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.

Offshore drilling technology


First drilling rig type

Colonel Drake
Titusville, USA, 1859
The ‘inventor’ of rotary
drilling for petroleum
exploitation.


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 ensur ....etc

STATCOM-controlled HVDC Power Transmission for Large
Offshore Wind Farms: Engineering Issues
Abstract –
The paper considers a solution for integration of
large offshore DFIG-based wind farms with a common collection
bus controlled by a STATCOM into the main onshore grid
using line-commutated HVDC connection. A design procedure
is described and the controlled system is validated using
PSCAD/EMTDC simulations confirming high performance of
the proposed control strategy in both normal operation conditions
and faults. Engineeri ....etc

VOLTAGE SOURCE CONVERTER TOPOLOGY FOR HVDC GRID CONNECTION OF OFFSHORE WIND FARMS
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 p ....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).
