How digital solutions create real savings in the marine industry


At the prestigious Marine trade show Nor-Shipping in Oslo customers were looking this month for anything presented with one of two “D’s” in front of it: ‘Digital’ or ‘Disruptive’ and ideally both. AkzoNobel, with its leading brand International®, is an enthusiastic part of this trend. We launched our ‘Digital Voyage’ concept including four new digital […]

Propeller performance and coatings


Propeller performance plays an important part in a vessel’s operation. The main causes of propeller deterioration are corrosion, impingement attack, cavitation erosion, and fouling. Corrosion is minimized by constructing propellers of corrosion resistant alloys such as Nikalium and Superston. Impingement attack usually occurs at the leading edge and outer part of the propeller blades. Cavitation […]

How important are water ballast tanks for ship owners?

Water Ballast Tanks

The condition of the water ballast tanks can affect both the safety and structural integrity of the vessel and also reduce its asset value. Water ballast tanks are an integral part of every ship and although these areas are not revenue earning, they can be critical particularly if steelwork replacement as a result of corrosion […]

Which is the best fouling control coatings technology? More than 40 years of “big data” gives the answer

Ever since mankind first set sail there has been a need to protect vessels against the natural onslaught of marine biofouling species. Over the centuries an array of solutions have been investigated with varying degrees of success, from cladding ships’ hulls with copper plate to coatings based on exotic chemical concoctions delivered as a lacquer […]

Dataplan Revisited


In 1974, some inspirational scientists, at what was then International Paints (now AkzoNobel’s Marine Coatings Business), set up a database to collect information on the performance of the company’s fouling control coatings.  The database, called Dataplan, was designed with simplicity in mind, and grew unabated for almost 30 years. Dataplan ultimately grew into “big data”; […]

Do shipowners realize the benefits of investing in sustainable solutions?


On May 28th 2015 the Dutch “Financieele Dagblad” published an article on AkzoNobel’s successful launch of the first ever carbon credit methodology in the maritime industry. Linked to our company’s eco-friendly antifouling coatings Intersleek®, the scheme provides an additional financial incentive to shipowners to upgrade to sustainable solutions.  However, as the maritime industry is going […]

Intersleek upgrade pays off on high-speed ropax ferries in Australia


Two high-speed ferries owned and operated by TT-Line Company Pty Ltd, which run between Australia’s Port of Melbourne in Victoria and Devonport in Tasmania, have had a series of hull coating upgrades which are paying off in terms of improved efficiency and lower maintenance requirements. One of the ferries has already had her hull coated […]
