The Technical File

What is it?

Basic Structure

How to make entries

Parts procurement traceability

Your responsibilities as the owner

What a surveyor will expect to see

Charge air cooler maintenance


3/23

What is it?

Technical File is a record containing all details ofoperating parameters, including components andsettings of an engine that may influence its NOxemissions and continued compliance

Most engines installed after January 1st 2000 haveTechnical Files that must be kept up to date

societies (USCG, TC, ABS, LR) to verify compliance

Affects IAPP certification

The shipowner is responsible for maintaining theTechnical File and having it available for surveyor auditon demand

Verifying NOx Compliance on board

3 ways to verify, simplest is

Engine Parameter Check method to verify that anengines component, setting and operating values havenot deviated from the specifications in the engines

Technical File:

1. Check engine parameter

2. Identif NOx related com onents

3. Record changes to NOx components

4. Identify adjustable features

Must have EIAPP certificate and maintained emissionscompliance since last survey in order to use Engine ParameterCheck Method


19/23

Engine Parameter Check Method MaK M43C

Check the following:

1) Adjustments of the valve train

Spacer plates under cam follower brackets (non FCT) Angle of mini-eccentric bushings (FCT)

2) Identification numbers match MaK listing

3) Piston-cylinder liner height

4) Functioning of FCT if installed

5) Flywheel marking aligned with dead center indicator

1) Adjustments of the valve train

Spacer plates under cam follower brackets (without FCT)

Angle of mini-eccentric bushings (FCT)


5) Flywheel marking aligned with dead center indictor

Parts procurement traceability

Owners procurement databases (purchaseorders, invoices)

Ships documentation (packing slips, invoices,etc)

Online www.MyToromont.com (for electronic

If non-OEM parts without Cat or MaK NOxmarkings are used for scheduled maintenanceand repairs the owner is responsible for proving

emissions compliance to the surveyor this isusually very costly!


23/23

Recommendations

Retain detailed records of all maintenance and repair work and partspurchases for each engine

Follow the published engine maintenance recommendations. Workwith your Cat or MaK dealer on any considered changes to avoid

under/over - repair

Avoid non-OEM parts and repair facilities

Do not change any engine operational settings or modify any

Keep the on-board Technical File current and retain a shore-side copy

Maintain the engine charge-air cooler in accordance with the followingarticle

Remember that your authorized Cat and MaK dealers are the safestsource of information and assistance on engine emissions - relatedissues
