The Panamanian Registry is the first naval registry globally to enforce mandatory traceability for hydrocarbon ship-to-ship operations on the high seas.
According to the new regulations, any oil tanker flying the Panamanian flag and having a gross tonnage of 150 tonnes or more is required to notify the Panama Maritime Authority (AMP) at least 48 hours before executing an STS manoeuvre.
Overview of the New Regulation
Oil tankers must supply the operation's logistical and technical details. Failure to comply with this regulation may result in the ship's Panamanian registration being cancelled.
Notably, the General Directorate of Merchant Navy's Resolution No. 106-035-DGMM describes this regulation, which went into force on August 6, 2025.
Identification, timing, exact position, operational mode requirements, hydrocarbon type and quantity information, expected duration, designated contact individuals, and verification of MARPOL Agreement compliance are among the
mandatory data that vessels must submit.
Moreover, the legislation deals with the growing number of ships being used for illicit activities, such as illicit crude oil transportation, sanctions evasion, environmental control violations, and the operation of the “ghost fleet” of tankers.
This action coincides with Panama's crackdown on the shadow fleet's operations.
Maritime Law Courses in the UK cover regulations such as MARPOL Annexe I, Regulation 41, which requires STS plans for oil tankers, and Panama's Resolution No. 106-035-DGMM, addressing vessel identification, location, and operation details, legal framework, approval processes, and compliance procedures.
Enhancing the Registration Process
As part of its zero-tolerance policy against abuse of its ship register, the Panama Maritime Authority recently started the process of cancelling the registration of 17 ships that had been sanctioned by the United States.
Besides, numerous organisations, including United Against Nuclear Iran, have condemned Panama, pointing out that 17% of ships suspected of transporting Iranian oil currently fly the Panamanian flag.
In response, the Panamanian Registry has taken several enforcement actions. The commission deregistered 107 ships linked to sanction violations in March 2025.
Furthermore, Panama has enhanced due diligence procedures for ship registrations and participation in the Registry Information Company with other flag states. It has implemented a new age restriction policy that forbids the registration of oil tankers or bulk carriers older than 15 years.
In short, through the promotion of maritime safety, operational transparency, and marine environment conservation, Panama claims that its actions are compliant with IMO regulations and reaffirms its commitment as a responsible flag-holding state.
