VIT conversion of auxiliary engines
Tier I auxiliary engines converted to variable injection timing, and certified.
The starting point
From fleet screening to a certified VIT retrofit: we identify the right engines, test onboard and certify the result.
We guided the owner from the first idea to the last signed document. Before the VIT was installed on their Tier I four-stroke auxiliary engines, we identified the engine group with the most member engines. We prepared all the regulatory documents, planned and carried out the test onboard, adjusted the engine to its best possible setting within the regulations, and completed the documentation for both parent and member engines.
How we did it
- 1Fleet screening
We reviewed every Technical File and EIAPP certificate and found the engine group with the most member engines.
- 2Documents and exemption
We prepared the documents for the measurement campaign, accepted by class, and applied to the flag state for an exemption, so the ship stayed legal.
- 3Test onboard
We prepared the ship, planned and carried out the test, and our technicians adjusted the engine to its best possible setting, based on the measured results.
- 4Documented
Witness report from the chief engineer, with full documentation of the test.
- 5Certified
The amendment to the Technical File completed for parent and member engines.
What the customer got
The best candidates
We find the engine group with the most engines, so one approval gives you the greatest potential.
One team, start to finish
We prepare the ship and apply to the flag state for the exemption, so the ship stays legal from start to finish.
Tuned, not just installed
Our technicians set the engine to its best possible setting, based on measured results.
Certified and documented
An amendment for parent and member engines, with full documentation of the test.
With you all the way, until the last document is signed.
Read the technical details
- Evaluated the owner’s idea, and reviewed every Technical File and EIAPP certificate to find the engine group with the most member engines under the same parent engine
- Prepared the pre-supportive documents and the test plan, accepted by class
- Applied to the flag state for an exemption for the modification, so the ship stayed legal throughout
- Prepared the ship for the test
- Measured performance and emissions on the parent engine onboard, with the simplified measurement method of NTC 2008
- Adjusted the engine to its best possible setting, based on the measured results and within the regulations and the engine’s accepted limits, before the amendment test
- Documented the test in full, with a witness report from the chief engineer
- Developed the parameter check method for the member engines, without emission measurements
- Completed the amendment to the Technical File for parent and member engines, and followed it through approval with class
