The length extension project follows the similar extension of Boskalis‘ hopper dredging vessel Prins der Nederlanden, which was conducted in the first half of 2022.

The conversion involved a mid-section restructuring by insertion of a new 45-metre middle section block, resulting in a capacity increase to 21,000 cubic metres for dredging sand storage.

According to Praxis Automation, part of the conversion also included a mid-life update of the existing vessel automation system.

The existing Praxis Mega-guard Pro-series was replaced by the latest E-series Mega-Guard, offering greater data communication capabilities using a redundant 100 Mbps fast-ethernet backbone.

The transition to the E-series resolved the physical range limitations of CAN technology and the modular design of the Mega-guard system provided the flexibility required for system expansion.
