Ports of Los Angeles – Long Beach § Nation’s largest port complex § World’s 9 th busiest port complex by container volume § Over $235 billion in annual trade § > 14 million TEU’s annually § 47 % of containers entering U. S. § > 235 million metric tons of cargo § > 1 million passengers § ~500, 000 autos § > 50 % of California’s oil § ~3 million jobs nationwide

Dynamic Underkeel Clearance Project… The Challenge…Very Large Tankers enter the Port of Long Beach How can we reduce the risk they touch bottom? M/V Solana passing Jacobsen (Long Beach) Pilot Station. Length: 1, 082 feet Weight: Beam (width): 197 feet Maximum Draft: 296, 681 tons 64. 9 feet 4

Approach to port of Long Beach… Channel dredged to 76 feet Coast Guard set maximum draft to enter port at 65’ 11’ clearance underkeel 5

With Zero Pitch: 76’ channel Example: 1, 100 foot tanker with 65’ draft 65’ Max Draft per Coast Guard 11’ Under Keel Clearance With 1 degree pitch, the draft increases 9. 6 feet! 76’ channel 65’ Max Draft per Coast Guard Result: Only 1. 4 foot Under Keel Clearance! 6

The Present: GO/NO GO decision made using: Site 18 ü CDIP Swell Warnings ü Experience ü Seaman’s Eye ü Observed pitch & roll far enough offshore to permit “bail-out” before committing to channel Site 19 7

Moving to the Future… UKC Program: Stakeholders: & PIER 121 USERS Partners in providing critical weather, wave, and swell information to UKC: 8

The Potential Future: PROTIDE takes predicted: ü water levels, ü currents, ü wave conditions, ü channel depth, ü course, ü ship dimensions, and ü vertical ship motion (roll/pitch/squat) …and calculates the under keel clearance & bottom touch probability. PROTIDE is now used in three harbors in the Netherlands to support the operational process (Port of Rotterdam, Port of Amsterdam & the Eemshaven). 9

Goals of Dynamic Underkeel Clearance Project 1. Increase safety by reducing the risk of an accidental grounding caused by the pitch or roll of a large vessel causing it to impact the bottom. 2. Increase efficiency by enabling ship owners and masters to adjust arrival times based on the pitch and roll program being able to predict when pitch and roll will be out of limits to enter port due to unacceptable under keel draft clearance 3. Reduce emissions by enabling larger ships to carry more cargo to enter the POLB, which could reduce overall stack emissions per ton of cargo arriving at the port. 10

Example: A 935 foot tanker weighing 230, 000 tons enters Long Beach INPUTS to PROTIDE: 1. Ship Info: Outputs: Predicted UKC and Probability of Touch Predicted pitch is a max of 0. 75 degrees Predicted roll is a max of 6. 15 degrees Request ID 11 Ship 230, 000 ton VLCC (6 / T 006) Ship dimensions l / w / dwt 285 m 49 m 250000 tons Draft f / m / a 20. 46 m Berth Harbor entrance (23. 16 m / Inbound) Requested time of departure 2014 -08 -22 00: 00 Water displacement 234294 tons GM 7. 78 m GG' 0. 4 m Roll period 13. 71 s Estimation method used Yes Under Keel Clearance Submitted by Take Roes (2014 -08 -27 09: 29) Risk of Touch 2. Environmental Info: Water level, tide, weather, sea, and swell Resulting Underkeel Clearance ranges from: 3. 9 m at the start of the transit to 4. 1 m at the end of the transit Risk of touching bottom is: 0. 020% at start of transit, decreases to. 0038% in the middle, and increases to. 0050% at the end Determination: The transit is safe Start of transit Roll Pitch End Start of transit End 13

Other potential UKC applications: ü Unique vessels, ü Bad weather, ü Larger Container & Cruise Ships ü Other ports Ship entering Long Beach with new cranes Ship exiting Long Beach in Hurricane Marie swells 14

Questions? Comments? Summary: The key to the safe movement of all vessels, now and in the future, is accurate and reliable, actual and predictive, weather, swell, and wave information 15
