Vessels of Opportunity (VOOs)

Commercial or naval vessels that are in the vicinity of theDISSUB and may be used as platforms to carry out SRDRSoperations

VOOs eliminate dependence onspecially modified submarines(MOSUBs) or ships (MOSHIPs)

Candidate VOOs include OffshoreSupply Vessels (OSVs), PlatformSupport Vessels (PSVs), and Anchor

Handling Tug-Supply (AHTS) Vessels A large pool of VOOs are available

worldwide and will facilitate rapid

rescue response

Minimum Ship Methodology

Methodology for quickly assessing whether the deck of aparticular VOO has sufficient structural strength to supportthe installation of the SRDRS

Common structural features of various VOOs used to create

a longitudinally-framed and a transversely-framed papership

Scantlings for these models calculated using the ABS SteelVessel Rules (Under 90m) and the DNV Rules forClassification of Ships (Under 100m)

Models analyzed for loads transmitted to the deck throughthe SITS using FEA

These structural models create the complete Minimum Shipdesign Potential VOOs can be compared to these minimum ships in

order to quickly assess their suitability as a platform for the

SRDRS

19/29

What is Classification?

Classification certifies adherence to a recognized set oftechnical standards

Represents that marine facilities possess the structural

and mechanical integrity required for the intendedservice 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 theapproved plans and maintained to these accepted standardsduring their entire life cycle

Marine facilities built to meet the requirements of theRules are Classed


7/27/2019 46afe7d1fa0f4965bac5acb439f46028

20/29

Who Provides Classification Services?

Classification services are offered by independentthird-party organizations known as ClassificationSocieties

Major Classification Societies include:

American Bureau of Shipping (ABS)

Lloyds Register of Shipping (LRS) Det Norske Veritas (DNV)

Germanischer Lloyd (GL)


7/27/2019 46afe7d1fa0f4965bac5acb439f46028

21/29

Application of Classification to SRDRS

ABS is working with the U.S. Navy to support thedevelopment, deployment, and operation of SRDRS

Areas of involvement include: Classification of several elements, including the Launch

and Recovery System (LARS), Deck Cradle, UmbilicalHandling System, and Ship Interface Template Sets

(SITS)Third-party independent design review and survey

services for the pressure hull and Transfer Skirt of thePressurized Rescue Module System (PRMS)

Development of the minimum ship methodology forVOOs

Survey support during deployment of SRDRS

Paradigm Shift for Navy Certification

U.S. Navy Deep Submergence Systems traditionallycertified to System Certification Procedures and CritieriaManual 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 thanP-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 experiencewith potential VOOs to support time-critical rescueoperations with 24/7 emergency response


7/27/2019 46afe7d1fa0f4965bac5acb439f46028

23/29

Interface and Cooperation

Unique nature of SRDRS certification requireddevelopment of additional guidelines above P-9290and ABS Rules

NAVSEA-ABS Memorandum of Agreement

Provides procedures for:

Initial certification of components Sustaining certification of components

Installation certification and deployment authorization of SRDRSaboard a VOO

System Testing and Acceptance

ABS Surveyors provided on-sitesurveys during construction andwitnessing of Factory Acceptance

Tests in Vancouver, Baltimore, andScotland

ABS Surveyors provided installationcertification in San Diego and Norway

for sea trials and BOLD MONARCH ABS issued Class Certificates for the

Handling System and SITS to support

Conclusions

SRS-RCS provides mobile, rapidly deployableworldwide submarine rescue response, without theburdensome logistical trail of DSRV

ABS involvement in classification and certificationrepresents a paradigm shift for the Navy, leveraging

commercial experience and interfaces with vesselowners

International cooperation will grow the pool of

candidate VOOs and improve rescue responsetimelines
