Through Jotun’s Hull Performance Solution (HPS) and the DNV GL’s ECO Insight solution, a process has begun to collect and analyse data related to hull degradation. Advanced hull and propeller coatings are widely accepted as an effective preventative measure. However, as yet, there is no industrial consensus as to which solution is the most effective or how often propellers need to be cleaned.
“Our Hull Performance Solution (HPS) combines state-of-the-art hull coatings and application technologies with ISO-CD-19030-2 compliant performance measurements and high performance guarantees – helping customers reduce fuel costs and emissions by up to 16 per cent,” said Stein Kjølberg, global sales director at Jotun Hull Performance Solutions.
While Jotun is widely regarded as an industry leader in this field, and rightly so, this cooperation is about more than proving the merits of a single product. Rather, this initiative is aimed at proving the relative merits of a number of products. Being the first company to make the steps towards transparency and comparative analysis can only paint Jotun in a positive light – transparency is not a reality that inferior products will welcome and time will tell those who shy away from genuine competition.
As Niels Leikvang the partner manager for ECO Insight explained, “We are a classification institution, we do not do third party endorsements. We are however in a process of working with the ISO standard CD-19030-2 - a standard that will provide an even playing field for data collection.”
Leikvang continues to explain that although companies are willing to inundate customers with immeasurable quantities of data and spiel, data does not necessarily tell the whole truth. A brief glance at almost any political or economic entity will support the validity of this statement. In an industry much maligned for its opacity from both within and beyond the market itself, the establishment of unflappable structures can only be a good thing.
DNV GL will provide Jotun with hull and propeller performance computations based on computational fluid dynamics (CFD) models that include the complete operational range of the vessel.
“This approach generates a much greater amount of baseline data than a conventional model tank test could deliver and provides customers with the information they need to prove that they reduced both fuel consumption and emissions to charterers for example,” explained Dr. Torsten Büssow, DNV GL’s Head of Fleet Performance Management. ECO Insight computations also show how much resistance is added over time due to hull fouling.
DNV GL is also in participation and discussion with a number of other market players to develop an internationally recognised standard.
