Demonstrating an exceptional and unparalleled trial, Damen has proficiently completed comprehensive roll-over assessments of its Search and Rescue Vessel 1906 with operational engines. These assessments were conducted in Antalya, Turkey, in collaboration with the Turkish Coast Guard and the International Organization for Migration (IOM), as well as engine manufacturer MTU.
Since its inception, the Damen SAR 1906 has exemplified technological and educational synergy. For example, the pioneering design itself is the culmination of close cooperation between Damen and the Royal Netherlands Sea Rescue Institution (KNRM), Delft University of Technology, and De Vries Lentsch Naval Architects.
These recent ‘roll-over with operational engines’ assessments illustrate that now, nearly five years after the vessel was launched into the market, Damen continues to strive for enhancements to this award-winning design by incorporating findings from ongoing research.
Complete control
“This unique assessment with active engines was requested by the Turkish Coast Guard. This remarkable outcome has been achieved thanks to the outstanding collaboration among all involved,” states Damen’s Sales Manager Boran Bekbulat.
“Furthermore, we take great pride in asserting that this is the first occasion a roll-over assessment has been successfully executed with running engines. We extend our gratitude to the Turkish Coast Guard for challenging us to push our limits. Most importantly, this demonstrates the capabilities of the vessel for which she is designed, instilling confidence and control in her crew under all weather conditions.”
Roll-over functionality
In describing the sequence of events leading up to these successful trials, Meredith Dijkstra, Damen Product Portfolio Manager for High-Speed Craft, underscores Damen’s partnership with MTU: “We have been collaborating closely with MTU to develop and refine engine software capable of addressing a capsize scenario. This has been supported by engine roll-over assessments at their facilities and our own verified investigations into the roll-over capability of the SAR 1906.”
In the event of a vessel capsize under severe weather conditions, the capsize switch detects the roll-over and dispatches signals to, for instance, the engine software, which will then enter ‘roll-over mode’. “During this time, the water jets are automatically disengaged and the engine reverts to idle mode to protect its integrity,” she explains. “This continues until the software confirms the vessel has stabilized, allowing the crew to regain direct control.”
The SAR 1906 is also equipped with several mechanical design characteristics implemented to ensure the ongoing and safe operation of the engine. “We purposefully employed mechanical solutions instead of electronic ones due to their enhanced safety and durability.” Notable examples of the mechanical design features include the addition of extra water traps within the ventilation intakes and exhaust systems.
“After all, this is the principle we have been striving for; when other vessels are compelled to return to port due to adverse weather, the SAR 1906 must be capable of continuing her mission when no one else can.”
