Response: The Safety Board appreciates API's highlighting the various activities that have taken place since this recommendation was issued, including (1) the extensive revisions to American Society of Mechanical Engineers' (ASME's) code B31.4, which added a new chapter on offshore operations; (2) API's 1999 publication of Recommended Practice 1111, which addresses the design, construction, operation, and maintenance of offshore hydrocarbon pipelines; and (3) the 1994 National Academy of Sciences report on the safety of marine pipelines. We have also searched our records again and found that API had, in fact, responded to our recommendation on March 30, 1980, indicating that the Board's recommendation had been forwarded to two API committees that comprise member companies. In view of the above, Safety Recommendation P-80-15 is now classified "Closed--Acceptable Action."

To: NTSB
Date: 6/8/2001
Response: Letter Mail Controlled 06/08/2001 7:37:07 PM MC# 2010482 API no longer has any records of specific actions related to this safety recommendation from 1980. Many reviews of offshore operating systems and equipment have been undertaken over the last 20 years. Most of the codes, such as ASME B31.4 have been extensively revised, including the addition of a complete new chapter on offshore operations. In 1999, API published Recommended Practice 1111, Design, Construction, Operation, and Maintenance of Offshore Hydrocarbon Pipelines (Limit State Design). In that recommended practice both communications and signs to provide hazard warnings are covered. In 1994, the National Academy of Sciences convened a committee to evaluate the safety of marine pipelines. That committee's final report is entitled, "Improving the Safety of Marine Pipelines." This report is available to offshore production and pipeline operators. The portions of the report that are specific to pipeline avoidance techniques for vessels are attached to this letter.
