‘In‐situ’ internal pipeline cleaning, heating and coating services in the North Sea

Abstract

Pipeline Induction Heat (PIH), on behalf of Kestrel Subsea (main contractors to Occidental Petroleum (Caledonia Ltd.), recently completed a contract to internally clean and coat 17.6 kilometres of 6in and 10in diameter pipes. These pipelines may carry a mix of crude oil and corrosive gas at elevated temperatures, and therefore were internally protected against corrosion. The project was the first of its kind in the North Sea and combined the application of a cold cure liquid epoxy paint with a novel PIH‐designed electrical heating system, which ensured that the entire 17.6 kilo‐metre length of pipeline was maintained at acceptable temperatures throughout the cleaning and coating operations. This not only aided chemical cleaning but also ensured a rapid and satisfactory cure for the coating.
