Details
Synopsis: ON JUNE 29, 1989, THE U.S. SELF-ELEVATING UNINSPECTED LIFT BOAT M/V TITAN FINISHED ITS WORK AT CORPUS CHRISITI OIL AND GAS BLOCK 427 WHERE IT HAD BEEN ELEVATED IN ABOUT 95 FEET OF WATER. THE TITAN HAD A CREW OF FOUR, PLUS FIVE LAREDO CONSTRUCTION, INC., EMPLOYEES ABOARD. ABOUT 1330 THE MASTER LOWERED THE LIFTBOAT AND HEADED IT TOWARD FREPORT, TEXAS. WHILE THE 160-FOOT LEGS WERE BEING RAISED, THE TITAN BEGAN LISTING TO STARBOARD. THE MASTER BELIEVED THE LIST WAS CAUSED BY MUD ON THE STARBOARD LEG PAD. HOWEVER, THE MASTER FOUND ON INSPECTION THAT THE STARBOARD LEG WAS FLOODED AND GUSHING WATER ON DECK THROUGH A FRACTURE OR FRACTURES IN THE LEG. THE MASTER DIRECTED THE LEGS TO BE LOWERED TO IMPROVE THE STABILITY OF THE VESSEL. WHILE THE LEGS WERE BEING LOWERED THE TITAN CAPSIZED ABOUT 1345.
Recommendation: THE NTSB RECOMMENDS THAT THE U.S. COAST GUARD: REQUIRE THAT LIFTBOAT OPERATING MANUALS CONTAIN INSTRUCTIONS TO LIFTBOAT MASTERS TO INSPECT WATERTIGHT LEGS FOR FLOODING BEFORE JACKING DOWN, PRECAUTIONARY INFORMATION ABOUT THE DETRIMENTAL EFFECTS ON VESSEL STABILITY BECAUSE OF FLOODED LEGS, AND WHAT TO DO IF LEG FLOODING IS KNOWN OR SUSPECTED TO HAVE OCCURRED.

Safety Recommendation History
From: NTSB
To: USCG
Date: 11/6/1996
Response: M-90-86 ASKED THAT THE USCG REQUIRE THAT LIFTBOAT OPERATING MANUALS CONTAIN INSTRUCTIONS TO LIFTBOAT MASTERS TO INSPECT WATERTIGHT LEGS FOR FLOODING BEFORE JACKING DOWN, PRECAUTIONARY INFO ABOUT THE DETERIMENTAL EFFECTS ON VESSEL STABILITY BECAUSE OF FLOODED LEGS, & WHAT TO DO IF LEG FLOODING IS KNOWN OR SUSPECTED TO HAVE OCCURRED. BECAUSE CFR 134,170(B)(9) REQUIRES THAT SUCH GUIDANCE BE INCLUDED IN THE OPERATIONS MANUAL, M-90-86 HAS BEEN CLASSIFIED "CLOSED--ACCEPTABLE ACTION."

From: USCG
To: NTSB
Date: 3/15/1996
Response: THE USCG'S INTERIM FINAL RULES FOR OFFSHORE SUPPLY VESSELS/LIFTBOATS (46 CFR 90, ET AL.) (CGD82-004 & CGD86-074 PUBLISHED IN FR THURSDAY 11/16/95) BECAME EFFECTIVE THIS DATE.

From: NTSB
To: USCG
Date: 11/28/1994
Response: BECAUSE THE USCG INTENDS TO INCLUDE THIS RECOMMENDATION IN THE PENDING 46 CFR SUBCHAPTER L & REVISED NVIC 8-81, M-90-86 HAS BEEN CLASSIFIED "OPEN--ACCEPTABLE RESPONSE," PENDING PUBLICATION OF THE FINAL RULES.

From: USCG
To: NTSB
Date: 3/23/1994
Response: THE USCG ANTICIPATES THE RELEASE OF A REVISION TO NAVIGATION & VESSEL INSPECTION CIRCULAR 8-91 IN EARLY 1994, WHICH PERTAINS TO THE ISSUES RAISED IN THESE RECOMMENDATIONS. IN ADDITION, THE FINAL RULE OR SUBCHAPTER L, [CGD 82-004 & CGD 86-074] WHICH WILL ALSO ADDRESS THESE ISSUES, IS ANTICIPATED TO BE PUBLISHED BY MID 1994.

From: NTSB
To: USCG
Date: 5/18/1992
Response: Safety Recommendation M-90-86 urged the Coast Guard to require that liftboat operating manuals contain instructions to liftboat masters to inspect watertight legs for flooding before jacking down, precautionary information about the detrimental effects of flooded legs on vessel stability, and what to do if leg flooding is known or suspected to have occurred. The Safety Board notes that NVIC 8-91 recommends that the operating manuals for existing liftboats contain instructions to liftboat operators to inspect buoyant legs for flooding before jacking down and additional instructions on what to do if flooding is found. We further note that the Coast Guard intends to address this issue in the final rule for 46 Code of Federal Regulations (CFR) Subchapter L, Offshore Supply Vessels Including Liftboats (CGD 82-004 and CGD 86-074), which will apply to offshore supply vessels contracted for after the final regulations are published and in effect. Therefore, the Safety Board will hold Sjafety Recommendation M-91-86 in an "Open--Acceptable Response" status pending publication of the final rule.

From: USCG
To: NTSB
Date: 7/8/1991
Response: I CONCUR. AS INDICATED IN MY RESPONSE TO RECOMMENDATION M-90-085, NVIC 8-91 WILL PROVIDE GUIDANCE FOR OPERATING MANUALS OF EXISTING LIFTBOATS AND REQUIRES THAT THEY CONTAIN INSTRUCTIONS TO LIFTBOAT OPERATORS TO INSPECT BUOYANT LEGS FOR FLOODING BEFORE JACKING DOWN AND ADDITIONAL INSTRUCTIONS ON WHAT TO DO IF FLOODING IS FOUND. THE CG ALSO INTENDS TO ADDRESS THIS ISSUE IN THE FINAL RULE FOR 46 CFR SUBCHAPTER L, OFFSHORE SUPPLY VESSELS (CGD 82-004 AND CGD 86-074).
