1 NDP Annual Report 2014 February 2015

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.

Pilot project: (Nov 2014-Jan2015; Sigmund Jensen & Martin Hovland) Ecology of Lophelia reefs off mid and northern Norway There are microbes in gills of associated mussels! Do they play a role in feeding the mussel & associated corals? How? Operational knowledge: Distribution, sensitivities/exposure to drill cuttings (effects), monitoring (of health status) Workshop (4 th February 2015): Draft comprehensive proposal that addresses both (1) Basic Knowledge gaps + (2) operational knowledge gaps.

9 Environmental Project (4) Benefit to licences Applicability and efficiency assessment of deepwater remote and in situ monitoring technologies. Knowledge of applicability of models and model input data for oil spill risk assessment and operational follow-up. Provision of data on deep-water populations and communities and how to monitor them. Important part of getting permission to explore and develop licenses is to have thorough understanding to avoid harming marine life.

10 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 significant wave height (m) from NORA10 data for different periods (influence of recent storms)

12 Metocean Project (3) Specific work in 2014: Sea Hindcast (NoSH) 5 years continous ( ) and 17 months severe storms ( ) Deep Water Marine Growth Additional work on development over time and increased importance of hard cold corals NoSH area Surface speed at 10 UTC ROMS 4 km horizontal resolution

13 Metocean Project (4) Benefits to licenses NORA10 wind and wave hindcast: The database contains high quality 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. Current Verification Study: ADCP data collected in the uppermost 50 m is noisy, especially during periods with significant wave height above 3-4 m. It is important to further investigate this in order to give recommendations to improve quality for future measurements programs. Sea Hindcast: The new hindcast for the Sea will together with measurements contribute to give a better understanding of the currents during extreme weather. Long-term ( 30 years) nested ROMS hindcast successfully completed for framed area in 4 km grid. This grid is sufficient to provide good statistics regarding currents and current strenght

14 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.

15 Riser and Mooring Project (2) Specific work in 2014 Implementation and validation of novel geotechnical model for pipe-soil interaction in riser analysis software. Mechanical design and qualification work of new riser fairing designs. Advanced analysis of VIV data and development of prediction model for multiriser interaction.

An integrated approach to assess the safety and feasibility of exploration activities and field developments with regards to: Slope stability Drilling problems Geo-hazards

19 Seabed Project (2) Specific work in 2014 Modeling slope stability to arrive at a novel, integrated work flow for soil investigations and landslide hazard assessment, utilising geophysical, geochemical, geological and geotechnical data

20 Seabed Project (3) Specific work in 2014 Technology review and design guidance document for a novel foundation solution for deepwater developments that are designed to slide directly on the seabed Digitisation of analogue sparker records on the shelf to ensure preservation of information Improved understanding of gas ex-solution and sample cracking that has been observed in samples recovered during deepwater geotechnical investigations

21 Seabed Project (4) Benefits to licenses Improved understanding of soil behaviour in deepwater where seabed temperature may be close to zero degrees and samples recovered may suffer disturbance as a result of pressure relief Guidance on novel foundation solution options for deepwater developments Ensuring accessibility of available analogue records in the future and simplification of access through digitisation Cracking of deepwater geotechnical sample Improved, integrated approach which results in better understanding of the environmental processes leading to landslides

22 Subsea Project (1) Objective To develop low cost subsea technology concepts, methods and procedures for installation and operation of subsea systems in deep waters. 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.

23 Subsea Project (2) Environmentally friendly kinetic hydrate inhibitor A new environmentally-friendly Kinetic Hydrate Inhibitor (KHI) from fish waste protein has been developed. This is effective at low temperatures. It can also be added to MEG to reduce the required MEG volume typically up to 50% An operating window for the chemical has been established (including its sensitivity to ph, pressure and synergism with MEG). KHI removal New chemicals have been developed to remove Kinetic Hydrate Inhibitor (KHI) polymers from produced water. They have low toxicity, good biodegradability and show removal efficiencies up to 99% depending on the KHI type. The efficiency of KHI removal on selected green KHI s is not improved by temperature and it is reduced upon the addition of MEG. Fish waste Removal of KHI polymers Untreated KHI polymer in water solution Chemicals Water solution after KHI polymer removal by TC 23

24 Subsea Project (3) Hydrate monitoring Broad-band permittivity sensor systems using open-ended coaxial probes were adapted to Statoil s HP and to SINTEF s rotating pipe rig/cell to measure hydrate formation with gradual build-up of hydrates on the pipe wall. Permittivity sensor measurement system Data shows that formation of hydrate layers as thinner than 1 mm can be detected. In addition, differences in responses with respect to hydrate porosity, water trapped within the hydrate layer, are also detectable 24

25 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 Fish waste into chemicals Removal of KHI polymers Hydrate monitoring 25
