- CG 47 Class Aluminum Superstructure Task Force Request For Information (RFI) 1.0Overview The superstructure on the CG 47 Class Cruiser is constructed of aluminum alloys to meet stability and other naval architectural limit restrictions imposed by the DD 963 based hull and machinery plant. The CG 47 Class has experienced superstructure cracking. The cracks can be divided into two general categories as being attributed to (1) stress concentrations/aluminum fatigue, and (2) material degradation (sensitization) of the aluminum alloys. The CG 47 Class Aluminum Superstructure Task Force, created by the U.S. Navy to study various alternatives to best eliminate Superstructure Cracking issues on CG 47 Class ships, is being coordinated by the Commander, Naval Sea Systems Command, SEA 05 and SEA 21. The Task Force is assessing cost, schedule, and risk implications for the two options described below (see section 3.0), including wholesale superstructure replacement and replacing sections of the superstructure during CNO availabilities. 2.0Requirement This RFI will assist in programmatic decisions regarding options to address the urgent need for correcting cracking issues on twenty-two (22) in-service CG 47 Class Ships with minimal developmental and programmatic risk. This RFI is issued by SEA 05/SEA 21 as a means of market research, to obtain information regarding the assessment of technically viable options for addressing CG 47 Class superstructure cracking problems. This RFI is for planning purposes only and shall not be construed as a Request for Proposal (RFP), or as an obligation or intent by SEA 05/SEA 21 to acquire any products and/or services. SEA 05/SEA 21 does not intend to award a contract on the basis of this RFI. The information submitted in response to this RFI will assist in programmatic decisions to address CG 47 Class superstructure cracking problems. Request information on: Comments on the approach described Experience (pro/con) with aluminum welding Experience with repair of sensitized aluminum Experience (pro/con) with welding large aluminum inserts Modular aluminum fabrication and construction techniques Advanced or innovative production techniques Submission of a response to this RFI is entirely voluntary. The voluntary submission of a response to this RFI shall not obligate SEA 05/SEA 21 to pay, or entitle the submitter of information to claim any direct or indirect costs or charges or any other remuneration whatsoever. SEA 05/SEA 21 understands that any pricing information submitted under this RFI is an estimate only and is neither binding nor does it constitute a proposal. Responses to this RFI shall be submitted to POC listed in Section 6.0 via electronic mail (email) only by January 14, 2011. Responses received after this date may not be afforded a comprehensive review. Responses shall include the name, email address and telephone number of a point of contact having authority and knowledge to discuss responses with Government representatives. 3.0Background The CG 47 Class Superstructure Crack Task Force was initiated to implement a ninety (90) day study to assess technically viable options for addressing CG 47 Class superstructure cracking problems. The two options are outlined below. 3.1 Approach Option 1 - Repair Cracks as They Manifest (Status Quo) Provide repair data, experience, certifications, etc. Provide design data for work during unscheduled repairs or availabilities Estimate risk to other ship systems/interference impacts Evaluate means to ensure procured original design material will not sensitize Evaluate means to reduce cracking in sensitized material (Peening, Ultrasonic Impact Treatment, Coatings) Evaluate means to reduce or reverse sensitization in service (coatings, insulation, heat blanket) Evaluate welded and non-welded repair techniques (composite patches, friction stir welding) Evaluate other surface ship classes with aluminum superstructures to understand sensitization issues they may be experiencing and any noted differences or similarities Estimate material procurement risks Estimate safety risks 3.2 Approach Option 2 “ Partial Superstructure Replacement 3.2.1 Approach Option 2a - Remove and Replace Likely Sensitized Material Provide repair data, experience, certifications, etc. Provide design data for work during unscheduled repairs or availabilities Estimate risk to other ship systems/interference impacts Estimate cost and schedule to develop class-wide removal, replacement, and structures shipalts work package Estimate duration, cost, and cost/schedule risk for typical superstructure repair Estimate cost and schedule risks for tailoring common work package to individual ships Estimate material procurement risks Estimate safety risks 3.2.2 Approach Option 2b - Pre-Fabricate and Install Deckhouse Component Replacement Modules Provide repair data, experience, certifications, etc. Provide design data for work during unscheduled repairs or availabilities Define replacement module boundaries Develop ROM module designs Determine what systems will be pre-outfitted, and develop remove & reuse strategy for those that will not Estimate cost and schedule for module detailed design Estimate cost, schedule, and cost/schedule risk for module production Estimate cost, schedule, and cost/schedule risk for typical module installations Estimate cost and schedule risks for module installation to individual ships Estimate material procurement risks Estimate safety risks 4.0Data Requirements and Retention Policy The information requested is intended to include, but not be limited to, engineering and production techniques, planning and scheduling, material availability and cost, and other support information that would be helpful for making programmatic decisions. Any restrictive markings included on the data by a submitter will be adhered to by SEA 05/SEA 21. In responding to this RFI, data and information (drawings, documents, tables, graphs, etc.) may be submitted in various formats and media (paper or electronic files). Responders should specifically mark or identify any information they perceive as proprietary/confidential for which they seek added confidentiality. All proprietary information submitted in response to this RFI will be treated as business sensitive to the extent specified by the provider. 5.0Support Contractor Industry is advised that the following two (2) contractors provide support to the task Force. CG 47 Class Planning Yard, Northrop Grumman Ship Systems, in accordance with its prime contract with NAVSEA for planning yard services and as CG 47 class design agent, will provide support to the Task Force by preparing, refining, coordinating and analyzing all submitted information. Gibbs and Cox, subcontracted to Alion Science and Technology, provides structural analyses for this task force. Recommendations as to which repair option to pursue will be made by the Task Force. If additional support contractors will be involved, SEA 05/SEA 21 will notify each industry participant, who has submitted information, for release approval, prior to support contractor involvement. All SEA 05/SEA 21 support contractors, including the CG 47 Class Planning Yard, that are provided access to submitted information will be required to execute non-disclosure agreements.. 6.0Point of Contact: Angela Butler-Franco (SEA 02432) (202)781-1789 Angela.butler-franco@navy.mil
