Damen Receives 1st 3D Classification Approvals

After the initial end-to-end experiment with a dredger vessel proves efficiency advantages and time savings, Damen Engineering will use 3D Classification for more designs.

In partnership with renowned classification organization Bureau Veritas (BV) and top marine software vendor NAPA, Damen Engineering has announced the completion of its first vessel design that was developed, examined, and class-approved using 3D models.

The 2500 m3 dredger idea is the first Damen vessel concept to be certified by BV utilizing 3D model-based classification approval (3D MBA), a procedure in which class societies assess and approve designs using 3D models rather than 2D drawings, which is the standard at the moment.

Damen has stated that the process is already being used to create more designs, such as a 1000 m3 and a 4000 m3 hopper dredger, in the wake of this 3D MBA implementation’s success.

NAPA’s state-of-the-art technology supports these 3D model-based designs and approvals, allowing Damen and BV to collaborate on the same 3D model throughout the design and review process.

Kasia Romantowska, Managing Director of Damen Engineering Gdansk, part of the Offshore and Specialized Vessels Division of the Damen Group, commented: “We have been using NAPA’s 3D design tools for a long time and being able to go through classification reviews and approval on the same 3D model is a game-changer.”

Implementing a 3D MBA has shown excellent results since the first project, facilitating communication and saving time.

Notably, 3D MBA eliminates a significant source of potential errors because Damen no longer has to convert the 3D models it uses to build vessels into 2D drawings for class approvals and back into 3D to put the changes into place.

“Implementing 3D models throughout the design and approval processes of new ships is the way of the future, unlocking a new level of collaboration and information-sharing in the ship design process,” said Mikko Forss, Executive Vice President at NAPA Design Solutions.

“This creates a win-win situation that helps teams innovate together, enabling them to make the most of time and resources to deliver the best possible designs,” Forss remarked.

This initial approval is the result of a collaboration between NAPA and Bureau Veritas to implement 3D model-based approvals using an impartial OCX file format produced by NAPA Designer that BV can use to perform its prescriptive rule checks and calculations using its tools MARS and VeriSTAR Hull.

“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,” concluded Laurent Leblanc, Senior Vice President of Technical & Operations at Bureau Veritas Marine & Offshore.
