ClassNK has granted approval to the basic design drawings of a multi-purpose container carrier developed by Nippon Yusen Kabushiki Kaisha (NYK Line) utilizing 3D models.This marks the world's first ocean-going ship to complete the basic design process, including class approval, solely through 3D drawings from the conceptual design to the basic structural design, during the initial stages of ship construction, according to NYK Line and ClassNK.Traditionally, the sharing of design information among shipyards…

On March 28, NYK received approval for 3D drawing (3D Model-Based Approval) from ClassNK of the basic design of a new multi-purpose container vessel.This is the first time that the entire basic design process, including classification approval, using only 3D drawings, has occurred for an ocean-going vessel, according to NYK and ClassNK.Currently, 2D drawings of the structural design of new ships are commonly shared between shipowners, shipyards, shipping companies and classification societies.

Big data, advanced computers and AI are allowing vessel designers to prepare models that leave essentially nothing to chance.“Lastly, it may be of considerable importance to form from the draught a block model of the vessel from which a still more accurate judgment may be formed of the fitness and beauty of the body. And should any defect be discovered, farther alterations must still be made, till the draught and the model are perfectly approved of. These different alterations and repeated calculations may appear very tedious…

The competitive landscape in shipbuilding has changed dramatically, as ‘Industry 4.0’ capabilities driven by the digital revolution have given the edge to those that scout and adopt solutions that deliver on the promise of increasing efficiency while cutting costs. Juan Prieto discusses the CADMATIC suite of solutions for North American shipyards seeking to capture the competitive edge.Digital technologies are evolving at breakneck speed, unlocking tremendous efficiency gains for shipbuilders.

Demand for data that can inform strategies for asset management and performance monitoring is driving the wider adoption of digital tools in shipbuilding. Vessel designers are increasingly able to employ a software-driven approach that creates efficiencies and satisfies compliance.Shipowners want visibility on assets over their lifecycle, and as the era of planned maintenance routines gives way to predictive interventions, shipyards are turning to 3D models to create digital twins…

Bureau Veritas (BV), the Shanghai Merchant Ship Design & Research Institute (SDARI) and NAPA have completed the first phase of a Joint Development Project (JDP) to enable 3D model-based approvals for the classification of ships. The project validated the feasibility of 3D model-based approvals where classification reviews are directly based on the 3D model provided by the designer, rather than requiring multiple conversions to 2D drawings, which is the traditional process. The objective is to boost efficiency in the design process…

More than remote witnessing, more than remote data analysis, remote survey techniques are now going to aid the shift to full vessel autonomy.The technology that enables a robot to safely navigate an environment it has no prior knowledge of is called Simultaneous Localization and Mapping (SLAM). “It is the key to autonomy for any aspiring can-do inspection robot.” That’s according to ScoutDI, a participant in the REDHUS project led by DNV which is developing a prototype inspection drone.SLAM is not a specific, copyrighted piece of technology.

Herbert-ABS Software Solutions released its Herbert-ABS Wind program, touted as a regulatory wind and overturning moment calculation tool that can be provided as a stand-alone application, or as part of the larger HECSTAB design and regulatory assessment software suite.Leveraging extended modeling capabilities from the HECSTAB Ship Project Editor, or HECSTAB Rhino plug-ins, anyone can define a 3D model representative of a vessel’s topside structures. Once a model is complete, Herbert-ABS Wind can perform calculations for wind force and overturning moments used in design and regulatory approval. Herbert-ABS Wind allows naval architects to evaluate relevant regulatory requirements for floating structures…

Upgraded data linkage designed to enable the seamless flow of information between design and class approval software, reducing time spent on information transfer by 30% and fostering closer collaboration.NAPA and ClassNK recently fortified their partnership to support the use of 3D models in the ship design approval process by streamlining data sharing between design and class approval software. “As the capabilities of 3D computer-aided design software improve, we see an acceleration in the use of 3D technologies in the shipbuilding industry," said Dr.

3D digital design can save ‘dollars on the deck plate’ during construction while maintaining safety, says to Patrick Ryan, Senior Vice President, Global Engineering and Technology, ABS.Last year ABS, Robert Allan, Signet and USCG collaborated on a project that would be the first commercial vessel in U.S. history to be produced using only 3D models in design and construction for all structures. While the process used to deliver this RAL-designed Advanced Rotortug (ART) is historic…

Maritime software, services and data analysis provider NAPA and testing, inspection and certification group Bureau Veritas (BV) are partnering to enable more effective and widespread use of 3D models in the class approval process.The two parties said they seek to improve the overall efficiency and accuracy of future vessel design and solve the current challenges associated with 2D drawings. While naval architects use 3D models to design ships, the assessment of these designs by class ensure they meet relevant safety and compliance specifications…

There is an old adage that states that a repair yard can economically build new ships, but a new construction yard should never touch ship repair jobs. In my experience there is a lot of truth to that statement, and it does not mean that new construction yards are run by less capable people; it simply means that ship construction and ship repair and conversion are fundamentally different business models. Ship construction uses a script, while ship repair and conversion is improvisation. I will not drive the theater comparison completely home, but it has some validity.
