The barges to be of a complete design that meets the criteria listed below.

The design shall include structural analysis and stability analysis considering equipment loading and barges pinned together during operations.

The Contractor shall submit drawings and calculations to the Government for review and approval.

3.2.2 The barges will be approximately 36 feet wide and 75 feet long. The barges shall be designed to be truckable to Halcomb’s Landing, Jamestown, KY.

3.2.2.1 The final dimensions of the barges are dependent on the contractor’s stability analysis that considers moment forces from a material handling grapple on a 46-50 feet long telescoping boom picking up 2,000 lbs. of material at full reach, as well as placement and weight of tool room, engine room and engines, fuel tanks, deckhouse, woodchipper, dumpster, and a skid steer. If these arrangements fail to be determined by calculation or modeling, the contractor may propose alternate barge dimensions.

3.3.1 The starboard barge, as viewed from the push boat, should have in-hull power unit, 100-gallon fuel tank, hydraulic tank with oil cooler (sized per knuckle boom specifications 30-50 gallons approximately), power unit stairway access, and tool room. The starboard barge should also have the knuckle boom mounted on the starboard bow, 8 –approximately 10ft from the bow and sides.

3.3.4 The port barge, as viewed from the push boat, shall incorporate a 1200-gallon fuel tank to supply fuel for the generator. It shall also have a fuel transfer pump connected to a 75ft hose reel on the deck. It shall also have a ramp on the bow that measures 14 feet by 14 feet, operated by two self-contained hydraulicsufficiently powered winch systems. It should also have a climate-controlled deckhouse with a type II Marine sanitation system for the head.

3.3.5 The barges below the deckhouse and tool room will be of an open hull design, if possible.

3.3.6 The two (2) spuds, (one forward on the port barge, and one aft of the chipper working area, and within reach of the knuckle boom on the starboard barge) should be of a design that allows free rotation of the knuckle boom. This could include a piecewise design, telescoping, and/or with mechanical drives.

3.3.7 Port barge spud shall be 20 feet long (minimum). Starboard barge spud shall be 25 feet long (minimum). During the kick-off meetingquestion period, the AE shall discusscan suggest with LRN/LC the feasibility of incorporating/designing longer spuds and their position to accommodate mission requirement.
