Formerly (CG-521), (CG-3PSE), and (G-MSE)
The Office of Design and Engineering Standards is responsible for developing and promulgating national regulations and standards that govern the safe design and construction of ships and shipboard equipment, including hull structure, stability, electrical & mechanical systems, lifesaving & fire safety equipment, and related equipment approval and laboratory acceptance. Additionally, it establishes policy, provides technical clarifications, and resolves any appeals. Furthermore, it represents the United States on several committees and sub-committees at the International Maritime Organization (IMO) and is actively engaged with various standards committees (e.g., ASTM, IEEE, NFPC, etc) as well as classification society rules committees (e.g., ABS, LR, DNV, etc.).
The office is divided into five technical divisions:
Spring 2015 Marine Safety Engineering Newsletter. The Commercial Regulations & Standards Directorate has published the latest edition of the Marine Safety Engineering Newsletter.
Design Standards for U.S. Barges Intending to Carry Liquefied Natural Gas in Bulk. The Coast Guard recently released CG-ENG Policy Letter 02-15 to provide interim guidance for the design standards for barges carrying liquefied natural gas in bulk.
Electrical Equipment in Hazardous Locations. On March 31, 2015, the Coast Guard published a final rule (80 FR 16980) applicable to mobile offshore drilling units, floating outer continental shelf (OCS) facilities, and vessels, other than offshore supply vessels regulated under 46 CFR Subchapter L, constructed after April 2, 2018 that engage in OCS activities. The regulations expand the list of acceptable national and international explosion protection standards and add the internationally accepted independent third-party certification system, the International Electrotechnical Commission System for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx), as an accepted method of testing and certifying electrical equipment intended for use in hazardous locations.
Requirements for Facilities Transferring Oil or Hazardous Materials in Bulk. The Coast Guard recently published corrections (80 FR 7539) to 33 CFR Part 154 regarding VCS for facilities.
Interim Guidance for Regulated Facilities for the Review and Approval of Mobile Vapor Control Systems. The Coast Guard recently released CG-ENG Policy Letter No. 01-15 to provide interim guidance to Coast Guard Captains of the Port (COTPs) to assist in the assessment of equivalency requests from regulated facilities to use mobile or portable vapor control systems (VCSs) in lieu of fixed VCSs.
Requirements for MODUs and Other Vessels Conducting Outer Continental Shelf (OCS) Activities with Dynamic Positioning (DP) Systems. On November 28, 2014, the Coast Guard published a notice of proposed rulemaking (79 FR 70944), establishing minimum design, operation, training, and manning standards for mobile offshore drilling units (MODUs) and other vessels using DP systems to engage in OCS activities. The deadline for comment submission on this proposed rule is February 26, 2015. A summary announcement of the rule can be found on the Coast Guard Maritime Commons. Additionally, we have provided initial general FAQs, and we will update as needed. The Coast Guard announced on February 6, 2015 (80 FR 6679) that it is extending the comment period deadline by 90 days to May 27, 2015.
Fire and Explosion Analyses - Outer Continental Shelf Units. On May 2, 2014, the Coast Guard published a Federal Register notice of recommended interim voluntary guidance (79 FR 25139) concerning fire and explosion analyses for MODUs and manned fixed and floating offshore facilities engaged in activities on the U.S. OCS. For more information please see the Federal Register notice above.
Shale Gas Extraction Waste Water Transport in Bulk. On October 30, 2013, the Coast Guard published a Federal Register notice of availability and request for comments (78 FR 64905) for a proposed policy letter concerning the carriage of shale gas extraction waste water in bulk via barge. The proposed policy letter specifies the conditions under which a barge owner may request and be granted a Certificate of Inspection endorsement or letter allowing the barge to transport shale gas extraction waste water in bulk. The policy letter also defines the information the Coast Guard may require the barge owner to provide and specifies the additional requirements the Coast Guard is considering imposing on such barges.
Liquid Chemical Categorization Updates. The Coast Guard published a Federal Register Notice of Interim Rule to update the tables that list liquid hazardous materials, liquefied gases, and compressed gases that are approved for transportation in bulk. The interim rule (78 FR 50148) initially published on August 16, 2013 and updated by 78 FR 56837 has been further updated by 79 FR 2106 to reflect a delayed effective date of January 16, 2015. The delay until 2015 will allow the Coast Guard to investigate and, if necessary, correct technical errors that were brought to the Coast Guard's attention by public comments on the interim rule. For more information please see the Federal Register notices above.
