Adding a new layer to shipping: DNV GL launches first class guideline for additive manufacturing

DNV GL has published the first classification guideline for the use of additive manufacturing (AM) in the maritime and oil & gas industries. The guideline is designed to help manufacturers and sub-suppliers of materials, parts and components, service suppliers and end users adopting AM technologies, by ensuring that the parts or components created by an AM process and the materials from which they are created have the same level of quality assurance as traditionally manufactured products.

D-Class Takes Shape with Houston Workshop

"Houston/New Orleans area is home to companies with deep DP experience and open mind to explore alternatives for modernizing processes aiming at higher efficiency and safety. All that was proven during an actively interactive one day workshop session at DNV GL Houston office where concepts were challenged and support to this initiative was stressed as the industry leading way forward”, says Sergio Garcia, Business Development Director at DNV GL - Maritime Americas.

Ballast water treatment – SunRui becomes first Asian manufacturer to win USCG type approval

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.

A twist in the tail: DNV GL adds asymmetric stern to ECO Lines hull optimization service

A vessel with an asymmetric stern has a twisted aft shape that is designed to account for the differing flow conditions on each side of the propeller. The idea emerged in the 1960s, but due to the difficulty of manually developing the optimal shape, this design failed to make a large impact at the time. DNV GL has revisited the idea and, using high-fidelity computer fluid dynamics (CFD) in combination with parametric formal optimization, the classification society can now offer ship owners the option of incorporating an asymmetric stern into their new vessels.

DNV GL launches new PSC Planner application

Classification society DNV GL has launched a new application on its My DNV GL portal – the Port State Control (PSC) Planner. The PSC Planner has been designed to help ship owners, managers and operators increase their operational efficiency by giving them an overview of a vessel’s or fleet’s PSC performance and to benchmark that performance against the IACS classed world fleet. It also helps the crew on board by showing them particular areas to focus on when they are preparing for their next inspection.

Getting the message: CMM and DNV GL undertake first class health check of on-board control networks

Classification society DNV GL teamed up with innovative Greek owner Consolidated Marine Management (CMM) for a test on the health of a control and communication network on board seagoing vessels. The pilot project, conducted on one of CMM’s state-of-the-art chemical tankers, investigated exactly what it takes to carry out a successful test of a vessel’s communication and control systems, in order to strengthen their overall robustness and resilience.
