000 Introduction

010 General

The New York Power Authority (hereafter referred to as NYPA or the Authority) is the nation’s largest state

power organization, controlling 16 power generation plants, including fossil-fueled and hydro-electric

generating facilities. Among those facilities are the Robert Moses Niagara Power Plant and the Lewiston

Pump-Generating Plant. These plants utilize water diverted from the upper Niagara River to produce

electrical power for NYPA customers.

In a joint effort with the Ontario Power Generation utility, NYPA is responsible for installation and removal

of an 8,800-foot-long floating ice boom designed to accelerate the formation of the natural ice arch that

forms most winters near the head of the Niagara River and also stabilize the arch once it has formed. The

ice boom reduces the severity and duration of ice runs into the Niagara River, thereby lessening the

probability of large scale ice blocking in the river. Such blockages could lead to both hydropower generation

reductions and shoreline property flooding. In addition, it reduces the probability of ice damage to docks

and other shore structures. Once the ice arch is formed, the ice boom bears the pressure of upstream ice.

Seasonal storms may overcome the stability of the arch and force large masses of ice against the boom.

The boom was designed to then submerge and allow the ice to override it until the pressure is relieved.

After storm conditions subside, the boom resurfaces and again restrains the ice. Throughout the winter

season, the ice boom facilitates stabilization of the broken ice cover during the refreezing process. In the

spring, it minimizes the severity of ice runs by reducing the quantity of loose ice floes which enter the river.

NYPA intends to construct a new tug vessel to augment and replace existing vessel(s) in their fleet currently

used for the installation, removal, and maintenance of the Lake Erie Ice Boom and various associated

marine construction projects.

Bristol Harbor Group, Inc (BHGI) is a naval architecture and marine engineering firm contracted by NYPA

to develop the contract design documents for the vessel and consult during the bid and construction phases.

BHGI will be assisting NYPA during the bid process and also acting as NYPA’s on-site representative during

the fabrication process, performing quality assurance and certification functions as further described herein.

set forth in 46 CFR 144.205 (American Bureau of Shipping Rules for Building and Classing Steel Vessels

Under 90 meter in Length, hereinafter (ABS SMR or ABS Rules)). The vessel’s machinery, electrical

systems and equipment are intended to comply with the requirements of 46 CFR 143.520 for towing vessels

under 65 feet in length, which imparts specific American Boat and Yacht Council (ABYC) standards to be

applied. In most instances, the contract documents significantly exceed the ABYC requirements

incorporated by reference into Subchapter M, and more closely follow ABS Rule requirements, where

applicable for the vessels’ intended service and route.

The Contractor shall comply with the most restrictive of the contract documents or ABS SMR in terms of

structural and welding standards, and in accordance with the most restrictive of the contract documents,

ABYC standards, or applicable ABS Rule requirements in terms of machinery and electrical systems.

Asbestos or asbestos-containing materials shall not be installed on the vessel or used during the fabrication

of the vessel. Paint shall be lead-free, and with the exception of batteries, lead or lead-containing materials

shall not be installed or used in the fabrication of the vessel.




125 Quality Control/Compliance Verification of compliance with the design standards listed in Subchapter M is intended to be accomplished

in accordance with 46 CFR 144.230 by Professional Engineer (PE) verification of construction and

arrangement standards that are suitable for the vessel’s service and route.

BHGI has developed the contract documents under PE direction and stamped the Contract Drawings

accordingly. The Contractor will be required to provide written verification that the vessel was built according

to the plans, provide a copy of the vessel plans to the local OCMI, and address inspection deficiencies if

and when they arise.

BHGI will assist the Contractor in completing the Application for Inspection of US Vessel (form CG3752) to

initiate inspections to obtain a Certificate of Inspection (COI), as necessary [specifically, certification in

accordance with 136.210 (b)(2)]. Periodic inspections will be conducted by the USCG local OCMI during

construction in order to obtain the COI.

During the detailed design and fabrication process, BHGI and NYPA will perform periodic inspections of

the construction process and review Contractor drawings, calculations, and specifications to ensure the

plans and vessel remain in compliance with the plans and various design standards. BHGI and NYPA will

attempt to coordinate inspection periods with those of the local OCMI. The frequency and duration of

inspections will vary with the stage of construction and extent of progress, but the Contractor shall anticipate

inspections will occur on approximately a bi-weekly schedule.

Welders shall be qualified per the ABS Rules for Materials and Welding (Part 2/4-3) requirements, via

performance qualification tests of the American Bureau of Shipping (ABS), American Welding Society

(AWS), or those of the United States Coast Guard, applicable to the component(s), type(s) and position(s)

of welding to be undertaken. Welding consumables, weld procedures and welder qualifications shall be in

accordance with ABS Rules for Materials and Welding (Part 2). Welder certifications shall be furnished to

NYPA prior to keel laying.

All main butts, seams, and primary shell and internal welds shall be 100% visually inspected (VT) by the

Contractor, the USCG inspector, and BHGI. Contractor shall perform supplementary non-destructive testing

(NDT) for any questionable welds identified via visual inspection at the discretion of the inspector or BHGI,

utilizing a certified third-party NDT firm (minimum level II certification per ASNT Recommended Practice

SNT-TC-1A, Personnel Qualification and Certification in Nondestructive Testing). Contractor shall provide

for magnetic particle (MT) or dye penetrant (PT) testing on a random 10% sampling of shell seams, butts,

and fillets near midships, or other irregular, limited access, or difficult welds to detect surface defects. An

additional 3% of midships seams and butts, and a representative 3% of the rabbet, chines, and shell joints

forward of frame 13 where subjected to ice impact shall be subjected to ultrasonic (UT) or radiographic

testing (RT) to inspect for defects through the full weld thickness. Inspections and tests shall also include

the following highly stressed welds: tow bitt, mooring rings, mooring fittings, and davit foundation. Defective

welds will be rejected and require gouging and re-welding or crop and renewal, where necessary, to correct.

The extent of additional NDT may be expanded based on the extent of slag inclusions, porosity, incomplete

fusion, or any other defects detected. Safety tie-down welds shall undergo 100% VT and MT inspection;

any defects found shall be corrected to the satisfaction of NYPA. Oil-tight and watertight joints will be

subjected to leak testing in accordance with SMR 3-7-1, at the discretion of the inspector or BHGI as to

locations and extents. Contractor is responsible for oil-tight and watertight integrity of all such welds,




regardless of non-destructive tests and inspections, as evidenced by satisfactory hydrostatic test and/or

leak testing to the satisfaction of the USCG inspector.

The USCG and BHGI inspections will also consist of examination of structure, pressure vessels, piping,

main and auxiliary machinery, electrical installations, lifesaving appliances, and fire detection and

extinguishing systems. Contractor shall satisfactorily test and operate all systems while dockside and shall

also conduct extended sea trials to test all systems’ underway functionality, maneuvering capability and

machinery alarms and monitoring systems. Sea trials shall include emergency stop tests, astern running

conditions, a full power endurance run, steering gear testing and turning circle tests. Contractor shall

engage technical support personnel from the engine manufacturer and other subcontractors and equipment

suppliers as necessary, for testing, troubleshooting, and warranty authorization purposes. Oil samples shall

be drawn from the main machinery and submitted for oil analysis upon completion of sea trials. All other

main machinery warranty criteria shall be fulfilled by the Contractor and documentation provided to NYPA.

Workmanship will be closely monitored and any quality issues noted by NYPA, their vendors, or

representatives in the course of the work shall be resolved immediately to the satisfaction of NYPA prior to

the continuation of associated work. Electrical cable installations and terminations shall be neat, well

organized, adequately secured and labeled. Cable penetrations through water- or weathertight boundaries

shall be appropriately sealed; penetrations of interior linings, sheathing, and insulation shall be trimmed

out, covered via the fixture or suitable cover plate, or otherwise concealed from view to maintain a ship-

shape aesthetic. Piping shall be neat, suitably welded where applicable, leak-free, orderly, accurately fit-up

and direct as possible while maintaining straight and true longitudinal, transverse, and vertical runs. All

structural work, application of coatings and electrical, piping, and machinery installations shall be clean in

appearance, functional in fit and form and logically routed to provide the safest, least obstructed, and most

accessible arrangements possible. Any sharp or projecting edges, equipment located within walking paths,

overhead obstructions posing possible contact with personnel, uninsulated pipes over 150 degrees F where

contact is likely, and similar hazards shall be corrected, re-positioned, appropriately guarded, insulated, or

otherwise remediated as necessary to prevent injury to the crew or equipment. Any damage to interior

finishes or sheathing, paint, overspray or similar injuries shall be rectified immediately and construction

900 Coatings

General

Paint and Paint Application

The paints employed shall be products of International Marine Coatings (a division of AkzoNobel) and

Mascoat. Each coat of paint shall be compatible with the previous coat it will cover, including preconstruction

primers (including weld through type) that are to be retained in selected locations as part of the final coating

system. All paints shall be low Volatile Organic Compounds (VOC) type per EPA Standards.

An International Paint Technical Service Representative shall be retained by the Contractor to inspect and

approve surface preparation, application equipment, weather and temperature conditions, and any other key

aspects of the coating processes to ensure proper procedures are utilized and warranty requirements are

complied with where applicable. Reports shall be issued for each inspection and a copy provided to NYPA for

review and records.

Contractor shall submit a signed statement by International (or AkzoNobel) that the Contractor or its approved

painting subcontractor is intimately familiar with the materials specified and is equipped and capable of

performing the work required in accordance with the manufacturer’s specific requirements.

In addition, Contractor shall coordinate with NYPA’s independent certified NACE CIP Level II coating inspector

to be onsite during all paint preparation and application processes. Contractor shall coordinate scheduling of

inspector’s site visits to correlate with appropriate stages of surface preparation, pre-paint application, and

post-paint application to facilitate the inspections and tests in a timely order. In no event shall the Contractor

proceed with coating applications without the inspector’s consent accepting the surface preparation, nor shall

finish coat(s) be applied without prior approval of the quality of base coats, and subsequent inspections

scheduled to evaluate the finished coating system.

The NACE inspector will develop specific hold points, inspection and test schedule, and specific test

processes and coordinate with Contractor to facilitate QA of the coating processes. In general, the following

inspections shall be incorporated within the coating inspection procedures, and shall be considered “Hold”

points as per section 125. NACE inspector shall also prepare repair, re-work, and remediation procedures to

properly address any out-of-specification conditions, film thicknesses, etc noted during the inspections.

Prior to Surface Preparation:

• Verify masking of surfaces/equipment from blast media and overspray

• Ensure all pressure tests and NDT testing is satisfactorily completed on welds in areas to be prepped.

• Ensure any weld porosity, spatter, sharp edges, etc requiring additional preparation prior to coating is satisfactorily completed.

• Verify abrasive size/type against substrate and surface profile requirements of associated coatings.

• Verify cleanliness of abrasive media and compressed air.

Monitoring of Surface Preparation:

• Verify ambient conditions and substrate temperature within specifications.

• Spot check of degree of cleanliness, achieved surface profile during blasting

Subsequent to Surface Preparation:

• Inspect for consistent blast profile.




• Verify degree of cleanliness.

• Verify surface anchor profile within specifications.

Prior to Application of prime or holding coat:


• Verify materials (batch numbers, pot life, multi-part mixing ratios, and any special

procedures/conditions, for instance, for the ice coating)

• Inspect and remove flash rust, condensation, moisture, dust, grease, etc on prepared surface.

Subsequent to prime or holding coat:

• Record wet film thickness and confirm uniform coverage.

• Confirm film quality (lack or drips, sags, runs, holidays).

• Monitor ambient conditions and substrate temperature remain within specifications.

Prior to Application of second or subsequent coats:


• Confirm film quality (lack or drips, sags, runs, holidays).

• Confirm inter-coat surface cleanliness (condensation, moisture, contamination) on coated surface.

• Verify minimum/maximum recoat time.

• Check coating cure.

• Record dry film thickness and uniform coverage of each coat.

• Inspect for pinholes/holidays.

Subsequent to final coat application:

• Visual inspection of film quality (sags, runs, drips, holidays, pinholes).

• Cure testing.

• Record dry film thickness and confirm uniform coverage of finish coat.

Post-Cure and corrective action:

• Verify complete cure.

• Record total dry film thickness and uniform coverage of the coating system.

• Perform coating adhesion test.

• Provide written report(s) including remediation procedures if any portion of the inspections reveal out-

of-specification conditions.

• Repeat processes above as necessary if remedial work is conducted.

Any areas determined to have sub-par surface preparation or anchor profile, coatings applied without suitable

supervision or in unfavorable environmental conditions, inadequate film thickness, or presenting similar

deficiencies will be subject to extensive test and inspection, remedial work or may require complete removal

and re-application, at the discretion of NYPA or its representatives.

The following requirements and the paint schedule provide a very brief summary of manufacturer

recommendations. In each case, refer to paint manufacturer and manufacturer’s representative detailed

recommendations/requirements for surface preparation, cleaning, priming, taping, coating application and

dry film thickness, cure and overcoat times, temperature, relative humidity, thinning, and mixing and




additional conditions. Where manufacturer recommendations or requirements are more stringent than the

guidance herein, the manufacturer’s requirements shall take precedence to these requirements.

All paints shall generally be applied by airless spray in an even coat without runs or sags (brush or roller

application may be used for stripe coats and localized touch-up), within the temperature and humidity

limitations imposed by the manufacturer. [Contractor shall note that in addition to typical application

requirements of epoxy coatings, the Intershield 163 Inerta 160 abrasion resistant epoxy has very specific

requirements in terms of method of application, recommendations for overcoating with antifouling, time to

launch, and time to service in ice. Consult with the International for specific requirements and

recommendations beyond those outlined herein. Also refer to Mascoat for specific application requirements

for the thermal insulating coatings.]

Proper provisions shall be taken to control temperature, humidity, etc for coating applications, meeting all

criteria set forth by the product manufacturer for the environmental conditions at the time of application.

Additionally, coatings shall not be applied outdoors during inclement weather or under otherwise

undesirable conditions.

NYPA’s coating inspector shall be present as required to ensure proper preparation, weather and temperature

conditions, and to measure achieved dry film thicknesses per commercially accepted practices, including

SSPC PA-2 standards. (Note that the dry film thicknesses listed herein are the absolute minimum thicknesses

acceptable to NYPA, to be treated with Level 2 coating thickness restrictions of the PA-2 standard. In addition,

in light of the compact size of the vessel and limited surface area coated, the size of sample areas for readings

and evaluation of non-conformance for the ice coating shall be one-half of the typical PA-2 standard section

8.2, and the entire wetted surface shall be gauged. In other words, 5 spots shall be recorded for each 50-

square-foot interval of submerged surface, vice the 100-square-foot interval listed, over the entire hull, as

opposed to randomly selected portions.) Inspector shall select appropriate test procedures and conduct

surface preparation inspections, including visual inspections, profile measurements, soluble salt conductivity

measurements, and coating tests including wet-film and dry-film thickness measurements, pinhole and

holiday detection, and adhesion tests, as applicable.

Paint and other coating materials shall not be thinned with solvent, nor altered in any manner by the Contractor

unless approved by the manufacturer's representatives. Cure accelerator or similar fast cure

additives/processes shall not be used.

Successive coating applications shall generally be of noticeably different colors in order to aid the inspection

process.

Main deck working area shall be coated with "non-skid" type coatings, or shall be finished by other means

which will result in a substantially higher coefficient of friction for those surfaces as compared to adjacent

surfaces not so treated.

Protection from Overspray

Anodes of cathodic protection systems shall be installed after coatings have been applied. The shell in way

of keel and bilge blocks shall be protected from components in the wood blocking by means of aluminum foil

or an alternate protection of oiled paper or vinyl sheets. Upon written agreement by the coating's

manufacturer, other alternatives may be employed which will result in an acceptable bottom coating.




When blasting and cleaning is performed, the Builder shall seal and prevent damage to neighboring

equipment and intact coatings, by abrasive grains or dross. Similar protection shall be provided to fixtures,

windows, electrical and mechanical equipment etcetera and adjacent coatings during painting. All overspray,

drippings, or smudges shall be removed. No abrasive blasting is to be executed in the neighborhood of wet

paint. Blast abrasives shall be of such a configuration as to create a surface profile in accordance with the

coating manufacturer's recommendations. Abrasives shall be clean, dry, and free of any material likely to

stimulate corrosion of the steel to be blasted.

Repair of Damaged Coatings

Where not otherwise stated, all structural and non-structural parts, piping, and spaces, fittings, and vendor-

supplied items which are normally painted shall, after proper surface preparation, be painted to conform to

the surroundings or to comparable parts or spaces.

When primer and/or finish coatings of structural or non-structural materials and outfit have been damaged

during welding, handling, or installation, due to surface preparation on adjacent surfaces, or corrosion due to

improper application or insufficient application of primer coatings, the suspect areas shall be blasted or power

tool cleaned, and spot or stripe coated with primer and/or finish coats as further described herein.

Where surfaces have been cleaned and primed prior to erection, all welded joints resulting from erection shall

be blasted or power tool cleaned. All painted areas damaged by fabrication, welding, abrasion, or rusting shall

be re-prepared and stripe coated as a maintenance measure as soon as possible after weld inspections

have been successfully conducted and approved and prior to application of finish coats.

Paint shall be applied before rusting of the cleaned surfaces occurs; if abrasive blasted surfaces have rusted due to condensation, rain or similar, re-blasting or sweeping to be carried out.

Damaged galvanized surfaces shall be cleaned and sprayed with zinc metal spray or by using an approved

commercial material.

Pre-Construction Primer

All steel used in the vessels construction shall be cleaned of mill scale and debris to Sa 2 ½ or SSPC 10

standard, and coated with pre-construction primer as follows prior to the start of fabrication, via an automatic

blast and prime facility:

Manufacturer : International

Product : Interplate NQA 937 Zinc Silicate Shop Primer

NQA933 Grey/NQA936 Curing Agent

Zinc Silicate weldable pre-construction primer 2.3 mils wet (0.5 mils dft)

Coating damage to the pre-construction primer is anticipated at all welded connections at the panel,

subassembly, and module stages. In the interests of optimal access for preparation and painting, it is

recommended that a primer stripe coat of Intershield 300V and one sprayed coat be applied to internal

surfaces while the structure is in the subassembly stage and access to all internal surfaces is readily available.

Upon erection of subassemblies into modules and completion of inspections and tests, the erection seams

shall be cleaned and stripe coated to prevent corrosion during major block erection. Upon completion of joining

major blocks and weld-out of master seams and butts, weld seams and butts shall be tested, cleaned and

stripe coated, followed by the final full coat of internal finish paint in accordance with the paint schedule.




Surface Preparation

Cleaning

Hull structural surfaces shall be free of moisture, dust, salt crystals, fouling, loose paint, cleaning residues

and other impurities or foreign matter before the application of coating materials. Areas contaminated with

oil or grease shall be thoroughly degreased, using a water-soluble dispersant and pressure washed with

fresh water, before painting of surface as per specification.

Solvent clean and pressure wash with fresh water where practical; hand clean and use compressed air to

clear dust and loose particles prior to paint applications where necessary where pre-construction primer is

fully intact and adherent.

Abrasive Blasting and Cleaning

Where abrasive blasting is required herein, it shall be performed per ISO 8501-1, "Preparation of Steel

Substrates Before Application of Paints and Related Products", or the equivalent SSPC standard as follows:

Sa 2 1/2 "Near White" blasting or SSPC SP10 “Near White Blast” to a surface profile > 3 mils

Where power tool cleaning is specified, herein, it shall be as follows:

St 2 Thorough hand and power tool cleaning or SSPC SP2 “Hand Tool Clean”

St 3 Very thorough hand and power tool cleaning or SSPC SP3 “Power Tool Clean”

Where solvent cleaning is specified, it shall be in accordance with:

SSPC SP1 “Solvent cleaning”

Where power tool cleaning to bare metal is specified, it shall be in accordance with:

SSPC SP11 “Power Tool Cleaning to Bare Metal”
