Bulk Storage Bins for Marine Application |

"A Analytic" designed the support structure for these two bulk solid storage containers. They are shown laying on their sides, loaded on trailer trucks for transport to the ship yard, where they were subsequently mounted to the deck of a well service barge that will operate in the Gulf of Mexico. To estimate the worst case loads on the structure due to wave impact on the barge, maximum wave data for the region of operation was obtained from the internet, and a differential equation (modeling the flow drag on the barge hull) was developed & numerically solved. Though, a Lloyd's of London specification was ultimately used for the design loads. These loads where then applied to a non-linear finite element model. The resulting stresses in the support structure were then used to perform a Weld Fatigue Analysis on the critical support joints. |
