An offshore platform is a large structure used to house workers and machinery needed to drill and/or produce natural resources through tunnels/wells in the ocean bed. There are several types of offshore platforms including fixed platforms, compliant towers, semi-submersible platforms, jack-up platforms, and drillships. Fixed platforms can be steel jacket structures anchored to the seabed or large concrete structures that sit on the seabed through their massive weight. Semi-submersible platforms float but have large pontoons to keep them stable, while jack-up platforms have legs that can be lowered to the seabed to raise the drilling structure above water.
Offshore petroleum production has evolved from early onshore operations using wooden derricks to modern floating production systems. Initially, platforms were fixed structures on shallow continental shelves, using steel jacket designs. As water depths increased, new designs like compliant towers and tension leg platforms were developed. Today, the most common systems are semi-submersibles, spars, and ship-shaped floating production, storage, and offloading vessels (FPSOs), which are moored but move with ocean currents and waves. Designing integrated systems that account for environmental loads on the hull, mooring lines, risers, and subsea infrastructure is challenging and expensive, but continues to push into deeper waters and harsher environments to meet global energy demand

Drilling time is reduced by an average of 37 seconds for biotite granite when using a chisel bit and 30 seconds when using a button bit.
The document discusses offshore oil exploration and drilling operations. It begins by explaining how oil is formed from ancient organic matter over millions of years. Geologists use seismic surveys to locate potential oil reservoirs by interpreting reflections of shock waves. If oil is found, exploratory wells are drilled to determine commercial viability. If productive, production wells are drilled and pipelines transport oil to refineries. Drilling rigs are then set up and drilling occurs in stages, with casing installed and cemented between each new section. Wells are logged, tested and completed to allow controlled oil flow up the wellbore.
This document provides an overview of drilling engineering. It discusses the history of drilling beginning in the 1840s using percussion drilling. It describes how rotary drilling was developed to allow for offshore drilling. The document outlines the infrastructure and processes involved in drilling, including offshore and onshore structures, load considerations, drilling rigs, bits, pipes, fluids, cementing, directional drilling, kicks, blowout preventers, completions, wellheads, manifolds, and abandonment. Key aspects driving infrastructure decisions are the economic viability and technical requirements of the reservoir and installation.

3) Specific projects discussed include the ROAZ and RODI sites in Agartala, Tripura where civil works estimated at Rs. 1.89 crore and Rs. 3.20 crore were carried out such as earthworks, concrete works, road works, sheds, tubewells, and reservoirs.
1) The document summarizes current approaches to seismic design and analysis of underground structures like tunnels. It describes how ground deformations from earthquakes are estimated and transmitted to underground structures.
2) Analysis methods include ignoring structure-ground interaction, pseudo-static analysis that imposes ground deformations as static loads, and dynamic analysis using tools like finite element modeling.
3) Recent earthquakes showed underground structures generally suffer less damage than surface structures. However, some underground structures experienced significant damage, like the 1995 collapse of the Daikai subway station in Kobe, Japan, where relative displacement between structure levels exceeded design.
This document provides an overview of tunnels, including their definition, history, construction methods, design considerations, and effects of earthquakes. Tunnels are underground passages constructed for various purposes like transportation. Key construction methods include cut-and-cover, drill-and-blast, bored tunneling using a Tunnel Boring Machine, and sequential excavation. Design requires considering factors like ground conditions, water management, tunnel usage, and seismic activity. During earthquakes, tunnels can experience ground shaking, ground failures, deformations, cracking, and other effects that must be addressed in seismic design. The Gotthard Base Tunnel case study exemplifies addressing geological challenges during tunnel construction.
Civil engineering Seminar on G cans project japan.Mayur Rahangdale
The G-Cans project is a massive underground flood diversion system that protects Tokyo, Japan from flooding. It consists of five 65m tall concrete silos connected by 6.3km of tunnels 50m underground. Flood water is channeled into the silos and tunnels from rivers around Tokyo and stored in an underground storage tank before being pumped at a rate of 200 tons per second into the Edo River. The $3 billion project was completed in 2006 and has been used over 200 times to prevent flooding, saving an estimated $430 million in property damage.
The document provides an introduction and overview of offshore oil drilling operations. It discusses the reasons for offshore drilling given increasing global oil demand.

(1) Hyatt Regency Walkway Collapse :-
On July 17, 1981, the Hyatt Regency Hotel in kansas City, Missouri, held a videotaped tea-dance
party in their atrium lobby. With many party-goers standing and dancing on the suspended
walkways, connections supporting the ceiling rods that held up the second and fourth-floor
walkways across the atrium failed, and both walkways collapsed onto the crowded first-floor
atrium below. The fourth-floor walkway collapsed onto the second-floor walkway, while the
offset third-floor walkway remained intact. As the United states\' most devastating structural
failure, in terms of loss of life and injuries, the Kansas City Hyatt Regency walkways collapse
left 114 dead and in excess of 200 injured. In addition, millions of dollars in costs resulted from
the collapse, and thousands of lives were adversely affected.
(2) TV Antenna Collapse. :-
Total collapse during installation of a 6-ton FM antenna being placed on a new 1800 ft. tower. 5
technicians killed, 3 on the hoist and 2 on the tower. It was determined that insufficient sized
bolts on a makeshift lifting lug extension failed. The falling debris severed one of the tower\'s
guy wires, causing the tower to collapse.
The following case is based on an actual incident. However, individual actors and company
names have been changed due to possible pending litigation. In addition, although conversations
and memorandums used are based on evidence surrounding the case, they are hypothetical in
nature, and are used to illustrate important issues rather than to attempt an actual reenactment of
what \"really\" happened.
In 1982, a television station video crew was filming the raising of their new television tower. The
antenna was designed and manufactured by Antenna Engineering, Inc., a moderately-sized local
firm. Riggers, Inc., a small local firm, was contracted to raise and assemble the antenna. During
the initial design, Antenna Engineering submitted antenna plans to Riggers for their approval.
Riggers approved the plans which provided for placement of the antenna hoisting lugs. These
lugs provided attachment points for lifting cables which would be used for removing the antenna
sections from the delivery truck, and for hoisting the antenna into the air for final assembly on a
1000 foot tower. A crew of riggers who had constructed such towers for many years was on-site.
The crew used a vertically-climbing crane mounted on the already constructed portion of the
tower to lift each new section of the tower, and finally, the two-section antenna onto the top of
the tower. The design called for a three-legged tower, and as each new section was lifted, it was
positioned and bolted onto the previous tower sections, one piece at a time. The tower legs were
solid steel bars with 8 inch diameters. The tower sections we.
Oil is formed from ancient organic remains over millions of years. Geologists use techniques like seismic surveys and gravity measurements to locate potential oil reservoirs. Once a promising site is identified, crews prepare the land, set up a drilling rig, and drill a surface hole to the target depth using a rotating drill bit and circulating drilling mud. Modern offshore and onshore drilling is a complex process involving precisely engineered rigs, drilling equipment, and procedures to extract oil from deep underground reservoirs.
Conventional shaft sinking by manual meansSafdar Ali
This document describes the process of conventional shaft sinking through manual means. The key steps are:
1) Preparatory work including site preparation, surveying, and erecting temporary surface structures.
2) Installing sinking equipment such as a headframe, winding engine, buckets, platforms, drills, pumps, and ventilation equipment.
3) Sinking operations proceed in cycles of drilling, blasting, muck removal, and concrete lining installation in 1.2m sections over 240 hours for a monthly progress of about 9m. Subsidiary works like pumping, ventilation and services are also described.
This document provides information about tunnel construction using the New Austrian Tunneling Method (NATM). It discusses the various steps of NATM tunneling including drilling, blasting, mucking, shotcreting, installing lattice girders and rock bolts, and ventilation. NATM is advantageous for tunneling in soft ground as it monitors rock deformation and designs support structures accordingly. The document outlines the typical sequence of NATM tunnel construction and importance of factors like geology and ventilation.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
