Issued 2 May 2024
Resolved
IAW 46CFR140.900, “Each towing vessel must comply with the requirements of part 4 of this chapter for reporting marine casualties and retaining voyage records.” Vessel was discovered on dry-dock making repairs where a hole was in the hull, due to a grounding incident. No notification was made to the Coast Guard or the TPO. The master did state he made notification to the Company, as per their ISM. The company shall conduct an ISM/DOC external management audit, in the presence of a Coast Guard Third Party Oversight Coordinator.
02 - Structural Conditions › N/A - No Subsystem › Hull damage impairing seaworthiness
Issued 24 April 2024
Resolved
A towing vessel must be maintained and operated so the watertight integrity and stability of the vessel are not compromised. MI observed doubler patch being installed over a hole on the bottom plate of the vessel which was caused by running aground. The Coast Guard or Third Party Organization were not notified and the repair was not authorized by the Coast Guard or TPO.
The vessel representative must notify the TPO and objective evidence must be submitted to our office that authorized repairs were completed to the satisfaction of the TPO.

Issued 24 May 2021

All owners and operators of an existing towing vessel must have a valid COI prior to the specified phase-in period. This vessel is one of the associated fleet that has not obtained a valid COI.

If an inspection is not completed prior to this date, the action for this deficiency shall be changed to a 60 (Rectify deficiencies prior to movement) and the vessel may no long be permitted to operate.

Each line is an incident investigation the Coast Guard recorded with this hull among the vessels involved, with the date and the classification the Coast Guard gave it, and the bridge, lock or dam the investigation names where it names one. Involvement is not fault. The investigation narrative is not published. Source: IIR, through 2026.
Ownership record
The Coast Guard's documentation record for this hull -- the Abstract of Title,
with its owners and liens as filed -- is not in PSIX. Ask, and Maury buys it from the National
Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
