MARAD Report: Energy Efficiency & Battery Compartment Design


MARAD released an Energy Efficiency White Paper. The Maritime Administration (MARAD) has announced the availability of the Energy Efficiency White Paper that provides marine vessel owners and operators information on how to evaluate potential investments in efficiency measures and technologies. The white paper outlines the latest energy efficiency measures currently available for marine vessels, including how the technology works, potential fuel savings, applicability to various vessels types, and lifecycle costs.  If implemented, these types of energy efficiency measures may also assist owners of vessels undergoing a major conversion to comply with the Energy Efficiency for Ships Regulations contained in Chapter 4 of MARPOL Annex VI. The white paper was developed through the Ship Operations Cooperative Program (SOCP) with funding from MARAD’s Maritime Environmental and Technical Assistance Program.  The white paper can be found at  Contact: Kim Strong, 202.366.5807   MARAD Releases Report on Improved Battery Compartment Design for Hybrid Tugs The Maritime Administration (MARAD) has announced the availability of a report evaluating the design and construction of new battery components, as well as the risks and benefits of battery use in the power plant of a hybrid tugboat.
