ABSTRACT:
A marine structure which includes a jack-up platform assembly having a platform and at least three support legs, each leg having a generally cylindrical adapter at a lower end thereof. A support assembly includes a receptacle for each of the support legs, the receptacle mating with the support leg adapter and supporting the platform assembly, enabling the platform to be jacked up above an ocean surface. A stop assembly is removably attached to each of the support legs, the stop assembly being spaced from the support leg adapter and including a stationary part which mechanically engages a portion of the receptacle when the support leg adapter penetrates a predetermined distance into the receptacle. The stop assembly is secured to the receptacle by pins extending through a part of the stop assembly and a part of the receptacle. The stationary part can be a cover attached to the support leg by racks engaging racks at the corners of the support leg or a horizontally extending annular base secured around the support leg by a framework including racks engaging the racks at the corners of the support leg.
