HT-60 Harbor Tug 30 August 2019 Technical Specifications 8 Job 19005.01, Rev. A

074 WELDING

074.1 General

Careful consideration shall be given to assembly sequence and the overall shrinkage of plate 145 panels and assemblies, resulting from the processes employed. Welding shall proceed systematically with each welded joint being completed in correct sequence without undue interruption. Where practicable, welding shall commence at the center of a joint and proceed outwards or at the center of an assembly and progress outwards towards the perimeter so that each part has freedom to move in one or more directions. 150

Temporary welds incident to erection shall be carefully removed and flushed off by chipping or grinding.

Intermittent welding may be used where appropriate to minimize distortion and where oil-tightness or water-tightness is not required. However, intermittent welding shall not be used in locations exposed to the weather or water. 155

Structural welding will be carried out in such sequence as to compensate for shrinkage as the work progresses, prevent locked in stresses, and minimize distortion.

Structural steel may be manual or machine welded, depending on the Contractor’s standard practice.

Welds shall be neatly finished, with all spatter and slag removed, and ground flush where 160 required.

Welding bead sizing, lengths, and spacings shall be in accordance with ABS Rules for Building and Classing Steel Vessels Under 90 meters (295 feet) in Length.

074.2 Preparation

The preparation of plate edges shall be accurate and free from blemishes. Joints shall be properly aligned and closed or adjusted before welding. Means shall be provided for holding 165 the work in proper alignment without rigid restraint during welding operations. Excessive force shall not be used in fairing and closing the work. Where excessive gaps exist between surfaces or edges to be joined, the corrective measures adopted shall be to the satisfaction of the Owner.

Before a manual sealing run is applied to the back of the weld, the original root run shall be cut back to sound metal. 170

Joint edges shall be scratch-brushed (or other acceptable method) immediately before welding to remove oxide or adhering films of dirt and filings.

074.3 Cleanliness and Environment

The surfaces in way of all parts to be welded shall be made clean, dry, and free from grease and other contaminants that might adversely affect weld quality, by cleaning with suitable chemicals or solvents. 175

The welding environment shall be in accordance with AWS D1.1, Section 5.12. Adequate protection shall be provided where welding is required to be carried out in exposed positions

HT-60 Harbor Tug 30 August 2019 Technical Specifications 9 Job 19005.01, Rev. A in wet, windy, or cold weather. Special precautions shall be taken to protect the building area from contamination by dissimilar metals (e.g., iron, steel, and copper).

074.4 Tack Welding

Consumables for tack welding shall be of the same grade as those used for the main weld. 180

Tack welds that are to be retained as part of the finished weld shall be clean and free from defects before being incorporated into the weld.

Care shall be taken when removing tack welds used for assembly to ensure that the material of the structure is not damaged.

Any defects in the structure resulting from the removal of temporary attachments shall be 185 prepared, welded, and ground smooth so as to achieve a defect-free repair.

074.5 Alignment and Fit

Workmanship shall result in fair lines and smooth surfaces.

Structure shall fit tightly without excessive gaps between seams, buckles, kinks or other surface irregularities.

Care shall be taken to obtain good alignment of structural members, particularly where such 190 members oppose each other on opposite sides of bulkheads or decks. Alignment shall comply with the tolerances specified in the IACS Rec. No. 47, Shipbuilding and Repair Quality Standard. Additionally, any cases where misalignment exceeds half the thickness of the thicker member shall be considered deficient and require correction. Where discontinuities of structure are unavoidable, suitable brackets or other reinforcement shall be installed. 195

The Contractor shall take every precaution to keep distortion and welding stresses to a minimum. Excessive unfairness in plating may be corrected by local spot-heating and quenching, provided such methods are approved by the regulatory bodies. Deviation and distortion of structural material shall, in general, be within the tolerances prescribed in IACS Rec. No. 47, Shipbuilding and Repair Quality Standard. Hull plating and all decks, interior 200 and exterior, shall have a maximum deformation of 1/8" between frames.

Shims, liners, “dutchmen,” or “sleepers” shall not be used for correcting improper fit. Clamps with wedges or strong-backs used for this purpose shall be suitably arranged to allow freedom of lateral movement between adjacent elements. Welded temporary attachments used to aid construction shall be removed carefully. 205

075 MATERIALS

Materials, machinery, and equipment provided by the Contractor shall be new, of current manufacture, and currently supported by spare parts readily available in the United States of America.

Materials, machinery, and equipment provided by the Contractor shall be of commercial marine quality, in full conformity with the technical requirements of this specification, and 210 suitable for the intended use.

HT-60 Harbor Tug 30 August 2019 Technical Specifications 10 Job 19005.01, Rev. A

Critical vessel equipment shall have technical service available in New York State. Critical vessel equipment consists of main engines and Z-drives. All other systems shall have technical support available in the United States of America.

Dissimilar metals (not electrolytically compatible) shall not be directly joined. Electrolytic 215 corrosion shall be prevented by insulating dissimilar metals from one another by way of gaskets, washers, sleeves, or bushings made of insulating materials.

Except for machinery foundation shims, faying surfaces between materials (i.e. metals, laminates, or any combination thereof), shall be protected by the use of bedding compound(s) plus one coat of primer. Faying surfaces between wood and other materials shall be protected 220 by use of wood preservative-fortified bedding compound.
