What does 33 CFR 165.1109 say about LA/ LB deep water pilot areas?
No vessel may enter the POA unless entering or departing LA or LB main channels. Vessels shall pass directly through without stopping or loitering unless stopping is for taking on a pilot. Minimum vessel separation is ¼ mile. Speed limit in the precautionary area is 12kts or less
- The standards of care for reduced visibility state, whenever visibility inside the federal breakwater is less than .5nm the LA/LB traffic center will impose ……. Where appropriate
One Way

Alcohol test within 2 hours of incident and Drug test ASAP but not more than 32 hours after incident.
a. Damaged exceeding $25,000
b. Loss of life
c. Injury requiring more than first aid
d. Spill of 10,000 gals or more of oil.
e. Spill involving a reportable quantity of hazardous substances
What are the pilotage regulations for Los Angeles Harbor?
Vessels of 300GT or more. All foreign vessels entering, shifting within or departing LA/LB Harbors. All tugs arriving from a foreign port
What is the speed limit LA outer harbor?
Tank vessels less than 60,000 metric displacement tons = 8kts
Tank vessels 60,000 metric displacement tons or greater = 6kts
Vessels with draft less than 1.5m = 15kts
Vessels with more then 1.5m draft= 10kts

Tanker Master/ Pilot Conference
a. Contact escort tug operator to confirm number and positions
b. Establish a working frequency
c. Establish destination of tank vessel
d. Discuss any other pertinent info the mater/pilot and escort tug deem necessary.
How do you decide the size of escort tug needed for laden tanker and when must they meet when inbound from sea?
Refer to the tanker force selection matrix in the Mariners Guide. All Laden tankers shall have escort tugs tethered within 2.0NM of the federal breakwater. Zone 2: 3.5 NM from LB Breakwater, escort tugs required for all laden tankers with a static deep draft greater than 16.5 meter. Zone 3: 4 NM from LA breakwater, escorts tugs required for all laden tankers with static deep draft greater than 14.0 meters.
List considerations for minimum under keel clearance
Vessels mean draft, Vessel List and trim characteristics, intended speed along route, squat characteristics, tide and current conditions, past weather impact on water depth, controlling depth of channel, traffic in the area.
Describe tidal range and current
Max tidal range is approximately 9ft. The tidal currents follow the axis of the channels and rarely exceed 1kt
5 things that constitute a marine casualty
a. Damage exceeding $25,000
b. Loss of life
c. Injury resulting in more than first aid
d. Spill exceeding 10,000 gals of oil or hazardous substances
e. Loss of main propulsion or primary steering

Where do escort tugs meet tankers (describe Zones)
3 Tank Vessel Escort Zones:
Zone 1: All Laden tankers shall have escort tugs tethered within 2.0NM of the federal breakwater.
Zone 2: 3.5 NM from LB Breakwater, escort tugs required for all laden tankers with a static deep draft greater than 16.5 meter.
Zone 3: 4 NM from LA breakwater, escorts tugs required for all laden tankers with static deep draft greater than 14.0 meters.
