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:
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. Comments should be submitted on or before November 29, 2013; for more information please see the Federal Register notice above. Upon reviewing comments received on this proposed policy letter, the Coast Guard will issue the final policy letter and specify its effective date.
Safety and Environmental Management System Requirements for Vessels on the U.S. Outer Continental Shelf. On September 10, 2013 the Coast Guard published a Federal Register Advance Notice of Proposed Rulemaking (ANPRM) to require vessels engaged in OCS activities to develop, implement, and maintain a vessel specific Safety and Environmental Management System (SEMS). The ANPRM (78 FR 55230) requests comments on the feasibility of implementing a SEMS that incorporates API RP 75, compatibility with BSEE SEMS regulations, and other issues of concern. The comment period is extended to January 23, 2014 by 78 FR 67326; for more information please see the Federal Register notice above.
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 has been updated by 78 FR 56837 to reflect a delayed effective date of January 16, 2014. Any questions regarding the categorization updates can be directed to Mr. Patrick Keffler at (202) 372-1424.
Alternate Design and Equipment Standard for Floating Offshore Installations (FOI) and Floating Production, Storage, and Offloading (FPSO) Units on the U.S. Outer Continental Shelf. Coast Guard CG-ENG Policy Letter No. 01-13 (26 June 2013) establishes an alternate design and equipment standard to 33 CFR 143.120(b) for both U.S. and foreign flagged FOIs and FPSOs located on the U.S. Outer Continental Shelf. The intent of this policy is to provide guidance to facilitate certification, as described in 33 CFR 143.120(c), of new FOIs and FPSOs that comply with the industry standards in enclosures (1) and (2) of this policy letter. The Coast Guard considers that the alternative standards described in this policy letter provide a level of safety equivalent to that required by regulation. CG-ENG will continue to consider requests for use of other alternatives on a case-by-case basis.
Electrical Equipment in Hazardous Locations on the U.S. Outer Continental Shelf (OCS). The Coast Guard published a notice of proposed rulemaking to amend 46 CFR Subchapter J ((78 FR 37760), published 24 June 2013) applicable to foreign Mobile Offshore Drilling Units (MODUs), floating facilities, and vessels that engage in OCS activities for the first time and newly constructed U.S. MODUs, floating facilities, and vessels, excluding offshore supply vessels. For more information please see the Federal Register notice above. The comment period for this rulemaking has been extended to November 30, 2013 (see (78 FR 58989), published 25 September 2013).
Electrical Equipment Certification
Guidance for MODUs. The Coast Guard published a Federal Register
policy on Mobile Offshore Drilling Unit (MODU) Electrical Equipment Certification
Guidance ((77 FR 71607),
published 03 December 2012) regarding electrical equipment
installed in hazardous areas on foreign-flagged MODUs that
have never operated, but intend to operate, on the U.S.
Outer Continental Shelf.

Following Macondo-Safety Enhancements on the U.S. Outer Continental Shelf"
Dynamic Positioning (DP) Guidance
for MODUS. In December 2011, the Coast Guard published a draft
policy letter on Dynamic Positioning (DP) Systems, Emergency Disconnect
Systems, Blowout Preventers, and related training and emergency procedures
on a Mobile Offshore Drilling Unit, and requested public comment. Numerous
comments were received, both as submissions to the docket and at a public
meeting. Upon review of the comments, the Coast Guard published a follow-on

FR 26562), published 04 May 2012) for MODU operators on the U.S. Outer
Voluntary Reporting of Dynamic Positioning (DP)
Incidents on MODUS. Coast Guard
CG-5PC Policy Letter 77 FR 26562 (19 June 2013) clarifies the protocol
in Federal Register Notice 77 FR 26562 ((77
FR 26562), published 04 May 2012) for voluntary reporting of MODU DP
incidents and outlines how the Coast Guard would use voluntary incident
reports to facilitate industry wide improvements to DP reliability by using
lessons learned from voluntary reports.
Dynamic Positioning (DP) Guidance for non-MODUs. In May 2012, the Coast Guard published a Federal Register Notice of Recommended Interim Voluntary Guidance for MODU operators on the U.S. Outer Continental Shelf.

5A Space Performance Guidelines and
Report of Study.
The 5A Space Performance Guidelines (Approved 09 January 2013)are intended to guide designers and operators in the design and maintenance
of Type “5A” spaces as equivalent to the structural fire protection
requirements in 46 CFR Subchapter K. NVIC 9-97, Change 1 (Guide
to Structural Fire Protection) calls for a performance based analysis,
these guidelines may be used instead. These guidelines were developed based
on fire test data and subsequent computer analysis as documented in the
Report of Study dated December 18, 2012, available in 5A Space Performance
Implementation Date for Carbon
Dioxide System Lock-Out Valve and Odorizer Requirements. Coast Guard
Letter No. 05-12 (07 September 2012) clarifies the application of the new
requirements for lock-out valves and odorizing units contained in the final

FR 33860) published 7 June 2012).
Equivalency Determination—Design Criteria for Natural Gas Fuel Systems.
CG-521 Policy Letter No. 01-12 (19 April 2012) establishes design criteria for natural gas fuel systems that provide a level of safety that is at least equivalent to that provided for traditional fuel systems by existing regulations. International standards for the design of natural gas-fueled ships are currently being developed by the International Maritime Organization (IMO). In June of 2009, the IMO published interim guidelines on safety for natural gas-fuelled engine installations in ships in
Acceptance of the 2009 MODU Code. For purposes of foreign MODU compliance with U.S. coastal state regulations, Coast Guard
CG-ENG Policy Letter No. 02-12 (07 May 2012) establishes that the design and equipment standards of the 2009 MODU Code are considered to be at least as effective as the design and equipment standards of the 1979 and 1989 MODU Codes. A foreign MODU in compliance with the design and equipment standards of the 2009 MODU Code may be accepted under 33 CFR 143.207(c).
