Mobile drilling platforms like jack-up rigs and semi-submersibles are used to explore for oil in shallow and deep waters. Offshore engineers design these platforms and oversee drilling and production operations. They work both onshore and offshore, where they face challenging conditions like inclement weather and isolation on rigs for long periods. To work offshore, engineers need strong math and science skills, teamwork abilities, and stamina to handle travel and 24/7 work in remote environments.
An Overview of Design, Analysis, Construction and Installation of Offshore Pe...Professor Kabir Sadeghi
Offshore structures are used worldwide for a variety of functions and in a variety of water depths, and environments. Since right selection of equipment, types of
platforms and method of drilling and also right planning, design, fabrication, transportation, installation and commissioning of petroleum platforms, considering
the water depth and environment conditions are very important, this paper will present a general overview of these aspects. This paper reviews the fundamentals
behind all types of offshore structures (fixed or floating) and, in the case of fixed platforms, will cover applications of these principles. The overall objective is to provide a general understanding of different stages of design, construction, loadout, transportation and installation of offshore platforms. Finally, for different sea-water
depths, in which the Cyprus platforms are intended to be installed, suitable kinds of offshore platforms are proposed.

Discuss different conventional hatch including the structural components, testing methods and watertight and weather tight of the hatch cover.
A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold or other lower part of the ship. To make the cargo hold waterproof, most cargo holds have cargo hatch. Hatch covers of ships are designed to be efficient and cost-effective, as an initial investment and during service, and at the same time should suit the demands of the various types of cargo vessels. With the many changing trends of cargo transportation, it would be expected that the design and structure of cargo holds would change to meet the needs of modern shipping. This is clearly evident with container tonnage and the vehicle decks of the Roll-on, Roll-off (Ro-Ro) vessels. However, the changes in the carriage of general cargoes have been comparatively small. This is possible because most merchandise will suit the more popular container or similar unit load movement.
Hold structures have tended to go towards square corners to reduce broken stowage (BS), and suit palletization, pre-slung loads and the use of the fork lift truck inside the holds. Stowage by such vehicles are aided by flush decks in way of the turn of the bilge, as opposed to the angle turn in the sides of the holds of older tonnage.
Some specialist cargoes, like steel coils , still suit conventional holds and clearly would not be compatible inside containers, because of the shape and weight of each item. As with large case goods or castings, which tend to transport better by means of conventional stowage in the more conventional type vessel. Such merchandise is clearly edging towards heavy-lift type loads and these heavier loads are covered in detail here, alongside the designated heavy-lift ship and project cargoes.
The objective of this chapter is to provide an overall picture of an industry sector which is an essential part of cargo handling and general shipping practice. It does not have such a high profile...
Oil and gas industry is changing and moving to deep and ultra deep water which come with new challenges for the current risers design . so i proposed a new design which will change the industry and help drill oil and gas in ultra deep waters
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. Mobile Drilling Platform
Mobile drilling platform is being used in the exploratory drilling, to drill
and to find out if there’s oil and then move on to the next site.
Mostly, the oil company didn’t have the mobile drilling platforms. Since
it is more cost effective to hire expertise and equipment needed than to
keep it under their roof.
The expertise in here refers to the drilling contractor and the service
company like Transocean, Schlumberger, Pride, Frontier, and Sea-Drill.
There are 5 varieties of mobile drilling platforms: drilling barge, jack
up, semi-submersible rig, submersible rig, and drill ships.
5. Drilling Barge
Mostly used in the swamps or coastlines, the drilling
barge has a specification of work about less than 7
meter of water depth.
6. Jack up drilling rig
Jack up oil rigs are limited to shallow water drilling
(typically < 300 feet). A jack up typically has 3 or 4
long legs (up to 350 feet high), each leg is jacked
down to the sea floor until they support the weight of
the entire unit lifting it out of the water. When all
safety checks are complete, and the unit is found
secured, the unit will switch to drilling mode and
begin drilling the well.
(featured video)
7. Submersible Drilling Rig
This drilling platform combines some of the
properties of drilling barges and jack ups. Only in this
case, the production facilities are elevated on stilts
hundreds of feet above pontoon like barges. After
reaching the drill site. The crew floods the barges
with water. The barges sink until they rest on the sea
or lake floor, while the platform remains elevated
above the water on stilts. Like jack-up, this platform
is limited to shallow waters.
8. Semi-Submersibles drilling rig
This unit is called as semi-submersible because once
this unit is over the proposed well drilling
location, they flood their huge ballast tank with the
sea water and partially submerge below surface of the
water.
Semi-submersible will work for 300-2000 ft ocean
depth.
Semi-submersible has the advantage of being very
stable in rough environments, but limited by the
amount of equipment and supplies they are able to
store on board.
9. more with Semi-Submersibles
There are 2 ways on how semi-submersible able maintain its position
over a proposed well, using the anchors and the dynamic positioning
system (DP system).
10. Anchor method
Anchor method is considered as a traditional method of keeping a semi-
submersible on location. Up to 12 anchors are run out away from the unit
and set on ocean floor. The tension in the anchor chain or cable is
increased by using a large winch.
11. Dynamic Positioning System
With a DP system, the semi-submersible uses position information from
GPS system and radio beacons on the ocean floor to constantly monitor
its position. If the DP computer detects that the oil rig is drifting off
location (either caused by the wind, waves, or current), huge thrusters
underneath the rig will apply thrust to push it back over the well.
12. Drill ship
Over the last 15 years, drills hips have been built to
meet the growing demand for highly capable ultra-
deepwater drilling rigs.
Today’s generation of deepwater drill ships use the
DP system for maintaining its position.
Drill ship is capable of working for extended periods
without the need for constant resupplying (larger
storage capacity than semi-submersible).
Other benefit of drill ship is their speed and
maneuverability, drill ship can secure their operation
and sail out of harms way like hurricane.
16. About Offshore Engineers
Offshore oil and gas engineers play a critical role in all facets of offshore operations.
Their skills are used in designing and constructing platform and subsea
structures, drilling equipment, well head operations, subsea pipelines, production and
transportation operations.
Offshore engineers can branch out into many specialties including: drilling and
completions, robotics, marine corrosion, consulting and project
management, pipelines, process control and systems, intervention and tooling, quality
control and inspection, flow assurance, and subsea processes.
Chemical engineering degrees are typically required in process engineers or corrosion
engineers.
17. The working conditions
Offshore oil and gas engineers work in both onshore and offshore locations. While
onshore, they perform their work in an office setting. Trips by helicopter to offshore
platforms and or vessels can occur frequently, so be prepared by it. Accommodation
and meals are provided, workers maybe exposed to inclement weather and potentially
hazardous conditions; however safety protocols are strictly adhered to in order to avoid
any risk. Periods of stay out at sea will vary depending on the project assignment.
18. Some criteria needed in becoming an
offshore engineer
It takes a very unique person set to be able to survive and thrive in the offshore
world, this are some criteria mentioned in careersinoilandgas.com
• Good at math, sciences, and technology
• Consider yourself at a great team-player, able to easily build personal and
professional relationships.
• Have the stamina and enthusiasm to work on ships, platforms, and other unique
offshore work environments.
• Can handle traveling for long periods.
• Comfortable working 24/7 in a relatively isolated environment, with harsh weather
conditions.
• Think a career as an offshore engineer is exciting.
