Offshore is without question one of the most challenging working environments for the oil and gas sector. The harsh weather conditions and remote location add a unique layer to everyday operations. Having impeccable timing takes on a whole new meaning in maintenance tasks. I’m touching the ground on this subject because AS-Schneider recently had me assist a client with their valve technology. The project was for the gas lift compression module of a floating production, storage, and offloading (FPSO) vessel in West Africa. We not only completed the job but also got to learn genuinely valuable lessons worth sharing. Thus, I’m happy to have the chance to do so today through this blog. Here’s the story of how we helped a dear customer, an upstream contractor, obtain double block and bleed (DBB) valves that met the site’s tight constraints on space, weight, and vibration.

At last, we reached the final delivery of our hydrogen embrittlement series. In part IV, we continue our interview with Material Testing Institute’s expert, Brain Kagay. Before, in part III, he shared precise insight into the effect of hydrogen embrittlement in different materials (metallic and non-metallic). Now, he’s disclosing more vital information relevant to the future blended operations of natural gas-hydrogen to be held in Germany’s existing grid and what’s next for research of hydrogen effects on materials.Continue reading
Here is the third part of our hydrogen embrittlement series with special guest Materials Testing Institute’s expert Brian Kagay. In part II, we addressed the causes of hydrogen embrittlement in valves. So, naturally, in this installment, our conversation flowed toward the effects of embrittlement by H2 in different types of valve materials.Continue reading
Welcome to the second delivery of our hydrogen embrittlement series. In this follow-up piece, our talk with Materials Testing Institute’s expert Brian Kagay turns to a new topic that complements part I’s basics of H2 embrittlement and its effects on valves. Here, the focus is on the causes behind valve embrittlement by H2. We also go over the enabling factors, how they impact the welding process, and the ways to spot affected materials.Continue reading
Germany is hard at work on becoming a decarbonized region. The country found a scalable solution in hydrogen that favors all parts—the environment, citizens, and industries. To get the H2 initiative started, the government, with the help of the scientific community, is developing several macro projects. The first phase focuses on blended operations that lead to the controlled addition of hydrogen into the existing natural gas grid infrastructure.
Under such a novel context, it is natural to inquire about the potential implications of gas blending. How can the addition of hydrogen affect the existing systems? Is hydrogen embrittlement of materials a possibility? What are the causes? How to prevent it? These are rather important questions raised by plant operators. So, as valve manufacturers, AS-Schneider felt committed to taking action and finding answers. We sent our team to a one-on-one meeting with specialist Dr. Brian Kagay. His work in the prestigious Materials Testing Institute at the University of Stuttgart qualifies him as an expert in this subject. If you are a plant operator, you don’t want to miss out on what he had to say.Continue reading
The cease of natural gas imports from Russia forced Germany to switch from energy providers. Since then, Norway has grabbed the number one spot as the main supplier. To secure reliable gas transfer and distribution, all facilities within the circuit must be at peak capacity. One of those facilities is a Gassco plant located in northern Germany. The revamped Emden natural gas terminal kicked off operations in 2016 with the operative premise of providing an availability delivery rate above 99%. Since the start-up the plant did not reach its potential due to a leakage problem at the shut-off valves. Together with the customer, we set about working out a solution to achieve the high requirement of 99% availability. Here’s how we helped Gassco get to the promised target.Continue reading
One of the things that I enjoy the most about my job is discussing new improvement opportunities with clients. Situations like that push me to engineer viable solutions that solve operational setbacks, so they can enjoy more reliability and safety at work. And that was what happened when I designed the practical test installation procedure I’m about to share. It was for a double block and bleed (DBB) ball valve installed in a gas storage facility.Continue reading
Every engineer encounters the challenge of having to choose one technology over another. A notable example is specifying the valve solution for a given process line. Sometimes the choice is evident. Other times, it is a tight horse race of options. In light of that, in this article, I want to focus on a topic I frequently get asked about: the differences between floating and trunnion-mounted ball valves. Selecting the most valve of the two for a specific service could be tricky at times. Thus, knowing what sets them apart helps a long way. Read on to learn about both valve solutions. My goal is to lead you to identify which design is more appropriate.Continue reading
Valve manifolds are flow management devices of ever-growing interest for operators, maintainers, and design teams worldwide. Even under today’s landscape of ongoing innovations, they continue to be a go-to technical solution for fluid control in systems. When two or more valves are involved, that is.
Since their deployment extends across diverse processes in several industries, it is only fitting to seize the opportunity to offer knowledge on them.
What are valve manifolds? When to use them? What configurations are available?
These are some of the questions to address in this introduction feature. Please, continue reading below to get the details.Continue reading
This article presents an overview of valves, their functions and the commonly used types of valves in the industry. The design principle, application areas, benefits and disadvantages of various types of valves are presented. Different methods of valve classification are also discussed to highlight the key considerations in valve selection.Continue reading
