Container carriers are leading the way in adopting bow windshields to cut fuel use.

Germany’s Hapag-Lloyd is the latest container line to add bow windshields, with Alphaliner posting images of a new mega-ship under construction in South Korea sporting a large, arch-shaped windshield on its bow. Other Hapag-Lloyd vessels under construction in China will also be fitted with similar devices.

Ocean Network Express (ONE) and CMA CGM were the first to reintroduce windbreaks, followed by Mediterranean Shipping Co.

Norasia, a container line eventually acquired by CSAV and then merged into Hapag-Lloyd, has been installing smaller bow windbreaks on a series of vessels built about 20 years ago.

“These devices will reduce the ships’ aerodynamic resistance and thus help lower the fuel consumption and emissions. While the effect of wind deflectors is small at around 2%, little improvements on hull, propeller, engine, etc. add up to notable savings,” Alphaliner noted in its most recent weekly report.

“Despite their rather limited energy-saving potential, bow windscreens have become a popular option for newbuildings and retrofits,” Alphaliner noted. “This is because they are low-hanging fruit when it comes to emissions reductions and they require virtually no extra maintenance once installed.”
