2. Overview FFG entering port grounding LSD unrep near collision
T-AE unrep near collision
Yukon/Denver collision
Discussion (throughout)

3. FFG Entering Port FFG entering foreign port for bilateral ex
Language barrier
Diplomatic clearance delayed
9 hour delay getting into port
Stationed Sea and Anchor
1657: proceed to pilot pickup

4. FFG (cont) Pilot boat skips them Proceed out of channel
Sunset observed
Note: Avoid entering port later than 1700
Made second approach
No pilot available
Permission not granted -- clear channel

5. FFG (cont) CO/XO: Anchor outside the channel CO went to CIC
XO (conn) maneuvered to port
Nav informed XO it was a different set of buoys -- standing into shoal water
XO disagrees -- full rudder turn to port

6. FFG (cont) Ship ran aground Sonar dome damaged
One propeller blade sheared

7. FFG - findings Tripwire (NLT 1700) ignored
No one assumed responsibility of oversight
Language barrier anticipated?
Committed to channel w/out permission
Nav advised shoal water -- stop ship to investigate
LACK OF SUPERVISION --> MISHAP

9. LSD Near Collision Conducting UNREP operations
Approach conducted 2 hours of approaches and breakaways (6) -- no lines
Ship approached -- dry hookup
Intent was to hookup again -- 50k gals fuel

10. LSD (cont) Approach ship alternated helmsman Conn passed to new Ensign
Dept Head OOD
Dept Head coach for Conning Officer
Qualified OOD was Helm Safety
CO and XO were both on the bridge

11. LSD (cont) Maintained station 160-180 ft
Rudder: 5 deg, occasionally 10 deg
Rig was passed for final hookup
Permission to tension granted
Word passed “Standby to tension aft”
Spanwire not tensioned immediately

12. LSD (cont) Rudder: Conn coach: shift your rudder Right 15 deg
Moving toward amidships
Approaching amidships from >10 deg left
Past right 15 deg to right full
Conn coach: shift your rudder

13. LSD (cont) CO assumed conn Conn coach formally took the conn
Rudder amidships
Left standard rudder
Various combinations
Conn coach formally took the conn
Spanwire parted
10-40 ft CPA at stern

14. LSD - findings Helm/Safety Officer Helm Safety Officer
Prematurely and erroneously compensated
Failed to maintain ordered course
Did not advise conning officer of situation
Helm Safety Officer
Did nothing to correct when helmsman lost ctrl
Helmsman unconfident due to overbearing nature of helm safety officer

15. LSD - findings
Confusion with regard to conn

16. Discussion

17. T-AE Near Collision Preparing for UNREP
3 things noted prior to approach
Headed into sunrise (start was 0750)
Rigs 4 and 6 both well forward of pivot point
Noise level high due to simultaneous vertrep
Base cse: 080
Using 081/082

18. T-AE (cont) Ship approached 160 flag Conn saw paddle signal to tension
On course 081
Ordered 083
Stations 4 and 6 stationed simultaneously
Ships closed to 120 feet w/in seconds

19. T-AE (cont) Rudder: Stabilized at 100 ft separation
Right 5 degrees
Right 10 degrees
Stabilized at 100 ft separation
Right 15 degrees rudder
Opened distance
Stern CPA of 60 feet

20. T-AE (cont) Ships opened to 200 feet
Rudder amidships -- coasted to 300 feet
Weak links parted at 300 feet

21. T-AE - Findings Conning officer unprepared for sudden tension
Highlines tensioned w/out permission
