DNV-OSS-401 Technology Qualification Management
|
SECTION 3
Service OverviewSec.3
A. General
Sec.3
A 100 Objectives
Sec.3 A
101 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 fitness for service verification services |
| — | give guidance on the selection of relevant scope of
work for qualification of new technology. |
Sec.3
A 200 Introduction to DNV's
services
Sec.3 A
201 DNV's possible roles in the qualification process
may be divided into three categories:| — | qualification management |
| — | fitness for service verification |
| — | qualification execution. |
Sec.3 A
202 Qualification management is
a service where DNV assists the client in the facilitation of the
qualification process described in Sec.2.
This implies that DNV carries out a substantial part of making plans,
preparing and chairing work shops, proposing methods for uncertainty
reductions and documentation of the process.
Sec.3 A
203 Fitness for service verification involves
being an observer to the qualification process described in Sec.2
as well as verifying technical documentation and witness tests to
an extent necessary to issue the DNV qualification statements.
Sec.3 A
204 Fitness for service verification shall not be carried out
on technology where DNV has ownership or has commercial interests
in any way other than being compensated for the value of the provided
service.
Sec.3 A
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. |
Sec.3
A 300 Combined roles in the qualification
process
Sec.3 A
301 DNV may, as a fully independent company, provide services
where any of the roles defined in A200 are combined to maximise
the value of the services to the Client without threatening DNV's
integrity.
Sec.3 A
302 When qualification execution tasks are provided in combination
with fitness for service verification different personnel will be
used in the different roles in order to maintain the integrity of
DNV as an independent verifier. Further, the verifier shall be involved
during the whole qualification execution process in order to proactively
comment on issues before they become irrevocable.Sec.3
A 400 Combined roles in the qualification
process
Sec.3 A
401 Technology Qualification Services may
be executed as an integral part of product certification, see Sec.1 B104 with guidance note.Sec.3
B. Qualification Management
Sec.3
B 100 Definition of qualification basis
Sec.3 B
101 The qualification basis may be development predominantly by
DNV or written by the client and reviewed by DNV.
Sec.3 B
102 Input for the qualification basis may include design basis
or functional specification, which includes a description 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. |
Sec.3
B 200 Technology assessment
Sec.3 B
201 The technology assessment may be carried out by DNV with input
from and comments by the client or be carried out by the client
and commented by DNV.
Sec.3 B
202 The input for the technology assessment shall be the qualification
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). |
Sec.3 B
203 The technology assessment shall include the main tasks listed
in Sec.2 B300.Sec.3
B 300 Failure mode identification
and risk ranking
Sec.3 B
301 The failure mode identification and risk ranking process should
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 expertise |
| — | report the failure mode assessment. |
Sec.3 B
302 The failure mode assessment should normally be conducted as
workshops to be planned, chaired and reported by DNV. However, for
simple systems and components the failure mode assessment may be
carried out more rationally by in-office work where input and comments
from the relevant expertise is achieved by circulation of the records.Sec.3
B 400 Concept improvement
Sec.3 B
401 When specified by the Client, DNV will call attention to identified
areas for possible improvements or risk reduction measures.Sec.3
B 500 Selection of qualification methods
Sec.3 B
501 The selection of qualification methods may involve descriptions
of the methods of qualification at different levels of detail depending
on the purpose of the assessment.
Sec.3 B
502 In this context a brief description of the qualification methods
implies a minimum level of details necessary to serve as a basis
for the PoS evaluation and for later development of detailed descriptions
of the qualification methods. In particular, this implies that the
means and purpose of the data collection must be described unambiguously.
Sec.3 B
503 In this context a detailed description of the qualification methods
implies that the data collection is described at a procedure level
necessary to carry out the activities and obtain satisfactory results.Sec.3
B 600 Success evaluation
Sec.3 B
601 The success evaluation may be carried out at various levels
of sophistication depending on the client's needs for information
into their own decision process and accessibility to input parameters.
Sec.3 B
602 The evaluation will normally be assessed on a qualitative
basis with respect to technical challenges and available time to
qualification. When given as a quantitative estimate, this is referred
to as the PoS.
Sec.3 B
603 A more sophisticated and informative assessment of the total
PoS for the whole qualification may be carried out in order to give
the PoS as function of time. The assessment requires that a qualification
execution plan, that includes all qualification activities, is prepared
and that both the probability of a successful outcome for each activity,
and the uncertainty in the durations are estimated.
Sec.3 B
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 estimated for each qualification activity.Sec.3
B 700 Data collection (analyses and
testing)
Sec.3 B
701 The data collection shall be carried out by the client and/or
the client's subcontractor unless subcontracted to DNV
as qualification execution (see D).
Sec.3 B
702 For the purpose of issuing a DNV certificate of fitness for
service it is required that DNV is involved in the data collection
phase to an extent necessary to testify that the analyses and tests
have been executed according to the technology qualification plan
and that results are derived and reported correctly. This involvement
shall be agreed upon in each individual case.Sec.3
B 800 Functionality assessment
Sec.3 B
801 For the purpose of issuing a DNV certificate of fitness for
service, DNV shall review and evaluate the functionality assessment
against the qualification basis, to confirm that compliance with
the functional requirements and reliability targets has been adequately
documented.Sec.3
C. Fitness for Service Verification
Sec.3
C 100 General
Sec.3 C
101 The objective of the fitness for service verification is to testify
that the technology qualification process has 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 adequately addressed, as relevant,
at the given stage of the qualification process.
Sec.3 C
102 The fitness for service verification may be carried out as a
separate service or integrated with qualification management.
Sec.3 C
103 When carried out as a separate service DNV may carry out the
fitness for service verification in parallel with the client's
qualification process. As a minimum, DNV shall take part in the
failure mode and risk ranking process or compensate for DNV's
absence by alternative arrangements.
Sec.3 C
104 DNV may on this basis issue statements as outlined in E400.Sec.3
D. Qualification Execution
Sec.3
D 100 General
Sec.3 D
101 Qualification execution comprises the type of work needed
to create the various types of information required 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. |
Sec.3
E. Service Deliverables
Sec.3
E 100 General
Sec.3 E
101 The main DNV deliverables are shown schematically in Figure 1. The deliverables can
be seen in relation to typical milestones in offshore field development
projects, where information from the qualification of new technology
process is needed as an basis for decisions ("decision
gates"), as schematically illustrated in Figure 2. It is shown that the
milestones for the qualification process may depend on whether the
new technology is regarded as an alternative to an available qualified
technology or the feasibility of the development project is dependant
on the new technology to be qualified.Sec.3
E 200 Milestones in the qualification
process
Sec.3 E
201 The milestones in the qualification process are:| TA | - | Finalisation of the technology assessment. |
| TQP | - | Completion of the technology qualification plan. |
| TQ | - | Technology qualified. |
Sec.3
E 300 Qualification management - DNV
reports
Sec.3 E
301 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. |
Sec.3
E 400 Fitness for service verification - DNV
statements and certificates
Sec.3 E
401 Fitness for service verification may lead to the following statements
and certificates (see Figure 2)
based on 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.
Sec.3 E
402 The statements in 401 shall be based on the respective reports
listed in 301 or similar report(s).
Sec.3 E
403 Following a technology assessment, a statement of feasibility
can be issued provided that the new technology is considered conceptually
feasible (see definition in Sec.1 C311), and
thereby suited for further development 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 a certificate
titled "Approval in Principle". An "Approval
in Principle" may be issued as equivalent to a "Statement
of Feasibility" when properly referring to this OSS. ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
Sec.3 E
404 At the TQP milestone, a statement of endorsement is issued
provided that it is found that the new technology can be proven
fit for service (see definition in Sec.1
C303) through the remaining planned qualification activities.
Sec.3 E
405 At the TQ milestone, a certificate of fitness for service
is issued provided that the new technology is considered fit for service
(see definition in Sec.1 C303).Sec.3
F. Determination of Scope of Work
Sec.3
F 100 Introduction
Sec.3 F
101 The extent of involvement by DNV in the various activities
within qualification management and fitness for service verification
may vary depending on the complexity of the technology, the maturity
of the concept and the client's needs for information into
their own processes. Various activities have been described in order
to form a basis for selection of services to be included in DNV's
scope-of-work for a particular project. The services are tabulated
in App. B as a form for selection of services.
Sec.3 F
102 In order for DNV to provide services in line with the client's
needs good lines of communication need to 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.
