Weather routing (VVOS)

Jeppesen Marine offers a range of services under the name Vessel and Voyage Optimization Solutions (VVOS). The system is an onboard passage planning tool and a seakeeping expert advisory system.

VVOS software is custom tailored to each vessel class class in order to provide accurate predictions of the ship seakeeping and speedkeeping capabilities in any seastate. The VVOS seakeeping advisory module shows the effect of changing heading and speed on vessel roll, pitch, accelerations, slamming, boarding waves, bending moment/shear forces on critical frames – thus helping officers avoid heavy weather damage. An optimization algorithm can also minimize fuel costs.
