JACKING SYSTEM
The invention relates to a jacking system for jacking a structure, in particular for jacking offshore platforms or vessels out of the water, said jacking system comprising a leg having a longitudinal axis and comprising first engagement parts along said leg, and a guiding frame displaceable along said leg, said guiding frame comprising at least a first, second, third and fourth actuator, said actuators each having a first and second actuator part which in operation can displace with respect to one another along said leg, said first actuator part of said actuators coupled to said guiding frame, said second actuator parts of s aid actuators each coupled to first engagement parts for engaging and disengaging said first engagement parts of said leg for providing abutment in the longitudinal direction of said leg, said second actuator parts of said actuators displaceable along said leg past one another, and said actuators being arranged in pairs opposite one another with respect to a longitudinal plane of said leg. This jacking system provides a faster jacking of for instance vessels for offshore construction.
