New guidelines support safe uptake of wind-assisted propulsion

The Maritime Technologies Forum, supported by BIMCO, has released comprehensive new guidelines to enhance the safety management systems of vessels utilizing wind-assisted propulsion systems (WAPS). As shipping companies increasingly adopt rotor sails and suction wings to meet decarbonization targets, these protocols address critical operational risks. The guidance focuses on mitigating hazards associated with mechanical failures and structural integrity during heavy weather, ensuring that modern wind-propulsion technology aligns with the rigorous safety standards expected in global merchant shipping today.

These guidelines are essential for compliance departments navigating the complexities of SOLAS Chapter II-1, which governs construction and machinery installations. By integrating WAPS into existing safety management systems, operators ensure adherence to the International Safety Management (ISM) Code. Furthermore, the documentation helps vessels maintain classification society requirements, such as those set by DNV or Lloyd’s Register, regarding stability and equipment maintenance. Aligning these systems with MARPOL Annex VI energy efficiency standards is vital for shipowners aiming to improve their EEXI and CII ratings while avoiding costly port state control detentions.

For masters and navigating officers, these guidelines necessitate a shift in bridge resource management and voyage planning. These officers must now account for the specific aerodynamic limitations of rotor sails during adverse weather conditions. Navigating officers are required to undergo specialized training to monitor wind-assisted propulsion performance and ensure that automated systems do not interfere with standard navigational safety protocols, ultimately ensuring that the vessel remains within its defined operational safety envelope at all times.
