2. System engineering Task ISO/API Define system requirements
Define external interfaces
Define internal interfaces
ISO/API
Different standards are not aligned
Shall -1/17A take this role?
First step is description of external interfaces
Bruk eksempel fra nitrogen precharge for BOP for store dyp

3. External interfaces Physical Functional Operational
To identify when you can not extrapolate earlier experiences is a very important system issue

4. Typical Subsea Production Scenario in the future (E-field and remote operation)
LIGHT WELL
INTERVENTION
SMART WELL INTEGRATION
MODULAR SUBSEA PRODUCTION SYSTEMS
SUBSEA PROCESSING
PRODUCTION TO SHORE
DEEPWATER TRANSPORTATION SYSTEM
LOW COST AND ULTRA DEEP WATER PRODUCTION SYSTEM
DEEPWATER PROCESSING
ULTRA DEEP WATER TECHNOLOGY
LONG DISTANCE TRANSPORTATION AND COMMUNICATION

5. Technology development
The development of technology will have different requirements in different regions. Drivers for these differences are: differences in regulations and environmental conditions different operational practices etc.

6. System Engineering
Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis and system validation while considering the complete problem (INCOSE)

7. Uniform Safety Level. Uniform system integrity requirements
Uniform Safety Level ? Uniform system integrity requirements ?, Uniform design philosophy, common operational criteria ?

The interfaces between subsystem standards and the environment outside the system standard is essential to identify, document and control. It will be a prerequisite to understand the operations or mission of the system in a life cycle perspective in order to properly identify the crucial properties of the interfaces that need to be documented.

10. Interface Management
The objective of interface management is to achieve functional and physical compatibility among all interrelated system elements. The Management and control of interfaces is crucial to successful projects. Interface management is a process to assist in controlling product development when efforts are divided among parties (e. g. customer, contractors, geographically diverse technical teams, etc.) and/or to define and maintain compliance among products that must interoperate.

12. Technical Solution:
Consider the human as a central component when doing logical decomposition and developing design concepts. The User/operators or maintainers will not see the entire system as the designer does, only as the system interfaces with them.

15. Threaded connection fatigue
Bruke eksempel med 20 ganger redusert utmatning når H2S er til stede. Viser betydningen av å forstå applikasjonen

17. Through tubing rotary drilling (TTRD)
TTRD technology in use on fixed platform
Cost savings for subsea wells
Additional well on existing templates: 70 MUSD
Side tracked well: 10 MUSD
Typical example of ”New” operational application of existing designs
The new application willrequire new operation requirements

18. Operational issues Escalating weather, bring riser to secure position:
Installation conditions
Normal operating conditions
Shut in conditions
Hang-off conditions
Difference between intervention tools and permanently installed equipment
Viktig parameter

19. Code of Ethics Necessary? / Old fashion?
What can be learnt from the examples given to day?
How good is industry best practice?
Is earlier experience relevant for this new application?
What are trends we need to consider?
How can we quality assure our designs and the operational use of those to ensure safe operations

20. Openness
Even in an environment with strong competition, openness is worth giving priority. The following issues are essential:
Knowledge is double when shared
Removal of hidden agendas
Mutual respect and trust
Development of attitudes which promote co-operation
Early start of co-operation
