The innovation team Wärtsilä has actually presented its newest growth based upon the used Computational Fluid Dynamics (CFD) designing to allow the exact as well as fast setup of thrusters as well as various other propulsion systems, to supply the optimum vibrant placing remedy. The brand-new Wärtsilä OPTI-DP Engagement Tool, which has actually been validated by DNV Maritime has actually been created in reaction to the enhancing requirement for reliable high-performance terminal maintaining as well as manoeuvrability as overseas procedures come to be much more intricate.

Conventional approaches for analyzing exact DP capacity estimations have actually come to be progressively tough as overseas procedures relocate even more from coast, as well as the vessels offering them come to be bigger as well as much more intricate. OPTI-DP enables the simulation of ecological operating problems, with independent wind, wave as well as present instructions, if wanted, plus the capacity to imitate several failings.

The Wärtsilä remedy takes into consideration all information of a vessel’s thruster as well as propulsion efficiency, consisting of the advantages of the 8-degree slanted thruster services, as well as makes use of CFD results to supply a precise evaluation.

Any adverse effect from communication in between the thrusters, various other propulsion systems as well as, for instance, jack-up legs can be reduced. Furthermore, the system can suggest any type of variety of prohibited areas to suggest undesirable communication in between thrusters. The outcomes of efficiency assessments exist in clear, thrust-utilisation polar stories for provided ecological problems or optimum appropriate wind rate stories.

“The independent DNV verification found that the Wärtsilä OPTI-DP Engagement Tool meets the requirements of the DNV standard ST-0111 Level 1, Level 2, and Level 2-site without thrust ventilation loss impact. These set requirements for analysing the station-keeping capability of a vessel in DP operations based on the static balance of environmental forces and the vessel’s actuator forces,” claims Luca Pivano, Principal Specialist DP Simulations, Control Systems as well as Cybernetics Advisory at DNV Maritime.

“The OPTI-DP Engagement Tool is a valuable breakthrough that will improve the safety and efficiency of vessels that require efficient and safe DP capability. By allowing an optimised propulsion configuration based on thrust performance, we can now accurately predict the station keeping capability of a vessel, which allows for maximum utilisation of the vessel operating in challenging weather conditions,” claims Lauri Tiainen, Director, Thrusters & & Propulsion Control Systems, Wärtsilä Marine Power.

The remedy enables the application of azimuth thrusters, passage thrusters, as well as propeller-rudder mixes, with outcomes readily available in hrs instead of weeks. The provided precision as well as effectiveness gains are matched with minimized financial investment as well as functional expenses.
