The Annex to the Methodology for Retrofit Energy Efficiency Measures in Shipping provides an alternative method to monitor and calculate baseline and project fuel consumption, and fuel consumption savings, by using regression models based on ship hydrodynamics, the physics and resistance of a ship traveling through the water. The SGDL model, as it is called, is based on a code/software that has been developed by the Sea Grant Design Laboratory (SGDL) at the Massachusetts Institute of Technology (MIT) and relies on a model of ship fuel consumption as a function of a ship’s physical characteristics together with its speed and loading condition (draft). The model is less time-consuming and equally accurate (compared to “basic model” prescribed in the main text) as the estimates of fuel consumption and emission reductions are derived directly from a verified model of the ship’s fuel consumption. 
The code/software has been made publicly available at no cost via the MIT Sea Grant website.
