Niagara Supervisor in Building 374 (ECC).

2. NETWORK ADDRESSING

2.1. IP

2.1.1. All IP addresses on the ICS network shall be provided by NAVFAC. Submit request for all IP devices to contracting officer.

2.1.2. All IP devices shall be networked to allow IP communication directly from Building 374 ECC.

2.2. BACNET

2.2.1. All BACnet instances and network numbers shall be provided by NAVFAC. Submit request for all BACnet addressing information to contracting officer.

3. POINT AND OBJECT CONFIGURATION

3.1. POINT AND EQUIPMENT NAMING

3.1.1. Assign all points on the ICS network a name from the naming convention list. The point description should match the intended operation of the ICS point being named.

Intermediate logic points used for calculations within the JACE do not need a standard name. The point containing the final result of the logic should be standard however. See

Appendix 6.1 and 6.2 for point and equipment list.

3.1.2. In the event that no applicable point name exists for an ICS point, the contractor shall use the following guidelines to create a new point name:

3.1.2.1. Contractor shall RFI point names recommendations for any points that do not seem to fit into the naming convention.

3.1.2.2. No special characters including spaces, hyphens and periods shall be used. See section

3.6 SPECIAL CHARACTERS.

3.1.2.3. Use CamelCase instead of spaces in point names.

3.1.2.4. In some circumstances, certain equipment and station names may use underscores instead of spaces with NAVFAC PWD-Maine HVAC Action Team approval.

3.1.2.5. If there are multiple points for a piece of equipment that require the same point name prefix the point name with a brief descriptor such as “North”. The point will become

“NorthZoneTemp”. If there are multiple NorthZoneTemp points in a single point folder they shall be numbered like: “NorthZoneTemp2”.

3.1.3. Multiple pieces of equipment under one controller shall use folders to separate the different pieces of equipment into logical devices. This will allow the use of the normal naming convention rules as well as graphic templates, history naming etc.

3.3.4. BUILDING NUMBERS

20180717 - NAVFAC MIDLANT PWD-Maine – ICS Standard 5

3.3.4.1. All buildings shall use a 3 digit number keeping leading zeroes. Since there are minimal dry dock numbers they shall use 2 digits.

3.3.5. No spaces shall be used. Use an underscore (_) between the location and building prefix.

3.3.6. If there are multiple buildings served by one JACE, the station shall indicate this by listing the buildings separated by underscores.

3.3.7. STATION NAME EXAMPLES

PNSY_B043

PNSY_B153_B170_B170A

PNSY_DD01

CUTLER_B001

3.4. ALARMS

3.4.1. EXTENSION CONFIGURATION

3.4.1.1. SOURCE NAME

3.4.1.1.1. Utilize bformat so the when viewed in the alarm console, the alarm is annunciated with a source name similar to the last part of the history names.

For example:

VAV01_ZoneTemp

HotWaterSystem_PriHWSupplyTemp

3.4.1.1.2. This allows the operator to understand what system and what point is in alarm.

3.4.1.2. MESSAGE TEXT

3.4.1.2.1. The message text shall include some basics about the alarm. This can be generic based on the type of alarm the extension it is.

3.4.2. ALARM CLASSES

3.4.2.1. The three alarm classes that are to be used are:

3.4.2.1.1. Notification. Designated for non-critical alarms.

3.4.2.1.2. System. Designated for system-type alarms such as controllers offline (if not deemed critical).

3.4.2.1.3. Critical. Designated for alarms for anything that was thought to be of critical nature.

3.4.2.2. In the supervisor station, the alarm classes are brought into the station and appended with the JACE station prefix. This allows the supervisor station to organize the alarm consoles by both by the different alarm classes and by the buildings. The building name in the supervisor alarm class is what determines what building the alarm is coming from. This prefix is required since the alarm name will only display the equipment name with no building designation.

3.5. HISTORIES

3.5.1. NAMING

3.5.1.1. Name shall be in the format: “[BUILDING PREFIX][BUILDING NUMBER]_[EQUIPMENT

TYPE][EQUIPMENT INSTANCE]_[POINT NAME]”.

3.5.1.2. BUILDING PREFIX EXAMPLES

“B” (Building)

“H” (Housing)

20180717 - NAVFAC MIDLANT PWD-Maine – ICS Standard 6

“DD” (Dry Dock)

“NOSC” (Naval Operation Support Center)

3.5.1.3. BUILDING NUMBER

3.5.1.3.1. All buildings shall use a 3 digit number keeping leading zeroes. Since there are minimal dry dock numbers they shall use 2 digits.

3.5.1.4. EQUIPMENT TYPE

3.5.1.4.1. As listed in the Point and Equipment Naming Convention List.

3.5.1.5. EQUIPMENT INSTANCE

3.5.1.5.1. The number (or letter) used to uniquely identify the piece of equipment

3.5.1.6. POINT NAME

3.5.1.6.1. Shall be the same as the parent object.

3.5.1.6.2. No spaces shall be used. Use an underscore (_) building number and equipment type and also between equipment instance and point name.

3.5.1.7. HISTORY NAMING EXAMPLES

B153_HotWaterSystem_PriHWSupplyTemp

B156_JACE_Module1_OutsideAirTemp

B170A_ARU01_ReturnAirTemp

B059_VAV05_BoxFlow

DD01_DH01_ZoneTemp

3.5.1.8. The history names should be the same under both the JACE and as imported into the

Niagara Supervisor.

3.5.2. EXTENSION CONFIGURATION

3.5.2.1. History extensions shall reside within the JACE. The history shall be setup to import its data at least once every 24 hours.

3.5.2.2. Numeric points shall use interval trends set at 10 minutes. Boolean and Enumerated histories shall be set for Change of Value (COV).

3.6. SPECIAL CHARACTERS

3.6.1. The Niagara framework does not allow certain characters to be used in naming objects. If illegal characters are used, Niagara will use an escape sequence to replace the illegal character. An example is that the hyphen would be replaced with “$2d”. Although the display name of the object will show the hyphen, the ord of the object will contain the $2d.

The history name will also contain $2d which makes browsing through the history points list more difficult for an operator. The extra characters also count towards the history name maximum character count. Approved characters are A-Z, 0-9, and underscore (_).

4. GRAPHICAL USER INTERFACE

4.1. Graphics shall maintain the same look and feel as existing ICS graphics. See Appendix 6.3 for graphic user interface examples.

4.2. Graphics shall use standard pallets and should not require any special licenses to use.

4.3. EXPORT TAGS

4.3.1. Niagara export tag architecture shall be used.

4.3.2. Graphics shall be created in the building’s supervisor controller and then exported through the join process into the existing Niagara server in Building 374 (ECC).

20180717 - NAVFAC MIDLANT PWD-Maine – ICS Standard 7

4.3.3. The intent is to give a technician complete local access to the building graphics while the technician in troubleshooting from inside the building. The local building graphics would also be programmatically replicated in the Niagara Supervisor in Building 374 (ECC).

4.3.4. The Join process shall only be initiated after approval from NAVFAC PWD-Maine ICS System

Admin.

5. USER ACCESS

5.1. EXISTING INSTALLATIONS

5.1.1. A contractor performing new work on an existing JACE or the Niagara Supervisor shall have a temporary user created for them to use. Usernames will be assigned uniquely per individual. No group names or sharing of names is allowed. Coordinate users with NAVFAC

PWD-Maine ICS System Admin.

5.2. NEW INSTALLATIONS

5.2.1. Any new JACE installation shall be setup similar to the other JACEs installed on the ICS network.

5.2.2. The Admin superuser, all platform users, and the passphrase shall be turned over before the system can be turned over to the government.

5.2.3. Credentials shall be given to the contracting official of the project on CD.

5.2.4. The JACE shall be setup to receive network users from the Niagara Supervisor in Building

374. Coordinate user roles and prototypes with NAVFAC PWD-Maine ICS System Admin.

Join profile shall be setup. A pre-configured join profile is available upon request.

5.2.5. The station Admin superuser will not be a network user and shall be left in the JACE.

Considerations

Introduction:

This electrical standard has been prepared to promote consistency in design and construction, and to establish preferred wiring methods and materials used in electrical installations. The intent is to not reproduce the content of the various codes and standards that apply to Navy electrical installations.

However, areas that have been identified as recurring issues in the design and construction of electrical systems have been included to avoid further confusion, and to eliminate the appearance of arbitrary decisions that can compound frustration to both the Navy and contractors in the execution of various contracts.

This document is not intended to contradict the requirements of the various UFCs, industry standards and codes governing the installation of efficient, cost effective, and safe electrical installations. With few exceptions, all the requirements indicated herein are in compliance with those various codes and standards. The electrical systems on the Portsmouth Naval Shipyard have evolved over many decades and under the supervision of many fine engineers, technicians and electricians from the past. To the greatest extent possible, this document attempts to respect the design rationale which resulted in the present state of the electrical distribution on the shipyard.

This is a living document which will be subject to periodic revisions. Changes are not meant to constrain, confuse, or trap contractors and engineers who perform the vital work on the shipyard electrical systems. This document is meant to level the playing field for all stake holders as well as respond to situations and changing conditions in the electrical industry. As with other such documents, engineers and contractors will not be held responsible for retroactive corrections due to new requirements and revisions to this standard as long as contract requirements are met for prior work.

Medium Voltage

Considerations:

o Nominal distribution voltage is 13.2 kV, resistance grounded, wye.

o Conductors shall be MV‐105, shielded, EPR insulation, 15kV class.

4/0 AWG for radials.

500 kcmil for loops.

Conductors and shields, Copper.

o Splices shall be 15kV class, hot shrink type suitable for wet location (Submerged).

o Terminations shall be 15kV class, 600 Amp, dead break type elbows for radials.

o Terminations shall be 15kV class, 600 Amp, dead break type elbows for loops.

o Standards & Specifications:

UFC 3‐550‐01

UFGS 33 71 02

IEEE C62.22

Low Voltage

Considerations:

o Low voltage distribution on PNSY is derived from a grounded, wye system from distribution Load Centers throughout the ship yard. Utilization voltage is 480 VAC.

The Load Centers are set up as double ended, separately derived systems with no ability to switch the neutral conductors. As such, PNSY does not allow pulling neutrals in feeders supplying facilities at PNSY.

480/277 systems are not allowed unless the neutral is locally derived at the load end of the facility feeder via isolation transformers.

Design calculations shall be provided for all new feeders used to supply existing and new facilities. No feeder will be approved for connection without the prior approval of the CI Electrical Branch and the UEM.

o Exterior Low Voltage Distribution Feeders Supplying PNSY Facilities:

UFC 3‐550‐01

UFGS 33 71 02

o Ground Resistance Testing: Due to the logistics of driving test rods, potential subterranean obstacles, congested, and over utilized real estate, use of the Fall‐of‐

Potential method for measuring earth ground resistance is impractical. Contractors and designers shall consult with the PWD ME Electrical Engineering Branch to coordinate alternate test methods.

o Feeder Calculations: Significant additions or loads added to existing infrastructure shall be preceded by a load study of the affected source—(service entrance, sub‐panel, etc.)—prior to commencement of design and construction. The method used shall comply with NFPA 70, Art 220. (See Appendix A: Determining Existing Loads.)

The designer of record shall be responsible for determining the suitability of any proposed electrical source for any new loads served under any given project.

30 amps or greater @ 480, 30 amps or greater @ 208 for service and feeder calculations.

The designer of record shall provide short circuit calculations for any equipment and current interrupting device added to any facility or electrical system.

Coordinate calculation method with PWD ME Electrical Engineering Branch.

Electrical connections derived from double ended sources may be calculated based on infinite bus at the line end of a feeder or service.

Minimum KAIC rating shall be 10kA.

o Multi‐wire branch circuits should be avoided.

In the event that multi‐wire branch circuits are necessary (i.e., systems furniture) all ungrounded conductors shall be switched simultaneously by the branch circuit disconnecting means.

APPENDIX A: DETERMINING EXISTING LOADS

In order to ensure that sufficient capacity is available on any feeder or service that any person, project, code, or entity wants to add additional load onto, the following policy shall apply. This will include any load center, switchboard, panelboard, or other device that is used to distribute electrical power.

Background:

NFPA 70, Art 220.87 Determining Existing Loads. The calculation of a feeder or service load for existing installations shall be permitted to use actual maximum demand to determine the existing load under all of the following conditions:

1) The maximum demand data is available for a 1‐year period.

2) The maximum demand at 125 percent plus the new load does not exceed the ampacity of the feeder or rating of the service.

3) The feeder has overcurrent protection in accordance with 240.4, and the service has overload protection in accordance with 230.90.

In the absence of maximum demand data as indicated in sub‐paragraph 1), the following exception shall apply.

Exception: If the maximum demand data for a 1‐year period is not available, the calculated load shall be permitted to be based on the maximum demand (the highest average kilowatts reached and maintained for a 15‐minute interval) continuously recorded over a minimum 30‐day period using a recording ammeter or power meter connected to the highest loaded phase of the feeder or service, based on the initial loading at the start of the recording. The recording shall reflect the maximum demand of the feeder or service by being taken when the building or space is occupied and shall include by measurement or calculation the larger of the heating or cooling equipment load, and other loads that may be periodic in nature due to seasonal, operational or similar conditions.

For the purpose of this policy, demand shall be defined as follows:

The electric load at the receiving terminals averaged over a 15‐minute interval.

Qualifications:

All PWD ME, CI electrical engineers and electrical engineering technicians shall fully understand and be able to apply this policy and its procedures.

All PWD ME, CI electrical engineers and electrical engineering technicians shall demonstrate a comprehensive knowledge of all the instruments used in the collection of data, and diagnostic software associated with the processing of instrument data.

Procedure:

Installing and removing the test equipment required to conduct the demand study is an invasive process that may require at least 2 outages in many cases. Outages are an inconvenience to the tenants served by the equipment that will be disturbed throughout the test. The engineer should make every attempt to collect the data without the need for conducting outages. For instance, at remote sites like Prospect

Harbor, billing information can be sought that will cover the preferred 1‐year period indicated above.

It will be the engineer’s or AE’s responsibility to collect required data or…
