General Requirements for Hull and Structural Work. All new hull plating of any shape shall be fabricated from ABS Structural Steel or ASTM A36, “Specification for Structural Steel.” Contractor shall pay close attention to details in both the design and construction of all new and/or modified structures, to prevent structural discontinuities and other stress concentrations. Where openings must be provided in the structure to gain access internally, the Contractor shall provide adequate compensation to maintain the original structural integrity while the opening is present. All compensation shall be approved by the ABS. Watertight and oil tight integrity of all bulkheads and decks shall be maintained at all times throughout the period of performance of this job order. Openings created by permanent removal or addition of piping, wiring or other materials shall be closed by means of Watertight penetrations or insert plates of equal thickness flush-welded to the bulkheads. All welds shall be ground flush and smooth. Sections of stiffeners, beams, girders, etc., shall be welded to the bulkheads to maintain continuity of structure. Openings cut into decks and bulkheads shall be adequately compensated in accordance with ABS requirements to maintain original strength, unless the opening is cut in such a manner that it can be re-welded to existing framing members.
