Project: Production of electricity at surface and subsea with innovative, unique choke turbine.

The Tool Tech choke turbine is an innovative way to generate electric power from the flowing energy produced by the production wells onboard offshore platforms and subsea. Our invention will recycle energy from wellflow. There are two different market applications;_x000D_A) - Production of electrical power from offshore oil platforms into usable electricity by supplementing the traditional choke valves with our innovative choke turbines in order to reduce greenhouse gas emissions. _x000D_B) - Generation of electrical power on mature subsea installations in order to facilitate the use of available Increased Oil Recovery technology that cannot be implemented today, due to electrical power shortage on older subsea fields. _x000D_ _x000D_ Today, the energy potential of hydrocarbon flow from wells is not exploited. Choke valves on an offshore platform are fitted downstream of the production surface trees, topside on the pipeline and at the subsea X-mas tree. Their critical function is to reduce the flowing pressure generated from wells. Innovative electricity production from the well flow can supplement energy produced with offshore gas powered turbines and thus contribute to a substantial reduction of CO2 and NOx release to the atmosphere from offshore installations. Power consumption onboard a production platform will vary depending on many different factors. Gas or water injection into the reservoir is a major electrical power consumer, and power consumption will increase as the field is depleted and injection increases. A typical electrical power requirement is 16MW for a platform with moderate consumption. In this case, there will typically be installed 2 x 18MW gas turbines onboard (one standby). On older installations, there are often energy-intensive operations, including injection into the reservoir, while supply of fuel gas for operation of the turbines may be inadequate. The Norwegian Draugen platform is an example of this, where they intend to drill new wells for fuelgas production to cope with the problem and extend the life of the field. This is expensive and further increases CO2 and NOx emission. _x000D__x000D_Most fields have well pressure that can be exploited with a choke turbine for conversion of energy into electricity instead of the traditional choke valves that are used for flowing pressure reduction. Our ambition is that the turbine units shall be designed to withstand sand and particles better than valves. Each turbine shall be controlled individually against the upstream pressure. The proposed turbine solution uses gears in order to work at high pressure and achieve high efficiency and good pressure regulation. The turbine unit is typically installed downstream of an existing choke valve that may take some of the pressure drop, depending on the relevant well stream, production control, etc._x000D__x000D_Additional energy provided through generation of electrical energy from the well stream can be an environmental friendly and affordable alternative to cope with fuel gas deficiency compared with other solutions to the problem, like electrification from shore, taking fuel gas from other installations, get gas from new wells, or use other fuels. Reduced emissions through use of the new solution will probably be a major incentive that can pave the way towards broad implementation of the choke turbine technology offshore. _x000D__x000D_The CO objective of the R&D project is to develop a 5.000 psi rated prototype solution that is qualification tested through a pilot project. This will be our first step towards a successful commercialisation of the technology._x000D__x000D_With proven/-qualified technology, there should be a huge potential for this clean energy source, which can be implemented with extremely fast return on investment. Implementation of power from shore on some platforms in Norway indicates that there is a will to reduce offshore CO2 emission, even at great cost. Ref. section 2.2.2.4. However, Increased Oil Recovery (IOR) of subsea wells will, by far, provide the largest economical benefit for the Clients._x000D__x000D_The consortium of business Ps for the Choke Turbine development will form the base for a supply chain providing the technological solutions and capabilities to become a suitable vehicle for post project development, marketing and product support. _x000D__x000D_The French company Euro Techniques Industries (ETI) will be our P and will deliver the electrical power equipment. http://e-t-i.fr/._x000D__x000D_Tool-Tech will retain the IPR of the Choke Turbine system and will upon commercialization of the product get a license fee on the products sales and contribute with personnel resources for engineering and service work as required._x000D_
