SCOPE OF WORK

Bow Thruster Control, Engineering & Install

1. SCOPE

1.1 Background. The U.S. Coast Guard (USCG) Surface Forces Logistics Center (SFLC) – Long Range Enforcer Product Line (LREPL) has identified the need to upgrade the Bow Thruster Control Panels onboard USCGC HEALY (WAGB-20). The upgrade involves transitioning from legacy analog control panels to modern touchscreen-based human-machine interfaces (HMIs). The Human Systems Integration Division (DPR-23) conducted a human factors review of the proposed HMI design and identified several areas requiring further engineering development to ensure compliance with MIL-STD-1472H and operational requirements.

1.2 Scope. This Statement of Work (SOW) establishes the requirements for the Original Equipment Manufacturer (OEM) OmniThruster Inc., to provide engineering services, supply all necessary parts, and perform the installation of the six Control Stations and Programmable Logic Control (PLC) for the Bow Thruster System onboard the USCGC HEALY (WAGB-20).

1.3 Objective. The objective of this SOW is to engage OmniThruster, Inc. to refine and finalize the design of the Bow Thruster Control HMI upgrade, supply all required components, perform the installation, and ensure compliance with MIL-STD-1472H, alignment with operator needs, and seamless integration into the USCGC HEALY operational environment.
