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:
for Offshore Supply Vessels (OSVs).
The Office of Design and Engineering Standards has delegated
responsibility to the Marine Safety Center (CG-MSC) for
reviewing and approving design basis requests for certain
OSVs. From now on, OSVs
The Office of Design and Engineering Standards has delegated responsibility to the Marine Safety Center (CG-MSC) for reviewing and approving design basis requests for certain OSVs. From now on, OSVsless than 6,000 GT ITC (500 GRT) carrying more than 36 offshore workers, and OSVs of at least 6,000 GT ITC (500 GRT) with keels laid or contracted before August 18, 2014 may submit design basis letters to CG-MSC for approval. This transfer of authority will significantly increase the efficiency with which the Coast Guard reviews design basis requests and will ultimately improve the design review process for the maritime industry. For more information, please view the Interim Rule published in the Federal Register (79 FR 48894).
of Sewage Treatment Plants for Type Approval to
International Maritime Organization Resolution MEPC.227(64) . For
more information, please view the Federal Register notice (80
.The Coast Guard announces its acceptance of sewage treatment plants, also referred to as marine sanitation devices, for type-approval to International Maritime Organization resolution MEPC.227(64) as meeting the requirements for marine sanitation devices. This action will allow manufacturers, as well as shipowners and operators, the option to take advantage of building and using equipment that meets both domestic and international requirements while also benefitting the environment. The Coast Guard is also seeking information on simple onboard checks to verify performance of sewage treatment plants. Comments must be received on or before November 16, 2015.
For more information, please view the Federal Register notice (80 FR 62552).
Sewage Treatment Technology – Type Approval of Marine
Sanitation Devices Public Workshop . For more
information on how to attend, please view the Federal
Register notice (80
.The Coast Guard will hold a public workshop, December 8-9, 2015, in Washington, DC to discuss sewage treatment technologies, issues concerning testing of marine sanitation devices for type approval and issues concerning gray water. This workshop is intended to be an interactive exchange of information between policymakers, industry experts, and interested members of the public.
For more information on how to attend, please view the Federal Register notice (80 FR 62551).
(NEW!) Acceptance of CAP 437, Standards for Offshore Helicopter Landing Areas. The Coast Guard announces the availability of CG-ENG Policy Letter 03-15 which authorizes U.S.-flagged MODUs, floating OCS facilities, and vessels to utilize CAP 437 in lieu of the helicopter facilities standards in 46 CFR Part 108.
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.
