... operations. When the surface ship changes speed, differences in the normal component of the velocity along the cable are present because of time delays in the response of the bottom of the cable to inputs at the top. The longer the cable, the greater are the delays. This creates large velocity gradients...

... are largely independent of water depth. The essential platform element is a buoyant tower structure which is restrained at the base by a stiff mooring system. Three (3) basic applications have been identified for the SMAC structure. These are: SMAC Production, where the SMAC structure operates as a wellhead...

INTRODUCTION One of the possible ways to improve the performance of footings of gravity offshore platforms is the installation of additional ribbed elements – "skirts". Their height (the depth of penetration) is determined by many factors, such as the installed...
