One of the biggest disasters in the Gulf of Mexico was the oil rig collapse that led to a vast amount of wreckage to fall to the ocean floor. And, before any debris could be picked up and removed, the sediment that layered the wreckage needed to be excavated using a pipe-like tool that reached 900-feet from the surface of the ocean to where the debris was located.
The problem with the Gulf Oil Crisis became visibility. The water was extremely murky for any camera images, which means surface sonar was used to provide the operator with a view of down below. However, there was a limited image accuracy. This led to a multitude of issues:
• Damaged equipment
• Operator mistakes
• Significant slowdowns
However, AquaTech, which is the leader in underwater equipment in the Survey, Diving, Naval, ROV and Dredging industries, came up with a guidance system that would position the sonar unit at the end of the tool, near the action.
What Are The Main Benefits?
• Best Possible Protection – It allows for precise view of the area, decreasing the risk for damage to equipment
• Better Data Delivery – It can give work teams current, more precise sonograms
• Time Savings – Workers can use the precise images to carry out their complicated tasks in quicker time
• Monetary Savings – With PoE energy efficiency, the cost of the unit pays for itself in no time
• Easy Setup – The compact design will perfectly align with the system configuration
With this kind of proximity, it would lead to more precise sonograms for the tool operator. And, the sonogram information would need to travel the entire 900-feet from the ocean floor to the surface work area. This was the challenge that AquaTech faced – to come up with a long-distance communications channel that permitted high-density data rate.
What Their Solution for the Gulf Oil Crisis Came Out To Be?
Aqua Tech looked at an array of solution that would help them turn the idea into a reality. The team looked at three things:
• Ethernet extenders
• Large conductors
• Boosting power
When they realized that the most sense came from extenders, they had to settle on a company to do business with… and that company was Enable-IT and its Enable-IT 828P.
Implementation Of The 828P
After the AquaTech guidance system, the 828P held up its end of the bargain with its high performance. A big reason it’s so effective is because it’s so compact. The configuration demanded that the device be installed every 350 feet, which lead to a number of repeaters from the ocean floor to surface.
The four units that were employed were stored in a tiny pressure vessels. Therefore, bulky extenders would not have worked for the setup.
With the 828P, the data delivery rose to a new level. This means more accurate sonograms were produced from the ocean floor depth, which had to travel 900 feet, and did so at lightning speed. This allowed tool operators to get a better view of the Gulf Oil Crisis wreckage area.
The 828P allowed for precision guidance and improved data accuracy, meaning removal and excavations were done in record time – no expensive tool damage done – unlike the previous systems.
AquaTech’s, Al Rougeau, noted that the information going into the system arrived to its destination completely intact, which means the 828P units were pretty obvious. No repeaters were involved. If a non-standard Ethernet protocol was used, the obviousness would still be there.
The 828P unit proved itself to be friendly on budgets, costing much less than other available solutions. And, it continues to pay for itself by being energy-efficient. A main reason is the 828P’s PoE design, getting rid of the need to use extra conductors.
Rougeau said the sediment removal tool was invaluable, and with these kinds of operations increasing, he believes the company will use more Enable-IT devices.
