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 Proceedings of an International Conference Submersible Technology: The purpose of these recommended practices is to provide information that can serve as a voluntary industry guide for safe well control operations.
The nature of the threat varies significantly with inventory detail, level of confinement and congestion which is almost always present on North Sea layouts. As a result of this, little attention was given to design strategies dealing with explosion scenarios.
Ageing assessments should confirm that structural arrangements are still appropriate for inventory levels that exist on the installation. Introduction Industrial scale fire, explosion and environmental pollution from the production, refining, and distribution of petroleum remains one of the major concerns impacting human life and environment, incurring business losses and jeopardizing organizational reputation.
Structural behaviour under explosion hazards

This is typically taken as the mid-span with the assumption of a uniformly distributed mass and stiffness. The method relies on a aip similarity between the actual and idealised spring mass, which for a beam simply means the velocity and displacement of the spring mass corresponds to a point on the beam which best describes the global behaviour. Worldwide practice Prior to the Piper Alpha incident inlimited design guidance for offshore structures to limit the consequences of fires and rpp existed.

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 Industrial scale fire, explosion and environmental pr from the production, refining, and distribution of petroleum remains one of the major concerns impacting human life and environment, incurring business losses and jeopardizing organizational reputation.
As a consequence there is the potential for an improvement apii QRA models.
Some guidance from onshore petrochemical guidelines existed but this was not always appropriate for offshore applications. International Journal of Impact EngineeringVol.
It emphasizes the need to train personnel in fire fighting, to conduct routine drills, ali to esta Previous research has shown that as the gas cloud increases a runaway length can be reached at which point the overpressure increases significantly. Nature of threat The potential for an accidental release of a hydrocarbon mixture is ever present r hydrocarbon carrying installations and, if ignited, could lead to a serious incident involving loss of 2rb, loss of the asset and environmental damage.
Rock Mechanics Symposium and 5th U. This recommended practice is intended to assist in development of a management program designed to promote safety and environmental protection during the performance of offshore oil and gas and sulphur operations.
Limiting a potential gas cloud size is an important issue in the design phase as well as keeping the design pressures inherently lower generally through design to minimise the effects of an explosion and fire is a key component on an FPSO facility Relevant publications ISO Offshore Structures – General requirements ISO Specific requirements for offshore structures – Part 3: Risk level Large scale testing in recent years has highlighted that significantly higher overpressures can a;i as a result of an ignition of a hydrocarbon in a typical offshore apk with realistic levels of congestion and confinement.
This document recommends minimum requirements and guidelines for the design and installation of electrical systems on fixed and floating petroleum facilities located offshore.
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.
Fire and Explosion Guidance Part 2: Subsequently, frequency analysis was conducted using parts count methodology to cumulate the frequency of fire scenarios. The measures for frequency and severity level are normally based on the size of the inventory and complexity of the process, the level of congestion and confinement and the staffing level of the installation.
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.
Technical policy relating to structural behaviour under explosion hazards
Although an incident of the same magnitude as Piper Alpha has been avoided, there have been fires and explosions which could potentially have led to more catastrophic events. This is of relevance to the offshore sector in relationship to FPSO’s where potentially larger gas cloud sizes could form due to space constraints. Structural elements and systems are used in provision of control and barriers for explosions and are likely to be designated safety critical elements.
