GE Oil & Gas
Subsea Wellhead SolutionsAdvanced technologies with industry-proven reliability, performance, and safety for all operating conditions
Reliabilityis a must
GE pushes the technology boundaries needed to increase reliability, flexibility, speed and performance. With more than 40 years of in-field experience and over 1,000 systems installed worldwide, our heritage includes robust casing connectors dating back to the 1960s and game changing wellhead designs back to the early 1990s. The driving force behind our successful technology has always been a design approach that draws from our customers’ actual in-field experience, and their evolving need for higher efficiency and dependability. Through collaboration and commitment, our people have delivered such innovations as the patented MS metal-to-metal sealing technology, robust wellheads and connectors now used around the world.
Today, we continue to partner with operators, technology and services providers to enable safe, sustainable, and reliable growth in the offshore industry. Our products are designed, tested and proven for industry-leading performance, safety and efficiency in a wide range of operating conditions.
We tap into the full breadth of experience across all GE’s different industrial sectors — from healthcare to aviation, power and water — and apply it to oil and gas. We call this synergetic approach the GE Store. It unlocks the power of over 50,000 technology experts around the globe who are continually inventing the new industrial age — helping us bring innovative solutions to the market faster and more cost effectively.
To help projects overcome increasing capital costs, we develop standardized configurable solutions that improve speed to market and enhance operations. Our innovative FastWorks approach to product development combines tools and behaviors that deliver better outcomes for customers, faster. FastWorks is reshaping our business culture and the way we collaborate with customers, bringing all project teams together under a unified goal. It’s already helped deliver more than 75 MS-700 subsea wellhead systems with industry-leading delivery schedules well ahead of customer due dates.
collaborating for speed
Offshore operations are moving into deeper waters, more remote locations, and more challenging environments with increasing temperatures and pressures. As they push past the boundaries of 10,000 ft (3,000 m) depths and 30,000 ft (9,100 m) wells, financial pressure and technological complexity increase exponentially. In these scenarios, collaboration among oil and gas players is fundamental to provide the industry with production systems and expertise to enable optimized, ultra-reliable performance throughout life-of-field.

Advanced connector profiles The H-4 connector family is a GE patented design that has been adopted industry wide for its leading reliability dating back to 1964. Smartly engineered with simple operating characteristics and advanced metal-to-metal sealing, the modern hydraulically operated H-4 provides excellent bending and tensile load capabilities, and a long, economical service life. It’s also highly versatile and field-proven for BOP stack to wellhead, LMRP to BOP stack, and completion tree to wellhead connections.
