Coast Guard Marine Safety Alert 15-25: THE IMPORTANCE OF EFFECTIVE COMMUNICATION WHEN COMPLETING A DECLARATION OF INSPECTION

A recent oil spill on the Delaware River starkly underscored the critical need for effective communication when completing the required Declaration of Inspection (DOI) prior to an oil transfer in accordance with Title 33, Code of Federal Regulations (CFR), §156.120 (33 CFR 156.120). Prior to the incident, the facility person in charge (PIC) filled out their section of the DOI and sent the checklist in a bucket hoist to the barge PIC who subsequently completed their portion. Notably, the two PICs never met in person nor exchanged any words throughout the DOI preparation process. The investigation revealed that a significant causative factor to the cargo tank overfill and subsequent discharge of at least 100 barrels (4,200 gallons) of oil into the Delaware River was the lack of direct communication between the PICs.

The Captain of the Port (COTP), Delaware Bay, is notifying mariners of the amended anchorage regulations, specifically 33 CFR 110.157, paragraphs (a)(18)-(20) for the Delaware Bay and River, and adjacent waters, which established two offshore deep-water anchorages.
