The Overturning Stability Of A Jack Up Mobile Offshore Production Unit

Even though the probability of failure of stub axle is higher due to impact failure of weld joints. Which may cause the serious safety effect.

“The Boat” by Nam Le, is a serious of short stories that while representing a number of different themes throughout each story, the central theme regards the complicated relationship between children and their parents, with each story examining this theme in different ways. The opening and closing stories, “Love and Honour and Pity and Pride and Compassion and Sacrifice”, and “The Boat”, not only develop the relationship between children and parents and how the child attempts to maintain this relationship; but also how they live their lives without their parents.

Because of the his brilliant idea, he broke “all the standard rules of the day” in its design by using steel to replace wood to build the water tower. He explained to use the eight column were better preference to four, as it can bring the task placed upon the metal of the tank shell to transmit the loads to the post well within the limits which existing structures have shown to be safe. The height and capacity of the water tower were monumental at that time, nevertheless they were considered the requirement for a thriving

The tensile testing was done on the three composite specimens (90°, and two 45°) were completed with a servo-hydraulic load frame with a wedge. The one in the lab was the MTS 647 hydraulic wedge grip and an 810 material test system. The specimens had strain gages with a Wheatstone bridge to collect data such as time, distance, load, axial strain, and transverse strain. From the strain gages, evidence can support how and when the specimen material failed under the stress being applied to it. The test was run for three times on three different specimens. The first specimen that was tested in the hydraulic load was the 0°/90° specimen, which is made of carbon and epoxy laminate composite.

Suspension bridges usually experience torsional forces during very windy conditions where there are high wind speeds, this can create a twisting force causing the deck to rotate resulting in the bridge experiencing shear stress. (Bagga

If your boat will remain in the water, make sure your lines are secured high. You need to account for storm and tidal surges. Make sure your lines are doubled up.

New technology continued to develop including rotary rigs that replaced pile drivers. Texaco and Shell then established “barge drilling,” which was the process of towing small mobile platforms to new locations at the end of drilling jobs (CITE). This resulted in the adaptation of land-drilling methods in the continental shelf in the Gulf of Mexico, as the oil companies continued to grow more confident operating offshore.

Two piers of St. George Island Bridge which are different in the characteristics of the structure, substructure, and in the classification of soil layers, are selected to simulate the barge-pier collision in LS-DYNA. Figure 2(a) shows the elevation view of the St. George Island Bridge in which the location of piers 1 and 3 in the south side of the navigation channel, water level, and the sea bed elevation are presented. Also, Figures 2(b) and (c) demonstrate the dimensions and the elevation of the impact zone, water level, sea bed (mud-line) level, and the soil layers related to piers 1 and 3, respectively. The water level in the location of the Pier-1 is 2.74m above the piles’ cap surface level and the sea bed level is at the same level of

We choose design #1 because the truss bridge is a bridge whose load bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The stressed from tension, and compression helps carry heavier masses. We chose the truss bridge, for it is a very rigid structure and it transfers the load from a single point to a much wider area. A truss is an arrangement of structural members that are connected together to form a rigid frame work. Modern trusses are made of structural steel. All bridges have 4 main characteristics: form, span, material, and travel surface in relation to the structure. A truss bridge is one form that a bridge can take and there are at least 30 different kinds of truss

During the construction, two half-spans being assembled 50 meters above ground level had a misalignment of 4.5 inches or 114mm in camber. It was suggested by John Holland & Constructions to use a kentledge to weigh down the higher section of bridge. It so happened that they had ten, eight tonne concrete blocks on site. These were placed halfway along the higher span to

The issue of whether offshore oil drilling is a safe operation or not has been arguing for a long time in the United States. ( SPE International, N.D.) Drilling on water started in early 1930s in Louisiana by shallow-draft barges. Nevertheless, the first oil well on water was drilled in 9th of September, 1947 by Kerr-McGee’s unit Tender Assist Drilling (TAD) in the Gulf of Mexico (SPE International, N.D.). A year after year, oil companies used more and more sophisticated equipment to drill on water, but the number of spilled accidents has been rising since 1964 (Ivanovich, and Hays, 2008). After all, while

Boats come in many different shapes and sizes. Though they can be fun toys, there is a lot that to consider when diving into the physics behind it. There many factors that need to be taken into consideration when building a boat, a few of the important ones are weight, rudders, the position of a rudder and the position in which a motor is placed. Each of these factors are what either make or break a boat.

For the past few years, I directed my research towered development of mechanical systems and devices for oil and gas industries. The research involve modeling the downhole assembly and fabricating systems/setups and mechanisms to imitate deep drilling (high temperature and high pressure drilling

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.
