Passageways shall be kept as clear of obstructions as possible.

Rigging of said hosed, welding leads, temporary lighting, etc., through water tight and fire boundary doors shall be prohibited. If these boundaries are utilized all hose, welding leads, lighting, etc., shall be arranged/configured to be breakable at these boundary points to allow closure of water tight and fire boundary doors in the event of fire and/or flooding incident.

5.9.9 Miscellaneous Safety Requirements

Material brought onto the ship shall be stored until used in areas which do not interfere with access to firefighting equipment or personnel access. Crating and packing shall be removed prior to bringing the equipment or material aboard the ship, unless needed to protect the equipment or material from damage during handling. In that case, the crating and packing shall be removed from the equipment or material, and shall be removed from the ship, immediately after being brought aboard.

All temporary openings into the vessel shall be marked and protected at all times. Tarps and temporary doors shall provide 100% protection of the openings (overhead and sides) except for the short durations when lifting operations are underway. Steel coamings shall be installed around each deck opening to prevent water intrusion into the space. Coamings shall be suitably sealed to prevent any leakage into the space.

The Contractor shall protect dangerous areas, such as access openings in the deck, with suitable temporary hand rails, and take all necessary and reasonable safety precautions to prevent injury to any person who may enter the work area for any reason.

5.10 COMPLETION OF WORK & VESSEL RECONSTITUTION

5.10.1 Completion of Work

The Contractor shall complete all contracted work by 1800 hours on the work completion date shown on the contract documents with the vessel clean and free of defects and deficiencies and the final joint condition survey punch list work completed.

The vessel shall be complete and ready for service, afloat pier-side, with all its areas (related to contract work) thoroughly cleaned and free of all dunnage and dirt. Potable water tanks shall be filled to capacity (accomplished by the Governments crew) and any diesel oil or similar fluids removed from the vessel to accomplish the contracted work, which would otherwise have been retained by the Government, shall have been replaced by the Contractor.

A timetable for completion of work on a revised final joint condition survey punch list will be agreed to between the COR and Contractor. The Contractor shall provide, prior to acceptance, the Coast Guard approved stability guidance necessary for the vessel to commence an operational schedule.

5.10.2 Compartment Closeouts

After all work on the vessel is substantially complete, each compartment in the vessel affected by the contracted work shall be inspected with an COR present to check fixtures, lighting, HVAC controls, cable penetrations, labeling, coatings, joiner doors, outfitting, and other miscellaneous items in the compartment. A preliminary inspection shall take place prior to installing or replacing the overhead panels.

When a compartment has been proven satisfactory to the COR, the compartment shall be “closed out” by locking or otherwise preventing general access to the space.

5.10.3 Vessel Reconstitution

During this time, crew will move tools, equipment, personal belongings, etc. aboard the vessel. The Contractor shall provide pier-side crane service and fork lift service during this time to facilitate vessel reconstitution. The Contractor shall move the storage containers possessing vessel equipment/supplies from their storage site to a location in close proximity to the ship for unloading.

6 SPECIFICATION REQUIREMENTS

The provisions of this subsection apply throughout the specifications and to all addenda, appendices, and change orders, unless specifically exempted.

6.1 STRUCTURAL MODIFICATIONS

6.1.1 Workmanship

The arrangements and scantlings of the structure shall be as shown on the drawings. The structural drawings have been developed in accordance with the rules of the American Bureau of Shipping (ABS), and any development of details shall maintain the same standards. Where details and scantlings are not shown, those in the existing vessel are to be used where applicable, but all details and scantlings must meet ABS requirements.

Care shall be taken to obtain good alignment of structural members, particularly where such members oppose each other on opposite sides of bulkheads or decks. In such cases, misalignment exceeding half the thickness of the thicker member shall be considered cause for rejection. Where discontinuities of structure are unavoidable, suitable brackets or other reinforcement shall be installed.

Within tanks, cofferdams, and peaks, and in any other spaces or areas that could trap liquids, adequate limbers shall be provided to ensure effective drainage. Similar limbers shall be cut in the framing members at the tops of tanks to prevent air pockets. Semi-circular “rat holes” are to be provided in framing members in way of passing welded seams or butts in the attached plating.

Where it is necessary to provide holes for passage of wiring, piping, or ductwork in structural members, compensation shall be provided where appropriate. In general, if such holes remove more than 30% of the depth of the web of a member or if they are unfavorably located, reinforcement will be required.

Where reinforcement is required in way of penetrations of decks, shell bulkheads or framing members, the use of doublers shall be avoided in favor of insert plate or reinforcing rings. Wherever insert plates are used, rounded corners with a radius of not less than 3" are to be provided. Cuts in strength decks or the shell shall be radiused at the corners as shown on the drawings or, where not indicated, with a radius of 1/8 the transverse dimensions of the opening not to exceed 24". Trunks and coamings in general should be worked with corners rounded to a 3" radius. In longitudinal structural bulkheads and in deckhouse sides, the radii shall be 1/8 the vertical dimensions but not exceed 6". In main transverse structural bulkheads, the radii shall be equal to 1/20 of the vertical dimensions of the cut, but radii need not exceed 6" and shall not be less than 1".

Shims, liners, “dutchmen,” or “sleepers” shall not be used for the purpose of correcting improper fit.

All penetrations of fire boundaries shall be collared as appropriate to meet the requirements of their particular classification or regulatory body requirements.

6.1.2 Foundations

Strength and rigidity of all foundations shall be sufficient for the weight of the equipment, including operating fluids, weight of supported ancillary components, and dynamic loading induced by vessel motion and equipment operation.

Foundations shall be made from steel plate and shapes, welded together and to the ship’s structure. Foundations shall be attached to primary structure, which shall be stiffened where necessary to carry both static and dynamic loads. Foundation design and construction shall account for variations in the flatness of the existing, decks, bulkheads, frames, etc. For example, foundations may need to be scribbed to match waviness in a deck in order to achieve effective connection of a flat mounting surface for equipment.

Items weighing less than 100lbs may be supported by foundations or bracket assemblies, as appropriate for the installation and adjoining structure.

6.2 PIPING MODIFICATIONS

6.2.1 General Requirements

All new and modified piping systems shall comply with ABS Rules, SOLAS and USCG regulations, The World Health Organization Guide to Ship Sanitation, and CDC Vessel Sanitation Program Standards. Other applicable regulations and standards are listed in 3.1 of these specifications. All valves, flanges, and fittings shall be supplied by manufacturers acceptable to those agencies.

All new piping is assumed to be of the same materials and construction methodology as currently exists on the vessel, unless otherwise specified. All new overboards shall be 316L stainless steel.

Piping systems utilizing mechanical connections that have ABS, USCG, and SOLAS approvals for the appropriate service may be substituted with the approval of the COR.

Piping systems and related material shall be designed, furnished, and installed as necessary to ensure complete and efficient operation of all systems, components, and machinery under all conditions of service.

Except where open ceiling systems are intended, all piping in accommodation spaces shall be concealed behind ceiling panels and sheathing as much as possible. In order to maintain maximum headroom, all piping shall be kept behind framing and as close as practical to deck beams, bulkheads, and the underside of decks. Piping may pierce girders, provided approved compensation is made at the penetration.

Welded joints shall be incorporated in the design to the maximum extent consistent with maintenance requirements of system components. Where piping is connected to machinery and equipment, provision shall be made so that stresses due to expansion and contraction of piping are not transmitted to the machinery or equipment.

The selection and application of thermal insulation and lagging for all new and disturbed previously insulated piping shall be in accordance with ASTM F683, Standard Practice for Selection and Application of Thermal Insulation for Piping and Machinery, except as specifically required otherwise by the specifications. The following systems shall be thermally insulated against sweating:

• Chill water

• Fresh water cooling

• Potable water (hot and cold)

• Refrigeration (both stores and scientific refrigeration)

• Seawater cooling

6.2.2 Materials

Materials for the various piping systems shall be in accordance with the applicable sections of these specifications and/or shall match existing systems on the vessel and/or as indicate din the specification. ABS Rules and USCG regulations, in conjunction with ASTM F1155, shall be used in selecting materials. Where allowed by Regulatory Bodies and where feasible, piping replacement for they Gray and Black water system shall be replaced with SeaCor material.

Galvanized material shall generally be done by the “hot dip” process; per ASTM A123 and/or A153 as appropriate. Galvanizing damaged during installation shall be repaired in accordance with ASTM A780.

6.2.3 Corrosion Precautions

Piping conveying corrosive media shall be protected from the effects of corrosion and/or corrosion-erosion by the adoption of the following:

• Type valves and fittings in nonferrous piping runs shall be bronze or a material compatible to the applicable piping material.

• Connections between ferrous and nonferrous metal pipe shall be made with a “waster piece” to limit the effects of galvanic corrosion. The waster piece shall be made of

Schedule 160 black pipe with flanged ends and shall be at least 2.5 times as long as the nominal pipe size.

• In lieu of a waster piece, an insulated coupling may be installed between the dissimilar metal lines.

• Turbulence of flow(s) shall be minimized to curb corrosion/erosion by restricting…
