1 Ship Machinery and Equipment Maintenance Lloyds maritime Academy 28/29 Jan 2010 Dr M Raouf Kattan Managing Director Safinah Ltd Hull, Tank and ballast tank maintenance 1Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

2 Coatings Are they just paint? or Are they engineering systems? Lloyds maritime Academy 28/29 Feb 2010 Copyright Safinah Ltd

3 Sign post Impact of IMO Regulations –Ballast tank issues –Cargo tank issues –Outer hull issues In service monitoring Maintenance regimes Repair regimes Data collection Possible issues 3Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

4 Impact of IMO Regulations IMO PSPC for dedicated seawater ballast tanks –Has elevated the focus on coating performance Fuel prices –Has elevated the focus on outer hull condition IMO PSPC for Cargo tanks pending 4Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

5 IMO Regulations Treaty on Ballast water management systems IMO Guidelines for Maintenance and Repair (M&R) of ballast tank coatings (void spaces and PMA) 5Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

6 Ballast tanks The worst is yet to come –New build CTF requirements –Compatibility with BWMS –Distinction between Maintenance and Repair –IMO Guidelines for M&R of ballast tank coatings 6Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

7 Ballast tanks As built records required – CTF In service monitoring by IACS likely to take the following format: IMO PSPC –In service maintenance, repair and partial re-coating shall be recorded in the CTF in accordance with the GUIDELINES for coating maintenance and repair 7Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

8 Maintenance and Repair Clear Distinction –Maintenance – activity that maintains but does not improve condition –Repair – activity that improves conditions –Basis is IACS Rec 87. 8Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

9 Assessment How to assess condition –Who to do it –How to define areas under consideration –Ambiguities of area of breakdown How to record How to audit 9Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

10 Frequency Every 5 years all tanks Fair and Poor – annually Poor, Fair Good as defined in IMO A.744(18). –Plate: 20% –Edges: 50% 10Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

14 Maintenance Regimes Need good information –All vessels over 6 years of age inspect all tanks by crew annually (possibly earlier). –Provide a report of condition –Prepare a maintenance plan –Prepare a repair plan –Record findings and actions in CTF 14Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

15 Maintenance regime Prepare –Remove mud, oil, grease etc., Wash down, Dry, Mech prep. Climate Apply –Epoxy based, compatible to existing (cross testing?). DFT to specification!!! 15Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

16 Repair regimes At dry-docking or specialist location –Status of riding squads not yet fully clear, but current reading is that this would be maintenance. Use of specialised equipment Prepare a proper plan of action 16Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

17 Repair regime Preparation –Remove mud, oil, grease etc. FW wash, Dry, St2 or Sa2.5 for Fair, Sa2.5 for Poor. Feather coating, soluble salts, climate control. Application –According to IMO PSPC to required DFT (compatibility – cross testing!!) 17Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

18 Data Collection Newbuild CTF – Contents not yet fully agreed and expect variability (IMO/NACE/IACS proposals). Crew to keep records in a consistent format for maintenance and for auditing Keep repair records for auditing Computer based systems in the near future. 18Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

19 Possible issues BWMS compatibility is a big unknown at present, no one making any real claims. Ownership changes and hence coating supplier changes – compatibility issues Maintenance logs. Costs of through life maintenance and repair Qualification of surveyors/auditors 19Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

20 Possible solutions Data build up for coating life to allow proper planned maintenance to be developed. Electronic CTF e.g. Elcoship software New repair and maintenance strategies - outsourcing 20Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

21 Outer hull Direct relationship to fuel consumption Longer history of owner interest Computer based tools emerged onto market Raising need for regular maintenance to save fuel. 21Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

22 However Invasive species issues –Require new technology solutions –In water hull cleaning desirable but can result in invasive species issues. –If not acceptable then need more dry- docking 22Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

23 However Coating technology –30 years of TBT stability gone –New Tin free products have had variable performance but has now improved –Foul release coatings, similar experiences –Conditioning coatings require in water hull cleaning 23Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

24 Assessment of hull performance This is a complex process Software available and services offered. Daily fuel consumption is probably adequate and a moving average acceptable May not be as sensitive as computer tools. 24Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

25 Cargo Oil Tanks Likely follow a similar pattern to WBT Draft regulation draws heavily on WBT regulations. Testing awaiting confirmation Lloyds maritime Academy 28/29 Feb 2010 Copyright Safinah Ltd

26 Future More inspection and verification –More cost on coatings –More repairs Need to get better through life data on coating performance Other regulatory changes may prevent long coating life Current regulations may inhibit innovation. Vessel design Novel maintenance contracts through life Link new build budget to operational budget 26Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

27 Projects looking forward BESST - Process BEKAS – Edge preparation Safinah KTP - Design Equivalent/alternative schemes under IMO PSPC – Japan/Holland/Brazil 27Lloyds maritime Academy 28/29 Feb 2010 © Safinah Ltd 2010

28 Conclusions Will need to develop proper maintenance regimes. Regulatory push will increase through life costs initially Need to revise how specified Need records Need to re-consider design Lloyds maritime Academy 28/29 Feb 2010 Copyright Safinah Ltd

29 Conclusions Going to get much worse before it gets better. Lloyds maritime Academy 28/29 Feb 2010 Copyright Safinah Ltd
