OLES JSC PROVIDES 10 TONS ELECTRIC WINCH FOR VIETSOVPETRO IN SERVICE OF REPLACEMENT EXPLOITATION ACTIVITIES.…
OLES JSC PROVIDES 200 TONS REEL ADAPTER SYSTEM FOR VIETSOVPETRO IN SERVICE OF REPLACEMENT EXPLOITATION ACTIVITIES.
Having undergone a process of assessing the competence and experience from similar contracts that have been carried out for 3 years is only part of the steps for a new contractor to become a supplier for Vietsovpetro Vietnam – Russia Joint Venture. It was just a preliminary round.
In the next step, you must demonstrate your quality management system, design, construction, and supply chain capabilities to your customers to ensure your input resources are strong enough to create a product that meet all the highest standards in the oil and gas industry. The price of the product is not a criterion for evaluation at this time. That is the fairness that people in the industry still call “When you are strong enough, you will be able to play on the pitch”. And you can win or not is another story.
Winning the tender package “Supplying hydraulic winch 200 tons (200T Reel Adapter system for cable laying offshore” of Offshore Lifting Equipment Services Joint Stock Company or another name OLES JSC in front of a series of well-known foreign special winch suppliers, has made many contractors so far accustomed to importing to supply Vietsovpetro to be surprised.
Going into the process of executing a contract from designing, manufacturing, inspecting to fully assembling, it is obvious why OLES JSC can win. Choosing partners supplying equipment such as electric motors, gear boxes from EU / G7 is a good choice of OLES JSC. Quality is always a priority in the industry but to win you need to be competitive on price. It is the processing of mechanical structures and finishing products in the country that has helped to increase the competitiveness of the product.
From the success of contracts, it is hoped that in the near future Vietnamese businesses including OLES JSC will be able to provide many devices and products for the Vietnamese industry, especially equipment for oil and gas industry.
