Background, Scope, and Purpose

1.1

Background

In August 2013, the U.S. Department of the Interior's Bureau of Safety and Environmental Enforcement (BSEE) and
the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) signed an Interagency Agreement
(IAA) to develop and implement SafeOCS, as a voluntary program for confidential reporting of 'near misses'
occurring in oil and gas production on the Outer Continental Shelf (OCS). BSEE and the BTS entered into a
Memorandum of Understanding (MOU) in August 2016 to allow BTS to collect equipment failure data required
under BSEE rules for reporting blowout preventer (BOP) system or component failures (30 C.F.R.§ 250.730(c)) and
safety and pollution prevention equipment (SPPE) failures (30 C.F.R.§ 250.803). On October 26, 2016, the BSEE
director announced the expansion of the SafeOCS program beyond near miss reporting to include the confidential
collection of equipment failure data pursuant to regulations 30 C.F.R.§ 250.730(c) and 30 C.F.R.§ 250.803.
Data collected by BTS under the IAA is protected under the Confidential Information Protection and Statistical
Efficiency Act of 2002 (CIPSEA) (44 U.S.C. §3501). This means: a) data collected by BTS under SafeOCS are protected
from inquiries of other government agencies, including BSEE, Freedom of Information Act (FOIA) requests, and
subpoena; b) data on near miss incidents collected under SafeOCS may not be used for regulatory purposes; and c)
only aggregate statistics and analytical results generated from the data will be made available to interested parties
or released to the public.

1.2

Purpose

This document was developed to assist the offshore drilling operators and their representatives with the
completion and submission of equipment component failure notifications pursuant to regulation 30 C.F.R.§
250.730(c).
Federal regulation 30 C.F.R.§ 250.730(c) was established to ensure accurate reporting of BOP system and
component failures, from initial notification to investigation and failure analysis, communication of failure
information and lessons learned, and design and procedural changes.

8.4

Root Causes: Definitions and Examples

The following are options available from the Root Cause dropdown box.

Assessment Pending:

This should be selected if, for instance, the BOP stack is still subsea. The failure
will be investigated when the BOP stack becomes accessible and the root cause
can be evaluated.

Design Issue:

Inadequate equipment design or configuration.
This is typically identified after a root cause failure analysis (RCFA) has been
completed, or if the design issue has been previously identified by an RCFA or
manufacturer’s notification.

Documentation Error:

Failure related to procedures, specifications, drawings, reporting, etc.
For example, a control valve was delivered with documentation stating that the
rated working pressure (RWP) was 5,000 psi. The valve leaked and the subsequent
investigation showed that the valve was really only rated for 3,000 psi. This was a
documentation error because of the stated RWP.

Maintenance Error:

Mistake, misuse, or oversight during maintenance.
For example, a choke line flange leaked after the maintenance had been completed.
Investigation showed that the flange studs had been torqued to 380 Nm instead of
the 380-ft-lb stated in the procedure. This was a Maintenance Error.

29

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

Procedural Error:

Mistake, misuse, or oversight during operation.
For example, the BOP ram leaked, because test pressure was applied after closing
pressure was vented, but without the ram having first been mechanically locked.
This was an Operational Error.

QA/QC Manufacturing:

Failure related to manufacturing.
For example, a new annular piston was purchased from the OEM, but we were
unable to install it. Investigation showed that it had been machined incorrectly.

Wear and Tear:

An expected condition of a component that has reached a point where it is unable
to perform intended function as the result of usage.
If wear and tear is repeatedly selected for equipment that fails in operation, then
that could indicate that a review of the maintenance procedure is required.

RCFA Required:

Currently unknown root cause.
For example, a RCFA is always required if there was; a loss of a well barrier, if there
was an unplanned stack/LMRP recovery, or if there was a systemic/reoccurring
event. Either of the other investigation requirements can be promoted to an RCFA
if necessary.

Other / Comment:

The root cause is known, but is none of the above. Selection of ‘Other’ will open a free text
comment box.

8.5

Compliance

Completion and submission of the Failure Notification Form (Section 8.0) will ensure compliance with the written
failure notice requirements of 30 C.F.R.§ 250.730(c).

NOTE: Submission of the Failure Notification Form to SafeOCS does not fulfill the requirement of 30 C.F.R.§
250.730(c) to report failures to the OEM.

9.0

Investigation and Failure Analysis

In the event of a BOP system or component failure it is important to conduct an effective investigation and failure
analysis in order to identify the causes (i.e., physical, human, and systemic) and root cause(s) of a failure. This will
establish a knowledge base that the industry can use to instill safety and improve equipment/component reliability.

There are several major approaches to investigation and failure analysis that are used within the industry, e.g.,
events and causal factor analysis, change analysis, barrier analysis, management oversight and risk tree analysis,
etc. Any one of these approaches should be selected in order to verify the root cause (see section 8.4) and identify
the causes (physical, human, or systemic) of the failure.

The scope of any investigation and analysis related to the equipment/component failure must be based on factual
information (e.g. hose failure, valve leaking in closed position).

9.1 Failure Causes
As part of the investigation and failure analysis process, three types of causes are identified. These are: physical,
human factor, and systemic causes.

9.1.1 Physical Causes
The consequence, manifestation, or results determined through evidence that have influenced or triggered a
component failure. Examples include corrosion, fatigue, excessive stress, erosion, rupture, etc.

9.1.2 Human Factor Causes
These are related to human activities that have contributed to the failure of a system or component. Identifying
and understanding the contribution of human factors during component failure investigations will improve
corrective action identification and component performance. Examples include maintenance error, failure to follow
procedures, etc.

31

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

9.1.3 Systemic Causes
These are related to any system or process activity rather than other specific isolating factors, including failures in
the procedures used to execute the work.
NOTE: If the failure is part of a wider event, then the appropriate investigative procedure may need to be
followed IN ADDITION to the creation of the WCR report on component failure.

9.2 Analysis Overview
This section presents the three levels of investigation and failure analysis. Please refer to the flow chart in appendix
3 for additional information and clarification:
•

Cause Immediately Known

•

Subject Matter Expert (SME) Review

•

Root Cause Failure Analysis

NOTE: If an investigation at one level fails to sufficiently determine the root cause(s) of the failure, then analysis
can proceed to the next level.
If the root cause is immediately known, then this information is submitted to SafeOCS (See Appendix 3).
If the equipment failure 1) resulted in a loss of a well barrier, 2) required the LMRP or BOP stack to be retrieved, or
3) has become a systemic/recurring event, then a Root Cause Failure Analysis (RCFA) should be conducted,
documented, and submitted to SafeOCS.
If the equipment failure does not involve any one of the above-mentioned events (1, 2, or 3), then a SME Review
should be conducted, documented, and submitted to SafeOCS.
NOTE: There will be occasions when a component failure previously categorized as either ‘Cause Immediately
Known’ or ‘SME Review’, is reclassified as ‘Systemic/Reoccurring’ (#3) due to multiple occurrences
requiring a ‘RCFA’. As such, the previously submitted report does not need to be re-classified and may be
referenced (and modified if necessary) in the SME Review or RCFA.

32

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

The Failure Notification Form can be updated (as needed) during the investigation and analysis process. The
document can be uploaded, along with additional information, using the BTS unique reference number or identifier
that was assigned to the original Failure Notification Form.

9.3

Level One: Cause Immediately Known

9.3.1 Example of Cause Immediately Known
An O-ring damaged during installation normally can be easily categorized as Cause Immediately Known. It is
important to report such issues, because if this were to escalate to a systemic/reoccurring event, then it may
warrant a change to the design or installation/maintenance procedures.

9.3.2 Resources
The Senior Subsea Engineer should discuss what happened with another technical member of crew to determine:
•

What happened?

•

How it happened?

•

Why it happened?

A description of the event and other appropriate information should be provided on or with the Failure Notification
Form.

9.3.3 Closure
The investigation is considered closed when the cause is immediately known and the information is provided (see
9.3.1 and 9.3.2). The system will process the resubmittal, thus fulfilling the regulatory requirement. Cases that do
not show a cause immediately known are discussed next under Level Two (9.4) and Level Three (9.5).
If the Failure Notification Form has previously been submitted as “final”, it may still be modified or updated as
appropriate. Supporting documentation can be added by using the unique BTS reference number or an equivalent
unique identifier that was assigned to the original Failure Notification Form by the SafeOCS system.

33

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

9.4

Level Two: Subject Matter Expert Review (SME)

A SME Review should be conducted when the cause of the failure is questionable and the component failure has
not triggered an RCFA (not an unplanned BOP pull, loss of well barrier, or a systemic/reoccurring event).
An SME Review is conducted when:
•

a failed component requires disassembly to ascertain the cause of the failure,

•

the event frequency is not systemic – (see Appendix 1), or

•

the consequence (no loss of barrier or BOP retrieval) of the component failure are considered low.

However, a Root Cause Failure Analysis (RCFA) might be triggered based on a SME review findings.

9.4.1 Example of a SME Review
If a ram failed to hold pressure during pre-deployment testing and upon opening the doors/bonnets it was apparent
that the packers were well worn, then a SME Review could check the records to see if the number of functions met
expectations. Then, after the rams have been successfully tested with new packers to confirm that there was no
other issue, and assuming the number of functions met expectations, the failure can be attributed to ‘Wear and
Tear’. However, if the rams fail to test and/or the function cycles are less than expected, then the causal agent is
something other than ‘Wear and Tear’.

9.4.2 Resources
Two or more SME’s.
The SME Review should show a logical conclusion based on sound evaluation of the physical causes of what, how,
and why a failure occurred. Furthermore, the report must be produced either by cross-referencing the assigned
unique reference numbers or located using the following information contained within the report:
•

Details of the component that failed (Part Number, Serial Number, Description)

•

Date of the failure

•

Details of the failure

•

Date that the SME Review commenced and was completed

•

Investigation team member description

34

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

•

Failure cause(s)

•

Findings

•

Corrective Actions taken

•

Recommendations

9.4.3 Closure
The incident can be considered closed when the component failure form in the database is updated (closing the
initial report) and the final report is published. A Failure Notification Form that has either been modified or updated,
must include the necessary documentation supporting the identified cause(s) and attached using the unique BTS
reference number or equivalent unique identifier.

9.5

Level Three: Root Cause Failure Analysis (RCFA) Required

The RCFA is a more detailed investigation requiring more time and resources to complete. There are three specific
triggers for when a RCFA should be carried out (see Figure 9.1).
The result of the RCFA can be used to correct specific problems and prevent reoccurrence, for instance: OEM
product bulletins, equipment owner maintenance system changes, etc.

Was there loss of a
well barrier?

YES

NO

Was there an
unplanned stack/LMRP
recovery?

YES

The Operator ensures
that a RCFA is arranged.

NO

Is it a systemic/
recurring event?

YES

NO

9.5.1 Physical Evidence
In many instances, well control component failures are frequently field repairable, but there may be cases when a
replacement assembly may not be readily available. In such an event, ensure that a full and detailed documentation
of the physical evidence is provided. In extreme and pressing circumstances photographs, dimensions, sketches,
and written reports can also be substituted and submitted as further evidence.

9.5.2 Resources
Typically, this includes at least one SME plus an OEM representative or a suitably qualified third party.
The RCFA report should include the causes (physical, human, and systemic) and the reasons (what, why, and how)
for the failure occurrence.
To be considered in compliance with the regulatory requirements (30 C.F.R.§ 250.730(c)), the RCFA documentation
should include the following:
•

A copy of the initial report

•

An accurate description of the failure

•

Detailed information on the operating conditions that existed at the time of the malfunction or failure
and any applicable operating conditions that existed prior to or immediately after the failure

•

Description of the immediate corrective actions that were taken as identified in the failure
notification

•

Any relevant operating history of the equipment prior to the failure (e.g. field repair, modifications
made, etc.)

•

Description of any inspection, testing, laboratory analysis, or other activities conducted to determine
the root cause and causal factors

•

Description of the causal factors determined to be associated with the failure

•

Additional equipment problems beyond the initial failure notification identified during the failure
analysis

•

Other conclusions or findings resulting from the investigation and failure analysis

•

Corrective actions recommended and taken in addition to the immediate corrective actions noted in
the initial report, if known at the time of the investigation and analysis report

•

Photographs, pressure tests, inspection records, laboratory analyses results, verification documents,
etc. to support the investigation and failure analysis conducted.

36

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

9.5.3 Closure
The incident can be considered closed when the component failure report in the database is updated (closing the
initial report) and the final report is published. A Failure Notification Form that has either been modified or updated
must include the necessary documentation supporting the identified cause(s) and attached using the unique
reference number or equivalent unique identifier.

9.6

Compliance

Pursuant to 30 C.F.R.§ 250.730(c), a failure report shall be generated for each failure of any well control
system/component whether there is NPT or not. To facilitate the accomplishment of this responsibility, this
guidance document established protocols governing the reporting and subsequent investigations of a well control
incident.

10.0 Capture and Share Lessons Learned
When developing protocols for identifying, investigating, reporting, and maintaining records of incidents and
failures, it is important that each of these events serves multiple purposes. For instance, proper investigation and
reporting assists OEM’s and owners identifying problematic areas and weaknesses that can be improved ensuring
equipment safety and reliability.
Pursuant to 30 C.F.R.§ 250.730(c), it is important that lessons learnt from component failures are shared with the
appropriate industry stakeholders.

11.0 Reporting Design and Procedural Changes
Pursuant to 30 C.F.R.§ 250.730(c), changes in design and operating procedures (resulting from a failure) that were
not submitted as part of the Failure Notification or Investigation and Failure Analysis reporting process must be
submitted to SafeOCS within 30 days. This information should include the unique reference number assigned by
the SafeOCS system or an equivalent unique identifier established when the Failure Notification Form was originally
submitted.

APPENDIX 1

DEFINITIONS

GENERAL DEFINITIONS
BOP Stack Pull (Subsea)

When either the BOP is removed from the wellhead or the LMRP is
removed from the lower stack to repair a failed component. The BOP stack
cannot be classified as a stack pull until after it has been in-operation.

BOP Stack Pull (Surface)

When a BOP component fails during operations and requires well
conditioning and a mechanical barrier placement to make necessary
repairs.

Cause

Something that initiates, shapes, or influences an outcome.

Cause Immediately Known

When there is a high degree of certainty in the failure cause, the failure
information described in Section 3 is completed describing the failure and
defining the root cause based on inspection and maintenance personnel
experience and knowledge.

Corrective Action

An action, which is taken to correct a failure and/or the failure’s cause.

Effect

An event or condition that is caused by another event or condition.

Evidence

Information, data and/or items gathered which directly relate to, or have
been, affected by the failure.

Failure

A condition that prevents the component from operating as designed,
e.g. A leaking O-ring is a failure even if the piston that it should seal can
fully stroke.

In-Operation (Subsea)

A BOP stack is in-operation after it has completed a successful pressure
test of the wellhead connection to the well-bore per approved well plan.

In-Operation (Surface)

A surface BOP stack is in-operation after it has completed a successful
pressure test of the wellhead connection to the well-bore per approved
well plan.

Non-productive time (NPT)

The number of hours that is inclusive of BOP recovery and reinstallation
etc., plus all time in-between failure detection and getting back to the
point (in the well operation) at which the failure occurred.

39

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

Not in-operation (Subsea)

The BOP stack changes from in-operation to not in-operation when either
the BOP is removed from the wellhead or the LMRP is removed from the
lower stack. When running or pulling (retrieving) the stack, the BOP stack
is not in-operation.

Not in-operation (Surface)

A surface BOP changes from in-operation to not in-operation when the
well is conditioned and a mechanical barrier is set in the wellbore.

Preventative Maintenance

Maintenance carried out at predetermined intervals or according to
prescribed criteria and intended to reduce the probability of failure or the
degradation of the functioning of an item.

Rated Working Pressure (RWP)

The maximum internal pressure that equipment is designed to contain or
control in the form of standardized pressure ratings.

Reoccurring/Systemic Event

A failure that occurs periodically or repeatedly. A reoccurring event, also
known as a systemic event, may be identified at:

Root Cause

•

an individual component or equipment system level,

•

a company’s level, or

•

an industry-wide level.

The cause (condition or action) that begins a cause/effect chain and ends
in the equipment component failure. If eliminated, it would prevent the
reoccurrence of the event (under investigation) and similar occurrences.

Root Cause Failure Analysis (RCFA)

A comprehensive systematic investigation process undertaken to identify
Physical, Human Factors and Systemic root causes of a component
failure.

SafeOCS Subject Matter Expert

A person or persons with an in-depth knowledge of a subject of interest,
hired or appointed by the Government to evaluate failure submissions in
accordance with 30 C.F.R.§ 250.730(c).

SafeOCS SME Review

An evaluation of failure submissions by a SafeOCS SME to determine the
gravity of a failure event’s potential consequence with respect to
equipment context, causal factors, and other considerations.

Skipsteknisk Forskningsinstitutt (SFI)

Ship Research Institute of Norway

40

Subject Matter Expert

Your designated person or persons with an in-depth knowledge of a
subject of interest. Such knowledge will have been gained through direct
and practical dealings with subject matter of interest.

SME Review

An internal assessment of the possible and probable local root cause of
the component failure reviewed by a SME with the intent of
recommending intermediate actions or changes to reduce the probability
of reoccurrence.

ROOT CAUSE DEFINITIONS (as used in the failure notification Input Form (Appendix 2) and Section 1 of the
Investigation and Failure Analysis Summary Form.
Assessment Pending:

This should be selected if, for instance, the BOP stack is still subsea. The failure will
be investigated when the BOP stack becomes accessible and the root cause can be
evaluated.

Design Issue:

Inadequate equipment design or configuration.
This is typically identified after an RCFA has been completed or if the design issue
has been previously identified by RCFA or manufacturer’s notification.

Documentation Error:

Mistake or oversight in the documentation used by equipment operatives.
The installation, operations and maintenance documents were followed but there
were inherent errors in the documentation supplied. The documentation can be in
the form of drawings, manuals, procedures, work instructions and work orders and
can be supplied by the OEM, System Integrator or the Equipment Owner.

Maintenance Error:

Mistake, misuse or oversight during maintenance.
A choke line flange leaked after the maintenance had been completed.
Investigation showed that the flange studs had been torqued to 380 Nm instead of
the 380-ft-lb stated in the procedure. This was a Maintenance Error.

Procedural Error:

Mistake, misuse or oversight during operation.
The BOP ram leaked because test pressure was applied after closing pressure was
vented, but without the ram having first been mechanically locked. This was an
Operational Error.

QA/QC Manufacturing:

Failure related to manufacturing.
A new annular piston was purchased from the OEM but we were unable to install
it. Investigation showed that it had been machined incorrectly.

41

SafeOCS Well Control Failure Reporting Guidance Document. Rev. 2.00

Wear and Tear:

An expected condition of a component that has reached a point where it is unable
to perform intended function as the result of usage.

RCFA Required:

Currently unknown root cause.
An RCFA is always required if there was; a loss of a well barrier, if there was an
unplanned stack/LMRP recovery, or if there was a systemic/reoccurring event.
Either of the other investigation requirements can be promoted to an RCFA if
necessary.
