To reinforce the company’s strength in providing customized hose solutions, Eaton engineers met with the wet tree manufacturers to present their approach to each project. This included close interaction with the customer and in-depth analysis of tree configurations and hose requirements.

Knowing that proof-testing is mission critical in the supply of subsea hose—so critical that it must be witnessed by a customer-appointed inspector—engineers invited customer personnel to tour Eaton’s in-house testing operations in Guaratinguetá, where the application worthiness of each completed Synflex HCR hose assembly is verified.

Under the Surface: What Christmas Tree Have to Do with Offshore–Oil

The company manufactures Synflex high crush resistant (HCR) high-pressure hose, which was developed in response to increasing demand for oil drilling rig equipment that is almost fail-proof at extreme subsea depths. The company’s hydraulics facility in Guaratinguetá, Brazil, supports local exploration and development of pre-salt wells by providing HCR thermoplastic collapse-proof hose for subsea trees produced by leading oil and gas equipment manufacturers.

The subsea trees, often called Christmas trees because of their rudimentary resemblance to decorated holiday trees, control the flow of oil out of a well. Synflex HCR hose, which is part of HFLs that connect manifold blocks to subsea trees, takes hose construction and functionality to a whole new level. Each HFL is actually a bundle of individual HCR hoses that vary in quantity according to project requirements.

Extreme Environments Demand Extreme Measures

The hose’s flexible 316 stainless steel inner-locking carcass withstands over 5,000 psi differential pressure and up to 7,500 psi working pressure—extreme forces that are commonplace in ultra-deep water exploration. HCR hose is supplied in extremely long continuous lengths to the customers’ requirements, which can be over 10,000 ft.
