737-C730-02 REV A NAVIGATION LIGHTING ARRANGEMENT

B. DESCRIPTION OF WORK

The Contractor shall develop drawing 778-C317-01 MAST CONSTRUCTION and submit it to the Government for review and approval.

The Contractor shall provide and install a navigation light mast aft of the pilot house, a navigation light mast with gaff and yardarm on top of the pilot house, a forward navigation light mast on top of the pilot house, and a radar antenna mast on top of the pilot house. The Reference Drawings are provided as guidance on the masts design and installations.

Please note that the mast/navigation light arrangement provided with the Reference Drawings are for a vessel that operates solely on a “Western River.” Per 33 CFR, Part 89, Section 89.27(b), while transiting the Gulf Intracostal Waterway (GIWW), the vessel is required to display the standard inland lights for a vessel pushing ahead or towing alongside. This lighting arrangement is not shown on the Reference Drawings. The Contractor shall be responsible for designing and installing the navigation light masts in accordance with the U.S. Coast Guard Navigation Rules (COMDTINST M16672.2D) and 33 CFR, Subchapter E - USCG, Inland Navigation Rules.

The pilot house top mounted navigation light mast(s) shall hinge forward/aft. When in the hinged down position, the mast shall be located such that all lights may be serviced from the pilot house top. A mast rest cradle(s) shall be provided to support the mast(s) when it is in the down position. Navigation light cables shall be located such that the mast(s) may be lowered to the cradle without disconnecting the cables.

The pilot house top mounted navigation light mast shall incorporate a gaff and a yardarm. Both gaff and yardarm shall be fitted with staples, sheaves and halyards for flying both the USA and USACE ensigns. Galvanized cleats approximately 6 inches in length shall be provided to secure the halyards.

The radar antenna shall be mounted on a hinged mast, mounted on the pilot house top, with a support cradle positioned such that the antenna housing is below the height of the fixed searchlight. The radar mast shall be designed and fabricated for wind loading. The electrical connections shall be located such that they do not have to be disconnected when the mast is in the cradle.

Masts shall be designed to minimize vibration transmitted to mounted equipment.

C320 TANKS

Foundations shall be constructed and installed in accordance with the above Contract Drawings.

Please note that not all foundations are shown in the above Contract Drawings. The Contractor shall be responsible for providing suitable foundations under all units of equipment, machinery, tanks, deck fittings, winches, and other heavy concentrations of weight in order to properly mount the item, to distribute the loads to the structure, and to avoid undue stresses and vibrations in the hull.

Foundations shall be fabricated from structural steel shapes and plates. Foundation members shall be lightened and openings provided to permit access to all parts of the foundation for inspection, drainage, and maintenance. Web plates of foundations shall be stiffened at holding-down bolts and other points of load concentration.

Bolting surfaces on foundations shall be made coplanar by the use of machined steel shims or poured-in type chocking material. Bolt holes in foundations shall be templated from the unit.

Foundation top flanges/plates shall be level.

All equipment bolted to foundations shall have mounting bolt holes accurately bored (not burned) and reamed to provide a no-slop fit.

Where dripping of water or oil can be expected, the top plates of foundations shall be tight and project slightly beyond the edges of bedplates or bases of units to be supported. Flat bar shall be seal-welded around the edges of the top plates to retain any leakage of oil or water and quick disconnect fittings provided for drainage.

Any structural detail developed by the Contractor shall be supported with appropriate structural calculations. When requested by the COR, structural calculations shall be furnish to support details developed by the Contractor.

C400 OUTFIT

C401 GENERAL

Due to the nature of the operation, the vessel may be moored, unmanned, and unattended for extended periods of time. To the maximum extent possible, all materials, equipment, and outfit shall be vandal or tamper proof and theft-proof.

All deck fittings and deck equipment shall be properly mounted on dedicated foundations or insert plates welded continuously to the deck, with local support stiffeners backing up the regular deck structure as required.

C404 CORROSION PREVENTION

The choice of materials, the fabrication procedures, and the coating systems to be used in the fabrication of the vessel, shall indicate that careful consideration was given by the Contractor to improve corrosion resistance and life expectancy.

As an example, the structure shall be designed and fabricated to avoid corrosion, by effectively:

Insulating the contact surfaces between two dissimilar metals against galvanic corrosion.

Preventing the entrapment of water (facilitate drainage and avoid pockets where water can accumulate).

Facilitating the application of paint coatings (i.e. eliminate non accessible voids).

C406 COATING SYSTEM

Immediately upon completion of surface preparation, all steel shall be coated with the coating system described in this clause.

The Contractor can use either pre-construction primer or limit initial coating to base coat only. If initial coating with base coat is selected, prior to application of subsequent coats, all steel shall be sand swept clean (light blast) or water blasted and any damaged areas repaired prior to application of the remainder of the system. All areas needing repair shall be cleaned to bare metal, spot blasted to restore profile and re-coated with the base coat.

B. PAINT REQUIREMENTS

Paint shall be delivered in sealed containers with labels to indicate manufacturer, contents , expirations dates and any special instructions. Paints and painting materials shall be stored under cover and protected from extreme temperatures.

Paints shall not be used if they have exceeded the closed shelf or pot life, recommended by the manufacturer. Additionally, paints shall not be applied in weather or humidity conditions not recommended by the manufacturer.

C. APPLICATION OF COATINGS

Surface preparation and paint application shall be in strict compliance with the coating manufacturer’s recommendations. The Contractor shall take particular care to ensure that coating system requirements are met in all areas, especially those difficult to coat, such as flange undersides. All painting on both the interior and exterior surfaces below the main deck shall be accomplished prior to launching of the vessel.

D. COATING SYSTEM

The system is composed of the following coating types:

Self priming epoxy base coat Abrasion resistant epoxy barrier coat Fade…
