Dutch container ship owner JR Shipping is set to retrofit another six of its feederships with carbon-capture systems.

The move is expected to leave the company with eight vessels of between 750 teu and 1,440 teu fitted with emissions-reducing technology.

The Harlingen-based company currently has two vessels equipped with the technology: the 750-teu Endeavor (built 2005) and Energy (built 2004).

Now the company has signed a deal with Rotterdam-based technology provider Value Maritime to retrofit six ships.
