ISO Standard for Hull and Propeller Performance Would Generate Better Shipping Designs

Norwegian Triumvirate Presses Case for Collaboration from Industry Stakeholders
Shipping News Feature

NORWAY – WORLDWIDE – Any regular reader will know of the recent, intensive efforts made by ships designers and builders around the globe to maximise hull efficiency, a factor which can often reduce fuel use and emission production to rival the technological strides being made in engine design and other factors. Hull and propeller optimisation when designing container vessels and other shipping has become the Holy Grail for shipyards wishing to gain orders for ever larger freight carriers.

Now, three Norwegian based organisations are collaborating after the International Organization for Standardization (ISO) took action to mobilise a group of experts with the intention of producing a common industry standard for measurement of changes in hull and propeller performance. Hull coating specialists Jotun are cooperating with the Bellona Foundation, an international environmental NGO working with a team of engineers and ecologists and Standards Norway, the body responsible for standardisation in most technologies to the Norsk Standard.

The three principals say they have been successful in garnering the interest of shipping industry stakeholders in an effort to reach general agreement on a method for measuring changes in hull and propeller performance. The opinion is that lack of an accurate and reliable method for measuring hull and propeller performance over time has proved the major obstacle to realising the potential savings which the group says equates to as much as $30 billion per year and could achieve an estimated 0.3% reduction in global manmade greenhouse gas emissions annually.

In preparation for work on an International standard, Jotun has contributed to two proposals submitted by Bellona as a part of the Clean Shipping Coalition to IMO’s Marine Environment Protection Committee (MEPC). In cooperation with Bellona, Jotun has hosted two International workshops involving more than 40 experts representing relevant stakeholders. Finally, together with Standard Norway, Jotun has co-authored the New Work Item Proposal that has now been approved by the ISO.

Over the next 6 to 12 months, the ISO expert group will produce a draft standard and Jotun has been asked to lead the work and will share its extensive experience and data within the area of hull and propeller performance. Svend Søyland, Senior Advisor with the Bellona Foundation believes that a transparent and reliable standard is the catalyst which will generate innovation in the field and that that identifying overlaps between cost savings and reduced greenhouse gas emissions makes sense, whilst Geir Axel Oftedahl, Business Development Director at Jotun Hull Performance Solutions sums up, saying:

“Broad stakeholder involvement from the start to the end of this process is absolutely critical. Our objective is to win industry acceptance for a method for measuring changes in hull and propeller performance. To achieve this goal, we need to ensure that the standard delivers on the requirements and expectations of all relevant stakeholders. We are pleased to see that a number of other stakeholders have already agreed to contribute, and call on others with interests and capabilities within the area of hull and propeller performance to do the same.

“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.”
