GROUP 100 HULL STRUCTURE SECTION 101 GENERAL INFORMATION General The BUILDER is to construct the principal structure as described herein. All structure is to be constructed of ASTM A-36 or ABS Grade A mild steel. 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 Certificates shall be provided to the OWNER, along with location of the certified steel. 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. Boksa Marine Design, Inc. Lithia, Fl. (813) BMD Rev P0 Page of 64

14 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. The BUILDER is to ensure that precautions are taken to prevent rusting of exposed plate and new welds. Painting shall be conducted within 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, 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. Bottom, side and deck longitudinals and girders shall be continuous and fully aligned throughout the length of the vessel. Girders and deck longitudinals shall be continuous through transverse structures except as detailed in the PLANS in way of tank boundaries, watertight bulkheads, etc. No hull non-tight stiffeners shall end in mid-plate. All stiffener ends must be bracketed, clipped or lapped. Decks shall be reinforced with heavy inserts and framing in way of cleats, tow bitts, winches, etc. Insert plates shall in general be used in preference to doubler plates. Any use of doubler plates shall be approved by the OWNER. All deck openings shall have wellrounded corners in accordance with ABS guidelines, with a minimum radius of 3. SECTION 109 WELDING All welding, brazing and related procedures including joint design, joint strength calculations, edge preparation, fabrication, welding inspection and records shall be in accordance with the ABS Rules for Building and Classing Steel Vessels Under 90m in Length, latest edition.

All welds that are exposed to weather including air intakes shall be double continuous as described on the PLANS. 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.

SECTION 180 FOUNDATIONS The BUILDER shall design, construct and install foundations for all equipment and machinery installed in the vessel, in locations shown on the PLANS. All foundations shall be constructed so as to minimize weight. The design of foundations shall provide for alignment and other special criteria as may be specified by the OEM or regulatory bodies. Foundation design shall provide adequate strength to support and maintain alignment of the mounted equipment in its operational mode. Loadings to be considered in design of foundations shall include dry weight of equipment, weight of fluids, dynamic loadings induced by equipment in operation, weights of supported ancillary components and/or systems (e.g. wiring, piping, control equipment, safety shields), and ship motions (see SECTION 001). All foundations and supports for equipment and components with moving or rotating parts shall incorporate vibration isolation devices that will function under service environment and design load conditions defined in SECTION 001. Foundations shall incorporate suitable supports so as to prevent excessive or unusual vibration under the normal range of vessel operating conditions. All foundations shall be constructed so that positive and accurate alignment of equipment and components can be maintained. The rigidity of foundations and supporting structure shall be sufficient to prevent misalignment that would interfere with operation of the machinery and equipment and to preclude excessive vibratory motion or rocking on the foundation. Structural members of the hull shall be used as parts of the foundations. Foundations shall be adequately supported by, and braced to, the vessel s structural members so that equipment loadings are properly distributed. They shall be neatly finished, with extremities terminated on adjacent structural members to develop continuity and avoid hard points on adjacent structure. Foundations shall be constructed of the same material as the surrounding structure. All equipment bolted to foundations shall have mounting bolt holes accurately bored (not burned) and reamed to provide a no-slop fit which meets the manufacturer s requirements.
