Vessels of Opportunity (VOOs) Commercial or naval vessels that are in the vicinity of the DISSUB and may be used as platforms to carry out SRDRS operations VOOs eliminate dependence on specially modified submarines (MOSUBs) or ships (MOSHIPs) Candidate VOOs include Offshore Supply Vessels (OSVs), Platform Support Vessels (PSVs), and Anchor Handling Tug-Supply (AHTS) Vessels A large pool of VOOs are available worldwide and will facilitate rapid rescue response 12/9/2008 SNAME Chesapeake Section 16
Vessels of Opportunity (VOOs) VOO Requirements Seakeeping Length: Beam: Personnel Accommodations: Available Deck Area Minimum Deck Strength Static Dynamic 220 ft (min) 40 ft (min) 25 persons (min) 98 ft x 34 ft (min) 614 lbf/ft 2 under LARS 512 lbf/ft 2 overall 1,024 lbf/ft 2 Position-Keeping Maintain position within a watch circle <500 ft radius using 4-point moor Pursuing change to Navy requirements to permit use of DP ships (ABS DPS-2 minimum) 12/9/2008 SNAME Chesapeake Section 17
Minimum Ship Methodology Methodology for quickly assessing whether the deck of a particular VOO has sufficient structural strength to support the installation of the SRDRS Common structural features of various VOOs used to create a longitudinally-framed and a transversely-framed paper ship Scantlings for these models calculated using the ABS Steel Vessel Rules (Under 90m) and the DNV Rules for Classification of Ships (Under 100m) Models analyzed for loads transmitted to the deck through the SITS using FEA These structural models create the complete Minimum Ship design Potential VOOs can be compared to these minimum ships in order to quickly assess their suitability as a platform for the SRDRS 12/9/2008 SNAME Chesapeake Section 18
What is Classification? Classification certifies adherence to a recognized set of technical standards Represents that marine facilities possess the structural and mechanical integrity required for the intended service as represented by the Class notation The classification process involves: Establishing industry accepted standards known as Rules Reviewing the designs against these standards Ensuring that the equipment is built in accordance with the approved plans and maintained to these accepted standards during their entire life cycle Marine facilities built to meet the requirements of the Rules are Classed 12/9/2008 SNAME Chesapeake Section 19
Who Provides Classification Services? Classification services are offered by independent third-party organizations known as Classification Societies Major Classification Societies include: American Bureau of Shipping (ABS) Lloyd s Register of Shipping (LRS) Det Norske Veritas (DNV) Germanischer Lloyd (GL) 12/9/2008 SNAME Chesapeake Section 20
Application of Classification to SRDRS ABS is working with the U.S. Navy to support the development, deployment, and operation of SRDRS Areas of involvement include: Classification of several elements, including the Launch and Recovery System (LARS), Deck Cradle, Umbilical Handling System, and Ship Interface Template Sets (SITS) Third-party independent design review and survey services for the pressure hull and Transfer Skirt of the Pressurized Rescue Module System (PRMS) Development of the minimum ship methodology for VOOs Survey support during deployment of SRDRS 12/9/2008 SNAME Chesapeake Section 21
Paradigm Shift for Navy Certification U.S. Navy Deep Submergence Systems traditionally certified to System Certification Procedures and Critieria Manual for Deep Submergence Systems ( P-9290 ) Appendix H allows for Handling System certification by ABS in lieu of NAVSEA Advantages of ABS Classification: On-site survey during construction (no SUPSHIP present at any SRDRS contractor sites) ABS Rules are modified more frequently and more quickly than P-9290 and other applicable Navy standards Time and cost savings during operations and maintenance over entire SRDRS life-cycle due to worldwide ABS presence Additional benefit discovered leverage ABS experience with potential VOOs to support time-critical rescue operations with 24/7 emergency response 12/9/2008 SNAME Chesapeake Section 22
Interface and Cooperation Unique nature of SRDRS certification required development of additional guidelines above P-9290 and ABS Rules NAVSEA-ABS Memorandum of Agreement Provides procedures for: Initial certification of components Sustaining certification of components Installation certification and deployment authorization of SRDRS aboard a VOO ABS-Plus Requirements Tailoring of existing Navy standards or modification of ABS Rules as agreed to by NAVSEA and ABS 12/9/2008 SNAME Chesapeake Section 23
Design Review and Surveys of ABS-Classed SRDRS Elements Conducted in accordance with the applicable requirements of: ABS Rules for Building and Classing Underwater Vehicles, Systems, and Hyberbaric Facilities (2002), Appendix 4 (Certification of Handling Systems) Other applicable Rules, such as ABS Rules for Building and Classing Steel Vessels ABS-Plus Requirements 12/9/2008 SNAME Chesapeake Section 24
System Testing and Acceptance ABS Surveyors provided on-site surveys during construction and witnessing of Factory Acceptance Tests in Vancouver, Baltimore, and Scotland ABS Surveyors provided installation certification in San Diego and Norway for sea trials and BOLD MONARCH ABS issued Class Certificates for the Handling System and SITS to support US Navy certification and delivery of the system ABS continues to support construction of additional SRDRS components (SITS and LARS) 12/9/2008 SNAME Chesapeake Section 25
SRDRS Sea Trials System successfully completed Navy certification sea trials in April 2008 Manned testing authorized 10 Mar 2008 Certified for manned use 17 Apr 2008 12/9/2008 SNAME Chesapeake Section 26
BOLD MONARCH 2008 Complete success off Norwegian coast May-June 2008 13 successful mates to Norwegian, Dutch, and Polish submarines 203 personnel transferred 12/9/2008 SNAME Chesapeake Section 27
Conclusions SRS-RCS provides mobile, rapidly deployable worldwide submarine rescue response, without the burdensome logistical trail of DSRV ABS involvement in classification and certification represents a paradigm shift for the Navy, leveraging commercial experience and interfaces with vessel owners International cooperation will grow the pool of candidate VOOs and improve rescue response timelines 12/9/2008 SNAME Chesapeake Section 28
