COMPETENCE GUIDANCEPreventing Hydrocarbonreleases through
safetycritical competence
2. Mechanical joints have the potential to cause serious injury
andhydrocarbon releases. This has been seen in the last few years
wherea number of serious incidents and accidents have occurred
duringconstruction, maintenance, disassembly and steady-state
operations.Competence related failures are one of the main causes
of loss-of-containment incidents, and may lead to major
accidents.As a result of this, there is a strong desire within the
oil and gas industryto improve the safety performance of such
operations. To achieve thisaim, a work group was established to
produce this Mechanical JointIntegrity Competence guidance.This
guidance reflects current industry practice guidance as well asa
definition of minimum standards of competency for carrying outsuch
work. It has been developed by a joint working group
includingmembers from industry and standard setting bodies. In
compiling thisdocument, it was recognised that organisations
already have processesand procedures. With this in mind, they are
designed to provideguidance in two ways: To enable you to assess
your current working methods against theprinciples put forward here
and so help you identify improvementsto those methods in line with
current best practice. To allow companies to adopt improved methods
for demonstratingspecialist critical bolting and small bore tubing
competence, basedon current good practice.We recommend the review
of company procedures against theprinciples and practical guidance
contained in this publication. Anaction plan should then be
prepared for the implementation of anynecessary
improvements.Effective and lasting improvement can be achieved
where all concerned,from senior management to those carrying out
work on the plant, sharea genuine commitment to achieving and
maintaining mechanical jointoperations procedures to a high
standard.AN OVERVIEW
3. Scope and Target AudienceThe guidance sets out a structured
approach to the principles ofmanaging competence for those involved
in mechanical joint operations.It describes how to train, develop
and assure competence, reducingthe risk of personal injury and
hydrocarbon and non-hydrocarbonrelease when working with mechanical
joint related activities such asconstruction, maintenance and
disassembly operations.The guidance is intended to reflect industry
good practice for themanagement of competence in relation to
mechanical joint operations.It applies to the onshore and offshore
oil and gas industry to the extentthat it is reasonably practicable
to do so. It also has general applicationto all industries where
mechanical joint operations are undertaken.These guidelines are
therefore aimed at all personnel involved inmechanical joint
operations, particularly those who are expected toundertake related
duties in the workplace. Correspondingly those whoare expected to
plan these operations and the supervisors of thosepersonnel
performing them should be familiar with these
principles.Additionally those involved with the management of
training andcompetence, including the delivery of related material
should be aware of the importance of utilising good practice in the
demonstration ofcompetence of new and existing workers; a revised
and restructured development routesRisk ReductionThe main focus is
on risks to the safety of people and avoiding lossof containment,
particularly where activities present potential majoraccident
hazards. It will also improve environmental protectionand reduce
business interruption. For all assembly and disassemblyoperations
the risks should be formally assessed.Overview of HazardFire and

4. Basic PrinciplesControl of the training and competence
assurance of personnel working on mechanical joints is a critical
factor inachieving asset integrity. Therefore an important element
of the competence assurance and management system is toensure that
any person working on a given joint has been trained and assessed
as competent to perform the task.All personnel involved in
mechanical joint operations should have sufficient knowledge of the
specific tasks to beundertaken and the risks which the work will
entail, along with sufficient experience and ability to carry out
their dutiesin relation to mechanical joint integrity operations,
whilst recognising their limitations and be able to take
appropriateaction in order to prevent harm to themselves and those
affected by the work.Moreover personnel should be assessed as
technically competent. Formal assessment should be underpinned by
nationaloccupational standards and provides demonstrable capability
for all personnel, including third-party vendors andcontractors,
who are expected to make, break or maintain mechanical
joints.Personnel Undertaking Mechanical Joint Integrity
OperationsThe diagram on page 3 shows the four key stages that an
individual has to pass through to reach full competency andmaintain
ongoing performance development.The chart on page 8 and 9
identifies the categories of personnel who undertake or are
involved with Mechanical Jointoperations and the suggested training
and competence assessment for these groups of personnel.There are a
number of training courses available, which are based upon and meet
industry occupational standardsdeveloped by the ECITB a training
standards organisation.Four Key Stages in Achieving CompetencyThe
first stage of all training comprises initial training and
assessment. This is normally carried out at a training
establishment.At the completion of Stage 1, the level of competency
is deemed sufficient for that person to undertake Mechanical
JointIntegrity operations under the direct supervision of a
competent person as part of their Stage 2 training.Stage 2 is
consolidation of skills, experience building and the practical
application of the learning obtained in Stage 1.Stage 3 is the
assessment of technical competency at an approved test centre with
Stage 4 as the ongoing performancedevelopment.These four stages of
achieving competency in Specialist Critical Bolting and Small Bore
Tubing are shown in Fig 1.In order to conduct mechanical joint
integrity operations to todays high standards, it is important that
employers havea system in operation which permits personnel to
progress through the stages to become competent to
undertakemechanical joint integrity operations and to maintain this
competence.In the case of non-core personnel employed on short-term
contracts, employers must have a system in operation tovalidate the
competency of these personnel and, if necessary, update and refresh
the skills and knowledge of suchpersonnel.Key Stages of
MechanicalJoint Integrity Competence02
6. ROUTE TO COMPETENCE04New Workers and Existing WorkersNew
Workers who have no experience in working with mechanical joints
must start at Stage 1 of the training andprogress through Stages 2,
3 & 4 over time.Existing workers may go straight to Stage 3 (as
shown in Fig. 2) if their company can endorse that the existing
workerhas previously attended a training course in bolting or small
bore tubing and has recent experience in that subject area.Some
existing workers may require refresher training on the knowledge
aspects and computer based training moduleswill be available that
are aligned with ECITBs technical training standardsPersonnel
involved in mechanical joint integrity activitieswill attend an
ECITB approved training provider toundertake a period of training
in either specialist criticalbolting or small bore tubing
assemblies. The training willnormally take place onshore and
consist of classroom andworkshop learning activities. The courses
are normallyfrom one day to two and half days depending upon
thesubject matter. Each person will be taught theoreticaland
practical skills regarding the relevant subject matterto a
technical training standard specified by the ECITB.The training
courses require each person to demonstratethe attainment of
knowledge and practical skills throughan individual knowledge test
and practical workshopexercises. Successful personnel will gain a
certificate oftraining and be issued with a Work Based Task
Assignmentto be used in Stage 2.Each person after attending an
approved training courseand attaining the training certificate
requires a periodof workplace experience to practise new skills
andknowledge. This period allows for the consolidationof skills and
knowledge against work based tasks. Thelearner is issued with a
Work Based Task Assignmentspecifying the range of tasks and complex
jobs requiredbefore the person can move on to Stage 3. A
workplaceconsolidation period of 3 to 12 months is recommendedto
give the person the opportunity to complete the WorkBased Task
Assignment. The individual must satisfactorilydemonstrate that they
have carried out each of thesteps indicated in the Work Based Task
Assignment on aminimum of three occasions. This may mean in
practicethat they complete more than three task assignmentrecords
as they may not carry out every step on eachoccasion.The task
assignment record may be verified by anyperson with overall
responsibility for the correct, safe andaccurate completion of the
task. This could be: A supervisor or team leader A line manager Any
other person with responsibility for the finalapproval and quality
assurance for the relevant task,for example a QC Inspector or
permit authorityWhen the person has achieved satisfactory
completionof the Work Based Task Assignment they can move ontoStage
3.Stage 3 requires each person to complete a formalassessment of
their job knowledge, skills and abilityin each Mechanical Joint
Integrity subject. The ECITBtechnical competence validation tests
are standards basedconsisting of a bank of online knowledge
questions anda practical task to validate the learners skills,
knowledgeand ability. Successful learners achieve the certificateof
achievement which is valid for a period of 3 years.Unsuccessful
personnel must wait a minimum period of4 weeks between the
unsuccessful test session and nexttest session to allow a period of
training to address anyskills or knowledge gaps.To confirm the
individuals current skills, knowledge andability the ECITB
technical competence validation test isundertaken every 3 years to
prove ongoing performancedevelopment. If required the individual
can undertake ashort computer based training module to refresh
their jobknowledge before attempting the technical test.Stage
