NOAA Ship OSCAR DYSON MEP - Propulsion System Modernization Requirements

1. INTRODUCTION

The first National Oceanic and Atmospheric Administration (NOAA) Fisheries Survey Vessel (FSV) was commissioned in 2005 and is approaching a midlife extension. The legacy propulsion system is functional but several components are obsolete and require modernization for continued operation and to meet agency environmental goals.

This specification defines the Low Voltage Direct Current (LVDC) propulsion system and requirements for a Single Source Vendor (SSV) in their entirety. Contractors shall provide the submittals as defined by these requirements. Contractors shall reference compliance with this specification in the proposal.

Any questions regarding this specification should be directed to The NOAA FSV Technical Program

Manager.

The services shall be complete in all respects, with components, features, materials suitable for the intended purpose, consistent with the design requirements and NOAA's furnished components defined below. Omission of any necessary component for the listed Vendor Scope of Supply does not relieve the

Contrator of the responsibility to furnish all components needed to meet the requirements herein. The SSV shall reference compliance with this work specification in the proposal.

SECTION 3.2.A Legacy Electrical Plant Configuration

3.2.B TYPICAL FSV REPOWER ENGINE SELECTION

1. Configuration 4: 3x1400-1670KWe (CAT 3512) - Recommended, meets all operational profiles.

• 3-CAT 3512 tier-4 coupled with Siemens Variable Speeds Alternators will offer 2 engine redundancy with a total power output of 4,200-4800KWe. Power command range 75%-100% offers 1x3512 in standby with 2x3512 engines at a maximum predicted load of 94% and daily fuel burn rate ~6,300 gallons-per-day. This combination meets and/or exceeds the desired 4,500KWe compared to the legacy configuration and is considered acceptable. The physical total footprint is smaller compared to the legacy configuration and would reduce tonnage compared to the legacy mechanical tonnage. This also supports the NOAA request for 3 engine configurations.

3.3. Diesel Generator Noise Performance Requirements

3.3.1. The diesel generator sets must be individually compound mounted with intermediate masses designed to behave as a rigid mass up to at least 100 Hz. Four individual masses must be provided for each diesel generator set, with one mass located at each corner of the subbase. The combined weight of the four intermediate masses under each diesel generator set must have a total weight equal to or greater than 0.4 times the weight of the diesel generator set, including subbase.

3.3.2. The first and second stage resilient mounts must be selected such that all mounts are within their maximum rated load limits and the vertical translational resonant frequency of the intermediate masses is equal to, or less than, 12.3 Hz. The Contractor must demonstrate via measurement or Government-approved calculation that the intermediate masses behave as a rigid mass at all frequencies below 100 Hz.

3.3.3. The locations of the mounts on the masses must be such that the resonant pitch and roll frequencies of the intermediate masses do not coincide with any of the exciting diesel generator tones. Four masses minimum for each diesel generator set will be required.

3.3.4. The diesel generator set vibration levels (1 Hz bandwidth) may not exceed those listed in Table 3.3-1. These levels must be measured on the subbase, above the compound mounting system (above mounts) at each corner of the diesel generator sets, operating under load, in accordance with MIL-STD-740-2. A straight-line interpolation between the points listed in Table 3.3-1 must be used to establish vibration levels at intermediate frequencies.

3.3.5. The SSV must perform the required structural acoustics analyses of the diesel generator mounting systems. These analyses must establish the intermediate mass vibration criteria to ensure that the underwater radiated noise requirement is met. These intermediate mass criteria must be provided to the government prior to factory acceptance testing of the diesel generator sets. The contractor must conduct factory acceptance tests (FAT) on all three-diesel generator sets and their compound mounting systems prior to installation in the ship to ensure that both the above mount vibration criteria provided in Table 3.3-1 and the intermediate mass vibration criteria established by the SSV are not exceeded. The intermediate mass system need only be tested on the lead ship’s diesel generator sets. Diesel generator above mount vibration levels must be measured. The diesel generator set FAT measurement results must be provided to the government for review prior to installation of the diesel generator sets in the ship.

• 480VAC Bus-3S and Bus-4S shall be supplied with independent feeds from the 600vac 1S/2S Switchboard via stepdown transformers. Each feed shall be sized to support the full load of both Bus-3S and Bus-4S simultaneously. The feeds shall be configured as such to interlock the bus-tie breaker during typical plant operations. The bus-tie breaker interlock shall only be released if one of the primary 480vac feeds fails. See Image 4.3.3 Typical 480VAC Split Bus configuration.

4.3.9. GCC and Load Center Repower

• As part of the NOAA FSV Repower effort, the Auxiliary Machinery and HVAC equipment prime movers will be converted from 600VAC to 480VAC. This effort impacts a number of Motor Controllers and Load Centers. The power conversion impacts the Voltage Control Transformers in the GCC’s and will require replacement to 480VAC/120VAC. The conversion also requires some isolation breakers and contactors/overloads to be replaced with higher rated equipment.

The following tables outline each GCC and Load Center impacted and notates the corrective actions. Legacy isolation hardware that violates the load requirements are highlighted “RED”

• SSV shall install 2-speed motor contactor and overloads in the existing GCC for the following circuits. The equipment type shall align with the legacy GCC hardware
