Platform blowing

Platform blowing n. A special technique for blow molding large parts. To prevent excessive sag of the massive parison, the machine employs a table that after rising to meet the parison at the die, descends with the parison, but a little more slowly than the parison, so as to support its weight, yet not cause buckling. 

To recover oil from the continental shelf of arctic Canada and Alaska, drilling and production platforms must be built some miles offshore, in roughly 40 m of water. This is not a great depth, and would present no new problems were it not that the sea freezes in winter to a depth of around 2 m. Wind blowing across the surface of the ice sheet causes it to move at speeds up to 1 m s pressing it against the structure. Ice is...

The best way of handling this problem is to place the generators and helideck at the opposite ends of the platform or rig, with the prevailing wind blowing the exhaust plume out to sea away from the incoming helicopter, as shown in Figure 9.12. 

H2S is generally removed from the produced gas streams on the platform. If it is not removed it not only presents a hazard to workers downstream, but can also corrode equipment. The H2S is normally removed through the use of an amine system. The removed H2S is then burned in the facility s generators, creating sulfur dioxide (SO2) which is then discharged into the atmosphere (and which can create a health hazard if the exhaust blows back on board or to another platform). 

JM McDonald found the wind was blowing from the south. He used his knowledge of the platform to find his way to the southwest comer, where he climbed down a hose before dropping into the sea. 

Oil and gas blow-out incident on offshore platform. Considered one of Australia s worst oil disasters. Well continued leaking until 3 November 2009, in total 74 days.

Offshore facilities pose critical questions of personnel evacuation and the possibility of total asset destruction if prudent risk assessments are not performed. A thorough analysis of both life safety and asset protection must be undertaken. These analyses should commensurate with the level of risk a particular facihty represents, either in personnel exposed, financial loss, or environmental impact. An unmanned wellhead platform might only require the review of wellhead shut-in, flowhne protection, and platform ship collisions to be effective, while manned drilling and production platforms require the most extensive analysis. Generally the highest risks in offshore facilities are drilling blow-outs, transportation impacts, and process upsets. Where inadequate isolation means are provided for either wellheads or pipeline connections to the installation, considerable fuel inventories will be available to an incident. 

Abstract. This work introduces the design of a multimodal application allowing the user to sculpt 3D medical data. We are considering interaction modalities such as blowing and gesture to segment the 3D data visualized. Besides we present a multimodal platform for the rapid development of multimodal interactive systems as a central tool for an iterative user-centered design process. 

The drillfloor and the derrick (drilling tower), with pipe handling systems and the flare tower on the top, are located in the centre of the platform. In this area, we find the remaining systems, for drilling and mud treatment. Subsea equipment such as valve assemblies (X-trees) and blow-out preventer (BOP) are stored and handled in the moon-pool area below the drill floor. 

Major accidents involve the accidental release of considerable energy and the potential for multiple fatalities and major material damage. In offshore oil and gas production, there are a few types of hazards or energies associated with the risk of major accidents. For a floating PDQ platform, they include fires and explosions due to rupture of process containment, blow-out or maritime accidents (hull puncture due to ship collisions, dropped objects, extreme weather or ballasting errors). We will here focus on the prevention... 

The location of the subsea wells underneath the platform, which means that oil and gas will reach the sea surface under the platform in case of blow-out. 

According to the results of the REPA, the anchor-release system of the semi has to be designed such that the platform can withdraw to a safe location outside a burning pool fire on the sea surface in case of blow-out. The risers and substructure have to be protected. The derrick must be able to withstand a burning blow-out during the time it takes to relocate the platform to a safe position outside the pool fire on the sea. With these measures, the semi is considered feasible. 

The contractor updates the REPA to include the results of concept optimisation. Norskoil s project SHE manager supervises this work. It is shown that the concept meets all appUcable acceptance criteria, provided that a number of assumptions are met. These define the accidental loads from fire, explosion, dropped objects and ship collisions that the semi mnst be able to withstand. Another set of assumptions defines the safety and communication systems that have to be operable during an accident. There are also assumptions regarding the collision warning system and the withdrawal of the platform from the snbsea wells in case of blow-out. The REPA also results in a number of recommendations based on the ALARP principle. The assumptions and recommendations serve as input to design development and to specifications and need to be followed up in later project phases. 

ISAR, the International Society for Aeolian Reseach, launched a new journalAeoZi a Research in January 2009 which will include papers that address fundamental studies of the physics of blowing sand and dust and the deposition of sediment. Practical apphcations including environmental impacts and erosion control will be covered as well. The objective of the journal is to offer a single platform for papers dealing with aeolian processes which are presently published in a wide variety of journals. Research articles, case histories, short communications, book reviews, thematic issues and review articles will be included in the journal. ... 

H2S is then burned in the facility s generators, creating sulfur dioxide (SO2), which is discharged to the atmosphere and can create a health hazard if the exhaust blows back on board or to another platform.
