Improving Crew Safety in Handling Methanol as a Fuel

Focus Area: Maritime Green Technologies

Overview

Methanol is gaining traction as a low-carbon fuel for the maritime industry, with new methanol-fueled ships and bunker barges being introduced. In July 2023, Singapore completed the world's first methanol bunkering operation with a containership, and such operations are set to expand globally. Ensuring the safety of crews handling methanol with the latest safety technology is crucial.

Importance

  • Methanol is highly flammable and toxic, with invisible flames.
  • Its faint alcohol odor is detectable only at 2000 ppm, ten times the safe limit.
  • Methanol's flammability poses higher risks compared to traditional fuels.
  • Singapore's frequent lightning strikes raise concerns about methanol fume ignition during bunkering.

Market Potential

  • Relevant for crews on methanol-fueled vessels and bunker barges, estimated to reach 1,200 ships globally by 2030.
  • Terminal workers and truck operators involved in bunkering will also face similar challenges.

Current Efforts

  • Personal gas detectors currently measure only limited types of gases and concentrations.
  • Existing sensors are primarily designed for petrochemical plants, not for maritime use.

Solution Criteria

  • Must be cost-effective.
  • Should detect methanol vapor leaks and invisible flames.
  • Needs real-time functionality, considering possible limited onboard connectivity.
  • Should alert crew and/or ship managers before entering high-risk areas.
  • Must be suitable for maritime conditions and easy to maintain.

Potential Solutions

  • Comprehensive sensing systems and networks for detecting methanol leaks.
  • Technologies to mitigate methanol fume dispersion from vessels.
  • Vapor return systems for bunkering to capture methanol fumes.
  • Robotics for ship operations, particularly in enclosed spaces.
  • Metaverse training for crew to increase awareness of safety measures.
  • Improved ship designs to reduce methanol leakage.
  • Video analytics to detect methanol leaks.

These solutions will enhance safety and sustainability in the maritime industry, promoting methanol as an eco-friendly fuel.
