ICS CLASS: VESSEL REQUIREMENTS FOR NEW PANAMAXES
THE PANAMA CANAL AUTHORITY (ACP) REMINDS THAT VESSELS ARRIVING AT CANAL WATERS, WHETHER FOR DOCKING OR TRANSITING THE PANAMA CANAL, MUST COMPLY WITH VESSEL REQUIREMENTS, AS STATED IN THE MARITIME REGULATIONS FOR THE OPERATION OF THE PANAMA CANAL AND OP’S NOTICE TO SHIPPING NO. N-1-2013 (REV 1), “VESSEL REQUIREMENTS.”
THE PURPOSE OF THIS ADVISORY IS TO INFORM THE SHIPPING COMMUNITY OF THE DEFINITIONS AND REQUIREMENTS APPLICABLE TO ALL VESSELS INTENDING TO TRANSIT THE PANAMA CANAL’S NEW LOCKS.
DEFINITIONS
- TROPICAL FRESH WATER (TFW): TROPICAL FRESH WATER OF GATUN LAKE, DENSITY 0.9954 TONS/M³ AT 29.4ºC. (NOTE: TRANSITION TO FRESH WATER FREQUENTLY ALTERS TRIM OF LARGE VESSELS BY THE HEAD)
- PANAMAX: ALL SUPERS THAT COMPLY WITH THE SIZE AND DRAFT LIMITATIONS OF THE ACTUAL LOCKS; NAMELY, 294.13 METERS IN LENGTH BY 32.31 METERS IN BEAM BY 12.04 METERS TFW DRAFT.
- PANAMAX PLUS: ALL PANAMAX VESSELS AUTHORIZED FOR TFW DRAFTS GREATER THAN 12.04 METERS AND APPROVED FOR TRANSIT OF THE NEW LOCKS
- NEW PANAMAX: ALL VESSELS WITH DIMENSIONS GREATER THAN PANAMAX OR PANAMAX PLUS THAT COMPLY WITH THE SIZE AND DRAFT LIMITATIONS OF THE NEW LOCKS; NAMELY, 366 METERS IN LENGTH BY 49 METERS IN BEAM BY 15.2 METERS TFW DRAFT.
- SAFE WORKING LOAD (SWL): THE SWL SHOULD NOT EXCEED 80 PERCENT OF THE DESIGN LOAD
MAXIMUM LENGTH
- THE MAXIMUM LENGTH OVERALL INCLUDING BULBOUS BOW FOR COMMERCIAL OR NON-COMMERCIAL VESSELS ACCEPTABLE FOR REGULAR TRANSIT IS 366 METERS. VESSELS TRANSITING THE CANAL FOR THE FIRST TIME, WHETHER NEWLY-CONSTRUCTED OR NEWLY-MODIFIED, ARE SUBJECT TO INSPECTION AND PRIOR REVIEW AND APPROVAL OF VESSEL PLANS. VESSELS NOT RECEIVING ADVANCE APPROVAL AND/OR NOT IN COMPLIANCE WITH CANAL REQUIREMENTS MAY EXPERIENCE DELAYS OR DENIAL OF TRANSIT
- THE MAXIMUM LENGTH FOR INTEGRATED TUG-BARGE (ITB) COMBINATION ACCEPTABLE FOR REGULAR TRANSIT IS 366 METERS OVERALL, INCLUDING THE TUG. A TUG-BARGE COMBINATION MUST TRANSIT TOGETHER AS ONE UNIT WITH THE TUG SUPPLYING PROPELLING POWER.
- THE MAXIMUM AGGREGATE OVERALL LENGTH FOR NON-SELF-PROPELLED VESSELS ACCEPTABLE FOR TRANSIT IS 305 METERS, INCLUDING ACCOMPANYING TUGS. ACCOMPANYING TUGS MUST LOCK THROUGH WITH THE NON-SELF-PROPELLED VESSEL. ONE TIME ONLY TRANSITS THAT EXCEED THESE LIMITATIONS MAY BE PERMITTED ON A CASE-BY-CASE BASIS WITH PRIOR APPROVAL OF THE EXECUTIVE MANAGER FOR TRANSIT OPERATIONS, AND SUBJECT TO REQUIREMENTS LISTED IN SECTION 2.K(9), OF THE OP’S NOTICE TO SHIPPING NO. N-1-2013 (REV 1),”VESSEL REQUIREMENTS.”
MAXIMUM BEAM
- THE MAXIMUM BEAM FOR COMMERCIAL OR NON-COMMERCIAL VESSELS AND THE INTEGRATED TUG-BARGE COMBINATION ACCEPTABLE FOR REGULAR TRANSIT IS 49 METERS, MEASURED AT THE OUTER SURFACE OF THE SHELL PLATE, INCLUDING ALL PROTRUDING STRUCTURES BELOW THE TOP OF THE LOCK WALLS.
- THE MAXIMUM BEAM FOR NON-SELF-PROPELLED VESSELS, OTHER THAN INTEGRATED TUG-BARGE COMBINATIONS, ACCEPTABLE FOR TRANSIT IS 36.5 METERS. ONE TIME TRANSIT OF WIDER VESSELS MAY BE PERMITTED WITH PRIOR APPROVAL OF THE EXECUTIVE MANAGER FOR TRANSIT OPERATIONS, AND SUBJECT TO REQUIREMENTS LISTED IN SECTION 2.K(9), OF THE OP’S NOTICE TO SHIPPING NO. N-1-2013(REV 1), “VESSEL REQUIREMENTS”
- VESSELS THAT CARRY CARGO WITHIN 2.5 CENTIMETERS OR LESS OF THE EXTREME BEAM MUST HAVE APPROVED PROVISIONS, SUCH AS RUBBING BANDS TO PROTECT THE CARGO, SHOULD THE VESSEL REST ALONGSIDE THE WALL WHILE IN THE CHAMBER. THE MAXIMUM BEAM OF 49 METERS MUST NOT BE EXCEEDED BY THE CARGO PROTECTION METHOD.
PROTRUSIONS
- ANYTHING THAT EXTENDS BEYOND A VESSEL’S HULL, EXCEPT FOR THE MAIN ANCHORS, SHALL BE CONSIDERED A PROTRUSION AND SUBJECT TO ALL APPLICABLE REGULATIONS AND LIMITATIONS.
- THE ACP IS NOT RESPONSIBLE FOR DAMAGES TO PROTRUSIONS, WHETHER PERMANENT OR TEMPORARY.
- VESSELS WITH PROTRUSIONS MAY BE PERMITTED TO TRANSIT PROVIDED THAT SUCH PROTRUSIONS WILL NOT INTERFERE WITH THE SAFE TRANSIT OF THE VESSEL OR PRESENT A HAZARD TO CANAL STRUCTURES AND APPURTENANCES, AS DETERMINED BY THE EXECUTIVE MANAGER FOR TRANSIT OPERATIONS. BEFORE TRANSIT IS PERMITTED, THE MASTER OF THE VESSEL WILL BE REQUIRED TO COMPLETE A FORM “UNDERTAKING TO RELEASE AND INDEMNIFY” TO EXONERATE AND INDEMNIFY THE ACP FROM LIABILITY IN CASE OF AN ACCIDENT OR DAMAGES SUSTAINED TO OR AS A RESULT OF THESE PROTRUSIONS.
- VESSELS WITH PERMANENT PROTRUSIONS MUST, PRIOR TO PROCEEDING TO THE CANAL, FURNISH DETAILED INFORMATION REGARDING THE PROTRUSION(S), INCLUDING PLANS AND REQUEST AUTHORIZATION FOR TRANSIT. ADVANCE INFORMATION WILL MINIMIZE THE POSSIBILITY OF DELAYS OR DENIAL OF TRANSIT. FOR DETAILED INFORMATION, CONTACT THE EXECUTIVE MANAGER FOR TRANSIT OPERATIONS.
DRAFT
- THE MAXIMUM PERMISSIBLE DRAFT FOR CANAL TRANSITS HAS BEEN SET AT 15.2 METERS. TROPICAL FRESH WATER (TFW) AT A GATUN LAKE LEVEL OF 25.91METERS OR HIGHER. GATUN LAKE DENSITY IS 0.9954 TONS /M³ AT 29.4 ºC. THIS PROVIDES A SAFE NAVIGATIONAL MARGIN OF AT LEAST 1.52 METERS OVER CRITICAL ELEVATIONS IN THE NAVIGATIONAL CHANNELS AND A CLEARANCE OVER THE LOCK SILLS OF 3.05 METERS.
CONSTRUCTION, NUMBER, AND LOCATION OF CHOCKS AND BITTS
- THE MOORING REQUIREMENTS, AS STATED IN SECTION 8.A OF OP’S NOTICE TO SHIPPING NO. N-1-2013 (REV 1), “VESSEL REQUIREMENTS,” WILL REMAIN UNCHANGED FOR PANAMAX VESSELS. FOR THE PANAMAX PLUS AND NEW PANAMAX VESSELS, THE MOORING REQUIREMENTS WILL BE AS STATED IN SECTION 8.A EXCEPT AS REQUIRED HEREIN. NAMELY, THE CHOCKS AND BITTS WILL BE USED BY ACP TUGS ASSISTING VESSELS THROUGH THE NEW LOCKS, AS WELL AS FOR MOORING VESSELS INSIDE THE LOCKS. ALL CHOCKS FOR THE PANAMAX PLUS AND NEW PANAMAX VESSELS SHALL BE DOUBLE CHOCKS AND SHALL HAVE A THROAT OPENING AREA OF NOT LESS THAN 900 SQUARE CENTIMETERS (PREFERRED DIMENSIONS ARE 355 MILLIMETERS X 255 MILLIMETERS) AND SHALL BE CAPABLE OF WITHSTANDING A SWL OF 90 TONS (883KN) IN TOWING OPERATIONS AND A MINIMUM SWL OF 64 TONS (628 KN) IN MOORING OPERATIONS FROM ANY DIRECTION, IN ACCORDANCE WITH SECTION 8.A (5), OF THE OP’S NOTICE TO SHIPPING NO. N-1-2013 (REV 1), “VESSEL REQUIREMENTS.”
