BOW HERCULES is a 2017 tank ship. The Coast Guard has recorded 16 inspections since 2018, most recently in July 2025, along with 1 deficiency and 1 operational control.
Records from 2018 to 2025. Most recent: inspection, 16 July 2025.
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.
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. What Maury does
not do.

9900- Other (not clearly hazardous)- To discharge ballast into the waters of the U.S. after the dates listed in 33 CFR 151.2035(b), the vessel must use a USCG-approved BWTS, use only water from the public water system, or use an AMS.
Subject vessel is a "new vessel" [constructed after 01DEC2013; keel laid date 22DEC2015] and therefore compliance date is apon delivery.

PSCOs unable to verify that required UV intensity of 150 mJ/cm2 [per AMS letter dated 22MAR2017] can be provided with inoperable bulb.

Ownership record

Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
