First 3D classification approvals for Damen ship design

The 2500 m³ dredger concept is the first Damen vessel concept to receive BV certification using 3D model-based classification approval (3D MBA).

The process allows class societies to review and approve designs using 3D models rather than 2D drawings, as at present. Following this successful implementation of 3D MBA, Damen has confirmed that the process is already being applied to further designs including a 1000 m³ and a 4000 m³ hopper dredger.

By using NAPA’s technology, Damen and BV can work collaboratively on the same 3D model throughout the design and review process. The deployment of 3D MBA has yielded positive results, streamlining communication and saving time. The use of 3D MBA also eliminates a major potential source of errors, as Damen no longer needs to translate the 3D models it uses to design vessels into 2D drawings for class approvals, and then back again into 3D to implement the changes. 

This first approval follows a partnership between NAPA and Bureau Veritas to implement 3D model based approvals using a neutral OCX file format generated by NAPA Designer that enables BV to perform its prescriptive rule checks and calculations utilizing its in-house tools MARS and VeriSTAR Hull. 

Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas Marine & Offshore, said: “We are delighted to deliver this approval for Damen’s 2500 m³ dredger concept which is the result of our collective determination to make 3D model-based approvals a reality in our industry. This milestone demonstrates the effectiveness and viability of 3D MBA to support closer and more efficient collaboration between designers and our classification surveyors while ensuring that all safety and regulatory standards are met. This collaboration with NAPA and Damen is a tangible demonstration of BV’s commitment to work with pioneers in our industry, supporting the safe innovation needed to meet the safety and sustainability challenges ahead.”
