Replacing a Jaquet FT3000 ODS with a SpeedSys 200 ODS on a combined cycled gas turbine (CCGT) Vattenfall operates a combined-cycle gas turbine at an energy plant in the Netherlands.…
Voting, regarding overspeed protection systems, can be defined by the number of safety loops that should switch to the safe state when an overspeed situation is detected. The desirable voting…
The FT3000 overspeed protection system, formerly supplied by the Jaquet Technology Group (now: TE Connectivity), has been discontinued by the manufacturer. Its obsolescence affects many end-users as the Jaquet FT3000…
The API Standard 670 is an industry standard and describes the minimum requirements for a machine protection system (MPS). This includes, measuring radial shaft vibration, casing vibration, axial shaft position,…
Excessive vibrations on rotating equipment like pumps, gearboxes, turbines and compressors are a clear sign that the equipment is not functioning properly. Equipment that is showing excessive vibrations will most…
AVR is specialized in processing various types of residual waste and converting this waste into energy and raw materials for households and businesses. In their plant in the Botlek (Rotterdam)…
It is essential to verify the functioning of every individual component of an overspeed protection system. This can be done during its installation, commissioning / turnarounds or troubleshooting. As this…
Overspeed situations on rotating machinery should be prevented at all costs. Even the slightest overspeed situation could lead to mechanical stress that causes rotating machine parts to deform. More serious…
Overspeed protection systems have a critical function in the balance between the safety and availability of rotating machinery. These protection systems should be proof-tested periodically to verify the system logic…
SpeedSys 200 & 300 are SIL-rated overspeed protection systems for rotating machinery. The systems are highly adapted to growing market demands and challenge overly complex rack-based systems. This article describes…
The leading standard for rotating machinery (API 670) states that (critical) rotating machinery requires a state-of-the-art overspeed protection system. The availability of electrical overspeed protection systems has grown ever…
