Offshore Service Specification DNV-OSS-401, July 2006Introduction –

INTRODUCTIONThis Service Specification was approved by the Director ofTechnology in July 2006.New technology is generally not adequately covered by estab-lished codes and procedures. New technology must thereforebe qualified by a systematic process where the required func-tionality and reliability is obtained by identifying uncertaintieswhich needs to be reduced through adequate qualificationmethods such as testing and analyses. A guideline for such asystematic qualification process is given by DNV-RP-A203Qualification Procedures for New Technology.

While DNV-RP-A203 provides a general process applicable tothe technology owner and his affiliates, DNV-OSS-401describes DNV’s services based on that process. The objec-tives of introducing the document are to contribute to uniformservice deliveries across the organisation and to serve as a ref-erence document for defining the scope of work in accordancewith the customer’s expectations.

SECTION 1 GENERAL

A. GeneralA 100 Introduction101 This new Offshore Service Specification (OSS) givesguidance on Technology Qualification Management as a serv-ice provided by DNV.

A 200 Objectives201 The objectives of this document are to:

— describe DNV’s Technology Qualification Managementservices for offshore structures and systems

— provide guidance for technology owners and other partiesfor selecting and determining the extent of involvement ofthose carrying out the technology qualification activities

— provide a common communication platform for describ-ing the extent of technology qualification activities.

A 300 Scope of application301 This Offshore Service Specification (OSS) applies toqualification of technology for offshore structures and sys-tems, particularly addressing qualification of new technologywith reference to DNV-RP-A203.302 This OSS applies to technology qualification withingeneral technology development projects as well as qualifica-tion of new technology related to offshore field developmentprojects.303 This OSS describes the necessary activities to be carriedout to obtain DNV statements of feasibility, statement ofendorsement and certificate of fitness for service.

A 400 Structure of this documentThis document consist of three sections and three appendices:

— Section 1 - gives the general scope of the document, back-ground information, definitions and references.

— Section 2 - gives an overview of DNV’s general technol-ogy qualification process which is further detailed inDNV-RP-A203.

— Section 3 - describes DNV’s services related to DNV-RP-A203; describes the deliverables from these services andprovides guidance for selection of the scope of work.

— Appendix A - provides examples of DNV qualificationstatements.

— Appendix B - provides a table that can be used as a basisfor contractual specification of scope of work.

— Appendix C - provides a project start-up check list to sup-port the DNV project management in establishing goodcommunication lines with the client.

B. BackgroundB 100 Introduction 101 Technology qualification is in this document defined as:“the process of providing the evidence that the technology willfunction reliably within specified operational limits with anacceptable level of confidence”. DNV’s technology qualifica-tion services thus differ from DNV’s third party services (asclassification, certification and verification), which are to con-firm that the technology is documented in compliance withspecified codes and procedures.102 New technology is generally not adequately covered byestablished codes and procedures. New technology must there-

fore be qualified by following a systematic process where therequired functionality and reliability is obtained by identifyinguncertainties, which need to be reduced through adequate qual-ification methods, such as testing and analyses. A guideline forsuch a systematic qualification process is given by DNV-RP-A203.103 While DNV-RP-A203 provides a general process appli-cable to the technology owner and his affiliates, this documentdescribes DNV’s services based on that process. These serv-ices are here divided into three groups:

— Technology qualification management.— Fitness for service verification.— Qualification executions.

104 Technology qualification according to this document,and the work process as described in DNV-RP-A203 may con-stitute a necessary part of product certification, (see guidancenote) when the technology or parts thereof is unproven and/ornot adequately covered by established codes and procedures.

Guidance note:Product certification is used above as a general term to denoteindependent verification of a final product versus establishedcodes and procedure, which is affirmed either by a type approvalcertificate or by a project specific statement or certificate. Whenthe technology (or part thereof) is unproven, and hence not fullycovered by established codes and procedures, then the basis forproduct certification may be complemented by technology qual-ification of the unproven parts.

C. DefinitionsC 100 General101 The definitions in DNV-RP-A203 also apply to this doc-ument.

C 200 Verbal forms201 The terms will, can and may are used when describingDNV’s actions or activities, and the terms shall, should andmay are used when referring to other parties than DNV.202 “Shall”: Indicates requirements strictly to be followedin order to conform to this OSS and from which no deviationis permitted. 203 “Should”: Indicates that among several possibilities,one is recommended as particularly suitable, without mention-ing or excluding others, or that a certain course of action is pre-ferred but not necessarily required. Other possibilities may beapplied subject to agreement.204 “Will”: Indicates a mandatory action or activity to beundertaken by DNV. (Ref. “shall” for other parties.)205 “Can”: Indicates an action or activity that DNV will notnecessarily do unless specifically requested by the client. (Ref.“should” for other parties.)206 “May”: Verbal form used to indicate a course of actionpermissible within the limits of the OSS.

C 300 Definitions301 Client: DNV’s contractual partner. It may be the pur-chaser, the owner or the contractor. 302 Conceptually feasible: A technology at an early stage of

DET NORSKE VERITAS

Offshore Service Specification DNV-OSS-401, July 2006 – Sec.1

development is considered conceptually feasible if the mainchallenges have been identified and judged to be resolvable byuse of sound engineering practice.

Guidance note:Although a technology has been stated conceptually feasible,there are still activities necessary to be executed in order provethat the technology is fit for service. Consequently, there will bea possibility that the technology contrary to expectations will notbe stated fit for service.


303 Fit for service: A technology is considered fit for servicewhen the failure modes that have been identified through thesystematic process outlined in this OSS have been properlyaddressed, and the supporting evidence substantiates that thetechnology fulfils all stated functional requirements and meetsthe stated reliability target.

Guidance note:Although a technology has been stated fit for service, the tech-nology has not necessarily an in-service record that eliminatesthe possibility for failures due to unidentified or misjudged fail-ure modes. Consequently, there will be a possibility that the tech-nology contrary to expectations will fail in-service.


304 Hazard: A deviation (departure from the design andoperating intention) that could cause damage, injury or otherform of loss (Chemical Industries Association HAZOPGuide).305 HAZID (HAZard IDentification): A structured reviewtechnique with the purpose of identifying all significant haz-ards associated with the particular activity or operation underconsideration.306 New technology: Technology that is not proven. Thisimplies that the application of proven technology in a newenvironment or an unproven technology in a known environ-ment, are both new technology. The degree of new technologywill be classified in categories to be used as input to riskassessment.307 Probability of success: The probability of completing aqualification activity or a set of qualification activities withinavailable time and with a successful result.308 Proven technology: In the field, proven technology hasa documented track record for a defined environment. Suchdocumentation shall provide confidence in the technologyfrom practical operations, with respect to the ability of the

technology to meet the specified requirements.309 Risk: The qualitative or quantitative likelihood of anaccident or unplanned event occurring, considered in conjunc-tion with the potential consequences of such a failure. In quan-titative terms, risk is the quantified probability of a definedfailure mode times its quantified consequence.310 Risk reduction measures: Those measures taken toreduce the risks to the operation of the technology and to thehealth and safety of personnel associated with it or in its vicin-ity by:

— reduction in the probability of failure— mitigation of the consequences of failure.

311 Statement of endorsement: A document issued by DNVaffirming that, at the time of assessment, it has been found thatthe new technology can be proven fit for service through theremaining planned qualification activities.312 Statement of feasibility: A document issued by DNVaffirming that, at the time of assessment, the new technology isconsidered conceptually feasible and suited for further devel-opment and qualification according to the principles outlinedin DNV-RP-A203.313 Certificate of fitness for service: A document issued byDNV affirming that, at the time of assessment, the new tech-nology is considered fit for service.314 Technology qualification: A confirmation by examina-tion and provision of evidence that the new technology meetsthe specified requirements for the intended use. Hence, quali-fication is a documented set of activities to prove that the tech-nology is fit for service.315 Verification: An examination to confirm that an activity,a product or a service is in accordance with specified require-ments.

SECTION 2 PRINCIPLES OF TECHNOLOGY QUALIFICATION

A. GeneralA 100 Objective101 The objective of this section is to give a brief overviewof the principles of DNV’s Technology Qualification workprocess for new technology as a background for understandingDNV’s qualification management services as described inSec.3.102 A thorough guidance regarding the application of thework process is given in DNV-RP-A203.

B. The Qualification ProcessB 100 General101 Qualification of new technology is a systematic processconsisting of various steps:

— definition of qualification basis— technology assessment— failure mode identification and risk ranking— concept improvement— selection of qualification methods— evaluation of the probability of success (PoS)— data collection (analysis and testing)— functionality assessment.

For further guidance refer to DNV-RP-A203.

B 200 Definition of qualification basis201 The purpose of the qualification basis is, in the absenceof relevant codes and procedures, to define the expectations ofthe technology. Through further qualification processes theseexpectations shall be proven to be fulfilled.202 The qualification basis should include the following keyelements:

— description of the technology to be qualified including sys-tem boundaries and operational limitations

— functional requirements— reliability targets related to safety as well as functional

performance.

B 300 Technology assessment301 The purpose of the technology assessment is to dividethe technology into manageable elements in order to assessthose elements that involve aspects of new technology andidentify the key challenges and uncertainties.302 The technology assessment shall include the followingissues:

— division of the technology into manageable elements(see 303)

— assessment of the technology elements with respect tonewness (see 304)

— identification of the main challenges and uncertaintiesrelated to the new technology aspects (see 305).

303 The technology division shall be achieved by dividingthe technology into one or more of the following types of ele-ments, as relevant:

— sub-systems and components with functions— process sequences or operations— project execution phases based on procedures for manu-

facturing, installation and operation.

304 The degree of novelty of the technology shall be deter-mined by classifying the technology elements with respect toapplication area and technology maturity. Elements classifiedas new technology shall be subject to the further assessment.305 The main challenges and uncertainties related to the newtechnology aspects shall be identified. For complex systems itis recommended that the main challenges and uncertainties areidentified by carrying out a high level HAZID (HAZard IDen-tification).

Guidance note:A high level HAZID is a means of obtaining a better understand-ing of a system at an early stage, and to identify which parts ofthe system that need to be further developed and/or documentedin more detail, prior to the failure mode identification and riskranking.


B 400 Failure mode identification and risk ranking401 The objective of this step is to identify all relevant fail-ure modes of concern for the elements defined as new technol-ogy in the technology assessment and, for each, judge theassociated risks.402 Prior to the identification of failure modes variousclasses of probability and classes reflecting the consequenceseverity shall be qualitatively defined. Based on these defini-tions a risk matrix shall be defined showing fully acceptablecombinations (“low risk”) and unacceptable combinations(“high risk”) as well as intermediate combinations (“mediumrisk”) of probability and consequence classes.403 All relevant failure modes shall be assigned a probabil-ity class and consequence class based on documented reliabil-ity or expert judgements. In the latter case uncertainties shallbe reflected by selecting conservative classes.404 For relatively complex systems the failure mode identi-fication and risk ranking process is recommended to be carriedout as workshops, involving a panel of experts covering thenecessary fields of competences and experiences.

B 500 Concept improvement501 The objective of the concept improvement step is toimplement improvements that have been found necessary orbeneficial during the failure mode identification and risk rank-ing. 502 Improvements would normally imply that the previoussteps in the qualification process need to be updated.

B 600 Selection of qualification methods601 The objective of this step is to select qualification meth-ods that adequately address the identified failure modes of con-cern with respect to reduction of uncertainties anddocumentation of sufficient margins of failure.602 The qualification methods will, in most cases, includetechnical analyses, testing or combinations of the two wherethe purpose of the testing is to reduce uncertainty in the analy-sis model or calibrate it. They may also involve collection ofavailable reliability data and making procedural precautions toavoid the associated problem.603 The selected qualification methods will be input to atechnology qualification plan (TQP) where the various issueswill be outlined as qualification activities needed to be exe-cuted.

DET NORSKE VERITAS


B 700 Evaluation of the probability of success701 The objective of this step is to give a good indication ofthe probability of completing the remaining qualification pro-gram successfully. This is intended to give a basis for the deci-sion to proceed with the analysis and testing phase.702 The evaluation will normally be a judgement of the like-lihood of each individual activity in the qualification plan togive a successful outcome taking the technical challenges andavailable time into consideration. When given as a quantitativeestimate, this is referred to as the probability of success (PoS).An overall PoS for all activities may also be made, and eco-nomical considerations may be included when agreed with theclient.

B 800 Data collection (analyses and testing)801 The objective of the data collection phase is to carry outall the qualification activities prescribed in the TQP.802 If a reliability target is stated in the qualification basis,then an adequate reliability analysis shall be carried out takingthe new information from the data collection into account.

B 900 Functionality assessment901 The objective of this phase is to confirm that the func-tional requirements and target reliability as stated in the quali-fication basis are met.902 This shall be done by confirming that the qualificationactivities have been carried out, and that the acceptance criteriafor the analyses and testing have been met.

SECTION 3 SERVICE OVERVIEW

A. General

A 100 Objectives101 The objectives of this section are to:

— give an overview of the various types of tasks that are partof DNV’s qualification management and fitness for serv-ice verification services

— give guidance on the selection of relevant scope of workfor qualification of new technology.

A 200 Introduction to DNV’s services201 DNV’s possible roles in the qualification process maybe divided into three categories:

— qualification management— fitness for service verification— qualification execution.

202 Qualification management is a service where DNVassists the client in the facilitation of the qualification processdescribed in Sec.2. This implies that DNV carries out a sub-stantial part of making plans, preparing and chairing workshops, proposing methods for uncertainty reductions and doc-umentation of the process.203 Fitness for service verification involves being anobserver to the qualification process described in Sec.2 as wellas verifying technical documentation and witness tests to anextent necessary to issue the DNV qualification statements.204 Fitness for service verification shall not be carried out ontechnology where DNV has ownership or has commercialinterests in any way other than being compensated for thevalue of the provided service.205 Qualification execution comprises the types of workneeded to create the various types of information, such as:

— providing technical expertise in failure mode identifica-tion and risk ranking

— technical analyses and studies— laboratory testing— development of models for failure mechanisms— development of plans and specifications for analyses and

testing to be carried out by DNV or others— risk and reliability analyses.

A 300 Combined roles in the qualification process301 DNV may, as a fully independent company, provideservices where any of the roles defined in A200 are combinedto maximise the value of the services to the Client withoutthreatening DNV’s integrity.302 When qualification execution tasks are provided in com-bination with fitness for service verification different person-nel will be used in the different roles in order to maintain theintegrity of DNV as an independent verifier. Further, the veri-fier shall be involved during the whole qualification executionprocess in order to proactively comment on issues before theybecome irrevocable.

A 400 Combined roles in the qualification process401 Technology Qualification Services may be executed asan integral part of product pertification, see Sec.1 B104 withguidance note.

B. Qualification ManagementB 100 Definition of qualification basis101 The qualification basis may be development predomi-nantly by DNV or written by the client and reviewed by DNV.102 Input for the qualification basis may include designbasis or functional specification, which includes a descriptionof the following items as relevant, but not limited to:

— general system description— functional limitations and main data— authority requirements— main principles for storage, transportation, installation,

commissioning, operation and maintenance as well asabandonment

— interfacing system requirements— environment— functional loads— main principles for manufacturing and quality assurance— reliability targets— health, safety and environment (HSE) requirements.

B 200 Technology assessment201 The technology assessment may be carried out by DNVwith input from and comments by the client or be carried outby the client and commented by DNV.202 The input for the technology assessment shall be thequalification basis with supporting documents as listed below(but not limited to):

— detailed drawings of items subject to qualification— drawings and description of control and safety systems— material specifications— outline fabrication procedure(s)— outline installation procedure(s)— outline inspection and maintenance procedure(s).

203 The technology assessment shall include the main taskslisted in Sec.2 B300.

B 300 Failure mode identification and risk ranking301 The failure mode identification and risk ranking processshould be managed by DNV in cooperation with the client.This involves:

— general preparations for the process— determination of probability and consequence classes and

defining the risk matrix— arrange failure mode assessment involving relevant exper-

tise— report the failure mode assessment.

302 The failure mode assessment should normally be con-ducted as workshops to be planned, chaired and reported byDNV. However, for simple systems and components the fail-ure mode assessment may be carried out more rationally by in-office work where input and comments from the relevantexpertise is achieved by circulation of the records.

B 400 Concept improvement401 When specified by the Client, DNV will call attention toidentified areas for possible improvements or risk reductionmeasures.

B 500 Selection of qualification methods501 The selection of qualification methods may involve

DET NORSKE VERITAS


descriptions of the methods of qualification at different levelsof detail depending on the purpose of the assessment.502 In this context a brief description of the qualificationmethods implies a minimum level of details necessary to serveas a basis for the PoS evaluation and for later development ofdetailed descriptions of the qualification methods. In particu-lar, this implies that the means and purpose of the data collec-tion must be described unambiguously.503 In this context a detailed description of the qualificationmethods implies that the data collection is described at a pro-cedure level necessary to carry out the activities and obtain sat-isfactory results.

B 600 Success evaluation601 The success evaluation may be carried out at variouslevels of sophistication depending on the client's needs forinformation into their own decision process and accessibilityto input parameters. 602 The evaluation will normally be assessed on a qualita-tive basis with respect to technical challenges and availabletime to qualification. When given as a quantitative estimate,this is referred to as the PoS.603 A more sophisticated and informative assessment of thetotal PoS for the whole qualification may be carried out inorder to give the PoS as function of time. The assessmentrequires that a qualification execution plan, that includes allqualification activities, is prepared and that both the probabil-ity of a successful outcome for each activity, and the uncer-tainty in the durations are estimated.604 An economic assessment of the qualification activitiesmay be carried out following the same principles, where thetime parameter is replaced by costs. This requires that cost esti-mates with uncertainties are estimated for each qualificationactivity.

B 700 Data collection (analyses and testing)701 The data collection shall be carried out by the client and/or the client’s subcontractor unless subcontracted to DNV asqualification execution (see D).702 For the purpose of issuing a DNV certificate of fitnessfor service it is required that DNV is involved in the data col-lection phase to an extent necessary to testify that the analysesand tests have been executed according to the technology qual-ification plan and that results are derived and reported cor-rectly. This involvement shall be agreed upon in eachindividual case.

B 800 Functionality assessment801 For the purpose of issuing a DNV certificate of fitnessfor service, DNV shall review and evaluate the functionalityassessment against the qualification basis, to confirm that com-pliance with the functional requirements and reliability targetshas been adequately documented.

C. Fitness for Service VerificationC 100 General101 The objective of the fitness for service verification is totestify that the technology qualification process has been exe-cuted in accordance with this OSS and the principles outlinedin DNV-RP-A203. Additionally, that the functional require-ments and reliability targets as stated in the qualification basishave been adequately addressed, as relevant, at the given stageof the qualification process.102 The fitness for service verification may be carried out asa separate service or integrated with qualification manage-ment.

103 When carried out as a separate service DNV may carryout the fitness for service verification in parallel with the cli-ent’s qualification process. As a minimum, DNV shall takepart in the failure mode and risk ranking process or compensatefor DNV’s absence by alternative arrangements. 104 DNV may on this basis issue statements as outlined inE400.

D. Qualification ExecutionD 100 General101 Qualification execution comprises the type of workneeded to create the various types of information required intothe qualification process. The services may include

— participation in failure mode identification and risk rank-ing with technical expertise

— technical analyses and studies— development of models for failure mechanisms— development of plans and specifications for analyses and

testing — testing— risk and reliability analyses.

E. Service DeliverablesE 100 General101 The main DNV deliverables are shown schematically inFigure 1. The deliverables can be seen in relation to typicalmilestones in offshore field development projects, whereinformation from the qualification of new technology processis needed as an basis for decisions (“decision gates”), as sche-matically illustrated in Figure 2. It is shown that the milestonesfor the qualification process may depend on whether the newtechnology is regarded as an alternative to an available quali-fied technology or the feasibility of the development project isdependant on the new technology to be qualified.

E 200 Milestones in the qualification process201 The milestones in the qualification process are:

TA - Finalisation of the technology assessment.TQP - Completion of the technology qualification plan.TQ - Technology qualified.

E 300 Qualification management – DNV reports301 At each of the milestones the qualification managementservice leads to the following DNV reports, unless agreed oth-erwise:

At TA - Technology assessment report.At TQP - Technology qualification plan.At TQ - Technology qualification report.

E 400 Fitness for service verification – DNV statements and certificates401 Fitness for service verification may lead to the followingstatements and certificates (see Figure 2) based on the criteriagiven in 402 to 405:

At TA - Statement of feasibility.At TQP - Statement of endorsement.At TQ - Certificate of fitness for service.Layouts of these statements are shown in App.A.402 The statements in 401 shall be based on the respectivereports listed in 301 or similar report(s). 403 Following a technology assessment, a statement of fea-

DET NORSKE VERITAS


sibility can be issued provided that the new technology is con-sidered conceptually feasible (see definition in Sec.1 C311),and thereby suited for further development and qualificationaccording to the principles outlined in DNV-RP-A203.

Guidance note:There is an established practice by classification societies, in par-ticular within the maritime industry, to issue a certificate titled“Approval in Principle”. An “Approval in Principle” may beissued as equivalent to a “Statement of Feasibility” when prop-erly referring to this OSS.


404 At the TQP milestone, a statement of endorsement isissued provided that it is found that the new technology can beproven fit for service (see definition in Sec.1 C303) throughthe remaining planned qualification activities.405 At the TQ milestone, a certificate of fitness for service isissued provided that the new technology is considered fit forservice (see definition in Sec.1 C303).

F. Determination of Scope of Work

F 100 Introduction101 The extent of involvement by DNV in the various activ-ities within qualification management and fitness for serviceverification may vary depending on the complexity of the tech-nology, the maturity of the concept and the client’s needs forinformation into their own processes. Various activities havebeen described in order to form a basis for selection of servicesto be included in DNV’s scope-of-work for a particularproject. The services are tabulated in App. B as a form forselection of services.102 In order for DNV to provide services in line with the cli-ent’s needs good lines of communication need to be estab-lished at start-up of the project. A check list intended to be usedat project start-up is given in App. C, to aid in this process.
