USCG: Sector Ohio Valley Issues MSIB 01-2020 Related to Non-Compliance with NTVRP Requirements

We’ve recently encountered issues with operators that have vessels that have been measured to both the “Regulatory” tonnage (GRT) and “Convention (International)” tonnage (ITC) that were surprised during COI inspections that the USCG was holding them to the ITC with regard to compliance with the Non-Tank Vessel Response Plan requirements.

Sector Ohio Valley has issued MSIB 01-2020 clarifying their position on the matter stating:

Vessels that actively operate in commercial operations without a NTVRP are subjected to, but not limited to, the following penalties; vessel detainment by the United States Coast Guard (USCG), denial of entry into a U.S. port, and/or civil penalties of more that $47,000 per day dependent upon type and scope of violation. The USCG encourages the maritime community to review the requirements and ensure their vessels meet the regulations outlined in 33 CFR Part 155 – Subpart J.

A point of confusion has arisen in terms of tonnage application for the 400 gross tons threshold. As discussed in the preamble of the regulation (Federal Register / Vol. 78, No. 189 / Monday, September 30, 2013 / Rules and Regulations), if a vessel is measured using “Convention (International)” tonnage and “Regulatory” tonnage, the greater of the two is used for determining applicability of the NTVRP requirements.

USCG: MSIB 04-19 Cyber Adversaries Targeting Commercial Vessels

Originally published on the Coast Guard Maritime Commons 05/28/2019

The Office of Commercial Vessel Compliance issued Marine Safety Information Bulletin 04-19, “Cyber Adversaries Targeting Commercial Vessels,” to inform the maritime industry of recent email phishing and malware intrusion attempts that targeted commercial vessels. 

Cyber adversaries are attempting to gain sensitive information including the content of an official Notice of Arrival (NOA) using email addresses that pose as an official Port State Control (PSC) authority such as: port @ Additionally, the Coast Guard has received reports of malicious software designed to disrupt shipboard computer systems. Vessel masters have diligently reported suspicious activity to the Coast Guard National Response Center (NRC) in accordance with Title 33 Code of Federal Regulations (CFR) §101.305 – Reporting, enabling the Coast Guard and other federal agencies to counter cyber threats across the global maritime network. 

As a reminder, suspicious activity and breaches of security must be reported to the NRC at (800) 424- 8802. For cyber attempts/attacks that do not impact the operating condition of the vessel or result in a pollution incident, owners or operators may alternatively report to the 24/7 National Cybersecurity and Communications Integration Center (NCCIC) at (888) 282-0870 in accordance with Policy Letter 08-16, “Reporting Suspicious Activity and Breaches of Security.” When reporting to the NCCIC, it is imperative that the reporting party notify the NCCIC that the vessel is a Coast Guard regulated entity in order to satisfy 33 CFR §101.305 reporting requirements. The NCCIC will in turn forward the report to the NRC, which will then notify the cognizant Coast Guard Captain of the Port. 

The Coast Guards urges maritime stakeholders to verify the validity of the email sender prior to responding to unsolicited email messages. If there is uncertainty regarding the legitimacy of the email request, vessel representatives should try contacting the PSC authority directly by using verified contact information. Additionally, vessel owners and operators should continue to evaluate their cyber defense measures to reduce the effect of a cyber-attack. 

For more information on the NCCIC’s services, cyberrelated information, best practices, and other resources, please visit: The Coast Guard applauds companies and their vessels for remaining vigilant in the identification and prompt reporting of suspicious cyber-related activities.
