Ground investigation in shallow offshore sites

t in situ where the installations are to be located, comprehensive data acquisition is required in the entire area affected and far down beneath the sea floor. Such processes that encompass offshore site investigations are varied in nature. They range from analyzing marine geological information, scrutiny of available geophysical data which is used to plan the actual investigations. Such processes that lead to the success of the above mentioned range consist of drilling, sampling as well as in situ testing which in essence includes penetrating into the seabed with the help of high technology drilling vessels. These processes encompass what is generally referred to as Geotechnical investigation.
From The period 1985 to 1982 Lunne and Powell (1992) gave a review of developments in offshore investigations. They explored the various technological inventions that marked this period and discus the contributions of such developments to offshore studies with new in situ tests being tried out in the offshore environments, including several examples of field model testing. Lunne and Powell observed the general trend over the last 6-8 years which was the gradual increase in deep water developments. Due to the difficulty of taking undisturbed samples in deep water there has been a tendency to rely more on situ testing. Special geotechnical problems associated with geo-hazard evaluations have also inspired developments within the field of in situ testing. In addition the general competitiveness of the market has been a driver cost efficient solutions.
Borings, the most efficient and probably accurate technique of shallow offshore studies come in two main varieties, large-diameter and small-diameter boring. Large-diameter borings Peres involve offshore drilling with large enormous machines that bore extensive areas. They are rarely used due to safety concerns and expense, but are sometimes used to allow a geologist or engineer to visually and manually examine the soil and ...

Pile foundations are chosen for the situations where structures transmit huge loads and suitable soil layer capable of supporting these loads are available only at greater depths. The piles are long and slender members capable of transmitting the loads of the structure into the hard soil layer or the rocks successfully even if very poor or soft soils that are considered to be inferior to meet this purpose is present in the upper layers. Based on the load carrying function piles are classified as end bearing pile, friction pile or combination pile that undertakes both the functions…

are some of the countries where MNCs from USA, UK, Germany and other developed nations have started outsourcing the jobs. This trend has picked up in a big way in the last 15 to 20 years. In fact, as this trend kept growing, a debate also started in the political spheres about the job losses taking place in USA, Germany, UK etc. In the recently concluded Presidential elections in the USA, outsourcing became a big issue, with the candidates spelling out their own versions of the truth on outsourcing by many companies. But as per the indications available the trend appears unstoppable in the…
