A letter of support consists of a written document that expresses the support of one or more port agencies or other agents and companies of the port-logistic community that endorse the port community’s interest in the implementation of the project. Likewise, it is advisable that the letters of support reflect the level of support offered by the agents, specifying what it will consist of (specifying characteristics and intensity).

These letters do not replace the agreement with the facilitator, which is of greater importance, as it contains the explicit commitment of the facilitating agent to allow the activities to be carried out under the terms set forth in the technical report for the implementation of the project.
