Which acronym refers to a plan designed for security when in port?

The acronym that refers to a plan designed for security when in port is ISP, which stands for "Intensive Security Plan." This plan typically outlines the necessary security procedures and protocols to be adopted by vessels while they are docked in port. It focuses on mitigating risks associated with the presence of the vessel in a potentially vulnerable environment, ensuring the crew, the ship, and cargo remain safe from various threat levels.

An Intensive Security Plan will generally include measures for access control, crew training on security best practices, and procedures for responding to security breaches. It is crucial for vessels to have such a plan in place as part of their overall safety and security management, especially considering the diverse and unpredictable risks they may encounter in a port setting.

The other acronyms represent different concepts related to maritime operations. MCF may refer to a specific framework or guidelines in context but does not directly relate to port security. LOGREQ stands for "Logging Requirement," typically associated with communication and logistical needs rather than security planning. MTF could denote "Marine Task Force," which also does not specifically pertain to a security plan in port but rather refers to a group organized for a particular maritime mission.
