• Hull performance refers to impact of hull on the fuel efficiency of a ship
• Deterioration in hull & propeller performance between dry-dockings
currently accounts for around 1/10 of world-fleet fuel costs and GHG emissions
• Implications:
~ 20-30 billions in additional fuel cost
~ 0.3% increase in man-made carbon emissions
Hull performance – a ship efficiency killer

PAINT MAKER’S DILEMMA
LACK OF MEASURABILITY!
IF I CAN’T MEASURE A RETURN, AN EXTRA INVESTMENT HAS
NO VALUE!
OWNER’S DILEMMA
Why does performance remain poor?
SK / HPS / 9th Chemical and Product Tanker conference / London 2017-03-145
• As a part of our Hull Performance Solutions Jotun developed and launched own measurement method in 2011
- JHPMM
ISO 19030
• Asked to join in a call for an International standard to make JHPMM available as a starting point for work on same
• Became convinced of the benefits of /
need for a commonly agreed upon measurement method
- Reliability
- Comparability

How can this benefit the chemical and tanker industry?
• An ISO standard for Hull and Propeller performance is now in place
• Could a similar idea for cleaning and coating of tanks help the industry move forward?
“Increasingly strict tank cleaning standards required by charterers are also being addressed. Such requirements result in over-cleaning and a subsequent waste of fuel, energy and time, as well as increased costs and an impact on the environment. The Committee is working on the production of a set of cleaning standards which could be deployed as an industry standard.”
• How about the selection of the correct coating product?
− On what basis are charterers or owners making their decisions?
− Could a similar approach help the industry make better decisions?
