PERFORMANCE WORK STATEMENT (PWS)

FOR

REPLACEMENT GOVERNOR SYSTEM ON THE ISOTTA FRASCHINI MOTORI

MODEL V1312T1-MLH-KC MAIN PROPULSION DIESEL ENGINES

1.0 GENERAL

1.1 Background/Scope

The governor actuators installed on the Isotta Fraschini Motori (IFM) Model V1312T1- MLH-KC Main Propulsion Diesel Engines for the USCG inland construction tenders and river tenders have experienced premature failures due to excessive shipboard and engine vibrations. The U.S. Coast Guard Surface Forces Logistics Center – Icebreaker, Buoy, and Construction Tender Product Line (SFLC-IBCTPL) requires support in identifying replacement options and prototyping a replacement governor system on three cutters (one cutter of each subclass). This will result in six (6) prototype installations, two engines for each cutter. Contingent on successful prototype efforts, support may include installation of the approved replacement governor system for the remaining MPDEs in the fleet.

The current configuration consists of the following components, with the governor actuator directly connected to the engine’s fuel injection pump.

• Heinzman Helenos II - Digital Control Unit Model DC 20402-01

• Heinzman Actuator Model StG 2040-01

• Bosch Inline Fuel Injection Pump - Model “PES 12P120 A920 RS”

• Isotta Fraschini Model V1312T1-MLH-KC Main Propulsion Diesel Engine (MPDE)

1.2 Objectives

The Contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to analyze, identify, install, test, and support the replacement governor system on the USCG IFM Model V1312T1-MLH-KC MPDEs. The proposed system shall be capable of withstanding the current levels of vibration present through the operating range of the MPDE. Tasking shall include the following support as defined within this PWS:

• Participate in a Post Award Conference (PWS 4.3)

• Conduct familiarization site-visits (3 total) to review “as-built” system and component configuration, including data collection & analysis of current vibration levels experienced by the actuator (PWS 2.1, 2.2, & 2.3)

• Conduct research to identify commercial options and propose suitable replacement governor system(s) for USCG review/approval (PWS 2.4)

• Install prototype governor system onboard three (3) USCG cutters (PWS 2.5)

• Provide on-site and remote technical support for the prototype installations for the duration of the prototype period (PWS 2.5)

• Conduct data collection & vibration analysis of the prototyped systems, including analysis/comparisons between existing and prototyped governor systems (PWS 2.6)

• Contingent on successful prototype efforts and USCG acceptance, install the approved replacement system on the remaining cutters in the fleet; 21 cutters, 42 MPDEs total (PWS 2.7)
