27-MAR-2004 – Devon Louisiana Corporation

Remarks: In preparation to begin Plugging and Abandoning operations, the Jack-Up, a 200 Class vessel, had tagged the seafloor with its legs and was moving in position adjacent to the GA 393 "C" platform. When the vessel was very near the platform, the captain placed the vessel's controls in reverse to maneuver the vessel, and the controls did not immediately respond. As a result of this lag in control response time, the vessel continued to move forward and came into contact with the platform. The intermediate landing, along with its handrail, was bent as a result of the vessel coming into contact with the platform. The crane on the vessel received very slight damage. All of the wells were shut-in, and no pollution or injuries occurred as a result of this incident.

29-MAR-2004 – Walter Oil & Gas Corporation

Remarks: An unknown marine vessel struck ST-260-A platform. The north leg of the platform shows a scrape 15 feet above the water line. The crane pedestal was broken and various loose items were strewn across the platform. Two of the main structural members had visual buckling with several structural cross members with broken welds. Some facility piping support brackets were bent. At the time of the collision, it was reported that the fog horn and navigational lights were working. No pollution or injuries were reported.

26-MAY-2004 – Walter Oil & Gas Corporation

Remarks: The platform was struck on the southwest side by a barge being towed by a vessel. The structure sustained a significant amount of damage (approximately $250,000). The weather at the time of the incident was clear. There were no injuries or pollution as a result of the collision.

15-JUL-2004 – Arena Energy, LLC.

Remarks: A 3 legged jack-up boat, owned by Global Industries, was repositioning and lost control and scraped along the side of the D platform. The vessel was unable to compensate for the current and wind conditions during the repositioning maneuver. Above water damage to the platform was minimal, consisting of damage to an out of service vent line beneath the walkway, an electrical cable beneath the walkway, several pipe support braces, and the stairwell on the NE corner of the D Platform. An under water inspection revealed several dents on the NE leg and a scrap on adjacent diagonals non destructive evaluation of the nearby welds indicated no addition problems. There were no injuries or pollution as a result of this event.

17-JUL-2004 – Forest Oil Corporation

Remarks: An unknown large ship hit Forest's WC 172D platform and split open one of the 30-inch legs and incurred other damage. The platform was shut-in after the collision. The platform was inspected and damage was found on the southeast jacket leg, damage to bracing at elevation +12, and damage to a 10-3/4 inch diagonal knee brace from the cellar deck level to the main deck level. The platform was unmanned at the time of the event and there were no injuries or pollution due to the collision.

17-JUL-2004 – Forest Oil Corporation

Remarks: A vessel struck Forest's Oil VR 35 No.1 platform. Damage was minor to the facility. There were no pollution or known injuries.

20-JUL-2004 – El Paso Natural Gas Company

Remarks: A motor vessel was towing a barge, which was being utilized to transport two platform packages when it collided with El Paso’s Ship Shoal, Block 227, A Platform. It is believed that unexpected currents pushed the towed barge into the platform. The collision caused damage to the platform and the two platform packages on the barge. The incident occurred at approximately 1815 hours, in a clear condition – thus visibility and/or navigational lights were not an issue. The estimated damage to the barge cargo is 2 million dollars. The tug did not sustain any damage. A single well that was flowing on the platform at the time of the collision shut itself in on impact. Estimated damage to the platform was about $5,000,000 and consisted of the heliport, stair ways, handrails, grating, solar panels, and structural members. There were no fatalities, injuries or pollution as a result of this event.

22-AUG-2004 – LLOG Exploration Offshore, Inc.

Remarks: While preparing to assist in towing the rig, an anchor boat was approximately 200 feet off of the bow from the Diamond Ocean Saratoga paying out tow wire when both of the generators on the boat tripped off line. The boats CP control system automatic fail safe function caused the props to reverse pitch. As the boat was so close to the rig and before the captain could react and put the controls in the neutral position the boat struck the port sponson directly on the bow at approximately 10 knots. The sponson was crushed in approximately 30 percent of its diameter. The upper structural braces were bent and the lower support frame was pulled away from the top of the hull tearing a hole approximately 2-inch in diameter into the top of the pontoon above the No.1 ballast tank. The cost of the damage is estimated at $900,000. There were no fatalities, injuries or pollution as a result of this event.

26-AUG-2004 – Shell Offshore Inc.

Remarks: During the process of moving off of location after completing operations for Glider Subsea Well No. 3, the drilling rig Noble Max Smith anchor chain impacted the No. 3 subsea wellhead as well as the electro/hydraulic umbilical. The anchor handling vessel had pulled the anchor off bottom and recovery of the wire/chain was in process. The host facility, tension leg platform “Brutus”, was in the process of unloading subsea well No. 3. Brutus personnel observed a loss of electric communication with subesea well No. 3 as well as a loss of hydraulic control to subsea wells 3 and 4. A remotely operated vehicle was lunched and confirmed damage to the umbilical sled, trees, flying leads, and jumper on Glider No. 3 well. Shell reported that the subsea flowline was in tact and there were no hydrocarbon release. The estimated damage was $2,400,000 and there were no injuries associated with the incident.
