NorwegianDeepwaterProgrammeNDP - History

NDP was established in 1996 when the first deepwater licenses were awarded (15th

Concession Round) in the Norwegian Sea. New licenses have been awarded in all

following concession rounds, the latest 22nd round licenses awarded in 2013.

The programme phases are Phase 1 (1996-2000), Phase 2 (2001-2005), Phase 3

(2006-2008), Phase 4 (2009-2012) and Phase 5 (2013-2016). Project investment since

the start is approximately NOK 400 millions. Last years budgets have been between

NOK 15 and 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 by Eni license PL529. The area comprised therefore all deepwater provinces in Norwegian waters. Metocean modeling covers a much wider area, from the Atlantic west of Ireland, the North Sea and the Barents Sea.

Discussion started in 2015 on when and how to close down NDP following the completion of phase 5 in 2016. It was decided by the JLSC to finalize the work mid 2016 and deliver a close out report at the latest in Q3 2016.

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 Norwegian waters.

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.

NorwegianDeepwaterProgrammeMetocean 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)


Specific work in 2015:

• Annual update of NORA10 including comprehensive validation report

• Established Ocean4cast for distributing NORA10 data

• Desktop study on internal waves, summarizing all earlier efforts on the subject

• Current Verification Study (Curves), studying noise in ADCP data

• Support Svinøy measurements, 20 years with current measurements from 1 location in the Norwegian Sea


Specific work in 2015:

• Norwegian Sea Hindcast (NoSH) – 5 years continous (2008 - 2012) and 17 months severe storms (1993 - 2007), validation report on NoSH hindcast cpompleted

NoSH area

Surface speed 2013-10-07 at 10 UTCROMS – 4 km horizontal resolution


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 2013. 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.

Norwegian Sea Hindcast: The new hindcast for the Norwegian 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

NorwegianDeepwaterProgrammeSeabed Project (1)

Objective

To improve the regional and local understanding of hazards, the geotechnical challenges and other related processes and features on the seabed and in shallow sediments in different environmental settings.

An integrated approach to assess the safety and feasibility of exploration activities and field developments with regards to:

• Slope stability

• Drilling problems

• Geo-hazards


Specific work in 2015

• Deep water core samples have shown “cracks”, which makes it challenging to estimate the “true” in-situ parameters.

• Extensive laboratory testing has concluded that it would be possible to correct for this disturbance by performing SHANSEP testing and combining the results from these tests with in-situ tests.

Seabed Project (2)


Specific work in 2015

• Current engineering practice for modellingwellhead fatigue involves using monotonic soil resistance vs displacement (p-y) curves which are not suitable for dynamic problems.

• It was proposed to carry out full-scale load tests to verify the soil-structure interaction framework developed based on centrifuge testing and numerical modelling. Phase 1 of this work involved pre-engineering of these tests (test set-up, hardware configuration and development of test programme).

Seabed Project (3)

NorwegianDeepwaterProgrammeSeabed Project (4)


• Improved understanding of soil behavior in deepwater, where gas exsolution and cracking in core samples may cause a challenge

• Guidance on how to estimate the true in-situ properties of the soil where cracking or general sample disturbance can be an issue

• Recommendations on improving geotechnical input parameters for modellingwellhead fatigue

• Work ongoing to establish a database for p-y and damping values to be used in wellhead fatigue analyses of conductors.

NorwegianDeepwaterProgrammeSubsea 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 Norwegian Sea.

• To contribute to improved hydrate control concepts and solutions.

Subsea Project (2)

Environmentally friendly kinetic hydrate inhibitor based on fish waste protein

• An extended performance evaluation of the new environmentally-friendly Kinetic Hydrate Inhibitor (KHI) developed during 2015 was conducted. Various operational modes and fluid systems were studied. Results indicate that the KHI has a reliable performance under gas dominated systems and oil dominated systems. It is brine tolerant and mantains its performance during shut-in ad re-start sequences

• The impact of the KHI on the water quality process was investigated. This preliminary evaluation indicates thatg the KHI has minimum impact on the water quality.

Subsea Project (3)

KHI removal, recovery & re-use

• Due to KHI-MEG co-injection, an evaluation of the fouling potential of two selected green KHI at typical MEG-regeneration operating conditions (atmospheric and vacuum) and at pipeline injection temperatures were studied. Tests were conducted on aqueous KHI at selected MEG + Salt concentrations – both at atmospheric and under vacuum conditions. Results indicate that the green KHIs don't precipitate under heating neither at pipeline injection temperatures and that their performance is maintained after the heating process (up to 150°C ).

• Recoveries of 30-50% of green KHIs with selectedtreatment chemical was achieved.

Subsea Project (4)

Hydrate monitoring

• The Broad-band permittivity sensor systems

developed during 2013-2014 were evaluated

on a pilot plan scale in the flow loop at SWRI,

to further optimize/develop the sensors and

to improve the detection of thick deposits

• A correlation between the mechanical probe geometry and the system operating conditions was stablished. Based on this, a modified coaxial probe that can characterize thicker deposit layers, (up to 15mm), was designed

• Preliminary evaluations indicated that a waveguide sensor, has potential to characterize much thicker deposits
