Transneft Druzhba has completed revamping of ten underwater crossings of petroleum products trunk pipelines (PPTP) in Bryansk, Tambov and Penza Regions. The total length of the revamped pipelines, taking into account bank sections, exceeds 6.5 km.
The planned works were launched in February as part of the company’s technical upgrading, revamping and overhaul programme. The goal was to maintain a high level of industrial and environmental safety of the diesel fuel transportation.
The revamping of the underwater crossings of the Section No. 42 PPTP through the Prud small watercourse in Unecha District and the Titva small watercourse in the Starodubsky District of Bryansk Region.
The underwater crossings of the Ufa – West PPTP via the Rozhok River in Pochepsky District of Bryansk Region, the Malaya Yaroslavka River in Nikiforovsky District, the Bolshoi Lomovis and Maly Lomovis Rivers in Bondarsky District of Tambov Region, the Oryev River in Bashmakovsky District of Penza Region were revamped. In addition, the section of the Penza – Saransk PPTP via the Kostylyayka River was revamped in Issinsky District of Penza Region.
Also, the underwater crossings of the Kuybyshev – Bryansk PPTP across the Sestrenka River into the Goritovka River in Michurinsky and Petrovsky Districts of Tambov Region was also revamped.
The new PPTP sections were laid in parallel with the existing ones without interruption of petroleum products transportation. The need for revamping was caused by increased requirements for the reliability of pipes running through waterbodies.
Commissioning works were performed at all the revamped underwater crossings, and the operation of telemechanics and automation systems was tested. The works were carried out in strict compliance with environmental legislation and environmental standards.
The revamped underwater crossings were commissioned. Sections for which they were built will be dismantled.
By the end of the year, it is also planned to commission two more underwater crossings of Transneft Druzhba’s trunk pipelines
