system codes for vessel maintenance

[tonylazyz]

Can anyone advise if there is an industry-wide standard for organizing maintenance on ships, sytem-by-system?
For example:
10.0 Main engines
10.1 Fuel system (main engines)
20.0 Diesel generators
20.1 Fuel system (diesel generators)
30.0 Hydraulic systems
40.0 Refrigeration and Air Con.

I am involved in the build of a large (48 m) luxury yacht and want to organize all maintenance items section-by-section in one comprehensive and standardised listing. Other ship engineers must have had this problem before and I am guessing it has been standarized but I don't know where.

Thanks

We (

http://www.technofysica.nl)

have been involved in a maintenance program for for the turbines and related equipment of steam-driven oil tankers. We have an ABS certification for that. We are currently developping such a program for diesel driven installations, and especially for large dredgers (including dredging installations and peripheral equipment). To my knowledge, there are no official standards, adn we have developed our own. A good starting point is to tackle all such items during sea-trials, and compare all values to either existing references and standards, or to experience levels of companies such as us. You can perform periodic checks and see how things develop in time.

Standard and standard..

I am really not sure what you are looking for but the AMOS-maintenance system is in some organizations considered as a standard although a commercial product.

The SFI group system was a norwiegan standard but seems only be available through a company named xantic. very useful from a design point of view.

Thanks for the mention. In fact there is an update on the situation. SpecTec is now independent from Xantic and both the AMOS Maintenance program and the SFI Codification system is available through us

There are several formats depending on whether it is government designed, AMOS, marinized, shoreside designed, etc...

In the early 1990’s I developed a system heirarchy for a fleet of tankers. It was based on the various systems aboard a large vessel and broken down into the different equipment in the system, then into the components for each equipment, then into the parts of each component. In retrospect, it could have been more efficient, but it worked for many years fleetwide.

In those days, the system was run on DOS so I was limited to eight characters for the designator. I used a three alpha code for quick identification of the system then two digits to further set the series within the system. The last three digits were for the specific equipment and components. Usually, an alpha character was used to identify an ancillary component or sub-assembly of the primary equipment. In the Compressed Air System example below, the primary equipment is the compressor (compr) with the other items related to it using an ending alpha digit. This comprised the “nameplate” for the component, under which multiple identical component units could be added (such as Port or Stbd, #1, #2, etc…) This worked well for sorting purposes and the list is flexible enough to be able to add new equipment as required.

COMPR, DIESEL START CAS10250
MTR, DIESEL START COMPR CAS1025A
CNTRLR, DIESEL AIR COMPR CAS1025B
RECVR, MAIN DIESEL AIR CAS1025C
VLV, RELIEF MN DIESEL RECVR CAS1025D.

It is important to standardize your terminology and abbreviations also, for sorting by component NAME (left column) vs system number (right column). In this way, you can lump all of your motors together (for example) for maintenance purposes. See example below:

MTR, FIRE/BILGE PUMP BIL0626A
MTR, FO BLENDING PUMP FOS3465B
MTR, FOAM PUMP SAF5820B
MTR, FORCED DRAFT FAN SGM6602A
MTR, FRESH WATER PUMP FWS3600A

Modern applications can be utilized and molded to whatever scheme you want to develop. My advice is to put some thought into how you will personally use the system for maintenance and ordering spares and keep it simple for all users.
Good luck!
