Conclusions

Slide3

Lone Star Harbor Safety Committee

A

public forum to address

navigation

safety-related matters involving the ports of Houston, Galveston, Texas City, and Freeport including the associated waterways of the Gulf Intracoastal Waterway and offshore lightering zones

.

R

egional

expertise and insight to address such issues as vessel traffic management, anchorage management, communications, security, significant/heavy weather preparations, maritime traffic disruption/restoration, process improvements, and any other related topics dealing with the MTS.

Slide4

LONE STAR HSCMembership

Slide5

LONE STAR HSCDredging Subcommittee

Provide

a forum to discuss, communicate, and as necessary make recommendations

regarding

dredging issues as related to safety within the Houston, Texas City, Galveston area waterways

Slide6

Houston/Galveston Complex

Ports of Houston, Galveston, and Texas City

Home to the world’s 2nd largest petrochemical complex

Slide7

Grounding at Dock

A vessel is ordered in with no dock restrictions and given instructions for loading cargo

The vessel is moored in good order

The vessel loaded all of the cargo despite grounding on their bow (3M)

Pilot attempts to get vessel U/W

Slide8

A Busy Port

Slide9

Possible Factors

Surveys were current and

IDed

the area of shoaling- Facility did not tell vessel about the area of shoaling

Construction of a pier required mooring further up the dock

M

ound possibly caused by tugs assisting vessels across the channel

Vessel did not use a lead line and possibly did not get off the vessel to check drafts

Slide10

Hurricane Rita

Slide11

Hurricane Rita

September 24, 2005 near Sabine Pass, TX

4th-most intense Atlantic hurricane ever recorded

Most intense tropical cyclone ever observed in the Gulf of Mexico

Post-Rita Response

USCG, USACE, and NOAA surveyed federal channels to locate shoaling and obstructions

due to Hurricane Katrina, several survey vessels were already mobilized in close proximity to the HGC and able to quickly perform post-storm surveys

pre- and post-hurricane surveys were compared to help provide a critical analysis of the waterways prior to allowing ship traffic to re-enter the HGC, and used to request emergency funding for the dredging of channels and the removal of obstructions

Slide15

Post-Rita Response

In 2005, however, pre-hurricane surveys in the HGC were not completed for all waterfront facilities, and post-hurricane surveys were completed only by a small number of waterfront facilities

Fortunately, little shoaling occurred in the HGPC as a result of Hurricane Rita, no underwater obstructions were detected, and facilities suffered only minor damage

Slide16

Post-Rita Response

Federal Responders do not conduct surveys at non-federal government facilities and that the responsibility to survey a facility’s docks and moorings rests with the facility itself,

Dredging

Subcommittee developed a proactive navigation preparedness initiative in the form of a “Best Practice Guidelines” for waterfront

facilities.

Slide17

MSIB 07-07

Slide18

MSIB 07-07

Recommends

Annual survey conducted by the waterfront facility

prior to the start of hurricane season, and

Establishment of a plan to have an emergency post

storm survey of docks and moorings completed as

soon as possible

Slide19

MSIB 07-07

Purpose of Surveys

Assist the USCG in determining whether or not

vessels can safely arrive at a facility’s dock or

mooring,

Provide valuable documentation of damage or loss

for insurance companies, and

May support an emergency declaration and access to

Federal financial assistance.

Slide20

Slide21

MSIB 01-08

Noted a significant number of dockside groundings

Cited reporting requirements (CG-2692)

Facilities should conduct periodic surveys and report survey info to Pilots, Vessel Agents and arriving Vessels

Slide22

PCT

PCT Goals

1) Communicate, communicate, communicate

2) Coordinates port wide posture changes in response to all threats/all hazards

3) Ensures Port reopening and prioritization of maritime traffic optimizes timely supply of critical commodities to facilities

4) Assists Federal/State/Local responders with local knowledge, expertise and supplies

Slide32

Hurricane Ike

9/11/08 2300

Port Closed9/13/08 1000 Post-storm Waterways and Infrastructure Assessments Extensive surveys, to include aerial assessments, initial centerline surveys, aids to navigation assessments, and waterside facility assessments. Port Coordination Team (PCT) efforts with port stakeholders are essential for a quick and efficient assessment of all COTP waterways. Partnering with industry to restore navigation on the COTP zone waterways is essential in the process of reopening this economically critical port. 9/15/08 0600 VTS Houston-Galveston Resumes Full Operations 9/15/08 0700 Shallow Draft Vessel (≤ 12ft) Begin Transits in HSC & GICW (MM350 to MM342 w/in COTP Zone Houston-Galveston) – Within 48hrs9/15/08 Daylight Transits (38ft - Port of Freeport)9/17/08 Daylight Transits (38ft - Sea Buoy to Shell / 30ft - Shell to Turning Basin; 30ft - Port of Galveston; 16ft - Port of Texas City) – Within 96hrs9/23/08 HSC Open to Project Depth

Slide33

Hurricane Ike

Approximately 65-75% of terminals had conducted pre-storm surveys – Ports of Houston, Galveston, Texas City

Percentage is a significant improvement compared to pre-Rita levels

Terminals with recent surveys sent to “top of the line” – Priority with regards to Facility Inspections to render re-opening status.

Slide34

Conclusions

Lone Star HSC initiative

to encourage terminals to conduct pre-storm surveys aided in the quick re-opening of the Houston Ship Channel Post-Ike

Port Coordination Team –

Strong relationships,

cooperative communication

Expedite economically vital port recovery

Many

terminals still do not understand they are responsible for post-storm surveys of their facilities
