Annotation: The article deals with issues concerning the stress-strain state (SSS) of a continuous transportmounting frame (СTMF) elements while transporting separate offshore platform structures in the process of offshore field development. The field, named after Vladimir Filanovsky is the largest oil reserve field discovered in Russia during the past 10 years. In 2013 77 km of submarine pipeline external oil transportation and 61 km of submarine pipeline and 40 km interfield pipeline and 40 kilometers of the pipeline were built, which bind them to the Filanovsky field and Yuri Korchagin field. One of the waterworks is ice-resistant steel platform (LSP). The given construction represents two steel support blocks of interconnected multitiered steel deck. Topsides will be installed on support bases in 2014. Deck construction is performed on the shipyard in Astrakhan and the further transportation to maintenance site demands specific steel construction – CTMF, which will allow transportation of multilayer steel deck on the barge point arrangement. SSS research data of CTMF elements for multilayer steel deck of ice-resistance steel offshore platform (ISOP) are given in the work. CTMF represents the system of cross heavy steel trusses. Dimensional model of the «multi-layer steel deck – Continuous cutting transport – mounting frame» has been developed. One has investigated element SSS of the dimensional model under load for a period liner and install deck on CTMF, removing of CTMF with the deck on the building site prior to loading onto the barge, CTMF placing with deck attached to it on a barge and during transport on the river and the sea under recommended normalized wave loads. The results of SSS numerical studies of CTMF elements are given.
Keywords: multilayer steel deck, ice-resistant steel offshore platform (ISOP), continuous transport-mounting frame (СTMF), finite element, finite-element method, design model.
