28 Miss. Code. R. 301-29.7
Temporary berthing may be assigned tugs, barges, crew boats, research vessels or any other vessel during emergency, inclement weather, or any other condition requiring such assignment. Immediately upon arrival the master, owner, or agent must file a formal application for berth assignment. All such vessels are subject to all applicable port rules, regulations and charges. Should such vessels not have a licensed agent, the Port Authority may, at its discretion, act as the vessel's temporary agent and assign an agent's fee in the amount of $50 for each 30-day period of continued service for each unit (tow). All applicable charges shall be paid in full prior to departure of the vessel unless acceptable credit or bond is provided to the satisfaction of the Port Authority.
