The Allegheny Sea Star is a mini tension leg platform (TLP) located in the Gulf of Mexico, Green Canyon block 254. The oil and gas platform is owned primarily by Eni SpA with a 60% interest and by Newfield with 40% interest. It has been active since 1999 and has a capacity of 24,500 barrels of crude oil per day and 1.27 cubic meters of natural gas. The water depth of the oil field is 3,246 feet.
The platform installation project was completed by J. Ray McDermott in 1998 and completed the following year. The project encompasses five subsea production trees along with two riser end manifolds (REM). Eni is the sole operator for production. The company also operates King Kong field in the Gulf.
The Sea Star utilizes a mini tension leg platform. This allows for a smaller footprint yet it can still be installed in deep water. The small size and the unique installation system allow the unit to get closer to other offshore facilities and platforms. The units can be fabricated on shore and easily towed to their location offshore where they are installed. Platforms are less complex and therefore less bulky.
Installation includes the use of long pylons that are placed deep within the ocean floor. The pylons hold the structure that then floats the platform above. The unit is much more streamlined than large, traditional platforms. They are easier and faster to install and are therefore less expensive as well.
The platform allows for expansion and can connect with other nearby wells. It can also be utilized as a temporary station during construction of a main rig. In this case, the platform is used alone.
Eni is an Italian based company that operates globally in the oil and gas industry. They are one of the top 100 Fortune 500 global companies and have a market value equal to $57 billion. They have operations in 73 countries around the world. Eni has had at least a few incidents on their offshore platforms over the years. One incident happened on the Goliat, owned by Eni. The accident occurred offshore of Norway in 2016 when a worker was performing cleanup after an unloading operation. A wire rope snapped, hitting the man across his head causing an injury. The worker was transported to a hospital in Northern Norway for treatment. An investigation was being made into the event. The Goliat is the first offshore oil field in the Barents Sea.
Accidents that occur in the United States must be reported to the U.S. Coast Guard and Department of Transportation. The Bureau of Safety and Environmental Enforcement (BSEE) investigates and reports on offshore accidents. Maritime workers are protected by the Jones Act, which allows those who are hurt due to employer’s negligence to take legal action to obtain compensation for their injuries.
