Prototype R7 Boom Crane Assembly

SECTION 1.0 – ADMINISTRATIVE INFORMATION

1.1 Introduction

The United States Marine Corps (USMC) is looking to improve the coating system used on the R7 crane installation. The R7 crane installation is on the external of the Assault Amphibious Vehicle (AAV) Recovery Variant (R7) and is staged in a highly corrosive environment. The physical geometry of the primary boom assembly and telescoping boom assembly, makes it extremely difficult to refurbish (i.e. abrasively blast and re-coat). Typically, when the AAV R7 comes in with a corroded crane installation, the standard practice is to remove it, disassemble, identify items that can be salvaged and to produce a new primary boom assembly and telescoping boom assembly. This process adds significant cost to the process and can be substantially reduced if an improved coating system is used on the R7 crane, increasing its service life.

This statement of work will describe the necessary tasks required to provide one prototype boom assembly, in accordance with drawing 7010547, with the exception of changes made as described in Section 1.3.

1.2 Government Furnished Equipment (GFE)

As a part of this effort, the selected vendor will be provided the following government furnished equipment (GFE), as Federal Condition Code D (Serviceable/Test Modification). The description of federal condition codes is found in the referenced document under section 6.0. The selected vendor shall provide all other items required to perform the necessary work and deliver the boom assembly

(DWG 7010547).
