Offshore Technology/Hoses Process Equipment Goes Offshore: Helping Deepwater Oil Exploration

Editor: Dominik Stephan

Eaton has developed a hose that would help the exploration of oil hidden beneath the surface of the water. These hoses undergo various rigorous tests in order to efficiently work in challenging scenarios. Read on to know more about the products that the company provides to work in the high-pressure environments.

Though deepwater oil exploration is the need of an hour, it is a challenging task to perform. For example off the coast of Brazil where one of the largest oil reserves in the world is buried in

a ‘pre-salt’ geological layer beneath miles of water and rock. If the oil is successfully explored and brought to the surface, Brazil will meet its aggressive goal of tripling its oil production— from approximately 2 million barrels a day to 6 million barrels a day— before the end of the decade. However, to achieve this, advanced equipment and instruments such as hoses are required.

Prior to 2010, subsea tree manufacturers typically relied on hose sources outside Brazil to bundle hose and build Hydraulic Flying Leads (HFLs). However, in 2011, when the manufacturers were required to adhere to the Brazilian government’s new local content regulations, Eaton approached few subsea trees manufacturers.

Working Together with Partners from the Offshore Industry

“Eaton got in touch with the tree manufacturers at just the right time,” said Sales Manager, Eaton—South American Headquarters, Pedro Cortonesi. “Since they were looking for a local hose partner to help them meet Brazilian content requirements, we explained that although Synflex hose is made at Eaton’s hose manufacturing facility in Aurora, Ohio, it is shipped to the company’s Guaratinguetá

facility. There, we add local content by cutting individual hoses to precise lengths, attaching corrosion-resistant stainless steel end connectors, wrapping the hoses into bundles and flushing and testing the completed bundles.”

How to make Equipment Offshore–Ready

In order to install the hose in the Brazilian pre-salt conditions, Eaton’s first mission was to emphasize on the solid performance and reliability of the Synflex hose. “Reliability is absolutely monumental for the hose that is installed under as much as 8,200 ft of water. Making it difficult and expensive to repair, in addition to the fact that hose failure can literally shut down a drilling operation, reliability plays very important role. Because of the many challenges and large scale investment involved in deep sea drilling, hydraulic hose must last for a minimum of 20 years. We explained how the company’s Synflex hose is made to endure long-term subsea duty in ultra-deep water, thereby helping to ensure uptime and keep project timelines on track,” stressed Cortonesi.

“Still, we had a lot of work to do in order to obtain the hose business. The customers wanted to be assured that Eaton knows the demands—that each hose must be engineered to order, undergo rigorous testing and be delivered within a four- to six-week time frame with no excuses,” he Source: Eaton India further explained.
