Samsung Heavy wins AiP for LNG carrier with wing sails

The Liberian Registry, the world’s largest registry, and the Korean Register (KR) have granted Approval in Principle (AiP) to Samsung Heavy Industries (SHI) for the basic design of a wing sail-equipped LNG carrier. The wing sail, an eco-friendly auxiliary propulsion system, generates thrust through lift created by the pressure difference between the upper and lower sections of its wing structure, resembling the form of a sail.

In addition to the wing sail, the design features a forward bridge...

VIDEO: Chemship retrofit is a wind-assisted propulsion world first

Ventofoil wing sail fitted to Chemship tanker

Chemship’s 2015-built 16,111 dwt Chemical Challenger has become the world’s first chemical tanker to be retrofitted with wind-assisted propulsion. This week, four 16-meter-high aluminum Econowind Ventofoils wing sails were installed on board the 134-meter long vessel, which serves Netherlands-headquartered Chemship’s transatlantic route between the East Coast of the United States and the Mediterranean.

The VentoFoils fitted to the Chemical Challenger have a direct wind surface of 180 square...

ABS publishes wind-assisted propulsion guide

The newly-published ABS Guide to Wind-Assisted Propulsion System Installation provides class safety standards for the installation of wind-assisted systems. It is applicable to two leading wind-assisted propulsion technologies: Flettner rotors and wing sails, including both rigid and soft sails.

“Wind-assisted propulsion systems, which use wind thrust to reduce vessel fuel consumption have real potential to contribute to industry decarbonization objectives,” said Patrick Ryan, ABS Senior Vice...
