 During recent years, Alba Power has worked closely with a number of major gas turbine clients, users and operators on tailoring support options available to suit all operations from stand-by through to main power and compression requirements.
The case studies in this section of the Alba Power website have been selected to illustrate the qualities of innovation (both technical and commercial) and customer responsiveness which characterise Alba Power's international gas turbine service operations.
On-site change-out
Unit supply
Unit overhaul
Spares supply
Controls issues
Off-engine fuel skid
Case 1 ? On-site gas turbine change-out
The problem:
The client, a leading independent UK power provider, had identified high vibrations and power loss during normal operation at a power station. Overhaul operations were required, but all works had to be carried out on site to maximise the efficiency of the workscope and minimise the any delay in operations.
The solution:
Alba Power initially despatched a highly experienced technical support team to the site to inspect the unit and offer a number of alternative technical and commercial overhaul options.
Once the most cost-effective option had been identified, Alba Power organised and supplied all personnel, tooling and spares required to overhaul the unit on site within the required timescales.
Utilising a shift system and parts exchange programme, Alba Power achieved the feat of reinstating the unit within one week from initial notification through to successful re-commissioning, while operating within the commercial restraints associated with modern power generation requirements.
Case 2 - Unit supply/de-commission/re-commission
The problem:
During high nominations, the client, an independent oil and gas operator, was suffering unit loss on a North Sea installation. To maintain output of the field, however, the client required a unit delivered whilst the failed unit was removed and the replacement unit re-instated.
The solution:
Alba Power supplied a fully-overhauled gas turbine unit to the client within 48 hours of initial notification. Utilising a three-shift schedule, the failed turbine unit was removed and the berth made ready for the replacement unit. Within four days of contract agreement, the client was able to continue normal operations. Despite the intensity of the programme, all work was completed by Alba Power in advance of the predicted timescale and under the required budget.
Case 3 - Unit overhaul
The problem:
The client, a major North Sea operator, had identified loss of power after initial service life use, from which specific modifications, overhaul and spares supplies were required.
The solution:
Utilising Alba Power?s in-house gas turbine overhaul facility, the unit was received and overhauled within the required timescale, and returned to the client having achieved a 27% saving over initial budget discussions.
Case 4 - Spares supply
The problem:
The client, a nuclear power station in Canada, had its unit shut down due to a relatively minor bleed valve issue.
The solution:
Alba Power?s engineering personnel hand-carried replacement parts and installed the unit on site, allowing an early re-start of the process.
Case 5 - Controls issues
The problem:
The client, a leading UK power provider, had experienced Netcon unit closeout leading to unit issues.
The solution:
Alba Power?s engineering personnel travelled overnight to site to allow early re-work of the system. At the same time, maintenance was carried out to ensure prolonged running before the next maintenance requirement.
Case 6 ? Off-engine fuel skid
The problem:
The client, a major North Sea operator, had spurious fuel system issues which were causing engine failure and problematic operation.
The solution:
After investigation by a team from Alba Power?s field engineering personnel, the system was stripped and overhauled prior to re-commissioning. All works were carefully scheduled for early completion to ensure that operations were not interrupted.
