The provision of system upgrades and retrofits is an important aspect to the operation of a gas turbine package or plant and is the platform to improve operational reliability and remove unscheduled downtime.
Our solutions can be tailored to the individual needs of the customer whether it is a black start solution encompassing sequencer, governor, AVR, excitation, generator protection and fuel system replacements to a relatively simple plug and play governor replacement.
Furthermore, we can also provide remote control and remote monitoring solutions through a secure gateway. This allows a condition monitoring and assessment service to be provided at low cost with rapid access to technical support often situated 1000's of KM's away.
The control systems on mature turbines can often be passed the stage where they can be reliably supported. Many components are obsolete, and have been for many years. The failure of one key component may lead to an extended shutdown while replacement are located and/or engineered.
Where parts are re-engineered, it can lead to ancillary issues, such as complying with Management of Change processes at many sites.
In addition, the availability of clients needs to be considered, as there is a declining pool of resources who are trained and understand the older systems.
In order to remove these risks we are able to offer Controls Upgrades based on modern PLC based platforms, that as well as remove obsolescence issues, offer the following benefits:
There have been significant advances in fuel throttling technologies, both in valve, actuation and Control.
We offer an integrated gas fuel valve upgrade to suit installed GEC packages. The system is made up of three primary components, the valve, actuator and electronic control unit.
We are also able to supply upgrades to the original Phase 1 and 1.5 Lubricating Oil Console supplied with GEC packaged Avon Turbines.
Originally, GEC Packaged Gas Turbines contained many instrumentation switches, which was a common standard at the time.
We offer to change many of these switches in favour of modern transmitters. Normally this is carried out at the same time as Control System Upgrades. Upgrading the turbine package instrumentation has the following advantages:
We are actively involved in the relocation and refurbishment of existing gas turbine packages.
At Greenray Turbine Solutions, we strive to continually develop our capabilities in order to provide an unrivalled service.
Our field engineer's travel globally to carry out our services.
Although we're adept at solving problems, we prefer to prevent them through regular servicing, which highlights issues before they become a problem.
Our people are experts and they're all our own. We're extremely proud of our field engineer's pedigree, with expertise ranging from working in difficult offshore environments through to land power generation.
Legacy machines are in our blood and everything we do is designed to work in the best possible way with them.
