3 1. DNV GL Project Goal Goal: Create an improved and less invasive classification scheme for verification of DP systems by enabling the use of modern technology. Technology examples: Self verifying cyber physical systems/build in test equipment (BITE) Remote verification of DP related equipment Use of data-analytics Other Project deliverables: Alternative DP Fleet In Service (FIS) scheme document DP FIS survey methods and tools requirements document Establish internal and external procedures, including procedures for positive reporting 3 06 September 2017

4 2. Expected benefit examples from the new scheme Examples of typical benefits: Increased safety: - Improved level of 3 rd party verification (tailor made verification scope) - Improved Management of Change (MOC) processes (HW & SW) Increased efficiency by means of: - Flexible schemes (less calendar based) - Less invasive verification (reduced need for physical surveyor presence) Examples of possible D-class methods: Automated tasks and verification during operations (reduced down-time) Remote witnessing Use of monitoring and data analytics Build in test equipment (BITE); self-verifying cyber physical systems Intended future synergies: Schemes and methods will be transferable to classification of other systems. D-Class methods and schemes will be prerequisite for autonomous vessels 4 06 September 2017

5 3. Project Set-up (1) Project Sponsor: Project Manager: DP Specialist: Control systems: Marine Cybernetics: Noble Denton: Odd Magne Nesvåg Jan van Tiggelen Aleks Karlsen Karl Hovden Rune Green Steven Gargill Project set-up: Industry Development Project (by DNV GL Class). Industry partners are free to participate in all or selected workshops based on interest or availability. Project participants will get access to a SharePoint information site that will contain relevant project related documentation (papers, minutes, etc.). Non-active interested parties may subscribe to a project information mailing list September 2017

6 3. Project Set-up (2) Participation is open for interested DP related industry partners from different segments (Operators, Owners, Equipment Manufacturers, Research Institutions, Designers and Yards). DNVGL prepares contents, prepares and organizes one day workshops at Veritas 1, Høvik, Oslo. (typical :00 hours). DNVGL covers costs for preparing & organizing workshops; each participant covers own cost. For 2017 four workshops are planned: - WS-1: Oslo Norway, 11 May - WS-2a: Oslo Norway, 5 September - WS-2b: Houston US, 20 September - WS-3: Oslo Norway, 23 November (tentative) Additional project meetings can be arranged with interested parties to discuss specific topics when needed September 2017

7 4. Present scheme Traditional class verification methods and tools Witness on site Manual tasks Physical presence QA System which may cause ESV / HIL FMEA/FMD Interruption of operations Downtime and delays Varying level of verification Low verification efficiency in modern technology and moderns ways of operating vessels On-board survey CMC Plan approval 7

8 5. Future schemes and methods must be gradually implemented Future schemes and methods will enable Self-verifying systems Automated testing Extended simulation Remote survey Not calendar based New classification scheme QA System which can provide Reduced need for physical presence Automated tasks ESV / HIL FMEA/FMD Verification during operations Flexible schemes Improved level of verification Reduced down-time Methods fit for autonomous vessels and digital twins On-board survey Self verification CMC Plan approval 8

9 5. Future schemes - full automatic coverage may not be possible Future schemes and methods will enable Self-verifying systems Automated testing Extended simulation Remote survey Not calendar based New classification scheme QA System which can provide Reduced need for physical presence Automated tasks ESV / HIL FMEA/FMD Verification during operations Flexible schemes Improved level of verification Reduced down-time Methods fit for autonomous vessels and digital twins On-board survey Self verification CMC Plan approval 9

10 5. The class methods may shift - but the role shall be maintained Positive reporting of all results Verify that the result is in accordance with acceptance criteria, in the actual test condition Verification Body Secondary target systems*) Equipment/system under test Verify that the test is applied in the right manner to the equipment/system when in the correct mode *) This is a very important issue. Extended and exploratory testing based on observations is very common. Will the new tools and methods cater also for this? 10

11 5. D-Class project intentions What can change and what not? Can change: 1. Verification methods 2. Surveyor presence on site 3. Test and verification of result not necessarily simultaneous 4. Scheme (not calendar based) 5. Verification scope (improved) Unchanged: 1. Purpose and role of class - independent verification 2. DP system requirements 3. Subsequent adjustment of the FIS rules is not within scope of this project New improved verification scope DP System (old scheme) Verification scope DP System (D-Class scheme) Old verification scope 11

12 6. Conceptual challenges Typical issues that have been identified: Do all parties welcome transparency provided by online verification schemes? How to maintain the genuine 3 rd party verification? Integrity (prevent cheating) Uncertainties concerning new business models? Information security and data leakage (cyber security) Less on board presence of experienced surveyor Less exploratory testing as result of automated methods Industry resistance against change Etc. 12
