Drilling Ships A.K.A Drillship

Drilling ships are part of the group of ships that are designed to complete a specific task. Drilling ships are becoming more and more important within our society because of their ability to drill for oil or other gasses in the middle of the ocean. These places that drilling ships can drill for natural resources would take forever just to build and transport an oil rig to drill without the one hundred percent chance that there will even be oil there.

Technology has made offshore drilling a lot more profitable and efficient. Drilling ships are becoming cheaper to build even with the ever-increasing demands by the oil industry for finding oil in some of the harshest conditions. The main reason drilling ships are being so sought after these days are for a few reasons one being lower cost, the ability to run efficiently with lower emissions and ability to drill in deep water.

The first reason being the decreasing cost of making the ships while reading New Rig Designs: Shell and Frontier joint venture to build the "Bully" drillship I found this quote “The drillship design sets a new standard and offers a flexible, smaller but highly capable vessel suited for deep-water and arctic drilling, while reducing the construction and operational costs compared to new build drilling rigs of similar capability.” This quote is an example of the cost difference between the new drilling ships and the oilrigs that were used for this purpose. Drilling ships have not necessarily replaced drilling rigs they have taken somewhat of a supporting role because some of the same companies that use drilling ships have drilling rigs as well.

The second reason being the ability to operate at a cost affective rate with reduced cost and still be able to function with low emission output. While reading New Rig Designs: Shell and Frontier joint venture to build the "Bully" drillship I found a quote to help you understand my reasoning “Through the use of these innovations, the design calls for less crew and fuel, allowing for competitive day rates while offering safer operations. The new drillship will have a significantly reduced environmental impact due to lower emissions through reduced fuel consumption, high-efficiency/low-emission engines and lower steel use for construction.” This quote expresses the lack of effect that drilling ships have on the environment while still keeping companies competitive within the drilling industry.

The third reason drilling ships are becoming more poplar within the oil drilling industry is there ability to drill in deep waters while reading Double-hull drillship, automated drilling, improve operability by Gaddy, Dean E I found this quote “The drillship will be capable of drilling to 25,000 ft. in water depths up to 7,500 ft. If needed, the vessel can later be fitted to drill in 10,000 ft. of water by adding additional risers. The vessel's chief design consideration centers on exploratory well drilling, but it can also be used for development drilling programs. Eventually, it may serve as a floating production storage and offloading (FPSO) vessel.” This Quote shows two things one the versatility that the drill ships have and two the depth that the drill ships can possible drill.

A new location that is being talked about for drilling is in the arctic sea companies know that there is oil out there under the water. The problem that a lot of these companies are getting into is finding a way to get out there and stay out there. Due to the extreme conditions drilling in this area has proven very difficult. Since oil is a very hard substance to clean up of once It is spilled an oil spill is not something an oil company can afford and neither can the surrounding wildlife. The E.P.A (environmental protection agency) is very strict within the maritime industry but regulations may vary depending on where the ship is located during the infraction. In the arctic seas the E.P.A is very strict this is because of wild life that lives in the area. While reading EPA issues air permits to Shell for oil drilling offshore Alaska by Dittrick, Paula “The permits will allow Shell to operate the Discoverer drillship and a support fleet of icebreakers, oil spill response vessels and supply ships for up to 120 days each year in the Chukchi Sea and Beaufort Sea Outer Continental Shelf starting in 2012.” This quote expresses how strict the conditions by the fact the drillship need a fleet of icebreakers and how strict the E.P.A is by the fact Shell only received a 120.

Drilling ships A.K.A Drillship

INTRO
Drilling ships are part of the group of ships that are designed to complete a specific task. Drilling ships are becoming more and more important within our society because of their ability to drill for oil or other gasses in the middle of the ocean. These places that drilling ships can drill for natural resources would take forever just to build and transport an oil rig to drill without the one hundred percent chance that there will even be oil there.

DRILL SHIP COMPARED TO OIL RIG
When comparing drill ships to oilrigs there is a big difference between their capabilities. Oilrigs are capably of drilling deep for oil but are very limited to the depth of the water they are allowed to drill for example, “in rigs with a drilling capacity of 35,000 feet in water of 550 feet depth” the main reason drilling ships are becoming more popular is mainly because of the depths they can drill. Drill ships can drill through deep water unlike oilrigs. Which means oil can be found deeper out in the water this will allow for more exploration for example, “The application areas are: Drilling subsea wells with a conventional subsea BOP and marine riser system in up to 5,000 ft. water depth and ability to drill deep-water exploration wells with a split BOP and High Pressure (HP) riser system in up to 12,000 ft. water depth.”

TECHNOLOGY OF DRILL SHIP
Technology has made offshore drilling a lot more profitable and efficient. Drilling ships are becoming cheaper to build even with the ever-increasing demands by the oil industry for finding oil in some of the harshest conditions. The main reason drilling ships are being so sought after these days are for a few reasons one being lower cost, the ability to run efficiently with lower emissions and ability to drill in deep water.

COST
The first reason being the decreasing cost of making the ships while reading New Rig Designs: Shell and Frontier joint venture to build the "Bully" drillship I found this quote “The drillship design sets a new standard and offers a flexible, smaller but highly capable vessel suited for deep-water and arctic drilling, while reducing the construction and operational costs compared to new build drilling rigs of similar capability.” This quote is an example of the cost difference between the new drilling ships and the oilrigs that were used for this purpose. Drilling ships have not necessarily replaced drilling rigs they have taken somewhat of a supporting role because some of the same companies that use drilling ships have drilling rigs as well. The company Seadrill is a company that has drill ships and oil rigs ne of their oil rigs is called West eminence it will drill through 10,000 ft. of water and drill to a depth of 30,000 ft. at a daily rate of 623,000 U.S. dollars. They have a drill rig called West Gemini that will drill through 10,000 ft. of water and to a depth of 35,000 ft. at a daily rate of 447,000 U.S. dollars.

The second reason being the ability to operate at a cost affective rate with reduced cost and still be able to function with low emission output.
