Classification society DNV GL has developed a new brochure to offer a set of best practices for the design of ships subject to NOx Tier III requirements. It also offers guidance on the considerations that should be taken into account at the newbuilding stage.

Rolls-Royce, The Norwegian University of Technology Science (NTNU), research organisation SINTEF Ocean, and classification society DNV GL have signed a memorandum of understanding (MoU) with the aim of creating an open source digital platform for use in the development of new ships.

The Chinese manufacturer SunRui and classification society DNV GL celebrated last week, as Sunrui became the fourth manufacturer of ballast water treatment systems (BWTS) to obtain type approval from the US Coast Guard (USCG). Its BalClor® system treats ballast water in three steps: Filtration, seawater electro-chlorination for disinfection and neutralization. The company is the first Asian manufacturer to be awarded the USCG type approval certificate for BWTS. As one of five independent laboratories accredited by USCG, DNV GL worked with SunRui on the testing of its BWTS.
