1 NDP Annual Report 2013 February 2014

2 NDP - History NDP was established in 1996 when the first deepwater licenses were awarded (15 th Concession Round) in the Sea. New licenses have been awarded in all following concession rounds, the latest 22 nd round licenses awarded in The programme phases are Phase 1 ( ), Phase 2 ( ), Phase 3 ( ), Phase 4 ( ) and Phase 5 ( ). Project investment since the start is approximately NOK 400 millions. Last years budgets have been around NOK 20 millions. NDP covers mainly an area between 62 N and 69 N, from the continental shelf at 400 m water depth to the abyssal plain at approximately 2500 m. In Phase 4 the deepwater slope area west of the Barents Sea was included in NDP. The area comprises therefore all deepwater provinces in waters. Metocean modeling covers a much wider area, from the Atlantic west of Ireland, the North Sea and the Barents Sea. In order to achieve objectives for Phase 5 and the time beyond, a strategy discussion started in A plan for needs and opportunities will be finished early All NDP results are stored in License2Share, the official communication and archiving tool for administrative interaction between operators, partners and authorities for all licenses in waters.

Providing a map of surfacing gas flow rates which are used as input to atmospheric dispersion models for explosion danger analysis. Important part of getting permission to explore and develop licenses having thorough understanding of not harming marine life.

9 Metocean Project (1) Objective To establish metocean conditions and databases for use in deepwater operations and design of installations by: Acquisition of ocean current data Modeling and establishment of hindcast for currents and waves Analysis of remote sensing data and research on ocean dynamics in order to understand the deepwater currents Extreme wind speed (m/s)) from NORA10 data ( )

10 Metocean Project (2) Specific work in 2013: Annual update of NORA10 including validation of results with measurements Monitoring drifting sand waves and currents in m water depths in the Barents Sea and modelling. marine growth and new design recommendation Sea Hindcast (NoSH) 5 years continous ( ) and 17 months severe storms ( ) Sand wave monitoring and modelling

11 Metocean Project (3) Benefits to licenses NORA10 wind and wave hindcast: The database contains wave and wind data in 10 km resolution from West of Ireland to the Arctic for the period 1957 to Data are used for planning purposes of both exploration and field development. Validation studies show that the data base has very high quality. Sand wave project: The sand wave project will provide operators in the Sea with important information on development and propagation on sand waves in deep water in the Sea. Marine Growth: The Marine Growth project will provide operators in the Sea with updated recommendation on marine growth in the Sea. Effect on NORA10 database by last 3 years (Hs for North Sea)

12 Riser and Mooring Project (1) Objective To identify cost-efficient riser and mooring configurations by focusing on critical elements and building on world-wide expertise and experiences with the focus on: Development of new riser solutions for deep water and harsh environments Addressing relevant challenges for mooring and riser design Development of new devices for suppression of vortex induced vibrations Fundamentals for design of deep water riser and mooring systems Being a forum in which technology needs and challenges of the licenses are discussed and exchanged.

To make operators, suppliers and contractors aware of the challenges for future field developments in deep water areas in the Sea. To contribute to improved hydrate control concepts and solutions.

19 Subsea Project (2) Impact of corrosion on hydrate growth Systematic studies were conducted in a transparent pipe at SINTEF to evaluate the impact of corrosion on hydrate plugging. Experiments with corroded and non-corroded steel tubes were completed but the set-up was concluded not to be suitable for the objectives of the study. Environmentally friendly kinetic hydrate inhibitor A set of new environmentally-friendly Kinetic Hydrate Inhibitors (KHI) from fish waste protein has been developed. These are effective at low temperatures. They can also be added to MEG to reduce the required MEG volume Hydrate film on a water bubble. Fish waste into chemicals 19

20 Subsea Project (3) Hydrate monitoring Permittivity sensor systems were adapted to Statoil s HP and to SINTEF s rotating pipe rig/cell to measure hydrate deposition thickness. Experiments were performed in different fluid systems with gradual buildup of hydrates on the pipe wall. Preliminary data shows differences in responses with respect to hydrate layer thickness and porosity. KHI removal Chemicals have been developed to remove Kinetic Hydrate Inhibitor (KHI) polymers from produced water. They have low toxicity and good biodegradability. Different efficiencies have been achieved depending of the KHI type. For standard type of polymers removal efficiencies of >99% have been observed. Permittivity sensor 20 Removal of KHI polymers

21 Subsea Project (4) Benefits to licenses Improved operational guidelines, extended knowledge for hydrate deposition control and use of more environmental friendly chemicals through: Access to a new measurement technology for characterization of hydrate Greener chemicals available for usage Reduced chemical usage More time available for corrective operational measures rather than focusing on hydrate control measures Safer operation 21
