS and DNV.
