Pipeline system "Eastern Siberia — Pacific ocean"

Pipeline system ESPO-1. In April, 2006 the main oil pipeline “Eastern Siberia-Pacific Ocean” (ESPO) was launched. This oil pipeline system was intended to be used for Russian regions of Far East and Asian-Pacific Region supply. They planned making of a technical connection to already existing Transneft’ LLC pipelines, that meant creating of a single pipeline system and timely hydrocarbon distribution both to the east direction and to the west direction. The first step of the infrastructure project (so called ESPO-1) was construction of a pipeline from Tayshet to Skovorodino passing through Amurskaya and Irkutskaya regions including Yakutiya. The mainline length is almost 2,700 km and its capacity is 30 MTPA. Simultaneously, oil loading port Kos’mino was commissioned, which was to feature capacity is 15 MTPA and seven pump stations (PSs.) Further pipeline expansion is planned to reach capacity of 80 MTPA by 2020. During construction, the builders faced various difficulties and applied comprehensive technical solutions. Thus, lack of any infrastructure at some areas stipulated usage track-all vehicles and helicopters to assess the pipeline location. Poor weather conditions (low temperature, seismic activity) and terrain features all way along the route (bogs, and boreal forest, and water obstacles.) Besides the main facilities the project included accompanying improvements made: new roads, waste treatment facilities, power transmission lines and required facilities were equipped with communication equipment and remote controls.

Construction of oil pipeline "Skovorodino – Chinese border"

In 2009-2010, Skovorodino - Chinese border" oil pipeline construction project was successfully implemented ; the project which is of great importance for the strengthening of friendly ties between Russia and China. The list of sites and facilities include linear pipeline portion lies along the Amur Region, crude oil transfer point at Dzhalinda village and Skovorodino oil pumping station. It was also necessary to provide process lines along the entire route during the construction period.

VELESSTROY participating in this project as a reliable partner with extensive experience in oil and gas construction, constructed the oil pipeline crossing point on the border between the two states. In just 4 months, the company has built a set of power units, household structures and the utilities. Specialists of "Velesstroy" conducted excavations and welding, mounted process equipment, automation objects and fire protection facilities.

Pump Station No 11

Pump Station No 11 is a standard pump station. As usual, VELESSTROY managed to cope with the normal extremities of locations such as remote from the main lands, lack of infrastructure, low temperature. Just on the very time we constructed main pump station, mud strainer, leakage accumulator tank and drain tank, electrical rack, diesel power plant, fire water pumping station, two fire water reserve tanks, electric lighting, communication system, radio equipment installation, structured cabling system, fire alarm, automation, on-site roads etc.

Pump Station No 12 with ADPP

Service of pump station No 12 complete with self-contained (autonomous) diesel power plant is increase pressure in the oil pipeline and make it up with crude. It is the spot that TAAS-Yrakha field is connected to ESPO pipeline system. On this site VELESSTROY has built not only the typical set of intermediate pump stations: main pump station, indoor switchgear, packaged transformer substation buildings, pipeline surge relief system, fire water facilities etc but also the building of autonomous diesel power plant which is run using crude oil.

Pump Station No 13

The site is located at 1 562nd km of the main oil pipeline ESPO-2. Totally, 80 units of special equipment and 550 construction men were involved on this site. Utilities cable rack is one of the most essential elements of the station which VELESSTROY constructed, this rack functions for remote controls and automation equipment. There is the line operations unit on the site which operates to the fullest extent, this unit services the line portion of the main pipeline. There are own fuelling stations, boiler rooms, three diesel power plants which are 24/7 available. Max cozy conditions were created on the construction site: comfortable living camps, dining area with actually porterhouse menu, sports and fitness room, recreation rooms, medical unit.

Pump Station No 14 with ADPP

“Olekminsk" oil pumping station of "ESPO" is a complex construction project, consisting of process, industrial, administrative and residential buildings, networks and lines. Critical factors of the project are not merely climatic conditions, soils and long-term freezing of a complete lack of transportation. VELESSTROY conducted complex works on the construction of buildings for shift workers, playgrounds and parks, pumping stations and reservoirs, installation of industrial pipelines and equipment installation.

 Yakutia is permafrost area.

PS 14 construction facility with ADPP is notable with all the foundations performed on piles, raising the building up to 1 meter high of the ground. Each pile has been paired with vertical heat stabilizers, which further supports the stability of the foundation. 

The specifics of the vertical heat stabilizer is that it collects cold in winter through the ribbed section of a heat stabilizer located on land that does not allow the upper layers of soil thaw in the summer. 8000 vertical heat stabilizers were installed. 

This project is very significant for Velesstroy that it has become the start for rapid growth of the company.

Pump Station No 15

Pump Station No 11 is a standard pump station. As usual, VELESSTROY managed to cope with the normal extremities of locations such as remote from the main lands, lack of infrastructure, low temperature. Just on the very time we constructed main pump station, mud strainer, leakage accumulator tank and drain tank, electrical rack, diesel power plant, fire water pumping station, two fire water reserve tanks, electric lighting, communication system, radio equipment installation, structured cabling system, fire alarm, automation, on-site roads etc.

Pump Station No 17

VELESSTROY acted was the general contractor in the construction of PS 7, located near the town of Aldan and that is a part of "ESPO" oil pipeline infrastructure. That was the first time when the company's specialists faced with such severe climate. The works were complicated by extremely low temperatures - up to -45˚С, but unlike Olekminsk, in this case near the construction site there were motor and railways, which greatly eased the supply procedure. VELESSTROY specialists conducted range of construction works: construction main pump building and household facility, the boiler room, the tank for oil leakage accumulation, control room, a tank of 5 m3, and commissioned automation units, fire suppression system and a network of lines and process pipelines.

Pump Station No 18

According to the order we received from LLC PMT ESPO in 2010-2012 VELESSTROY constructed Pump Station 18. It is located in proximity to Aldan town, Sakha (Yakutia) republic. The Company finalized a work package for construction of buildings and structures including building of main pump station, warehouses, utilities, power networks, process piping, gasoline station dispenser, fuel tanks, communication networks, alarm networks, automation networks, five floodlight towers, building of the control room, gasoline service station along with process piping.

Pump Station No 19

Pump Station No 19 site is located merely 15km away from a railway station therefore VELESSTROY did not face problems related to logistics – any construction material was supplied seamlessly, as required. Apart from the standard set of buildings and structures VELESSTROY built on this site, we are specifically proud of construction of substations with power capacity two hundred and twenty kilowatts. By the way, hundreds of kilometres of off-site power supply lines these substations are connected to were built by VELESSTROY, too.

Linear Operations station, Central Repair Station "Neryungri"

"Eastern Siberia - Pacific Ocean" (ESPO) oil pipeline includes not only the linear part, but associated infrastructure, including a 4 central repair stations. VELESSTROY has actively participated in construction of one of them in Neryungri. Employees of the company have erected construction and service complex with canteen, a communication center and a checkpoint, warehouse, garage, sheltered parking, and mounted the power line at 6 kV, equipped inside networks and lightning, connected diesel power station.

Central Service Station “Olekminsk"

During the construction of the central service station "Olekminsk" VELESSTROY experts faced with difficult soils and complex transportation scheme. They had to use the technology of horizontal thermal stabilization of soils and conduct serious installation work to ensure reliability and consistent deliverables quality. Technologically, horizontal heat setting differs from the vertical so that the condenser consists of blocks which collect cold in winter and spread it over the horizontal pipes disposed between the piles over the entire area of the building. The pipes are actually to 5 m long and they are located at elevation -1,5 m. 

The company has built a variety of technological and household facilities: rotational residential building, drinking water supply pumping station, parking and storage area, fueling station, fuel and water storage tanks. Networks and lines were assembled; units of automation and diesel power station were connected.
