KIRBY 32008B

If during an internal structural examination, cargo tank internal examination, or underwater survey, damage or deterioration to the hull plating, structural members, or cargo tanks is discovered, the Officer in Charge, Marine Inspection, may require the vessel to be drydocked or otherwise taken out of service to further assess the extent of the damage and to effect permanent repairs. During the COI exam, scattered deep pitting was observed on the cargo tank top. For the duration leading up to the next required internal structure exam, the vessel must conduct annual gauging of the deeply pitted areas to ensure that no further degradation of the existing plate occurs that may require repair. The results of this gauging must be provided to the company TBSIP USCG coordinator. If any deep pit exceeds allowable limits for structural wastage, a repair plan must be submitted to the USCG for further evaluation.

No extensive repairs to the hull or machinery which affect the safety of a vessel shall be made without the knowledge of the Officer in Charge, Marine Inspection. The burden for proposing acceptable repairs rests upon the vessel owner. Owner failed to notify the USCG of the clad welding pit repairs that occurred on the forward tank top trunk facing the bow.

If, during an internal structural examination, cargo tank internal examination, or underwater survey, damage or deterioration to the hull plating, structural members, or cargo tanks is discovered, the Officer in Charge, Marine Inspection, may require the vessel to be drydocked or otherwise taken out of service to further assess the extent of the damage and to effect permanent repairs. During the COI exam, heavily pitted areas were observed on the forward area of the cargo tank top which were coated at the time of inspection. MIs requested a previous gauging report that was done prior to MI attendance on 12Oct25. Gauging report listed numerous heavily pitted areas of the tank top vertical plate facing the bow in excess of 50% wastage with less than 1/4" material remaining. Operator stated that clad welding was used to mitigate the affected areas which was not brought to the attention of the attending MI during the drydock, internal structural exam, and cargo tank internal exams. Operator must provide a scope of repairs for the areas that were clad welded to further evaluate total scope of work and adequacy of repair.

Prior to cargo discharge operations, emergency shut-down for cargo pump prime mover must be tested to satisfaction of attending Marine Inspector.

The High level alarms were inoperable.

Make modification to cargo pump engine control panel to ensure compliance with 46 CFR 111.105-5 and 111.105-31(1).
