Our activities

Farwind Energy designs and manufactures rotor sails, and supports shipowners and shipbuilders throughout the entire ship lifecycle, from the preliminary design phase to onboard integration: performance study, impact study, structural analysis, energy management and system interface.

During feasibility studies, the optimal rotor configuration is determined by integrating onboard energy management objectives.

Farwind Energy also provides maintenance services throughout the sail life cycle.

5 steps to save fuel and make your project a reality

Stage 1
\
Initial contact and preliminary study

Get in touch with us and we’ll carry out a free preliminary study for you, giving you an estimate of the expected savings and payback period.
All you need to do is provide us with some general information about your fleet, sailing areas and time spent at sea.
Our in-house performance prediction tool is based on over 20 years of statistical weather data.

Stage 2
Optimum configuration selection

We then carry out a detailed analysis to select the optimum overall arrangement for your vessel.
This involves selecting the number, size and location of rotor sails best suited to your vessel and activities.
The selection takes into account several general and vessel-specific factors, including:

  • Safety and operations – Air draft (decks), port operations, etc.
  • Maritime regulations – Visibility from the bridge, radar and navigation lights, stability, etc.
  • Geometry and structure – Available deck space, existing deck equipment and piping, deck-hull structure for foundation installation, etc.
  • Aerodynamic interference – between sails, with ship superstructures and other deck equipment.
Stage 3

Integration studies and class agreement

Once the preferred sail configuration has been selected, a detailed project for modernizing the vessel is drawn up.
The final document includes three main dimensions:

  • The structural aspect, including the rotor pedestal and any local deck reinforcement.
  • Electrical and control aspects, including electrical circuit diagrams and rotor consumption profiles in relation to the auxiliary power available.
  • Detailed analysis of bridge visibility, navigation lights and stability.

The documentation generated by the modernization project is submitted to the classification society and flag state for approval. This confirms compliance with all applicable regulations.

Stage 4
Ship preparation

Before the sails are received, the ship is prepared.

We provide supervision services throughout the integration phase, according to your needs. In the case of a retrofit, this work is scheduled during a periodic or special survey, so as not to disrupt the ship’s operations. New-build integrations are carried out during the construction program.

This work includes :

  • Installation of the pedestals on which the rotor sails will be mounted.
  • Integration into the sails’ electrical and control network via electrical and data cables. The sails are connected to the gateway. An automated system manages the sails, and the officer of the watch has direct control.

This preparation takes place in hidden time compared to the duration of the dry dock (work of the order of one to two weeks).

Stage 5
Rotor installation and commissioning

Rotor sail installation is straightforward, and is usually completed in a single day.

The rotors are delivered to the quayside, ready for installation. Installation takes place in a single lift. The rotor is connected to the foundation on the ship’s deck. Wiring connections are made, and the ship is ready to go.

This operation can be carried out in the same dry dock where the vessel is being prepared, or afloat during any other regular port of call.

post-commissioning operational support

Rotor sails are automated. They do not require any specific training for the team.

We offer a hands-on training session to help you get the most out of our systems.

We also provide technical support for sailors.

Training

The use of Farwind rotor sails requires minimal intervention on the part of the crew. However, to ensure maximum benefit and understanding of the equipment, Farwind provides comprehensive training for both crew and shore-based technical services.

All our rotors are automated and react to wind conditions to maximize performance without the need for crew intervention.
All safety devices, stops and alarms are automatic.

Data Analysis

Farwind carries out in-depth analysis of environmental and performance data. This data forms the basis of our in-house research and development. Both the onshore prototype and the offshore installations collect data under a range of demanding environmental and operational conditions. Fawind’s expertise in data processing and analysis enables us to provide you with reports such as:

  • Real-time data acquisition from ship to shore
  • Performance reports
  • Condition-based maintenance (CBM)
  • Advice on optimizing machine performance

Maintenance

Farwind offers full support for the 25-year life of rotor sails. This support ensures that rotor sails stand the test of time and benefit from technological advances in the industry.
Life-cycle support includes the following:

  • Remote assistance and troubleshooting
  • Spare parts
  • Software updates
  • Advanced data analysis
