ALE uses unique skidding techniques for Korchagin topside in Russia

« Back to news

Overview

ALE has used a unique offshore skidding technique for the first time to assist with the offshore installation of the satellite platform (SP) topside, weighing 2,565t, for the Korchagin oil field development project in Russia.

ALE was contracted to perform the engineering, weighing, jacking and load-out of the SP topside, as well as the mooring and ballast supervision for load-out for this project in Astrakhan.

The methodology involved skidding the topside transversally off the barge and onto a cantilever frame, then installing it using the traditional floatover method. Tolerances were carefully monitored throughout, with a retrieval system available for contingency purposes.

To control ALE’s skidding operation, the barge was kept with a positive heel at all times, so the skidding was always with a positive gradient to ensure any effects of free sliding were removed. To further mitigate this risk, ALE’s retrieval system was set-up to anchor the topside in position if required.

“This was not only a technically challenging project where we could find a smart and safer solution, but the short weather window also meant that we had to remain flexible. By deploying our specialists in offshore engineering, we could devise this unique solution and complete the manoeuvre safely and successfully.” explained David Le Masurier Project Engineer for ALE – Offshore Services.
