Interview Flashcards
Where are the fire stations
Berths 194-195 44 85-86 Fish Harbor
Vincent Thomas bridge
1150 feet wide
165 felt tall
Middle 500 feet is 185 feet tall
What to consider when determining UKC
Trim and list characteristics Depth of transit area Depth of berth or anchorage Tim and current conditions Weather impact
UKC transiting LA
From approach buoy 1 to buoy 11 min UKC is 10% of vessels draft
From buoy 11 in UKC is 2 feet and must remain afloat while at berth
Outer harbor shifts require 3 feet UKC
B7 & 11 require 4 feet UKC when vessels draft is more than 50 feet
All other anchorages are 2.5 feet
Controlled navigational areas
East channel Slip 93 (cruise terminal) Entire west basin Pier 300 channel
Pilot ladder
5 step must be a spreader
Spreaders are 180cm long
Max 8 steps between spreaders
Steps are 49 cm wide and no more than 30-38cm apart
High winds
Small craft advisory will be issued for sustained winds of 21 to 33 knots potentially combined with wave heights exceeding 10 feet
Visibility restrictions
Tankers 150,000 DWT or greater need 1 mile
Greater than 60000 but less than 150000 0.75 miles
Vessels 45’ draft or more require 0.75 miles
All other tank vessels require 0.5 miles
All other vessels are 3X their LOA
Reduced Visibility
When visibility drops below 0.5 miles VTS will impose one way traffic.
When getting underway in reduced visibility shoreside radar and a PPU should be readily available for use.
If reduced visibility is encountered after getting underway pilot should take appropriate precautions to minimize risk which include continuing, anchoring, reducing speeds, shore based radar, additional tugs
Windage area
50 tons of force is required to hold a ship beam to the wind if 1000 square meters with 60 knots 5000 square meters with 28 knots 10000 square meters wi5 18 knots of wind (Big MOL ships have this much windage)
11 things to be considered when getting underway during inclement weather
Traffic in the area
Transit speeds
Maneuvering characteristics of vessel
Quality of vessels radar
Vessels size and draft in relation to transit area
Number type and power of tugs
Number and power of thrusters
Maneuvering room at various stages of transit
Quality of vessels bridge team
Special circumstances (dredges, obstructions)
Wind direction in relation to planned maneuvers
Anchoring guidelines
Have a licensed English speaking officer on watch at all times.
When wind up screeds 40 knots vessel will have power plant on standby and a 2nd anchor ready
When winds reach 40knots VTS will maintain watch for vessels dragging anchors
Tug escorts
An escort tug is require for all tankers with 5000 M/T of product or more
Zone 1- 2 miles seawards of the breakwater
Zone 2- 3.5 mile from the LB breakwater for all tanker with draft more than 16.5m
Zone 3- 4 miles from the LA breakwater for all tanker with draft more than 14m
Pre escort conference.
Contact escort tugs to confirm number and positions
Establish radio frequency to be used
Establish destination of tank vessel
Discuss any other pertinent info with the master pilot and tug captain
Ensure anchors are ready for emergency
