3.6 ARCHITECT-ENGINEERING SERVICES

Awardee shall supply a qualified Architect-Engineering (AE) firm to provide Schematics, Design Development, Construction Documents, Technical Specifications, Construction Period Services, Site Visits, Cost Estimates, As-Built Documentation, and all other related information for installing the new davit on the 01 Level of the NOAA Ship Oscar Dyson.

This includes any additional supporting structure and/or relocation of existing deck fixtures to safely accommodate the davit, its control station, and any associated ancillary equipment.

3.6.1 All planned locations and weights added to the NOAA Ship Oscar Dyson via the davit, associated equipment, and its additional supporting members will be summarized in a table and provided to NOAA’s Naval Architect, Port Engineer, and Captain.

3.6.1.1 Detailed plan for the addition of permanent ballast, if necessary.

3.6.2 Provide Drawings and Specifications for Peggy D. Davit. Develop modification and installation drawings (structural, electrical and mechanical) and detailed specifications for work.

3.6.2.1 All design work shall be submitted to and approved by ABS by the contractor.

3.6.3 Four freeing ports in the wet lab, below the 01 Deck, where the Peggy D is located, were welded shut in 2009. Update the Trim and

Stability Booklet to reflect these changes. Provide approval letter from ABS that these changes are acceptable. If these changes are not acceptable, write a condition found report with a recommended action plan and submit to the Port Engineer, Captain of the Oscar Dyson, and NOAA’s Naval Architect.

3.6.3.1 The following is a comment from NOAA’s internal fleet inspection team. The purpose of this section is to resolve this comment:

Four ABS required freeing ports, measuring 368,000mm2 in the Wet lab bulkhead have been welded shut. Two freeing ports measuring 250,402mm2 have been added to the aft bulkhead. This configuration is in violation of the requirements of the ABS damage stability review found in letter T-8-2 dated July 17, 2003. This letter required 368,000mm2 freeing ports in the Wet Lab to remain within the limiting KG during damage. This arrangement violates the stability letter which states "Results indicate that the stability of the OSCAR DYSON, as presently outfitted and equipped, is satisfactory for operation on Exposed Waters, provided that the operating and loading restrictions delineated in the following document (Trim and Stability Booklet) are strictly observed:" Operating Instruction number 7 of the Trim and Stability Booklet states: "All freeing ports shall be maintained operable and completely unobstructed at all times." The Port Engineer reports that a 1-½ inch drain has been installed in the wet lab. Verification that this is sufficient drainage to meet the stability requirements of ABS should be obtained and presented to close this item. Approval from ABS has still not been received. (Reference: 46 CFR §173) For 2012 inspection, a request was made by the inspection team for the ABS approval documentation to close out this item. No documentation was available. This documentation needs to include documentation of the submittal of the details of the change to ABS as well as the ABS approval letter)
