U.S. Coast Guard Implements Temporary Safety Zone in Honolulu for Ship-to-Shore Crane Transportation

On October 21, 2026, the United States Coast Guard formally established a temporary safety zone in the navigable waters of Mamala Bay, Honolulu, Hawaii. This regulatory action is in response to the planned arrival and movement of the tug T/V DENISE FOSS and its tow, FOSS 3612, which are transporting two substantial ship-to-shore cranes. The safety zone, a 500-yard radius around these vessels, is intended to protect personnel, other marine traffic, and the marine environment from potential hazards associated with the large and potentially restricted maneuverability of the tow. The zone's enforcement began on October 19, 2026, and will remain in effect through 8 a.m. on October 24, 2026, or until the vessels safely enter the Honolulu Harbor Security Zone.

Background to the Temporary Measure

The need for this temporary safety zone arose following a notification received by the Coast Guard on October 13, 2026. Pasha Hawaii, a shipping company, is responsible for transporting the two ship-to-shore cranes from Los Angeles, California, to Honolulu. The method of transport involves a tug and barge, a configuration that inherently limits the maneuverability of the maritime convoy. The Captain of the Port (COTP) Honolulu, assessing the potential risks, determined that the presence of these large cranes in transit within Mamala Bay poses a significant safety concern for any individuals or vessels in the immediate vicinity. This determination led to the activation of authorities under 46 U.S.C. 70034, which empowers the Coast Guard to establish such protective zones.

Regulatory Authority and Expedited Action

The rule creating this safety zone is categorized as a temporary final rule. A notable aspect of its promulgation is the Coast Guard's decision to issue it without prior public notice and comment, as well as making it effective less than 30 days after publication in the Federal Register. Federal administrative law generally requires agencies to provide public notice of proposed rules and an opportunity for comment before a rule becomes final. However, exceptions exist under the Administrative Procedure Act, specifically 5 U.S.C. 553(b)(B) and 5 U.S.C. 553(d)(3).

The Coast Guard justified these waivers by citing good cause due to the immediate need for the safety zone. The agency received notification of the event on October 13, 2026, but the safety zone needed to be in place by October 19, 2026, to ensure public safety and environmental protection. This short timeframe made it impracticable to solicit and respond to public comments before the anticipated arrival of the tow. Similarly, the urgency precluded adherence to the standard 30-day waiting period for a rule's effectiveness, making it necessary to implement the rule swiftly.

Scope and Enforcement of the Safety Zone

The established safety zone encompasses all navigable waters within a 500-yard radius around the T/V DENISE FOSS, bearing official number 1254223, and its tow, FOSS 3612, official number 1255436. During the specified enforcement period, entry by any vessel or person into this zone is strictly prohibited unless explicit authorization is obtained from the Captain of the Port, Sector Honolulu, or their designated representative. Designated representatives include Coast Guard personnel such as Patrol Commanders, coxswains, petty officers, and other officers operating Coast Guard vessels, as well as Federal, State, and local officers assisting the COTP in enforcement duties. Mariners requiring permission to enter the zone are directed to contact the COTP or their representative via VHF-FM channel 16 or by telephone at 800-552-6458. Compliance with all lawful orders from the COTP or their representatives is mandatory for those within the safety zone.

Broader Implications and Regulatory Oversight

Beyond the immediate safety concerns, the establishment of this temporary safety zone highlights the ongoing challenges of managing maritime traffic and ensuring safety in dynamic port environments. The Coast Guard's ability to act quickly through temporary final rules underscores the necessity of regulatory flexibility in addressing unforeseen or rapidly developing situations. While the waiver of public notice and comment is a significant departure from standard procedure, it is balanced against the imperative to prevent accidents involving large, hazardous maritime transports. The Coast Guard's regulatory analysis confirmed that the rule would not significantly impact small entities, necessitate new information collection, raise federalism or tribal implications, or result in unfunded mandates. Furthermore, the agency determined the action is categorically excluded from further environmental review under the National Environmental Policy Act.

This incident also serves as a reminder of the critical role played by the Captain of the Port in safeguarding waterways, balancing the needs of commerce with the paramount concerns of safety and environmental protection. The detailed parameters of the safety zone and the clear enforcement mechanisms are designed to mitigate risks effectively during the critical phase of crane delivery to Honolulu.
