From a news release published in Seapower Magazine:

The Maritime Administration (MARAD) has announced an organizational realignment that will strengthen the agency’s ability to ensure the nation has sufficient capability to meet sealift needs during conflicts or national emergencies, according to a May 16 release from the Department of Transportation (DOT), which oversees MARAD.

The former Office of National Security is now the Office of Strategic Sealift, with three areas of focus; Federal Sealift, Commercial Sealift and Maritime Workforce. Federal Sealift continues to be responsible for Ready Reserve Force vessels, Emergency Preparedness and the National Defense Reserve Fleet. Commercial Sealift will coordinate both the Cargo Preference and Maritime Security Programs. The Office of Maritime Workforce Development will evaluate mariner training needs, and enforce service obligations for maritime academy graduates.
