2. Objectives:

The MV-RANGER III is assigned American Bureau of Shipping (ABS) Class Notation +A1, E, +AMS, Great Lakes Service and is designated a Subchapter H passenger vessel under 46 CFR 70-89. The vessel is also inspected under portions of Subchapters D-Tank and I-Miscellaneous Cargo of 46 CFR. Due to this classification the vessel is required to go to dry dock on a 5 year schedule per USCG and ABS regulations. During the dry-dock period the vessel undergoes other repairs as necessary to maintain or replace major components to take advantage of the dry-dock, available funds, and expertise.

3. Place of performance:

The dry-docking and all work performed shall take place at a facility located on Lake Superior or Lake Michigan.

4. Period of performance:

The period of performance will be approximately 90 days starting with the delivery of the vessel to dry-dock. All work that must be done in a drydock must be completed on or about December 09, 2023, with the option that some work that does not require drydocking may be done after the ship’s return to Houghton, MI

5. Scope:

The contractor shall furnish all labor, materials, equipment, blocking, staging and tools necessary to accomplish the 5-year mandatory dry-docking inspection of the Ranger III to include all necessary repairs.

6. Delivery:

All reports required by this SOW shall be delivered to the NPS COR, in both hard copy and digital (PDF), prior to departure from the contractors’ facility.

All drawings, sketches and reports, test results, test reports, inspection reports, hull survey, USCG Stability Book, MS Excel Stability Programs, load charts etc. prepared by the contractor in conjunction with the work items specified shall become the sole property of the NPS, including the design and engineering pertaining thereto.
