3.0 NOTES

3.1 DOMESTIC MAKE - Domestic make refers to equipment available from United States (U.S.) manufacturers.

3.2 SHORT TONS - Loads, where specified in tons, are in short tons (1 short ton = 2000 lbs)

3.3 ENGLISH DOCUMENTATION - All documentation and equipment

identification shall be provided in the English language.

4.0 PURPOSE - The purpose of this specification is to define the requirements for a transport system, intended to be used in a naval shipyard for removal and reinstallation of various large complex components and assemblies. This specification shall be used as a guideline in developing the final purchasing proposals.

4.1 PRIMARY USE OF TRANSPORTERS - The primary use for this transporter system will be to lift and carry various large complex components and assemblies. At the shipyard facility, the unloaded transporters will be lifted by crane and lowered onto the floor of a graving dock. Once located in the graving dock, the transport system will be used to lift, move and precisely position the components during removal and reinstallation operations. During these operations, the major assemblies must be accurately positioned collinear to each other and to the ship’s axis.

5.0 PERFORMANCE REQUIREMENTS

5.1 GENERAL - Each transporter will work as a part of a system of transporters to assist with the assembly, installation, and removal of various large complex components and assemblies into and out of U.S. Navy vessels in a naval shipyard. Individual transporters shall have the capability to precisely and accurately lift, transport and control a load within the parameters stipulated in Section 6. Each transporter will possess a high degree of maneuverability, whether being used independently or concurrently with other transporters. When operating concurrently, multiple transporters will be controlled by one operator, using one controller. Whether being operated independently or concurrently, each transporter will have the ability to independently and automatically control a load’s position by adjusting to variations in the surface over which it rolls, while imparting low contact pressures to those underlying surfaces. The unit performance will meet all other design parameters stipulated herein.

Transporters procured under this specification will utilize the original design, approved by Electric Boat under contract PPU246-064 (2009). All new additions to the vehicles based on upgrades or new requirements in this specification will be verified by design review, engineering analysis or verification during testing.

All original vehicle characteristics and requirements are assumed to be acceptable based on Electric Boat’s acceptance of the original design.

Additionally it is understood that the vehicles specified herein must only be compatible with the vehicles located at Portsmouth Naval Shipyard, not at Pearl Harbor Naval Shipyard

5.2 USAGE FOR HANDLING SUBASSEMBLIES - The transport system shall:

a) Interface with exisiting shipyard lifting strongsbacks areas (Figure 2) by fitting under the strongbacks, and reacting at the current strongback load support areas.

b) Support the combined weight of the various components and the specialized lifting fixtures

c) While loaded, the transport system shall be capable of aligning the axis of components both co-linear to each other and to the main aixs of the ship.

d) Provide motive power to move components and subassemblies within the drydock at a slow controlled speed, while being able to fine-adjust a loaded transporter’s position parallel to the ship’s axis, vertically, and athwartship.

5.2.1 SECTIONS –

5.2.2 LOAD SUPPORT AREAS – The load support areas are under the four short, main, fore-aft beams of the strongbacks. There are four load support areas per strongback and two strongbacks per section (see Figures 2 & 3), resulting in eight load support areas per section. The main axis of the strongbacks shall be oriented in the same direction as the main axis of the transporter.

NOTE: Figures 2 & 3 are excerpted from EB DWG H902-1021 REV B. This drawing may be consulted for actual dimensions.

Figure 2 – 21’ Strongback

Figure 3 – 24’ Strongback

5.2.3 INTERCHANGEABILITY - All transporters shall have the capability to operate as a master or slave to any other transporter during concurrent operations. This shall include transporters currently owned and operated by Portsmouth Naval Shipyard. Any and all work required to achieve compatibility with existing machines shall be identified by the vendor, approved in writing by the Government, and performed by the vendor during the execution of this contract. Verification of concurrent mode operation will be demonstrated during Factory Acceptance Testing using two and three vehicles.. Demonstration of compatibility with the four existing transporters will be performed on-site after delivery during the Site Acceptance Test. Prior to this test, the existing vehicles will be made available to the contractor for software configuration to allow them to recognize the new vehicles.

5.2.4 CONCURRENT OPERATION – Multiple transporters will be ganged to operate together during component removal and installation. The transporter system furnished under this specification shall include all controls, indication, systems connections, etc., required so that two or more ganged transporters can be operated by a single operator using a single control unit. The vehicles shall communicate via a cabled connection identical to the existing vehicles. In addition to communication for motion control, E-Stop communication is required when transporters are being operated in a 2(or 3)+1 configuration (two or three transporters operated concurrently by one operator, and a separate transporter operated by a second operator, such that depressing the E-Stop on any transporter will shut down all transporters). Each transporter unit shall be provided with sufficient interconnecting cabling to accommodate up to fifty (50) foot spacing between the transporters.

5.2.4.1 RELATIVE POSITION - For concurrent operations, all transporters must have the capability to maintain their relative position to an accuracy of +/- 0.75” when traveling longitudinally in creep mode and +/- 0.38” when traveling transversely in creep mode without the addition of a structural link between the transporters. The vendor shall provide a permanently marked reflector or target with graduations to allow an operator to determine vehicle relative position while in concurrent operation.

5.2.4.2 OVERTORQUE LIMITATION - When the transport system is operating in a concurrent operation mode, the system shall have overtorque limiting features to prevent drive axle and gear reducer windup in either direction.

5.2.4.3 INTERCHANGEABILITY / CONCURRENT OPERATION - Each/all

transporter(s) shall have the capability to operate as a master or slave to any other transporter during concurrent operations. This shall include existing transporters owned by the Shipyards.

5.3 QUANTITIES – This specification is for three transporter.

5.4 PHYSICAL CHARACTERISTICS - The following physical characteristics of the transport system may not be deviated from. Prior to any change in these areas the Contractor shall submit the proposed change to the Government, in writing, for Government’s written approval.

a) Transporter overall minimum/maximum envelope as shown in Figure 4.

b) Transporter, in the fully lowered position, unloaded, no higher than 27 inches. See Figure 4.

c) Transporter, in the fully raised position, unloaded, no less than 37 inches. See Figure 4.
