... 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...

... ABSTRACT Operations related to construction and/or installation of engineering structures (here referred to as engineering operations) involve risk to the structures themselves. Although the probability of occurrence may be low, the economic consequences in case of failure will in most cases...

... operation and installation, respectively). 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...
