CHANGES

MOTIVESThis Service Specification was approved by the Director of Technology in July 2006.New technology is generally not adequately covered by established codes and procedures. New technologymust therefore be qualified by a systematic process where the required functionality and reliability is obtainedby identifying uncertainties which needs to be reduced through adequate qualification methods such as testingand analyses. A guideline for such a systematic qualification process is given by DNV-RP-A203 QualificationProcedures for New Technology.While DNV-RP-A203 provides a general process applicable to the technology owner and his affiliates, DNV-OSS-401 describes DNV’s services based on that process. The objectives of introducing the document are tocontribute to uniform service deliveries across the organisation and to serve as a reference document fordefining the scope of work in accordance with the customer’s expectations.

GeneralAs of October 2010 all DNV service documents are primarily published electronically.In order to ensure a practical transition from the “print” scheme to the “electronic” scheme, all documentshaving incorporated amendments and corrections more recent than the date of the latest printed issue, have beengiven the date October 2010.An overview of DNV service documents, their update status and historical “amendments and corrections” maybe found through http://www.dnv.com/resources/rules_standards/.

Offshore Service Specification DNV-OSS-401, October 2010 Amended October 2011 – Sec.1 see note on front cover

SECTION 1GENERAL

A. General

A 100 Introduction

101 This new Offshore Service Specification (OSS) gives guidance on Technology QualificationManagement as a service provided by DNV.

A 200 Objectives

201 The objectives of this document are to:

— describe DNV’s Technology Qualification Management services for offshore structures and systems— provide guidance for technology owners and other parties for selecting and determining the extent of

involvement of those carrying out the technology qualification activities— provide a common communication platform for describing the extent of technology qualification activities.

A 300 Scope of application

301 This Offshore Service Specification (OSS) applies to qualification of technology for offshore structuresand systems, particularly addressing qualification of new technology with reference to DNV-RP-A203.

302 This OSS applies to technology qualification within general technology development projects as well asqualification of new technology related to offshore field development projects.

303 This OSS describes the necessary activities to be carried out to obtain DNV statements of feasibility,statement of endorsement and certificate of fitness for service.

A 400 Structure of this document

This document consist of three sections and three appendices:

— Section 1 - gives the general scope of the document, background information, definitions and references.— Section 2 - gives an overview of DNV’s general technology qualification process which is further detailed

in DNV-RP-A203.— Section 3 - describes DNV’s services related to DNV-RP-A203; describes the deliverables from these

services and provides guidance for selection of the scope of work. — Appendix A - provides examples of DNV qualification statements.— Appendix B - provides a table that can be used as a basis for contractual specification of scope of work.— Appendix C - provides a project start-up check list to support the DNV project management in establishing

good communication lines with the client.

B. Background

B 100 Introduction

101 Technology qualification is in this document defined as: “the process of providing the evidence that thetechnology will function reliably within specified operational limits with an acceptable level of confidence”.DNV’s technology qualification services thus differ from DNV’s third party services (as classification,certification and verification), which are to confirm that the technology is documented in compliance withspecified codes and procedures.

102 New technology is generally not adequately covered by established codes and procedures. New technologymust therefore be qualified by following a systematic process where the required functionality and reliability isobtained by identifying uncertainties, which need to be reduced through adequate qualification methods, such astesting and analyses. A guideline for such a systematic qualification process is given by DNV-RP-A203.

103 While DNV-RP-A203 provides a general process applicable to the technology owner and his affiliates,this document describes DNV’s services based on that process. These services are here divided into threegroups:

— 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 constitute a necessary part of product certification, (see guidance note) when the technology or partsthereof is unproven and/or not adequately covered by established codes and procedures.


Amended October 2011 Offshore Service Specification DNV-OSS-401, October 2010see note on front cover Sec.1 –

Guidance note:Product certification is used above as a general term to denote independent verification of a final product versusestablished codes and procedure, which is affirmed either by a type approval certificate or by a project specificstatement or certificate. When the technology (or part thereof) is unproven, and hence not fully covered by establishedcodes and procedures, then the basis for product certification may be complemented by technology qualification ofthe unproven parts.

C. Definitions

C 100 General

101 The definitions in DNV-RP-A203 also apply to this document.

C 200 Verbal forms

201 The terms will, can and may are used when describing DNV’s actions or activities, and the terms shall,should and may are used when referring to other parties than DNV.

202 “Shall”: Indicates requirements strictly to be followed in order to conform to this OSS and from whichno deviation is permitted.

203 “Should”: Indicates that among several possibilities, one is recommended as particularly suitable,without mentioning or excluding others, or that a certain course of action is preferred but not necessarilyrequired. Other possibilities may be applied subject to agreement.

204 “Will”: Indicates a mandatory action or activity to be undertaken by DNV. (Ref. “shall” for otherparties.)

205 “Can”: Indicates an action or activity that DNV will not necessarily do unless specifically requested bythe client. (Ref. “should” for other parties.)

206 “May”: Verbal form used to indicate a course of action permissible within the limits of the OSS.

C 300 Definitions

301 Client: DNV’s contractual partner. It may be the purchaser, the owner or the contractor.

302 Conceptually feasible: A technology at an early stage of development is considered conceptually feasibleif the main challenges have been identified and judged to be resolvable by use of sound engineering practice.

Guidance note:Although a technology has been stated conceptually feasible, there are still activities necessary to be executed in orderprove that the technology is fit for service. Consequently, there will be a possibility that the technology contrary toexpectations will not be stated fit for service.


303 Fit for service: A technology is considered fit for service when the failure modes that have beenidentified through the systematic process outlined in this OSS have been properly addressed, and the supportingevidence substantiates that the technology fulfils all stated functional requirements and meets the statedreliability target.

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


304 Hazard: A deviation (departure from the design and operating intention) that could cause damage, injuryor other form of loss (Chemical Industries Association HAZOP Guide).

305 HAZID (HAZard IDentification): A structured review technique with the purpose of identifying allsignificant hazards associated with the particular activity or operation under consideration.

306 New technology: Technology that is not proven. This implies that the application of proven technologyin a new environment or an unproven technology in a known environment, are both new technology. Thedegree of new technology will be classified in categories to be used as input to risk assessment.

307 Probability of success: The probability of completing a qualification activity or a set of qualificationactivities within available time and with a successful result.

308 Proven technology: In the field, proven technology has a documented track record for a definedenvironment. Such documentation shall provide confidence in the technology from practical operations, withrespect to the ability of the technology to meet the specified requirements.



309 Risk: The qualitative or quantitative likelihood of an accident or unplanned event occurring, consideredin conjunction with the potential consequences of such a failure. In quantitative terms, risk is the quantifiedprobability of a defined failure mode times its quantified consequence.310 Risk reduction measures: Those measures taken to reduce the risks to the operation of the technologyand to the health and safety of personnel associated with it or in its vicinity by:

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

311 Statement of endorsement: A document issued by DNV affirming that, at the time of assessment, it hasbeen found that the new technology can be proven fit for service through the remaining planned qualificationactivities.312 Statement of feasibility: A document issued by DNV affirming that, at the time of assessment, the newtechnology is considered conceptually feasible and suited for further development and qualification accordingto the principles outlined in DNV-RP-A203.313 Certificate of fitness for service: A document issued by DNV affirming that, at the time of assessment,the new technology is considered fit for service.314 Technology qualification: A confirmation by examination and provision of evidence that the newtechnology meets the specified requirements for the intended use. Hence, qualification is a documented set ofactivities to prove that the technology is fit for service.315 Verification: An examination to confirm that an activity, a product or a service is in accordance withspecified requirements.

SECTION 2PRINCIPLES OF TECHNOLOGY QUALIFICATION

A. General

A 100 Objective

101 The objective of this section is to give a brief overview of the principles of DNV’s TechnologyQualification work process for new technology as a background for understanding DNV’s qualificationmanagement services as described in Sec.3.

102 A thorough guidance regarding the application of the work process is given in DNV-RP-A203.

B. The Qualification Process

B 100 General

101 Qualification of new technology is a systematic process consisting 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 basis

201 The purpose of the qualification basis is, in the absence of relevant codes and procedures, to define theexpectations of the technology. Through further qualification processes these expectations shall be proven tobe fulfilled.

202 The qualification basis should include the following key elements:

— description of the technology to be qualified including system boundaries and operational limitations— functional requirements— reliability targets related to safety as well as functional performance.

B 300 Technology assessment

301 The purpose of the technology assessment is to divide the technology into manageable elements in orderto assess those elements that involve aspects of new technology and identify the key challenges anduncertainties.

302 The technology assessment shall include the following issues:

— division of the technology into manageable elements (see 303)— assessment of the technology elements with respect to newness (see 304)— identification of the main challenges and uncertainties related to the new technology aspects (see 305).

303 The technology division shall be achieved by dividing the technology into one or more of the followingtypes of elements, as relevant:

— sub-systems and components with functions— process sequences or operations— project execution phases based on procedures for manufacturing, installation and operation.

304 The degree of novelty of the technology shall be determined by classifying the technology elements withrespect to application area and technology maturity. Elements classified as new technology shall be subject tothe further assessment.

305 The main challenges and uncertainties related to the new technology aspects shall be identified. Forcomplex systems it is recommended that the main challenges and uncertainties are identified by carrying out ahigh level HAZID (HAZard IDentification).



Guidance note:

A high level HAZID is a means of obtaining a better understanding of a system at an early stage, and to identify whichparts of the system that need to be further developed and/or documented in more detail, prior to the failure modeidentification and risk ranking.


B 400 Failure mode identification and risk ranking

401 The objective of this step is to identify all relevant failure modes of concern for the elements defined asnew technology in the technology assessment and, for each, judge the associated risks.

402 Prior to the identification of failure modes various classes of probability and classes reflecting theconsequence severity shall be qualitatively defined. Based on these definitions a risk matrix shall be definedshowing fully acceptable combinations (“low risk”) and unacceptable combinations (“high risk”) as well asintermediate combinations (“medium risk”) of probability and consequence classes.

403 All relevant failure modes shall be assigned a probability class and consequence class based ondocumented reliability or expert judgements. In the latter case uncertainties shall be reflected by selectingconservative classes.

404 For relatively complex systems the failure mode identification and risk ranking process is recommendedto be carried out as workshops, involving a panel of experts covering the necessary fields of competences andexperiences.

B 500 Concept improvement

501 The objective of the concept improvement step is to implement improvements that have been foundnecessary or beneficial during the failure mode identification and risk ranking.

502 Improvements would normally imply that the previous steps in the qualification process need to beupdated.

B 600 Selection of qualification methods

601 The objective of this step is to select qualification methods that adequately address the identified failuremodes of concern with respect to reduction of uncertainties and documentation of sufficient margins of failure.

602 The qualification methods will, in most cases, include technical analyses, testing or combinations of thetwo where the purpose of the testing is to reduce uncertainty in the analysis model or calibrate it. They mayalso involve collection of available reliability data and making procedural precautions to avoid the associatedproblem.

603 The selected qualification methods will be input to a technology qualification plan (TQP) where thevarious issues will be outlined as qualification activities needed to be executed.

B 700 Evaluation of the probability of success

701 The objective of this step is to give a good indication of the probability of completing the remainingqualification program successfully. This is intended to give a basis for the decision to proceed with the analysisand testing phase.

702 The evaluation will normally be a judgement of the likelihood of each individual activity in thequalification plan to give a successful outcome taking the technical challenges and available time intoconsideration. When given as a quantitative estimate, this is referred to as the probability of success (PoS). Anoverall PoS for all activities may also be made, and economical considerations may be included when agreedwith the client.

B 800 Data collection (analyses and testing)

801 The objective of the data collection phase is to carry out all the qualification activities prescribed in theTQP.

802 If a reliability target is stated in the qualification basis, then an adequate reliability analysis shall becarried out taking the new information from the data collection into account.

B 900 Functionality assessment

901 The objective of this phase is to confirm that the functional requirements and target reliability as statedin the qualification basis are met.

902 This shall be done by confirming that the qualification activities have been carried out, and that theacceptance criteria for the analyses and testing have been met.



SECTION 3SERVICE OVERVIEW

A. General

A 100 Objectives101 The objectives of this section are to:

— give an overview of the various types of tasks that are part of DNV’s qualification management and fitnessfor service verification services

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

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

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

202 Qualification management is a service where DNV assists the client in the facilitation of the qualificationprocess described in Sec.2. This implies that DNV carries out a substantial part of making plans, preparing andchairing work shops, proposing methods for uncertainty reductions and documentation of the process.203 Fitness for service verification involves being an observer to the qualification process described in Sec.2as well as verifying technical documentation and witness tests to an extent necessary to issue the DNVqualification statements.204 Fitness for service verification shall not be carried out on technology where DNV has ownership or hascommercial interests in any way other than being compensated for the value of the provided service.205 Qualification execution comprises the types of work needed to create the various types of information,such as:

— providing technical expertise in failure mode identification 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, provide services where any of the roles defined in A200 arecombined to maximise the value of the services to the Client without threatening DNV’s integrity.302 When qualification execution tasks are provided in combination with fitness for service verificationdifferent personnel will be used in the different roles in order to maintain the integrity of DNV as anindependent verifier. Further, the verifier shall be involved during the whole qualification execution process inorder to proactively comment on issues before they become irrevocable.

A 400 Combined roles in the qualification process401 Technology Qualification Services may be executed as an integral part of product certification, see Sec.1B104 with guidance note.

B. Qualification Management

B 100 Definition of qualification basis101 The qualification basis may be development predominantly by DNV or written by the client andreviewed by DNV.102 Input for the qualification basis may include design basis or functional specification, which includes adescription of 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

as abandonment



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

B 200 Technology assessment

201 The technology assessment may be carried out by DNV with input from and comments by the client orbe carried out by the client and commented by DNV.

202 The input for the technology assessment shall be the qualification basis with supporting documents aslisted 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 tasks listed in Sec.2 B300.

B 300 Failure mode identification and risk ranking

301 The failure mode identification and risk ranking process should be managed by DNV in cooperation withthe 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 expertise— report the failure mode assessment.

302 The failure mode assessment should normally be conducted as workshops to be planned, chaired andreported by DNV. However, for simple systems and components the failure mode assessment may be carriedout more rationally by in-office work where input and comments from the relevant expertise is achieved bycirculation of the records.

B 400 Concept improvement

401 When specified by the Client, DNV will call attention to identified areas for possible improvements orrisk reduction measures.

B 500 Selection of qualification methods

501 The selection of qualification methods may involve descriptions of the methods of qualification atdifferent levels of detail depending on the purpose of the assessment.

502 In this context a brief description of the qualification methods implies a minimum level of detailsnecessary to serve as a basis for the PoS evaluation and for later development of detailed descriptions of thequalification methods. In particular, this implies that the means and purpose of the data collection must bedescribed unambiguously.

503 In this context a detailed description of the qualification methods implies that the data collection isdescribed at a procedure level necessary to carry out the activities and obtain satisfactory results.

B 600 Success evaluation

601 The success evaluation may be carried out at various levels of sophistication depending on the client'sneeds for information into their own decision process and accessibility to input parameters.

602 The evaluation will normally be assessed on a qualitative basis with respect to technical challenges andavailable time to qualification. When given as a quantitative estimate, this is referred to as the PoS.

603 A more sophisticated and informative assessment of the total PoS for the whole qualification may becarried out in order to give the PoS as function of time. The assessment requires that a qualification executionplan, that includes all qualification activities, is prepared and that both the probability of a successful outcomefor each activity, and the uncertainty in the durations are estimated.

604 An economic assessment of the qualification activities may be carried out following the same principles,where the time parameter is replaced by costs. This requires that cost estimates with uncertainties are estimatedfor each qualification activity.



B 700 Data collection (analyses and testing)701 The data collection shall be carried out by the client and/or the client’s subcontractor unlesssubcontracted to DNV as qualification execution (see D).702 For the purpose of issuing a DNV certificate of fitness for service it is required that DNV is involved inthe data collection phase to an extent necessary to testify that the analyses and tests have been executedaccording to the technology qualification plan and that results are derived and reported correctly. Thisinvolvement shall be agreed upon in each individual case.

B 800 Functionality assessment801 For the purpose of issuing a DNV certificate of fitness for service, DNV shall review and evaluate thefunctionality assessment against the qualification basis, to confirm that compliance with the functionalrequirements and reliability targets has been adequately documented.

C. Fitness for Service Verification

C 100 General101 The objective of the fitness for service verification is to testify that the technology qualification processhas been executed in accordance with this OSS and the principles outlined in DNV-RP-A203. Additionally,that the functional requirements and reliability targets as stated in the qualification basis have been adequatelyaddressed, as relevant, at the given stage of the qualification process.102 The fitness for service verification may be carried out as a separate service or integrated withqualification management.103 When carried out as a separate service DNV may carry out the fitness for service verification in parallelwith the client’s qualification process. As a minimum, DNV shall take part in the failure mode and risk rankingprocess or compensate for DNV’s absence by alternative arrangements. 104 DNV may on this basis issue statements as outlined in E400.

D. Qualification Execution

D 100 General101 Qualification execution comprises the type of work needed to create the various types of informationrequired into the qualification process. The services may include

— participation in failure mode identification and risk ranking 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 Deliverables

E 100 General101 The main DNV deliverables are shown schematically in Figure 1. The deliverables can be seen in relationto typical milestones in offshore field development projects, where information from the qualification of newtechnology process is needed as an basis for decisions (“decision gates”), as schematically illustrated in Figure2. It is shown that the milestones for the qualification process may depend on whether the new technology isregarded as an alternative to an available qualified 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 management service leads to the following DNV reports,unless agreed otherwise:



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 following statements and certificates (see Figure 2) basedon the criteria given 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 respective reports listed in 301 or similar report(s). 403 Following a technology assessment, a statement of feasibility can be issued provided that the newtechnology is considered conceptually feasible (see definition in Sec.1 C311), and thereby suited for furtherdevelopment and qualification according to the principles outlined in DNV-RP-A203.

Guidance note:There is an established practice by classification societies, in particular within the maritime industry, to issue acertificate titled “Approval in Principle”. An “Approval in Principle” may be issued as equivalent to a “Statement ofFeasibility” when properly referring to this OSS.


404 At the TQP milestone, a statement of endorsement is issued provided that it is found that the newtechnology can be proven fit for service (see definition in Sec.1 C303) through the remaining plannedqualification activities.405 At the TQ milestone, a certificate of fitness for service is issued provided that the new technology isconsidered fit for service (see definition in Sec.1 C303).

F. Determination of Scope of Work

F 100 Introduction101 The extent of involvement by DNV in the various activities within qualification management and fitnessfor service verification may vary depending on the complexity of the technology, the maturity of the conceptand the client’s needs for information into their own processes. Various activities have been described in orderto form a basis for selection of services to be included in DNV’s scope-of-work for a particular project. Theservices are tabulated in App. B as a form for selection of services.102 In order for DNV to provide services in line with the client’s needs good lines of communication needto be established at start-up of the project. A check list intended to be used at project start-up is given in App.C, to aid in this process.
