7.2 APPROACH:

7.2.1 The ship shall be afforded an unobstructed approach to the Contractor’s facility (plant); including rented, leased, subcontracted facilities, or the facilities of any subcontractor where the vessel will be berthed and moored, for any part of the performance period. There must be no danger of the ship grounding, or colliding with all overhead obstructions during transit. This applies for delivery to the Contractor, redelivery to the Government, or any inter/intra facility transits.

7.2.2 Consistent with ship’s draft condition, the ship shall remain afloat without any danger of grounding and avoid colliding with all overhead obstructions during all transits.

a) A minimum “Air Draft” clearance of not less than Ten (10) Feet shall be afforded between the highest vertical projection of the vessel at mean high water, all bridges and any cables passing above/across the marked channel along the entire route.

7.2.3 The minimum amount of water under the deepest / lowest projection from keel baseline at all times all tides during transit/approach shall be as follows:

a) From the sea buoy to a point in the navigable channel where the contractor takes delivery of the vessel, minimum clearance shall be 3 Feet of water under the lowest projection at mean low water.

b) From the point in the navigable channel where the contractor takes delivery of the vessel, and vessel has Pilot aboard with adequate tug support to proceed dead stick to the intended pier, minimum clearance shall be 2 Feet of water under the lowest projection at mean low water.

7.2.4 Offerors must submit with their proposals copies of all the latest National Oceanographic and Atmospheric Administration (NOAA) (or US Army Corps of Engineers) waterway approach charts to their facility. Charts are to show the entire route of transit from the sea buoy to the Contractor’s facility, including any for proposed inter/intra facility transits. Charts must provide adequate demonstration that the Offeror has positively determined the route(s) providing safe vessel transit.

7.2.5 Offerors must submit an approach chart with their proposals. The approach chart shall be equal to the berthing chart in dimensions and contain the following data:

7.2.5.1 Offerors shall furnish current depth soundings for the approach to the pier and/or dry-dock from the main channel.
