Table C.6 — Examples of hazard identification and risk assessment considerations during the
procurement, construction and installation phases of field development activities
Activity: Field
development
Hazard
identification and
risk assessment
step
Identify hazards
Hazards and risk
assessment
Screening criteria
Risk-reducing
measures
Functional
requirements
Description: This activity includes all tasks involved in the planning, design, procurement, construction, installation
and commissioning of offshore installations used for the exploitation of oil and gas resources.
Subactivity: Procurement, construction and installation.
Examples of aspects to be considered and
Comments
activities undertaken
Hazards due to the transportation and storage of
hazardous materials
Fabrication-site hazards
Inspection and testing hazards
Load-out, marine transport, lifting and installation
hazards
Hook-up hazards
Hazards arising from high manning levels and many
different trades and contractors
Experience of previous and similar work
Codes and standards
Checklists and safety data sheets
HAZID and JHA
HAZOPs for non-standard construction and
installation operations
Health risk assessment
Criteria from national workplace health and safety
regulations
Limits of exposure to hazardous materials or toxic
gases
Company risk criteria
Company and international codes and standards for
offshore marine operations
Insurance requirements for construction and marine
operations
Identify safer construction sequences
Provide adequate working environment and all
necessary lifting and positioning aids
Use large-scale prefabrication
Employ extensive onshore pre-commissioning
Schedule offshore marine operations when severe
environmental conditions are less likely to occur
Use less hazardous materials in construction
process
Criteria for inspection and testing
Requirements forlifting, moving and positioning
objects
Local environmental requirements for different
construction activities such as welding, blasting,
painting, insulation, electrical termination, etc.
Requirements for movement of modules and decks
in the construction yard and load-out onto barges
Requirements for temporary systems during
construction, testing and pre-commissioning
Hot-work limits and concurrent working limitations
Minimization of offshore work, particularly hazardous
operations such as hot work
During this phase many different entities are involved; the
concession holder should ensure that all hazards are
identified and clear limits of responsibility established.
Where many different entities are working together, clear
responsibilities for evaluations need to be established. The
overall responsibility is the concession owner’s, but this may
be delegated in specific instances (e.g. fabricator to be
responsible for all evaluation work of subcontractors).
Extensive use of Permit-to-Work system incorporating use of
checklists and JHA.
The screening criteria that are applicable during operations
are rarely modified during this phase. There is however a
need to establish screening criteria to cover procurement,
construction, installation and hook-up tasks. Various entities
are responsible for establishing screening criteria and
undertaking the subsequent evaluations, but the concession
holder should coordinate and review these activities.
