Task – T2455523 Class No.: TBD Shipyard: TBD / Hull No.: TBD Flag: United States of America Subject: Deck Cargo Barge

Attention: Mr. Joshua Sebastian, The Shearer Group, Inc. (442598)

The document shown in the attached list is reviewed in accordance with the applicable requirements of the following:

• ABS Rules for Building and Classing Steel Barges, 2022.

• ABS Rules for Building and Classing Marine Vessels, 2022.

Please note our review is based on the following conditions:

1. At your request, we have carried out an “Approval in Principle” review of the documents in the attached list.

2. The hull structural drawings are also subjected to a Statement of Compliance review for compliance with ABS Ice Class C0 as per your request.

3. The primary objective of this review is to establish compliance in principle with the applicable ABS Rules, insofar as they relate to the details submitted, that when all other requirements have been satisfactorily met, the barge will be eligible for the proposed Class notations: À A1, Barge, Great Lake Service.

4. It is also to be noted that before final approval can be granted, the proposed design will need to be verified against the Rules, Regulations and Standards applicable at the time that the contract for construction is signed or the keel is laid, as applicable.

5. The markups made on the document are to be incorporated in the final design that will be submitted for approval.

6. Please note that our review at this time in no way precludes any future amendments which may be deemed necessary due to submittal of additional information, clarification or drawing revisions during detailed engineering review for the subject design.

7. ABS would be prepared to class the final design of this concept when the relevant design drawings, calculations and documents are submitted for review on completion of the detailed engineering, and after ABS surveyors have attended the fabrication survey during the construction and installation. Subsequent maintenance of Class will be subject to satisfactory in-service inspection by ABS Surveyors as required for Classification.

8. Main Deck structure reviewed for an uniformly distributed deck loading of 3,000 lbf/ft2.

Please refer to the attached list of comments associated with this review.

TBD [Open] Technical

As deck pressure rating exceeds 2000 PSF, calculations for still-water bending moment are to be submitted in accordance with ABS Steel Barge

Rules 3-2-1/7.

TBD [Open] Technical

We note your request for a Statement of Compliance review of the structural drawings in accordance with applicable requirements for the Ice

Class C0. In this regard, the following items require further design change

(or) clarification.

1. The material and material grade are to comply with ABS MVR 6-1-

5/33. Grade of material for the deck plating and gunwale, sheer strake and deck stringer are to be revised.

2. Connection details in way of the upper turn of the bilge, which is within the ice belt zone, is to be made flush so as to avoid any damage during operations in first year ice.

3. Side shell longitudinals' collar plates in way of transverse webs are to be either shifted close to side shell, or a full collar plate is to be provided as to avoid soft patch within the ice belt region.

4. End connections in way of the webs and stiffeners within ice belt region are to be well developed. These members are to be attached and bracketed such that the Rule required net shear area in way of these end connections are satisfied. Refer to ABS MVR 6-

1-5/13.5 & 15.

S-014 888-B309-01 - Transverse Structure TBD [Open] Technical

The intermediate bottom shell longitudinal stiffeners in way of the bow region noted to terminate at Fr. 4 as per the bottom plan (888-B305-01, Sheet 2). The typical section does not show relevant end connection details for the intermediate stiffeners. In this regard, additional details for the bottom structure in way of Fr. 4 are to be included in the drawing for review.

S-015 888-B311-01 - Longitudinal Structure TBD [Open] Technical

It is noted that there is no shear connection provided between the deck transverse and the centerline longitudinal bulkhead for the bulkhead to be considered as an effective support for the considered span and provided section modulus (ABS SBR 5-1-1/7). In this regard, a collar plate is to be provided as shown in the Detail 3-23C (on Page 3) of the drawing.

S-016 888-B307-01 - Shell Plating TBD [Open] Technical

We note your request for a Statement of Compliance review of the structural drawings in accordance with applicable requirements for the Ice

Class C0. Bow arrangement does not include deep or intercostal stringers as required by ABS MVR 6-1-5/13.9. Please revise.
