On August 2, TSUNEISHI SHIPBUILDING (HQ: 1083 Tsuneishi, Numakuma-cho, Fukuyama, Hiroshima, Japan; President: Sachio Okumura) released the details of the new model TESS66 AEROLINE on its website.

Spurred by an increase of cargo volume, ships in the shipping industry are increasing in size in pursuit of transportation efficiency per voyage. With enhanced demand in recent years to address global warming, the growth in size is accelerating from the perspective of reducing CO2 emissions per transportation unit as well.

Furthermore, its outstanding versatility ensures that customer convenience is not compromised as it maintains the Panamax breadth along with industry-standard depth.

With the features of fuel-efficiency and environmental performance, such as TSUNEISHI SHIPBUILDING’s proprietary AEROLINE technology that reduces wind resistance by approximately 20%, the ship complies with the CO2 emission regulations, EEDI (*2) Phase 3. The ship model has been refined for excellent fuel efficiency under all conditions, from shallow to full load draft.

Comment from Kazutaka Seki, Manager of Ship Planning Dept., Design Div.
“We hope this ship model will be a long-lasting favorite for its loading performance, fuel efficiency, environmental performances, and versatility that provide high added value to customers. We will continue to create globally-advanced products and provide ships that combine transportation efficiency with a reduced environmental burden.”
