Restricted Maneuverability of Vessels during Cargo Operations

What is the classification of a vessel transferring cargo while underway according to USCG 207 rules?

A. not under command

B. constrained by her draft

C. in special circumstances

D. restricted in her ability to maneuver

Answer:

The correct classification of a vessel transferring cargo while underway according to USCG 207 rules is as a vessel "restricted in her ability to maneuver".

In the context of USCG 207, both internationally and inland, a vessel that transfers cargo while underway is classified by the rules as a vessel restricted in its ability to maneuver. This classification refers to vessels that, due to the nature of their work (like transferring cargo), are restricted in their capacity to alter their course or speed. These vessels operate under certain rules and regulations to ensure safe navigation as they pose risks to other vessels due to their restricted maneuverability.

For example, container ships have two operational behaviors that separate them from other ship types. They have the ability to transfer ballast water internally among tanks to maintain stability during cargo operations and to entrain ballast water from open ocean sources, reducing the need for ballast water exchange. These navigation and operational conditions are governed according to federal frameworks, such as regulations set by the US Coast Guard and the US Environmental Protection Agency.

Regulations include the submission of a Ballast Water Report which provides details about the ballast water history, such as discharge locations, and ballast water management details.
