PortMiami “The Cruise Capital of the World” Contributes more than 41 billion annually toMiami-Dade County Miami’s second largest economic engine Generates approximately 324,000 direct andindirect jobs Close to 20 cruise lines berthing 45 ships,PortMiami moved close to 5 million cruisepassengers during 20162

PortMiamiAtkins has been assisting PortMiami on severalkey assignments in support of their cruise berthsover the past 10 years.1. PortMiami North Bulkhead Realignment Program2. NCB 1-6 Scour Bowl Restoration3. NCB 1-6 Cruise Bulkhead Cathodic Protection4. NCB 1-6 Seafloor Stabilization Pilot Program5. Marine Improvement to Berth 7, Cruise Terminal A6
North Bulkhead RealignmentProgram7
PortMiami North BulkheadRealignment Program2035 Port Master Plan recommended the development ofnew cruise berths to accommodate future demand.The fifteen year mid-term planning range for new cruiseberths was adopted into the Miami-Dade CountyComprehensive Development Master Plan (CDMP) onOctober 2, 2013 by the Miami-Dade County Board of CountyCommissioners. Currently the Port has six (6) north berths in operation Two (2) additional berths were considered (Berth 7 and Berth 8)8
PortMiami North BulkheadRealignment Program9
PortMiami North BulkheadRealignment Program10
PortMiami North BulkheadRealignment ProgramThe Port entered into an MOU with a terminal operatorto construct new berth 7 along the north side of thePort.Royal Caribbean Cruise Lines (RCL) beganconstruction of this new berth on February 27, 2017.Procured as a DFBOM-T, overall cost of the newterminal is approximately 216M.Second P3 initiative that PortMiami has done.11

NCB 1-6 Scour Bowl Restoration13
NCB 1-6 Scour Bowl RestorationThe objective of the scour bowl restoration is to prevent theexisting scour bowls from undermining the integrity of theembedment of the existing bulkhead wall. The proposedsheet pile toe wall combined with a concrete fill betweenthe existing wall and proposed wall will offer passiveresistance and stabilize the wall preventing sheet pileembedment failure. The target elevation to fill the scourbowls is at EL. (-) 37.0 NGVD,14

NCB 1-6 Scour Bowl RestorationA multi-beam bathymetric survey was done by Morgan &Eklund in 2015 and updated in 2016. This information wasused by Atkins to confirm the presence (or lack thereof) ofpropeller washouts, scour bowls and other sea bottomanomalies that may have impact on the existing bulkheads.ScourBowlNo.CruiseTerminalBay No.Station3G264D28 to 3056789GDGDD333639535731 7534 00to36 0040 4543 1047 4064 1569 00SheetPile 33533Other Scour bowls along the North Bulkhead16

NCB 1-6 Bulkhead CathodicProtection19
NCB 1-6 Bulkhead CathodicProtectionThe objective of the Cathodic Protection program is todevelop a plan for the installation of a ten (10) year(minimum) cathodic protection system for the existing steelsheet pile bulkhead along North Cruise Berths 1 through 6.Atkins and their subconsultant, Vector Corrosion Services,evaluated the use of corrosion management (cathodicprotection) to reduce the rate of corrosion of the steel sheetpilings (below water) and thereby preserve the remainingstructural integrity which would gain additional service life.Corrosion management in the form of cathodic protection isa proven cost effective method and may be applied to steelsheet pile bulkheads of the age installed along the Project20
NCB 1-6 Bulkhead CathodicProtectionData sets were utilized forthe corrosion rate analysisEach data set containedmeasurements at the top,mid-height and bottom ofwall.Corrosion rate selected foranode design was 3.5 mpy.21
NCB 1-6 Bulkhead CathodicProtection22
NCB 1-6 Seafloor StabilizationProgram23
NCB 1-6 Seafloor StabilizationProgramThe purpose of the seafloor stabilization program is toimprove the characteristics of the low quality rock strata atthe base of the bulkheads. The stabilization programunder evaluation is a pilot program that would addressabout 500 feet of the total 7,000-plus linear feet ofbulkhead serving Berths 1 through 6.The seafloor at the toe of the sheet pile typically consists ofpoor quality limestone. Stabilization of the seafloor isplanned to strengthen the limestone, increase resistanceagainst a toe failure of the sheet pile wall, and help protectagainst scour adjacent to the sheet piles.24

NCB 1-6 Seafloor StabilizationProgramThe suggested location for the pilot program implementation iswithin the limits of Berth 5. The area from station 58 80 to station63 80 is located within the limits of the original 1960’s bulkheadwall and does not overlap with any of the scour bowl restorationareas .26

Marine Improvements North CruiseBerth 7 – Cruise Terminal A28
Marine Improvements North CruiseBerth 7 – Cruise Terminal AIn a public-private partnership (P3) agreement withMiami-Dade County, Miami Cruise Terminal A, LLC, willbe constructing and operating a new signature cruiseterminal (Cruise Terminal A), provisioning building,parking garage, intermodal areas and a new cruise shipberth all to be located on the northeast quadrant ofPortMiami. The new cruise berth needs toaccommodate a 400 meter LOA (1,312 feet) StretchOasis Class RCCL cruise ship with extended mooringline zones, both forward and aft of the ship. Whencompleted, new Cruise Berth 7 will have an overalllength of about 443 meters (1,454 feet)29
