摘要
A platform is raised from water level up to the tops of prepositioned template legs by means of jacking units comprising jacking mechanisms and jacking legs mounted near the upper ends of the template legs and extending down to the platform. Bridge beams of open framework construction span the distances between the upper ends of the template legs and these bridge beams provide support for the jacking units as well as reinforcement for the platform when it has been raised.
