STATEMENT OF WORK (SOW)

FOR

USCGC HICKORY Thruster SB Repairs and replacement of Yokogawa Transducer System, AEM 2020

CGC HICKORY requires repairs or replacement of their Yokogawa Transducer to their monitoring and control system for the Bow & Stern Thruster System. The local gauges are currently not reading correctly, and the crew has determined it is due to the failed transducers installed. They are no longer supported and need to be replaced. Their bow and stern thrusters and still have a reliability issue and an immediate need for technical support for tasks outlined in this Statement of Work (SOW).

1.0 GENERAL

1.1 BACKGROUND

The 225’ WLB asset, USCGC HICKORY, is experiencing voltage and amperage fluctuations on their bow and stern thruster around 60-70% load due to an unknown reason leading to premature thruster shutdowns. One of the outstanding discrepancies on their thruster system is that their analog and multi select gauges are providing differing readings than expected from other monitoring system. SFLC is requesting technical oversite and documentation of necessary changes to implement new hardware and programming changes to return the monitoring systems to fully mission capable. The thruster system requires on-site technical support to field and test these repairs and programming changes.

1.2 SCOPE

The scope of this contract is defined by the efforts and tools required to support USCGC HICKORY (WLB 212). The Contractor shall provide all labor, materials, and tools necessary to install the AEM 2020 and ensure the local gauges and monitoring system for the thruster system is operating effectively and readouts match what can be viewed either on MPCMS or via Fluke meters.

1.3 OBJECTIVE

The goal is to successfully implement changes and test pier side and to ensure the new hardware corrects the existing discrepancy on the local monitoring system and see if this is impacting the overall performance of the system.

1.4 APPLICABLE DOCUMENTS

1.4.1 Compliance Documents

The following documents provide specifications, standards, or guidelines that must be complied with in order to meet the requirements of this contract:

Coast Guard Technical Publication 3556, SWBS 568, Section F, DC Motor Drive Unit Coast Guard Drawing 225-WLM-437-009, Rev C, Thruster Control Sys

2.1 Yokogawa Watt Transducer & Replacement to AEM 2020

The Contractor shall perform any inspections, evaluations, tests, and/or tuning, as deemed necessary, to determine the most effective mounting and wire runs to remove old transducers and replace with the AEM 2020. The contractor will troubleshoot and adjust parameters for the programming changes required to ensure readout to the DECS-250 voltage regulator is effective to minimize adverse impact to the operability of the thruster drives while improving reliability of the thrusters and thruster monitoring system

2.1.1 Upon completion of the install of the AEM 2020 hardware, CTR must provide documentation on one line drawings provided by USCG to ensure configuration changes are documented. These changes must be documented with photos or hand sketches showing dimensions and layout as well.

2.1.2 CTR must all provide bill of materials used during the install, cables used, mounting hardware, meter names, and any other physical objects introduced into the cabinet

2.1.3 Contractor must have a representative on site to validate the inputs to the DECS- 250 voltage regulator and provide any necessary software updates or set point changes needed to continue operation with the new transducer

2.1.4 CTR must provide input of any necessary changes to upstream equipment that needs to be upgraded for system compatibility

2.1.5 CTR must provide elementary wiring diagram changes

2.1.6 CCT must perform pier side testing and provide test results for USCG to review

2.1.7 CTR will provide DATA sheets, techmanuals, or location of said documents for release to the USCG to maintain records

2.2 Test Thoroughly and Document

The Contractor shall ensure the system is fully functional by preforming a system operational test to be witnessed by Engineer Officer (EO) or the EO’s designated representative.

2.2.1 The Contractor shall provide a trip report documenting all findings no later than 48 hours after returning to the home office.
