The technico-economic optimization of pipeline coatings is a permanent concern for petroleum companies. From this point of view, laboratory comparative tests are very useful but cannot replace the experience acquired in the field. The performances of various kinds of coatings used to protect buried pipelines and offshore pipelines and risers are presented through case histories experienced by the authors' company. Bituminous enamels, tapes and heat shrinkable sleeves, polyethylene, fusion bonded epoxy, polyamide, polymer cement compounds, glassfiber reinforced epoxy and rubbers are the coating families considered. For each of them, the general behaviour and any failures or problems encountered are reviewed. This summary covers the coating operations, the pipeline installation and the pipeline service life.

The opinion of the author's company concerning current choices and future trends for pipeline coating selection is given in relationship with laying and operating conditions. As a complement, the question of internal coatings of pipelines is raised in the paper.
