Hull and propeller standard

Jotun Hull Performance Solutions has been asked to lead the work on the standard and will share its experience and data to identify a method.

Jotun says by improving hull and propeller performance, the world fleet can reduce fuel costs by as much as US$30bn per year and achieve an estimated 0.3% reduction in manmade greenhouse gas (GHG) emissions.

But the main barrier is reaching this has been a lack of an accurate and reliable method for measuring hull and propeller performance over time.

Geir Axel Oftedahl, business development director, Jotun Hull Performance Solutions, said: “If we are successful in reaching general agreement on a method for measuring hull and propeller performance, it will make a substantial contribution to the industry – and help align the interests of ship owners, charterers, ship builders and eco-technology providers such as Jotun.”

In cooperation with the Bellona Foundation and Standard Norway, Jotun has gathered together industry stakeholders in an effort to reach general agreement, which the company says is critical.

In preparation for work on the international standard, Bellona has submitted two proposals to the IMO’s Marine Environment Protection Committee (MEPC), and Standard Norway and Jotun have co-authored the New Work Item Proposal that has now been approved by the ISO.

Over the next six to 12 months, the ISO expert group will produce a draft standard.
