When Sigma's position in the wind power construction sector has been firmly affirmed through the Ben Tre V1.3 Offshore Wind Farm, Sigma’s employees have continued to take on their duties and set out on the road towards Soc Trang. On October 28, 2020, the bus transporting engineers and all necessary equipment stopped the wheel at Noi Bai airport to take a flight to Can Tho city, then moved to Soc Trang, leaving behind a solid back, the hundred-sided struggles to rely on "loved ones".

Sigma's main force at Soc Trang 7 Offshore Wind Farm
Officially commenced during the heavy monsoon season in the western coastal region (October to March of each year), the M&E construction at the Soc Trang 7 Offshore Wind Farm faces great challenges. This is the time when professional marine construction contractors avoid going to the sea because of high winds of level 6 and 7 with the intensity of over 10.8 m/s and the large underground waves with continuous intensity during this season. However, due to the commitment on progress when receiving the project, Sigma still mobilizes many modern machines and the burning enthusiasm of Sigma's employees to go to the sea. With the spirit of taking advantage of every second, every minute, excluding day and night, regardless of the favorable conditions, Sigma soldiers on Soc Trang site were ready to start working.

Soc Trang 7 is a large-scale wind farm project in Soc Trang province, with a total design capacity of 120MW, built with 2 phases, on the total surveyed area of ​​3,100 ha. In the year 2020/21, the Employer intends to construct an offshore wind farm consisting of 7 wind energy generators type Vestas V150 with a hub elevation at 96.5 meters above the foundation, with a rotor diameter of 150 meters and a nominal capacity of 4.0/4.2 MW each and all necessary electrical infrastructure to connect the wind farm to the local grid. The nearshore wind farm is to be located in the waters off the Vietnam coast.

With the supply and installation of wind power systems to become the BOP contractor of the project, Sigma is committed to mobilizing large-sized equipment and working at all turbine locations simultaneously. We always put safety, quality and progress on top to complete the first phase of the project together with Soc Trang Energy Joint Stock Company. Sigma's construction works include:

  • Construction of a bridge to connect sea-to-shore turbines with a total length of 7.4 km
  • Construction of 22 kV transmission line including cable trench route and overhead transmission line from the bridgehead to the plant's transmission station.
  • Construction of the Scada optical fiber communication system from the turbine to the operator (located in the 110 kV transmission station of the plant)
  • Installation of 07 wind turbines near shore
