About this file

This document is a set of technical specifications for the construction of a 65-foot fisheries research vessel for the Michigan Department of Natural Resources (DNR). The vessel will have twin diesel propulsion, a steel hull, and an aluminum superstructure. It will accommodate six crew members and be used for fisheries research. The specifications provide details on the vessel's principal dimensions, tank capacities, performance, construction, and outfitting, including the propulsion system, electrical systems, machinery, piping, and accommodations. The solicitation for this project, titled "MI Dept. of Natural Resources-New Fisheries Research Vessel," includes an addendum extending the bid due date to February 29, 2024, and clarifying that while the DNR prefers a one-year completion date, they will evaluate bids with alternate timelines proposed by responsive and responsible bidders based on qualifications, experience, cost, and other factors.

The solicitation is open to qualified shipyards and does not require performance bonds. The DNR will evaluate bids based on the best overall value, considering factors such as the bidder's qualifications, experience, and the proposed completion timeline. The vessel will be funded and owned by the Michigan DNR, and no specific funding source or set-aside requirements are mentioned.

All welds in the hull shell are to be left unground. All exterior welds on the superstructure are to be left unground. All steel shall be wheel‐abrated and pre‐primed. Steel and Aluminum Certificates shall be provided to the OWNER, along with the location of the certified steel and aluminum.

All workmanship and welding shall be in accordance with the following:

Vessel to be designed and built in accordance with the ABS Rules for Building and Classing Steel Vessels Under 90 meters in Length but the vessel will not be classed or receive a Load Line assignment.

QUALITY AND FAIRNESS

Construction details shall be in accordance with ABS’ “Guide for Shipbuilding and Repair Quality Standards for Hull Structures During

Construction”, latest edition. Plating shall be fitted fair and free from buckles or uneven sight edges. All formed plates or shapes shall be formed true to the required alignment, shape or curvature. Where flanges are used for attachments, the faying edges shall be beveled and free from hollows.

Shims shall not be used to correct improper fit. Members shall be in alignment before welding is undertaken. No fairing compounds shall be used. Warpage or distortion that prevents the installation of the final welded assembly into the vessel is not acceptable.

"Panting" or "oil‐canning" of any panel in shell, deckhouse or decks is not permitted. Filling compound shall not be used to compensate for unfairness in the vessel structure. Every effort shall be exercised to construct a vessel with fair and undistorted surfaces. This shall include diligence for careful fit‐up, proper weld sequences and utilizing minimum weldments to achieve required structural strength.

The maximum unfairness between hull, deck and house stiffeners shall be t/2, where “t” is the plate thickness.

Penetrations of deck, bulkhead, and shell plating shall be reinforced as required to maintain structural integrity.

All cuts shall be neatly and accurately made with edges cleaned for welding. All sharp edges exposed to personnel or equipment shall be dressed or ground to avoid injury to operating or maintenance personnel or damage to equipment. Internal corners shall be filleted and external corners shall be rounded off. Ragged edges or sharp projections shall be removed.

All burning of notches and holes in the structure shall be carefully laid out and shall be regular in outline with jagged edges removed and with rounded corners. Semicircular “rat holes” shall be provided in framing members in way of passing welded seams or butts in the attached plating. Notches and rat holes shall be machine cut.

Where it is necessary to provide holes for passage of wiring, piping or ductwork through vessel structure, special penetration details shall be used to maintain structural and fire insulation integrity and oil/water/air tightness as appropriate.

Penetrations of deck, bulkhead, and shell plating shall be reinforced as required to maintain structural integrity. All rough edges, sharp corners, weld spatter, etc. shall be ground smooth. Where temporary attachments are removed, the surface shall be restored by welding and grinding. Lifting pads shall be cut neatly and left in place for future use, except as directed by OWNER. Structures shall not be removed with a hammer but rather by grinding away welds.

Welding shall be performed in a sequence that precludes significant locked‐in stresses and produce surfaces that are fair and free of buckles, bulges and other surface irregularities.

The surface of all parts to be welded shall be clean, dry and free from rust, scale and grease. Care shall be taken to ensure thorough penetration and fusion; undercutting is to be avoided. Before sealing run is applied to a butt weld, the clean metal of the original root is to be exposed. All welds not meeting these conditions shall be cut out and re‐welded.

All finished welds are to be uniform and free from defects such as slag inclusions, porosity, incomplete penetration, or undercutting.

New welds shall be treated within 24 hours to remove slag and paint with primer to prevent rusting. Where temporary attachments are removed, the surface shall be restored by welding and grinding.

Complete visual inspection of all butt and fillet welds shall be carried out by supervising authorities. All shell welds are to be thoroughly cleaned and staging is to be provided for access thereto. The Owner reserves the right to employ radiography or other non‐destructive testing of shell butt welds at a suitable stage of construction. The Builder is to provide access and assistance as required.

855‐832‐01

Defective welds are to be opened up and examined to determine the extent of defect, and subsequently re‐welded. If defects are other than limited, the Builder shall be responsible for further radiography to establish local extent.
