NAVIGATOR LIBRA is a 2012 tank ship. The Coast Guard has recorded 7 inspections since 2021, most recently in March 2026, along with 5 deficiencies and 1 operational control.
Records from 2021 to 2026. Most recent: inspection, 25 March 2026.
Coast Guard record current through 23 August 2026, retrieved 5 September 2026 from PSIX. Every field on this page was recorded by the Coast Guard. Records for the Tank Ship class in Maury's sources begin in 2016.
Every line above is a count of records the US Coast Guard wrote, or a date it recorded.
The counts in the strip above are the same counts; this table splits the inspections by
the kind of activity recorded. A blank resolution means none was recorded in this data; it
does not establish that a deficiency is outstanding. Years with a record are calendar
years in which a record exists, not years in service.

This hull's Official Number is not in the NVDC file dated 10 August 2026 as served by NOAA Fisheries, so no documentation record is shown. Absence from that file is a fact about the file, not about the hull.

What it gives that this page does not: the whole record in one
dated, citable document — every line with its Coast Guard activity id, the retrieval
date on the cover, built to print to PDF with its page breaks — that a surveyor can
attach and a lender can file. The same facts as this page, complete and in one file.
Every recorded inspection, 2016 to
2026 for this class, in one chronology · every deficiency, with system, dates
and resolution · operational controls imposed and removed · every name this
hull has been recorded under · the vessels it was inspected alongside, and when
· how its record compares with hulls of similar age and size, as a fact about the
population and never a judgement about this vessel.
A request, not a checkout: leave an email and Maury replies once, with
the dated document for this hull and a Stripe invoice for $299. Nothing is charged before
the document is in your hands.

Issued 31 March 2024Resolved
Gas detection equipment should ne so designed that it may be readily tested, testing and calibration should be carried out at regular intervals. PSCO observed attempts by the ships crew to test the fixed gas detection system by applying a 50% LEL propane span gas to a sample point in the cargo compressor room, which resulted in a reading of 170% LEL, via the VCM LEL sensor with the gas detection system.

Issued 31 March 2024Resolved
Spaces surrounding refrigerated cargo tanks not having secondary barriers should be filled with suitable dry inert gas or dry air and be maintained in this condition with make up inert gas provided by a shipboard inert gas generation system, shipboard storage of inert gas, or dry air provided by suitable air drying system. The vessels fixed and portable gas detectors show 7% LEL in the hold space around the number 3 port and starboard cargo tanks .

06 - Cargo Operations Including Equipment › N/A - No Subsystem › Cargo operation
Issued 31 March 2024Resolved
Provisions should be made by the use of offsets, loops, bends, mechanical expansion joints or similar suitable means to protect the piping, piping system components, and cargo tanks from excessive stresses due to thermal movement and from movements of the tank and hull structure. Where mechanical expansion joints are used in piping, they should be held to a minimum and, where located outside cargo tanks, should be of the bellow type.
While conducting deck examination, PSCO identified missing securing nuts on nu 1 starboard expansion joint limiters.

Issued 31 March 2024Resolved
The condition of the ship and its equipment should be maintained to conform with the provisions of the code to ensure that the ship will remain fit to proceed to sea without danger to the ship or persons on board.
PSCO identified active leak in sea water piping system for the condenser within the cargo compressor room. Sea water is actively leaking from and approximately 1/8" hole in piping that was concealed with electricity tape.

Issued 31 March 2024Resolved
Every company should develop, implement, and maintain a safety management system which includes the following functional requirements: Instructions and procedures to ensure safe operation of ships and protection of the environment in compliance with relevant international and flag state legislation. As outlines in deficiency number 1, the company has not provided the crew with procedures for calibrating and adjusting the fixed gas detection system for changes in cargoes. The company's procedure for annually inspecting the fixed gas detection system and properly calibrating it to the associated span gas stated that the reading of 12MA is satisfactory, but this reflected a reading of 170% LEL with a 50% LEL span gas being applied. An internal audit should be conducted.

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.
