Gas Turbines
Gas turbine engines vary in size from micro (20-350 kW) to large industrial units (590 MW) and remain the product of choice for many operators worldwide in the power and energy industry.
The operational flexibility, efficiency and reliability make them ideally suited for use both offshore and on land. Also, with the transition to green energy, gas turbines play an ever more crucial role in supporting power grids and as replacements for retiring coal-fired generation.
However, this sophisticated equipment can and does occasionally fail, potentially resulting in financial losses of tens or even hundreds of millions of pounds. Failures can range from simple mechanical issues with valves or ducts to more complex issues such as blade failure, bearing failure or an instability with airflow and combustion. In providing a supporting role to renewable generation, gas turbine operation is transitioning further towards rapid starts and relatively short periods of operation, which have a detrimental effect on the life of many components, and can impact reliability and maintenance intervals.
Failure to meet contractual requirements in terms of performance, emissions or maintenance schedule is also a common complaint from operators.
Despite the significant technical challenges that remain, gas turbines will also be increasingly used for burning renewable fuels such as hydrogen. As with all new technology, there will almost certainly be reliability challenges and failures along the way, but the gas turbine market will continue to grow into the foreseeable future and “keep the lights on” for many years to come.

HOW DOES HAWKINS INVESTIGATE GENERATOR FAILURES?
1
Consultation
On receipt of the enquiry, we like to speak with you before we conduct any work, to obtain the background information.
These discussions help us to understand your requirements, as well as determine how much information is already available, including for example, service records, first-hand witness accounts, photographs, and videos.
We are also happy to provide you with an estimate of the cost of conducting a forensic investigation.
2
Inspection
If required and with your agreement, we will arrange to examine the relevant equipment, either on-site or at a workshop, to establish the facts regarding the failure and the circumstances surrounding it.
This usually involves taking witness statements, examining physical evidence and studying engineering drawings, specifications and manuals.
Wherever possible, we will retain faulty parts for examination in our laboratory, where we use a range of equipment, tools, and tests. Where a dispute remains or where facts are not available, we will provide an informed and professional opinion.
3
Reporting
Once our examination is complete, we will discuss our findings with you and prepare a report containing a detailed account of our investigation, conclusions, and where appropriate, further work or advice.
We are independent, impartial and unbiased and we are instructed by both Claimant and Defendant solicitors and insurers. We are flexible in terms of reporting and we work within the relevant Civil Procedure Rules and are effectively agents of the Court in everything we do.

Power & Energy
Hawkins' power experts have experience of forensically investigating losses worldwide on a wide range of power generation equipment from traditional thermal and nuclear power plants through to wind, hydro and solar generation as well as emerging technologies such as battery and flywheel installations.
Electrical Engineering
With the prevalence of electrical and electronic devices in the modern world there is considerable scope for failures to occur. These can range from the failure of a single electronic component to failure of multi-megawatt power plants.
Hydro Power
Hydro power generation was the first green renewable energy and battery storage facility. Hawkins forensic investigators have completed numerous investigation into hydro power plant failures.
Geothermal
Geothermal power systems rely on the use of steam/hot water generated by the heat within the Earth’s crust and as such, the working media is significantly more aggressive than conventional steam systems. This results in more issues with corrosion and scale formation which affects the availability and utilisation of the power generation asset or heat exchanger unit.
