ISO 19030Scope and implications for buyers and sellers of performance enhancing technologies and solutions

London, 14th March 2017Stein Kjølberg – Global Sales Director HPS


• 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?


• 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

Part 1: General principles Part 2: Default method Part 3: Alternative methods

• Outlines general principles

• Defines a set of basic performance indicators for hull and propeller maintenance, repair and retrofit.

• Defines the default method for measuring changes and calculating the basic performance indicators

• Describes the expected accuracy of the basic performance indicators.

• Defines a set of alternative methods for measuring and calculating the basic performance indicators

• Based on typically available measurement infrastructure.

What next?


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?
