... Abstract This study describes the purpose, scope, and acceptance criteria for wind load assessments that are used in the Classification of offshore units and installations. Wind loadings are applied as external environmental forces when evaluating afloat stability, structural strength...

... Abstract Wind represents a driving factor for floating system designs, not only for stability, but also for platform global performance including offset, heel and airgap, and thus for mooring, riser/umbilical, structure, topsides equipment and personnel habitability. Wind load evolves...

... Abstract This paper documents the results from the 2017 Society of Naval Architects and Marine Engineers (SNAME) OC-8 Panel Comparative Wind Load Study. Initial unpublished results were presented at a one-day panel at the 2017 SNAME Maritime Convention; however, the final results are brought...

... Abstract This paper summarizes an on-going effort by SNAME OC-8 CFD Task Force to provide guidelines on wind-load estimation by CFD simulation. The intention of the guidelines is to help the industry to obtain reliable and accurate estimations of wind load on offshore floating facilities using...

... Abstract Wind loads represent an important contribution to the design loads of large floating offshore structures during installation, normal operation and in extreme conditions. It impacts the intact stability of the floating structure as well as its mooring loads. In many cases the wind loads...

... application. Introduction Wind can induce large drag forces on offshore structures. Most often the wind load does not dominate over the wave load in the extreme design condition. In the case of fixed jackets, the wind generates a small fraction, order ten per cent, of the total extreme load and the draft ISO...

... investigation was performed in support of the HARMONY and HERITAGE transpacific jacket tows. This study provided wind load mea- surements for use in establishing towing vessel requirements, and assessing hydrostatic stabili- ty of the barge tows. In conducting the wind tunne1 experiments, the jacket models were...

To gain a better understanding of the wind loads on guyed tower structures, a wind tunnel test was performed...

... Abstract Since mobile offshore platforms must operate as seagoing vessels as well as elevated platforms, the wind loads play an important role in their design. The objective of this work was to generalize the windoad design procedure and to determine the unique features of the mobile offshore...
