On July 7, 2010, in response to a request from the Coast Guard, the National Offshore Safety Advisory Committee (NOSAC) issued the report “Recommendations for Dynamic Positioning System Design and Engineering, Operational and Training Standards”. The report recommended the Coast Guard establish minimum Dynamic Positioning (DP) reliability standards and contained draft guidance from the Marine Technology Society (MTS) DP Committee for Mobile Offshore Drilling Units (MODUs), logistics and construction vessels, which the MTS has since completed. On May 4, 2012, the Coast Guard published a notice of recommended interim voluntary guidance titled “Mobile Offshore Drilling Unit Dynamic Positioning Guidance” 77 FR 26562. The notice highlighted that DP incidents on MODUs can result in severe consequences including loss of life, pollution, and property damage and recommended owners and operators of MODUs follow MTS DP operations guidance for MODUs. In particular, the Coast Guard recommended owners and operators of MODUs operate within a Well Specific Operating Guideline (WSOG) while attached to the seafloor of the U.S. Outer Continental Shelf (OCS) and operate within its Critical Activity Mode of Operations (CAMO) during critical activities.
The Coast Guard recognizes that DP incidents on logistics and construction vessels also can result in severe
Until such time as there is a regulatory requirement, the Coast Guard recommends owners and operators of all vessels other than MODUs conducting OCS activities on the U.S. OCS voluntarily follow guidance provided in the “DP Operations Guidance Prepared through the Dynamic Positioning Committee of the Marine Technology Society to aid in the safe and effective management of DP Operations”, Part 2, Appendix 2, DP Project/Construction Vessels (July 2012)” or “Appendix 3, DP Logistics vessels (July 2012)” as appropriate. These documents are available at
The guidance contained in the notice is not a substitute for applicable legal requirements, nor is it itself a regulation. It is not intended to nor does it impose legally binding requirements on any party. It represents the Coast Guard's current thinking on this topic and may assist industry, mariners, the general public, and the Coast Guard, as well as other Federal and State regulators, in applying statutory and regulatory requirements. You can use an alternative approach if the approach satisfies the requirements of the applicable statutes and regulations.
