1.巴拿馬盲區(qū)要求 Maximum Draft  The maximum permissible draft for Canal transits has been set at 39 feet 6 inches (12.04 m) Tropical Fresh Water (TFW) [Gatun Lake density is 0.9954 gms/cc at 85°F (29.4°C)] deepest point of immersion/load line permitting to those vessels previously approved to transit a this draft. Minimum Draft All vessels transiting the Canal should have sufficient ballast to permit safe handling during transit Up to 425' (129.54 m) - Trimmed so pilot can see the ranges over the forecastle from center of navigation bridge Over 425' (129.54 m) - 8' (2.44 m) forward, 14' (4.30 m) aft, TSW Over 475' (144.80 m) - 18' (5.50 m) forward, 20' (6.10 m) aft, TSW Over 525' (160.02 m) - 20' (6.10 m) forward, 22' (6.71 m) aft, TSW Over 580' (176.80 m) - 22' (6.71 m) forward, 24' (7.32 m) aft, TSW Over 625' (190.50 m) - 24' (7.32 m) forward, 26' (7.93 m) aft, TSW Visibility Restrictions All vessels over 150 feet LOA arriving at Canal waters, whether fordocking or transiting the Panama Canal, are required to report their blind distance (in ship lengths), calculated for Tropical Salt Water, from conning positions 1, 2 and 3. Vessels intending to dock prior to transit must provide the visibility condition for docking and for transit. Vessels intending to dock only (local Calls), must also provide the undocking visibility condition calculated in Tropical Salt Water. 盲區(qū)具體解釋:“Blind Distance” is the forward distance from the bow of the vessel to the closest point on the water’s surface which can be seen from all conning positions in the navigation bridge. An observer’s height of eye of 1.80 meters above the bridge deck must be used to determine this distance, and must be reported in ship lengths. 注意:1號(hào)指揮位置不適用于船舶中心線上配置克令吊的船舶 The Blind Distance at conning position #1 is not applicable to vessels with centerline cranes. |
