*Per TI #2010-134 signed 30 Aug 2010

Task 2*

• Collect project technical data and industry best practice information. Collect and review open literature, class information, aluminum industry guidance and analytic[al] tools to produce an understanding of the current state of knowledge and practice. Based upon this review, develop an outline for the technical guide and circulate to the project technical committee for review and comment.

• Gryphon has a library of books, journal articles, specifications, design guides, etc., and we are in the process of obtaining additional relevant references.

• Deliverable: Draft Design Manual Outline (submitted to TPOC on Monday, 01 Nov 2010)

• Meeting: Committee Comment Discussion – Tuesday, 16 Nov 2010, Gryphon (80 M St.)

• Deliverable: Revised Design Manual Outline (submitted to TPOC on Monday, 22 Nov 2010)

Proposed Information Types / Sources

• Materials / Alloys – raw material suppliers; alloy producers; material industry societies

• Fabrication – extruding, casting, forming, machining facilities

• Welding – aluminum welders; welding societies

• Testing / Certification• Ship Designers / Ship Builders• Inspection / Classification Societies – ABS,

Lloyd’s, USCG, DNV• Universities

Task 3*

• After having received and consider[ed] feedback from the project technical committee, develop a guidance manual to support the design of large high speed aluminum ships. The guide will provide information related to materials and welding, detailing, marine loads on high speed craft and how these influence fatigue, fracture and ultimate strength of hull structures. The subject matter will be described at three levels of detail (e.g. rules of thumb, closed form and numerical modeling).

• Design guide will be developed with several focus areas (next slide).

Resolution of the SOW Differences

• SOW received from TPOC contains the following:▫ (3.1.1): “Industry input into the guide development shall be a priority.”

(not included in signed TI)▫ (3.1.3): “The design guide shall consider operational loading with

attention to localized pressure fluctuations, machinery to hull connection interface issues and shaft line / propeller loads of unique concern to high speed aluminum vessels.” (not included in signed TI)

▫ Gryphon recognizes that industry input is important to the success of this task and that the loading types described in 3.1.3 are commonly associated with high speed aluminum vessels. Therefore, we recommend including industry input and design guidance concerning the loading described in 3.1.3.

9/22/2010 Large High Speed Aluminum Vessels Design Guide and Training 14

Resolution of the SOW Differences (cont’d)• SOW received from TPOC contains the following:

▫ (3.1.5): “The design guide shall be in a format readily adaptable to adoption by a standards development organization. Adherence to the form and style standards from ASTM International’s ‘Blue Book’ is suggested. “ (not included in signed TI and differs from the next item)

▫ (5.4): “The Contractor shall provide a print ready master final report and an electronic copy, including the above deliverables, formatted as per the SSC Report Style Manual.” (not included in signed TI and differs from previous item)

▫ Gryphon recommends adherence to the SSC Report Style Manual for the Design Manual.

9/22/2010 Large High Speed Aluminum Vessels Design Guide and Training 15

Resolution of the SOW Differences (cont’d)• SOW received from TPOC contains the following:

▫ (3.3): “It is expected that the proposed technical document, training course syllabus preparation and delivery could be completed in an 18 month time frame. The delivery of a course from the course materials prepared in this project would be completed after the completion of the first of the year of the [contract] (e.g. in months 14 to 18).” (differs from signed TI)

▫ Gryphon notes the POP, as listed in the signed TI, is 12 months.
