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 inLength 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 DuringConstruction”, latest edition. Plating shall be fitted fair and free from buckles or uneven sight edges. All formed plates or shapesshall be formed true to the required alignment, shape or curvature. Where flanges are used for attachments, the faying edges shallbe 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 compoundsshall 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 tocompensate for unfairness in the vessel structure. Every effort shall be exercised to construct a vessel with fair and undistortedsurfaces. This shall include diligence for careful fit-up, proper weld sequences and utilizing minimum weldments to achieve requiredstructural 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 equipmentshall be dressed or ground to avoid injury to operating or maintenance personnel or damage to equipment. Internal corners shall befilleted 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 removedand with rounded corners. Semicircular “rat holes” shall be provided in framing members in way of passing welded seams or butts inthe 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 detailsshall be used to maintain structural and fire insulation integrity and oil/water/air tightness as appropriate.The BUILDER is to ensure that precautions are taken to prevent rusting of exposed plate and new welds. Painting shall be conductedwithin a controlled environment, protected from the elements, through use of either permanent or portable structures.
Workmanship
The BUILDER is responsible for developing local strengthening, such as foundations and piping penetrations. Penetrations of deck,bulkhead, and shell plating shall be reinforced as required to maintain structural integrity. All rough edges, sharp corners, weldspatter, etc. shall be ground smooth. Where temporary attachments are removed, the surface shall be restored by welding andgrinding. Lifting pads shall be cut neatly and left in place for future use, except as directed by OWNER. Structures shall not beremoved with a hammer but rather by grinding away welds.

Before sealing run is applied to a butt weld, the clean metal of the originalroot 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 attachmentsare 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 bethoroughly 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 asrequired.
