NYKCOOL AB selects VVOS

The decision to fit VVOS on the ships was made by NYKCool following an extensive sea trial that as per Jeppesen revealed a measurable improvement in fuel conservation, seakeeping and schedule integrity over existing weather-routing products and services NYKCool tested. The ship officers utilized both the on-board VVOS program and Jeppesen Marine’s 24/7 routing guidance center during the trial.

The complete solution Jeppesen Marine will install on the ships includes an on-board VVOS workstation connected to the ship’s communication network, a solid-state motion sensor to monitor and record ship motions, and an office program for fleet tracking, performance analysis, and monitoring. As additional support, Jeppesen Marine provides unlimited 24/7 route and meteorological guidance from its Alameda, Calif. office where naval architects are available to resolve technical questions and confirm the integrity of the planned route.

VVOS incorporates sophisticated hydrodynamic modeling computations, together with advanced ocean forecasting tools, to recommend optimum speed and heading to minimize ship motions and reduce damage to the vessel and cargo, while maintaining schedule integrity. VVOS uses a detailed model of the ship’s motion, engine and propeller characteristics to predict the ship’s speed-over-ground and roll/pitch motions under forecast wind, wave and ocean current conditions for a given engine power and propeller RPM. While underway, VVOS provides ongoing monitoring and alarms for excessive motions and accelerations including parametric roll.
