{"abstract":"On May 4, 2012 the Coast Guard published a notice of recommended interim voluntary guidance titled \"Mobile Offshore Drilling Unit Dynamic Positioning Guidance\". The notice recommended owners and operators of Mobile Offshore Drilling Units (MODUs) follow Marine Technology Society (MTS) Dynamic Positioning (DP) operations guidance for MODUs. The Coast Guard is now also recommending owners and operators of all vessels other than MODUs conducting Outer Continental Shelf (OCS) activities on the U.S. OCS follow the appropriate MTS DP operations guidance for these vessels. In particular, the Coast Guard recommends owners and operators of these vessels operate within an Activity Specific Operating Guideline for each activity and operate with its Critical Activity Mode of Operation when that activity is critical.","action":"Notice of Recommended Interim Voluntary Guidance.","agencies":[{"raw_name":"DEPARTMENT OF HOMELAND SECURITY","name":"Homeland Security Department","id":227,"url":"https://www.federalregister.gov/agencies/homeland-security-department","json_url":"https://www.federalregister.gov/api/v1/agencies/227","parent_id":null,"slug":"homeland-security-department"},{"raw_name":"Coast Guard","name":"Coast Guard","id":53,"url":"https://www.federalregister.gov/agencies/coast-guard","json_url":"https://www.federalregister.gov/api/v1/agencies/53","parent_id":227,"slug":"coast-guard"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2012/10/12/2012-25132.html","cfr_references":[],"citation":"77 FR 62247","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The policy outlined in this document is effective October 12, 2012.","disposition_notes":null,"docket_ids":["Docket No. USCG-2011-1106"],"dockets":[],"document_number":"2012-25132","effective_on":"2012-10-12","end_page":62248,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/10/12/2012-25132.xml","html_url":"https://www.federalregister.gov/documents/2012/10/12/2012-25132/dynamic-positioning-operations-guidance-for-vessels-other-than-mobile-offshore-drilling-units","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-25132?publication_date=2012-10-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-10-12/2012-25132/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":590,"last_updated":"2026-10-25 08:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-10-12/pdf/2012-25132.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-25132.pdf?1349986681","publication_date":"2012-10-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/10/12/2012-25132.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Supplemental Material: Marine Technology Society DP Committee","document_id":"USCG-2011-1106-0020"},{"title":"Supplemental Material: Darley Contracting Inc.","document_id":"USCG-2011-1106-0019"},{"title":"February 9, 2012 Public Meeting Transcript","document_id":"USCG-2011-1106-0018"},{"title":"DP EDS Policy Letter Enclosure 1","document_id":"USCG-2011-1106-0003"},{"title":"DP EDS Policy Letter","document_id":"USCG-2011-1106-0002"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=USCG-2011-1106","supporting_documents_count":5,"docket_id":"USCG-2011-1106","regulation_id_number":null,"title":"MODU Notice of Availability and Request for Comments","checked_regulationsdotgov_at":"2012-11-18T05:01:50Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":62247,"subtype":null,"title":"Dynamic Positioning Operations Guidance for Vessels Other Than Mobile Offshore Drilling Units Operating on the U.S. Outer Continental Shelf","toc_doc":"Vessels other than Mobile Offshore Drilling Units Operating on the U.S. Outer Continental Shelf","toc_subject":"Dynamic Positioning Operations Guidance:","topics":[],"type":"Notice","volume":77}
