Gazprom starts construction on new offshore pipeline

Construction has started on the 900-km TurkStream pipeline that will supply the Turkish network with Russian gas.

The 900-km offshore section of the TurkStream twin pipeline will run from Anapa in Russia and will come onshore near the village of Kiyikoy, 100 km west of Istanbul.

From Kiyikoy, an onshore pipeline will be constructed to connect TurkStream to the existing network at Luleburgaz, where it will continue to Greek border.

TurkStream’s offshore section will travel 900 km through the Black Sea.

TrukStream announced on 7 May that Gazprom PAO had started construction on the offshore section in the Black Sea, near the Russian coast.

Allseas has been awarded the contract for the pipelaying for both strings, using its vessels the Audacia and Pioneering Spirit – the largest construction vessel in the world – to complete the work.

Audacia will also be used to pull the pipe through microtunnels, while the Pioneering Spirit will be used for the for the deep-water sections of the pipeline which reaches depths of up to 2.2 km.

Once completed, the twin pipeline will be the first 32-inch diameter system to be laid at depths of 2 km.

Allseas’ Pioneering Spirit is the largest construction vessel ever built.

“Today, we started the practical implementation of the TurkStream gas pipeline project: pipe-laying within the offshore section,” said Chairman of the Gazprom Management Committee Alexey Miller.

“By late 2019, our Turkish and European consumers will have a new, reliable source of Russian gas imports.”
