Structural behaviour under explosion hazards
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. This document provides guidelines and recommended practice for the satisfactory design of offshore structures against fire and blast loading. Care ep required in converting back to the actual structure to ensure the additional stresses are captured, particularly at support locations of both the beam and at equipment support points Non-linear finite element analysis The most complex and extensive structural modelling process adopted is the finite element method which can potentially capture all of the non-linear material and geometric behaviour together with the dynamics.
Examples of evidence Some generic advice on methods that may be used to assess response are: These have been shown to act as stress raisers and potential failure sources, even at low pressures. Proceedings of an International Conference Submersible Technology: Safety critical elements Structural elements and systems are used in provision of control and barriers for explosions and are likely to be designated safety critical elements.
As a consequence there is the potential for an improvement in QRA models. Some guidance from onshore petrochemical guidelines existed but this was not always appropriate for offshore applications.
However aapi QRA process is quite complex and can be demanding which tends to limit the QRA by concentrating on representative scenarios. This policy should have no impact for new installations as designs should incorporate the required regulatory and technical principles. The methodology adopted was to apo a risk assessment for a typical bid to arrive at the sound cost estimate for the fire protection systems.
The most prominent leak scenarios for the study were considered as a part of the simplified approach in lieu of considering exhaustive scenario combinations based on different leak sizes, weather parameters, leak directions, etc.
The nature of the threat varies significantly with inventory detail, level of confinement and congestion which is almost always present on North Sea layouts. This publication serves as a guide for those who are concerned with the design and construction of new platforms and for the relocation of existing platforms used for the drilling, development, and storage of hyd This Recommended Practice is intended to serve as a guide to crane owners and operators in developing operating and maintenance practices and procedures for use in the safe operation of pedestal-mounted revolving cranes on fixed or oating offshore platforms, jacku This document recommends minimum requirements and guidelines for the design and installation of electrical systems on fixed and floating petroleum facilities located offshore when hazardous locations are classified as Zone 0, Zone 1, r Zone 2.

Abstract Projects with accelerated engineering, procurement, and construction EPC schedules are becoming common in the oil and gas industry with Oil Majors keen on quick and guaranteed returns on investment. Even if confinement is reduced, high levels of congestion can actually create confinement and enhance the explosion experienced by the surrounding plant and structure.
International Journal of Impact EngineeringVol.
Post Piper, several bars of pressure were found to be a real possibility with realistic levels of congestion and confinement. Nature of threat The potential for an accidental release of a hydrocarbon mixture is ever present on hydrocarbon carrying installations and, if ignited, could lead to a serious incident involving loss of life, loss of the asset and environmental damage.
The magnitude of the explosion loads for which the installation is designed should reflect the residual risks to persons on the installation from explosion in line with the ALARP principle.
This also changes if modifications made to the structure increase inventories. Rock Mechanics Symposium and 5th U. Ongoing operational safety shall be demonstrated by appropriate design capacity in conjunction with an appropriate integrity management system to ensure degradation is kept within acceptable limits.
Previous research has shown that as the gas cloud increases a runaway length can be reached at which point the overpressure increases significantly. Advanced search Show search help. Proceedings of an international conference Subsea Controls and Data Acquisition ‘ This method is often described as simple because of the simplicity of the idealisation and the fact you can obtain a response time history using a spreadsheet hence conducting parametric studies which are useful for screening different pressure time histories.

In some cases this can lead to ignoring the low 2db high consequence events. The potential for an accidental release of a hydrocarbon mixture is ever present on hydrocarbon carrying installations and, if ignited, could lead to a serious incident involving loss of life, loss of the asset and environmental damage.

This can potentially lead to larger gas cloud sizes as they would not be limited by the volume of the module as on a fixed topside. This document recommends minimum requirements and guidelines for the design and installation of new piping systems on production platforms located offshore. Remedial actions Retrofit of barriers usually blast walls to existing installations plays a major part in reducing the risk and achieving ALARP criteria for accidental explosion events.
Proceedings of an international conference Oceanology: A key area which requires detailed consideration are the structural details which would perform adequately under static loading but become brittle and possibly fail under a dynamic loading consideration. Some packages can also potentially capture contact, brittle and ductile behaviour of the structure. Duty holders must demonstrate that structures have sufficient robustness to ensure a low probability of catastrophic failure when subjected to accidental explosions.
Publishers Content Coverage Privacy. Also the option of minimising congested areas by splitting up the processing into smaller units and introducing sufficient gaps between the units is unlikely due to space constraints and economics. The failure history of large ocean going vessels is a significant cause of concern in the shipping industry. Full scale tests on realistic modules and congestion confinement levels carried out on joint industry projects have shown that the severity of the threat is more severe and complex than originally envisaged.
Health and Safety Executive. Subsequently, frequency analysis was conducted using parts count methodology to cumulate the frequency of fire scenarios.
