Singapore-based ONE takes delivery of methanol- and ammonia-ready boxship

Imabari Shipbuilding recently said it delivered 13,900 TEU container ship ONE SIMPLICITY  to Singapore-based container shipping company Ocean Network Express (ONE).

The vessel is designed for future fuel conversion to methanol and ammonia as well as the installation of onboard carbon capture systems. It has obtained an Approval in Principle (AiP) from the classification society Lloyd’s Register. 

“In addition, to comply with sulphur oxide (SOx) emission regulations and nitrogen oxide (NOx) emission regulations, we have installed a hybrid exhaust gas purification system (EGCS) and an exhaust gas recirculation system (EGR),” it said.

Using the latest analytical technology, we have developed an optimal hull shape that pursues high efficiency to match the frequently used ship speed and draft. The vessel has energy-saving devices, a twist rudder, and hull coatings that reduce friction to improve fuel efficiency.  

As a result, the shipbuilder said the reduction rate of the vessel’s CO2 emission reduction index (EEDI) from the regulatory standard value is approximately 60%, which is significantly higher than the latest requirements.
