TNEI is an independent specialist energy consultancy providing
technical, strategic, environmental and consenting advice to
organisations operating within the conventional and renewable
energy sectors.
Oil and gas services
TNEI offers services to the oil and gas industry in three main
areas: • Acoustic and noise • Consenting, permitting and
environmental management • Electrical system analysis and
consultancy.
Whatever your requirements, get in touch with our experts to find
out how we can support your oil and gas project.
Acoustic and noise services
We offer a complete suite of noise consultancy services, including
environmental and occupational noise assessment, vibration and
blast monitoring and noise control and management.
Our large noise team, all of whom are affiliated with the Institute
of Acoustics, has experience across a wide range of sectors,
including the oil and gas industry. Our diverse mix of knowledge
and experience means that we can match specifically skilled
consultants to your project, ensuring you receive the best possible
advice.
The projects we work on are often subject to high levels of
scrutiny by planning authorities, enforcement agencies and third
parties. TNEI provides robust technical services to ensure that the
assessments are defensible throughout planning and application
processes, at Public Inquiries or through other legal proceedings.
Our Expert Witnesses regularly work on planning appeals and attend
Public Inquiries and we have an excellent record of success in this
area. Our team has prepared evidence for over 30 Public Inquiries,
for which all noise issues have been resolved to the satisfaction
to the appointed Inspector / Reporter.
The TNEI team utilises the latest noise modelling software
alongside our own bespoke software models to produce accurate,
quality controlled assessments. Hardware includes a large stock of
environmental noise monitoring kits, meteorological measurement
equipment and occupational noise monitoring equipment, which means
we can respond quickly to our clients’ monitoring requirements and
run multiple projects concurrently and efficiently.
Our acoustic and noise experts, together with our modelling
software and hardware mean we are expertly placed to support the
noise requirements of your oil and gas projects.
Specialist services that we offer to our oil and gas clients
include: • Noise propagation modelling • Compliance monitoring •
Noise control and noise management • Silencer, enclosure and
barrier specification • Investigation of noise complaints •
Occupational noise assessment.
Consenting and permitting
Our consenting and permitting services cover shale gas, methane,
oil and liquid natural gas (LNG) projects.
Areas for exploration and extraction must be carefully considered,
mitigation needs to be meaningful and public consultation has to be
timely and genuine if proposals are to be favourably received by
local communities, protection agencies and mineral planning
authorities. TNEI has the knowledge and experience to actively
manage onshore oil and gas proposals through the planning,
pollution prevention and control systems of England, Scotland and
Wales.
Our comprehensive range of consenting and permitting services
includes: • Initial site investigations and landowner
identifications, undertaking
geological and hydro-geological assessments to aid a selection of
target areas for exploration. We also engage with landowners to
secure future access for investigation and operation.
• Site appraisals to establish the design parameters against which
the environmental, social and economic effects can be assessed.
This allows the incorporation of appropriate and effective
mitigation measures to make proposals acceptable to decision
makers.
• Community consultations to build and manage relationships and
establish trust. TNEI’s approach is meaningful, timely and
consistent with local and national government expectations. We can
design and deliver bespoke community consultation programmes
• Environmental Impact Assessments, risk assessments and awareness
statements, conducted by in-house environmental, acoustics, GIS and
civil engineering experts. TNEI is accredited under the Institute
of Environmental Management and Assessment’s Quality Mark
scheme.
• Management of consenting and environmental permitting and
applications through the UK’s planning and pollution prevention and
control systems.
Electrical system analysis and consultancy
Our electrical system analysis and consultancy services draw upon
our excellent knowledge in consenting and permitting, environmental
assessment, civil and structural design, geotechnical surveys,
cable routing and installation and operations and
maintenance.
Our services include: • Power system modelling and analysis using
the majority of software
packages, including ETAP • Electrical protection setting and
coordination studies • Arc flash risk analysis • Harmonic
distortion prediction, measurement and filter design • Generator
AVR and governor modelling and system transient
analysis • Equipment failure independent root cause assessment •
Earth measurements and earthing system design.
All work is performed to DEP, IEC or other appropriate standards as
required. The combination of our network modelling software, IPSA,
and our experience provides TNEI with a unique capability to
provide clients with bespoke analysis solutions.
Whatever your requirements, get in touch with our experts to find
out how we can support your oil and gas project.
Case studies
Service: Transformer overload assessment Client: Petroleum
exploration and production company
An offshore oil platform had reached the end of its design life;
however recent drilling resulted in a requirement for the platform
to remain operational. The platform contained four inductive
reactors, each in series with a step-down transformer. The original
design intent of the reactors wasn’t known by the company
responsible for operation and maintenance of the platform. The
reactors were at the end of their serviceable life and required
removal or replacement. TNEI was asked to determine the reason for
their presence and comment on the potential for removal as opposed
to replacement.
The assessment considered the following possible consequences of
removal: • Fault levels in excess of downstream equipment ratings •
Increased motor starting current flows with resulting short
term
impacts • Increased transformer inrush currents with resulting
short term impacts • Upstream harmonic voltage distortion increases
with resulting long
and/or short term impacts • Upstream high frequency voltage
distortion increase with resulting
long and/or short term impacts.
Each risk was considered both pragmatically and through
calculation. All possible consequences were concluded to be
negligible with the exception of increased upstream voltage notch
amplitude. Voltage notching had been captured by TNEI during
measurements and was characteristic of 6-pulse rectifier circuits
found on converters supplying DC systems.
Excessive voltage notching increases the likelihood of: •
Mal-operation of voltage measuring circuits such as generator
Automatic Voltage Regulators (AVRs). • Mal-operation of power
electronic equipment with automatic
switching/commutation controlled with reference to voltage zero
crossing points.
• Mal-operation of frequency measuring devices such as frequency
based protection relays.
• Mal-operation of point-on-wave control devices such as generator
synchronising controls.
TNEI concluded that reactor removal should be performed cautiously
and recommended a staged approach involving the identification of
the primary sources of notching and upgrade of the primary sources
identified.
Service: Provision of environmental management plans Client:
Petrofac
Following a change to the design philosophy for the refurbishment
and upgrade of a North Sea oil and gas platform, TNEI provided
supported to Petrofac’s health, safety and environment team. This
involved reviewing and updating a range of environmental reporting
and environmental management plans, as well as undertaking a
desktop review of the introduction of a methanol recovery process.
The review required consideration of best available techniques
relevant to the processes involved.
