Problems and prospects of offshore oil and gas pipelines construction

Abstract

An positives and drawbacks of existing methods laying deep-sea areas offshore pipelines (free dive
with long transportation pipeline sections (up to 10 km) to the place afloat conclusion, S and J-lay). For
laying of offshore pipelines Black and Azov seas, where maritime traffic is intense enough, the method of
O-laying. The necessity of installing cameras executing tools for diagnosing and offshore pipelines for
offshore platforms. The analysis technology construction of pipelines that can be used for laying pipelines
in the areas of coastline crossing seas, identified the advantages and disadvantages of each, highlighted
the main criteria and factors to be considered in their selection. Given scope, prospects and benefits of
technology microtunnelling, horizontal directional drilling used for the construction of underwater gas
and petroleum pipeline. Found that complications arise during the expansion of the scope and offered
constructive solutions to resolve these difficulties.
