We provide advice and consulting services in the area of Operation and Maintenance for Power Generation. Our experience in this field includes the experience of our
Consultants in power generation operation & maintenance.
Power + Energy Associates apply their expertise in O+M to Due Diligence, Conventional Thermal
Power, Combined Cycle Technology, Cogeneration, CHP for Industry, Gas Turbines, Steam
Turbines, Steam Generators, Boiler Plant, Heat Recovery, Process Steam, and Steam
Distribution. This advisory work can be extended through the various phases of a project
from the initial concept; selection of Operator, determining Facility targets and to
setting in place the systems and procedures. Ongoing assignments involve audits and the
regular review of plant performance in accordance with the conditions stipulated in
project agreements.
As Operation and Maintenance
Advisors we assist with negotiations, establishing
Agreements, appointment of Operators, the implementation of state-of-art asset management
technology, O+M procedures, O+M documentation and performance audit/ review. We use our
experience and expertise to put in place technology to enhance Facility O+M management. A
Benchmarking Analysis has been carried out for two combined cycle cogeneration plants
employing advance technology Aero-Derivative
Gas Turbines. This work involved reviewing existing
operational and maintenance data alongside business, financial and maintenance drivers.
Benchmarks were established along with options for improving the financial performance of
the plant taking account of risks. A case was presented for minimising maintenance costs
and balancing the risk with different maintenance arrangements. The analysis included
lifetime cost, operational risk, effect on availability, speed of response and plant
manning levels needed maintain a minimum level of service. The option of a fired hour
contract was considered. Various maintenance concepts were developed and a competitive
total maintenance service compared to employing maintenance staff for day-to-day
maintenance and employing alternative service providers to carry out inspections and
provide expertise. Companies were identified to support the proposals and the risk
associated with spare parts considered.
We were engaged to investigate and resolve
Operational Failures and Operational
Reliability for boiler plant and steam turbine plant in India. The assignment
was for a Cogeneration plant with solid fuel fired CFB boiler and a condensing steam
turbine generator. Records were examined, inspections made and the root cause of the
problems identified. As a result modifications and repairs were agreed with manufacturers
and the work supervised at site, including witnessing onsite re-balance of steam
turbine-generator, attending the plant re-commissioning and re-start of the plant to full
load. Follow up site visits were made, output and reliability performance monitored over
an extended period. The result was significant improvements to the overall operation of
the plant.
We have assisted with Operational
Trials on major coal fired power plants in the Far
East. P+EA set out a programme for coal
burn trials, directed the trials, acted as
independent observer and monitored the operation of the plant. It was concluded that the
trials were a complete success, demonstrating good handling and combustion characteristics
of the test coal, good combustion with low SO2, NOx and dust emissions these being well
below those of the comparison coal. The coal burned well, there were no reported problems
with auxiliary systems. Operational differences were observed between units with
classifier settings, use of mills and burner tilt settings. The effectiveness of the
sulphur injection (SO3) system was monitored and the operational performance of
electrostatic precipitators observed.
P+EA were assigned as Independent
Technical Auditor following a serious
over-pressurisation incident on a large reciprocating
engine generator unit. An initial investigation was
made when damage to the engine and engine systems assessed including exhaust system and
catalyst. P+EA were introduced to the Independent Internal Panel of Enquiry (IPOI) and met
with major suppliers involved. Following this, investigations were made, reports reviewed
and all related documentation studied. A view was provided on the Root Cause of the
Incident and recommendations for prevention of a failure reoccurrence provided. Following
on from this the extended review covered the investigative process, findings, maintenance,
repair and modification work, re-commissioning, and future operation and maintenance
of the Plant. The recommendations included implementation of an additional engine
protection scheme, updating O+M instructions and follow up and verification of
recommendations after a period of time.
Our work in the O+M field is varied and may also include the following:
- Review of Project Documentation
- O+M Technical Advisory Services
- Reliability and Availability Analysis
- Independent Assessment of Facility Operation
- Due Diligence and Technical Audits
- Preparing Operator Terms of Reference
- Negotiation of O+M Contracts
- Assistance to Lenders and Banks
- Reporting to Sponsors/ Owners
- Making a Formal Presentation of Findings
- Implementation and Follow Up
