... Abstract The offshore industry needs energy-efficient and cost-effective solutions to scale up the energy transition. Through the development of a series of lean, all-electric Subsea Valve Actuators (OTC-32346-MS), most processing valves can now be easily electrified. However, some critical...

... of protection and a SIL rated HIPS. HESD comprises of electronic transmitter on each flow arm (initiator), Safety PLC (logic solver) for offshore multi-well platform and SSV (Master valve) and export ZV as final elements and the HIPS system is considered as the second layer of protection. However, the risk...

... production and processing sites. Linear valves and actuators play a critical role in subsea systems as they allow for lightweight and compact design of infrastructure. The first electric subsea actuators for linear valves were expensive, large, and non-retrievable due to complex safety mechanisms using...

Real-time and recorded mode data was also used to improve the subsequent lower completion installation as well. The ability to acquire and transmit data in well construction operations that were conducted blind...

... was ramped up to around 17%. As a results, the well was shut in and methanol was injected from the wellhead, upstream of the production choke, which confirmed no response at downhole sensors. The main suspects were Surface Controlled Subsurface Safety Valve (SCSSV) and hydrate blockage(s). Fig.1...

However, the production system was experiencing high temperature and high gas and condensate production rates combined with low water production rate. This resulted in very low scale inhibitor injection...

... of controlling valves on a subsea Xmas tree. All-Electric technology will enable simpler field development with less topside equipment, simpler umbilical, increase component standardization that is less sensitive to water depth, and with enhanced capabilities in condition monitoring. The main strategic objective...
