The company was established as a Field Service company with emphasis and core strengths within the Control systems and DLE Mapping. Due to our close relationships to the North Sea (highest density of DLE units), our experience and capabilities within the DLE technology, particularly the Dual Fuel DLE, are probably amongst the strongest in the world. Through the past years, we have grown our Field service capabilities to cover the entire package, or as we say, “from flange to power”. Our field service capabilities includes LM level 4 mechanics as well as full-service capabilities for the driven equipment (Generator/ Compressor).
Dry Low Emissions – DLE Combustion Mapping
DLE Combustion technology is based on a premixed combustion, where fuel and air is mixed prior to combustion, in difference to a diffusion combustion, where fuel and air are mixed during the combustion. The premixed combustion has ~1/10th of the fuel-air ratio range in comparison to diffusion combustion.
To achieve high availability/reliability and long-term operability, it is critical that the turbine is mapped and optimized for the site-specific conditions.
The DLE technology utilize CDP bleed valve(s) to control the fuel-air ratio, which, when open, is a direct loss of efficiency. Optimizing the DLE combustion schedules to site-specific load operation points, can in most cases significantly increase the turbine efficiency, and decrease fuel and CO2 emissions.
Practical cases show that an optimized DLE efficiency map, can increase the overall efficiency upwards of 5%, which for a LM2500 DLE equals ~2 million Sm3 of natural gas and ~5’000 tones of CO2 annually.

The Norwegian government made the DLE technology mandatory for all new installations when it was launched in 1995, which has resulted in the highest density of DLE units, as well as a large fleet of the DLE dual fuel technology.
Due to our close relationships to the North Sea, and our extensive field background, our experience and capabilities are probably amongst the strongest in the world.
We provide DLE mapping for the full range of LM turbines, and are specialist on the DLE 1.0, DLE 1.5 and DLE 2.0 theology including the DLE dual fuel technology.
We provide optimized DLE mapping for single or paralleled unit(s), targeting load optimization, optimal fuel efficiency and long-term operational reliability.
We also have our own emissions equipment for on-site DLE Mapping, avoiding the use for 3rd party vendors offering vast savings. The analyzers are small and light weight with ultra-rugged construction, suitable for travelling, helicopter mobilizations and field applications.

Semi / Annual Service and Inspections
We believe the key to long-term availability and reliability, as well as turbine efficiency, is adequate and high-quality service and inspections to determine and correct underlying deteriorations.
Our observations from years in the field is that the turbine receives most of the attention, while the equally important balance of plant and support system does not necessarily receive the equal amount of attention.

We supply pre-organized work orders or packages, to be conducted in conjunction with the offshore maintenance crew and/or depot service provider. We could support you organizing of the planned maintenance orders, provide updated calibration certificates and/or adjusted work packages post assignment.
We believe that with an increased focus on some of the advanced functions or systems, and a tailored package maintenance, it is possible to reduce the periodic service outage program as well as increasing the availability and/or reliability.

Periodic Healthcare Packages
Our typical service assignment has been reacting to a failure or urgent requirement, usually after a forced outage or failure.
Looking at past assignments, we see a common trend where many of the forced outages are related to minor issues that could have been avoided with an increased focus on turbine related instrumentation, as well as functions that require a sequence to verify.
Our belief is that by verifying the health of the equipment, not only go/no-go, long-term situations availability and reliability will increase.

Our healthcare package is made specifically for actual site, and typically looks at and verifies the functions of the systems to ensure the response time and function for each component/system is “as expected”. All this to ensure premature component failure.
Examples:
- Verifying Valve Response time to discover valves degradation.
- Verify dual fuel system for back-flow issues.
- DLE mapping schedule verification to detect operational boundaries or “out-of-schedule” operation prior to disturbance/failure.
- Verify operation parameters to detect hidden issues e.g.:
- Ignition time
- Ramp shape/time
- Accel/Decelramps
- Max load/power

Resident Engineers
A gas turbine powerplant is complex, and usually a production-critical part of the operator’s business.
Ensuring that the installation and commissioning are conducted at the highest standard, and/or overseeing operation and maintenance, can be critical to the initial startup and operation of the gas turbine plant.
Our Resident engineers have a minimum of 10 years specific turbine hands-on experience. They can either act as your representative ensuring the EPC/OEM installs and commission the plant at the highest standard, or act as an in-house specialist to support and train your team in operation and maintenance.
