Safety Recommendation M-81-021
Details
Synopsis: ON MAY 9, 1980, THE LIBERIAN BULK CARRIER M/V SUMMIT VENTURE RAMMED A SUPPORT PIER OF THE WESTERN SPAN OF THE SUNSHINE SKYWAY BRIDGE IN TAMPA BAY, FLORIDA. AS A RESULT OF THE RAMMING, THE SUPPORT PIER WAS DESTROYED AND ABOUT 1,297 FEET OF BRIDGE DECK AND SUPERSTRUCTURE FELL ABOUT 150 FEET INTO THE BAY. A GREYHOUND BUS, A SMALL PICKUP TRUCK, AND SIX AUTOMOBILES FELL INTO THE BAY AND 35 PERSONS DIED. REPAIR COSTS WERE ESTIMATED AT ABOUT $30 MILLION FOR THE BRIDGE AND ABOUT $1 MILLION FOR THE SUMMIT VENTURE.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL HIGHWAY ADMINISTRATION: IN COOPERATION WITH THE U.S. COAST GUARD, CONDUCT A STUDY TO DETERMINE WHICH EXISTING BRIDGES OVER THE NAVIGABLE WATERWAYS OF UNITED STATES PORTS AND HARBORS ARE NOT EQUIPPED WITH ADEQUATE STRUCTURAL PIER PROTECTION.

Response: THE STATE OF LOUISIANA HAS DEVELOPED A MANUAL TITLED "CRITERIA FOR: THE DESIGN OF BRIDGE PIERS WITH RESPECT TO VESSEL COLLISION IN LOUISIANA WATERWAYS." ALTHOUGH SPECIFICALLY PREPARED FOR LOUISIANA, THE MANUAL PROVIDES IN DEPTH PROCEDURES FOR ANALYZING AND DESIGNING BRIDGES TO MINIMIZE VESSEL COLLISIONS. THIS MANUAL HAS BEEN DISTRIBUTED TO ALL STATES THROUGH THE AASHTO HIGHWAY SUBCOMMITTEE ON BRIDGES AND STRUCTURES AND WAS DISCUSSED AT THE NATIONAL MEETINGS HELD IN 1985. THE CRITERIA WAS REFERRED BACK TO A SUBCOMMITTEE FOR FURTHER REVIEW AND DEVELOPMENT FOR CONSIDERATION AND LATER ADOPTION AS NATIONAL STANDARDS.

Response: FHWA LTR: OUR MARCH 5 RESPONSE TO M-81-21 AND -22 NOTED THAT THE FHWA WOULD ISSUE A MEMORANDUM TO FIELD OFFICES INSTRUCTING THEM TO BE SURE THAT STATE INSPECTIONS OF BRIDGES OVER NAVIGABLE WATERS CONTINUE TO INCLUDE AN ASSESSMENT AND EVALUATION OF BRIDGE PIERS AND FENDERING SYSTEMS FOR STRUCTURAL INTEGRITY. ON OCTOBER 30 THE FHWA SENT SUCH A MEMORANDUM TO OUR FIELD OFFICES. A COPY IS ENCLOSED. WE BELIEVE THE ISSUANCE OF THIS MEMORANDUM COMPLETES THE FHWA'S ACTION ON M-81-21 AND -22. WITH OUR PREVIOUS RESPONSES TO M-81-20, WE RESPECTFULLY REQUEST THAT M-81-20, 21 AND 22 BE CLASSIFIED AS CLOSED.

Response: FHWA LETTER: AS NOTED IN SAFETY RECOMMENDATION M-81-20, THERE IS NO UNIVERSAL STANDARD WHICH CAN BE DEVELOPED TO DETERMINE WHETHER A GIVEN PIER PROTECTION SYSTEM IS OR IS NOT ADEQUATE. SUCH EVALUATIONS MUST BE MADE ON A CASE-BY CASE BASIS THROUGH THE APPLICATION OF ENGINEERING JUDGEMENT (1) IN ASSESSING THE RISKS AND CONSEQUENCES OF POTENTIAL SHIP-BRIDGE COLLISION IMPACTS AND (2) IN DETERMINING WHETHER ADDITIONAL PROTECTION IS COST-EFFECTIVE IN IMPROVING THE EXISTING CONDITIONS. FHWA DOES NOT HAVE THE RESOURCES TO CONDUCT THE REQUESTED STUDY; HOWEVER, ALL HIGHWAY BRIDGES ARE NOW BEING INSPECTED ON A REGULAR BASIS BY THE RESPECTIVE HIGHWAY AGENCIES. THE INSPECTION OF BRIDGE PIERS AND FENDERING SYSTEMS IS A PART OF THIS OVERALL NATIONAL BRIDGE INSPECTION PROGRAM. THE FHWA WILL ISSUE A MEMORANDUM TO FIELD OFFICES INSTRUCTING THEM TO BE SURE THAT STATE INSPECTIONS OF BRIDGES OVER NAVIGABLE WATERS CONTINUE TO INCLUDE AN ASSESSMENT AND EVALUATION OF BRIDGE PIERS AND FENDERING SYSTEMS FOR STRUCTURAL INTEGRITY AS PROVIDED FOR IN THE BRIDGE INSPECTOR'S TRAINING MANUAL - 70, SECTION 5-25. AS ADDITIONAL TECHNICAL INFORMATION BECOMES AVAILABLE CONCERNING THE EVALUATION OF PIER PROTECTION SYSTEMS ON EXISTING BRIDGES, THE FHWA WILL TAKE APPROPRIATE MEASURES TO BE SURE THAT IT IS INCLUDED, TO THE EXTENT PRACTICAL, IN THE ONGOING NATIONAL BRIDGE INSPECTION PROGRAM.

Response: FHWA LTR: U.S. COAST GUARD OFFICIALS HAVE INFORMED FHWA THAT THE STUDY RECOMMENDED IS BEYOND THEIR SCOPE AND AUTHOR ITY. THE FHWA COULD, THROUGH REGULATORY REVISIONS UNDER THE PROVISIONS OF THE NATIONAL BRIDGE INSPECTION STANDARDS, INITIATE AND ADMINISTER SUCH A STUDY; HOWEVER, THE DATA GATHERING AND ANALYSIS PHASES WOULD TAKE AS LONG AS FIVE YEARS AFTER THE REQUIRED REGULATIONS WERE IMPLEMENTED. THIS IS NOT DESIRABLE. FHWA HAS RECENTLY BEEN INFORMED THAT THE MARINE BOARD, NATIONAL RESEARCH COUNCIL, ASSEMBLY OF ENGINEERING, WASHINGTON, D.C., HAS PREPARED A PROSPECTUS FOR THE NEEDED STUDY. THEIR PROSPECTUS IS ENTITLED, "SHIP COLLI SIONS WITH BRIDGES," AND THE RESULTANT STUDY WILL FULFILL RECOMMENDATION M-81-21 WHEN COMPLETED. BECAUSE FORMAL REQUESTS FOR PROPOSALS HAVE NOT YET BEEN SENT OUT BY THE MARINE BOARD, THE PROSPECTUS IS CONSIDERED PRIVILEGED INFORMATION; THEREFORE, WE ARE UNABLE TO PROVIDE A COPY OF THIS PROSPECTUS. THE FHWA HAS REVIEWED THE PROSPECTUS AND HAS WRITTEN TO THE MARINE BOARD, ENDORSING THE STUDY AND PLEDGING OUR COOPERATION AND ASSISTANCE.
