3060

Hamburg-based shipowner Hammonia Reederei and Intermarine, a charterer from New Orleans has enabled the retrofit of three sister vessels with multiple efficiency technologies and revenue-sharing collaboration between the charterer and the owner.  Carbon War Room (CWR), a non-profit organization from the UK has officially announced the retrofit.

Highlights:

  • Each vessel is anticipated to see 25 percent fuel savings.
  • A revenue-sharing collaboration between charterers and owners is agreed upon for the savings.
  • Hammonia earns a five-year time charter.
  • One of the three vessels that is Liberian flagged is eligible for a 50 percent tonnage tax discount for the first year after retrofit.
  • CWR awarded Hammonia a $120,000 grant to retrofit the vessels.
  • The deal creates a win-win scenario for both charterers and owners.
  • The option of profit sharing does the best in a market of overcapacity.
  • The Dutch Postcode Lottery has granted €1 million ($1.09 million) to CWR and Rocky Mountain Institute (RMI) for their LeaderShip project, expanding their efforts in the Shipping industry, including collaboration with the Port of Rotterdam.

The technology:

The retrofit bundle installation includes:

  • Optimized bulbous bow
  • Rudder optimization
  • High-performance hull coating as well as trim and ballast optimization at standard drydock.

A continuous monitoring software is installed on the vessels in order to measure, verify and publicize the fuel and carbon savings.  The data will be analysed by the independent third-party University College London (UCL) over a five-year period, with initial results being released to the industry six months post-drydock.
