OutSail Shipping - Containerized Sails for Cargo Ships

OutSail Shipping: Revolutionizing Maritime Freight with Containerized Sails

The shipping industry faces a pressing challenge due to new emissions regulations imposed by the International Maritime Organization. In response, shipping lines are exploring ways to reduce emissions and operating costs. OutSail Shipping, a start-up founded in 2022, aims to address these challenges by introducing containerized sails for cargo ships. In this article, we will delve into the innovative solution offered by OutSail Shipping, highlighting its advantages and potential impact on the shipping industry.

The Current State of the Shipping Industry

The shipping industry plays a vital role in global trade, but it is also a significant contributor to greenhouse gas emissions and air pollution. Maritime shipping burns a staggering 300,000,000 tons of fossil fuels annually, resulting in approximately 3% of global greenhouse gas emissions and 60,000 pollution-related deaths per year. Additionally, fuel expenses can account for up to half of the operating costs for cargo ships, which have been rising and are projected to continue increasing in the coming decades.

Furthermore, with shipping demand expected to double by 2050, it is evident that current steamship lines lack viable plans to decarbonize their operations. The industry requires an innovative solution to reduce emissions, minimize costs, and meet the growing demand for maritime transportation.

The Innovative Solution - Containerized Sails

OutSail Shipping proposes a groundbreaking solution to address the challenges faced by the shipping industry. By leveraging wind energy, OutSail aims to revolutionize maritime freight and create a more sustainable future. The company's product is a high-performance wing sail that can be installed as easily as a standard shipping container, offering a plug-and-play solution for cargo ships.

Traditional wind-assist devices have faced limitations, including their inability to fit on container ships and their limited performance at speeds exceeding 12 knots. Retrofitting existing vessels with these devices also incurs significant costs. However, OutSail Shipping's containerized sails overcome these obstacles, enabling shippers to save up to 20% of their fuel consumption without the need for expensive retrofitting.
