Drilling operation How do we do it?
We use energy to break up the rock and create a hole
The energy consists of rotation and hydraulic forces
The energy is optimised by tuning drilling parameters
After drilling a section of the well, it is sealed off
with steel pipe to ensure integrity for the following

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

Abstract

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC gri ....etc

As I was writing a blog content, this question came to my mind what are the benefits of dedicated offshore software development teams?. If you could help give me other ideas it would be of help. I have some ideas but I don't think that it is enough to write a good article for the blog. ....etc

Weather is a major factor in platform operation. When high sea and hurricanes approach a platform the crew must evacuate to prevent injury or loss of life. Thus safety is an important factor as far as an oilrig is concerned. Oil and gas production must continue on an uninterrupted manner to ensure profitability. To further this end, labor-intensive, repetitive task such as opening and closing valves, monitoring levels, and shut down of platform to prevent equipment damage are handed over to programmable logic controllers (PLC's).

Many companies opt to employ the services of other firms from outside their country for a number of reasons. These reasons can either be for lower costs for manpower, greater availability of high quality resources, overcoming constraining employment law, or for reasons as simple getting the right expertise at the right time to complete specified work. ....etc
