Anemoi has developed a Fuel Saving Assessment Model bound4blue to install four suction sails on the Crimson King- dom. The 229-m Panamax bulk carrier will be retro? tted in (FSAM) to predict fuel and emissions savings from various 2023/24 with four 26-m eSAILs, expected to be the largest sizes and classes of vessel. Central to FSAM are four key data suction sails ever built and installed on a vessel. sets which are: Rotor Sail performance data (harvested from

Anemoi’s full-scale UK test facility), vessel performance data, route data and wind data. FSAM uses this data to simulate thousands of historic voyages over a ? ve-year period to en- sure the results accurately re? ect the wind conditions experi- enced on the chosen route. Any additional drag and increased generator usage are also included so that the net results are fair and transparent.

For a 310,000-dwt VLCC trading the Bonny-Ningbo route and ? tted with ? ve Rotor Rails, FSAM predicts an annual fuel and emission saving of 13.5% which equates to 1,622 tons of

Sail itself, the Foundation, Deployment System (if required), solution, currently in development. Patent-pending, AirWing is wind sensors and Electrical, Control, and Automation sys- designed to help ships produce between 10% - 30% fuel sav- tems. The main components of the Rotor Sails are the “Rotor” ings for retro? ts and even greater savings for newbuilds. (the cylindrical, rotating part), the support Tower, upper and lower bearings, and the electrical drive system.

The Rotor is built from lightweight composite material and the Tower is a steel column structure.

The Rotor Sails have a control station located on the bridge which automatically controls the speed and direction of the

Rotor Sails, as well as monitoring the performance and status of the system. The control system is designed to maximize performance and minimize crew input with automated speed and direction setting, equipment monitoring, safety features
