US Navy coating solution show signs of slowing discoloration

A pigment package designed by the US Naval Research Laboratory to limit discoloration of the exterior coating on surface vessels, has began making its way into the fleet and is producing early, positive results. NRL researchers created the solution to meet the fleet needs for the Navy standard ‘haze gray’ paint that will remain color stable for longer than current coatings.

Hapag-Lloyd tests ship painting robots

In line with an overall tendency to automation, German shipping company Hapag-Lloyd is currently testing robots onboard nine ships, to improve ship painting and shorten the docking time. The shipyard staff works by hand on the bulbous bow, below the bilge keels, at the propeller apertures, and on the flat bottom.

Jotun signs with Hyundai Heavy for new, green marine paint

Greek marine coatings company Jotun announced it has signed a memorandum of understanding (MoU) with the world’s largest shipbuilder, South Korean Hyundai Heavy Industries (HHI), for a new type of marine paint that reduces solvent emissions by up to 90%. 

IMO: Need for more studies on coatings as new source of microplastics

IMO issued a report to assess current knowledge and data regarding marine coatings as microplastics sources, identifying very little practical research or knowledge on the topic. The IMO review came after a report by IUCN which showed that hull scrapings, marine coatings and anti-fouling systems are potential sources of microplastics in the oceans.

Identifying Professional Indemnity claims: Blistering coatings

In a recent publication, Andrew Hodkinson and Joel Thornton from Charles Taylors Adjusting, outline how an Engineering Loss Adjuster can team up with appointed lawyers to quickly identify the key issues in a P&I claim and determine how best to establish probable root cause, liability and quantum aspects. In their first case-study, they explore P&I issues surrounding blistering coatings.

Jotun: Key considerations when choosing antifouling coatings

In an exclusive interview, Mr. George Vranakis, Marine Manager at Jotun Hellas, discusses about the key challenges concerning antifouling, providing also tips to operators for choosing the right coating for the protection of their vessels’ hulls. Mr. Vranakis highlights that the right selection starts with the identification of the operational needs, while considering the technical issues after discussion with experts are also important. In this regard, Mr. Vranakis shares his insight on the suitable approach toward an antifouling coating that best fits the operational profile of vessels.

US Navy to develop fuel and energy saving coating

The US Navy informed that it is developing a new ship coating that will reduce fuel and energy costs. Namely, the Office of Naval Research is sponsoring work by Dr. Anish Tuteja, an associate professor of materials science and engineering at the University of Michigan, to create an omniphobic coating. This coating is clear and can be applied to numerous surfaces.

European Commission funds project to reduce ships’ frictional resistance

The European Commission granted a project which aims to develop a biomimetic hull coating that reduces the frictional resistance of ships. A team of ten European scientists and industry experts led by the Fraunhofer Center for Maritime Technologies and Services will receive a total grant of 5.3 million Euro to develop the AIRCOAT prototype.

Scientists develop new coating to reduce biofouling costs

A team of chemistry researchers from the University of Sydney Nano Institute has created nanostructured surface coatings that have anti-fouling properties without using any toxic components. The new coating uses ‘nanowrinkles’ which are inspired by the carnivorous Nepenthespitcher plant.

Green Award scheme welcomes new member

NanoPhos Marine, a company using nanotechnology to boost energy efficiency of ocean going vessels, became a Green Award incentive provider. Green Award has been certifying ships and ship managers that are superior to required values of the industry regulations for more than 20 years.
