Crisis Management Plan

ABSTRACT U.S. federal and state regulations require industry to develop and maintain detailed crisis and emergency response plans. These plans are, for the most part, well thought out and detailed. As a result, along with extensive training and exercise programs, industry preparedness is better than it has ever been to respond to and manage an emergency. But how well prepared is industry to handle the business or operational continuity aspects of a crisis or emergency? What plans are in place to deal with the requirement for continuing essential business functions in the face of a disaster? If a major incident occurs to a refinery, terminal, or offshore production platform that requires it to be taken off-line, or damages it beyond repair, are there plans in place to minimize the impacts on the rest of the organization and on the downstream customers? How will this be done simultaneously while managing the response? This paper addresses those needs and discusses the requirements that companies in the oil and chemical industry should consider in developing business and operational continuity plans. It explains a multi-step planning process that is being used by many companies around the world to maintain their business edge when a crisis or disaster strikes. This planning process includes such functions as conducting a risk analysis and business impact analysis, developing mitigation and recovery strategies, drafting a continuity plan, developing an awareness program, and building a training and exercising program. The paper also looks at the similarities between business and operational continuity plans and a company's emergency or crisis management plan and address ways in which the plans may be integrated.

A diode rectifier-modular multilevel converter AC/DC hub (DR-MMC Hub) is proposed to integrate offshore wind power to the onshore DC network and offshore production platforms (e.g., oil/gas and hydrogen production plants) with different DC voltage levels. The DR and MMCs are connected in parallel at the offshore AC collection network to integrate offshore wind power, and in series at the DC terminals of the offshore production platform and the onshore DC network. Compared with conventional parallel-connected DR-MMC HVDC systems, the proposed DR-MMC hub reduces the required MMC converter rating, leading to lower investment cost and power loss. System control of the DR-MMC AC/DC hub is designed based on the operation requirements of the offshore production platform, considering different control modes (power control or DC voltage control). System behaviors and requirements during AC and DC faults are investigated, and hybrid MMCs with half-bridge and full-bridge sub-modules (HBSMs and FBSMs) are used for safe operation during DC faults. Simulation results based on PSCAD/EMTDC validate the operation of the DR-MMC hub.

Renewable energies became more and more important in the last years. Hydrogen as a promising energy carrier is a perfect candidate to supply the energy demand of the world. The state of the hydrogen gas (turbulences and point concentrations) has a significant impact on the gas explosion indices. A gas cloud is formed by a partial-pressure method in gas explosion experiments in the spherical 20.0∙10-3 m3 chamber. Gas in the chamber reaches an uniform state beyond in hundreds of ms. The absolute pressure for gas dispersion should be higher than 0.01 MPa for the H2 of concentration larger than 30 vol. % of fuel. The initial temperature also influences turbulent gas flow before ignition, especially in the case of the gases lighter-than-air.

AbstractLomond is a gas–condensate field on the east flank of the Central Graben UK Continental Shelf, some 230 km east of Aberdeen in Block 23/21. The field was discovered in 1972 and was developed with nine production wells from an integrated production platform. Lomond is a large salt-induced anticline with four-way dip closure. The reservoir comprises Paleocene turbidite sandstones with the majority of the hydrocarbon volume in the Forties Sandstone Member and the top seal is provided by laterally extensive mudstones of the Sele Formation. The field is structurally compartmentalized with three different hydrocarbon–water contacts, but with the gas leg in pressure communication. Significant reservoir and structural complexities are observed in Lomond Field; however, the production behaviour exhibits classical tank-like depletion behaviour over its production history. With a very high recovery factor to date, the field has produced 883 bcf or 86% of the gas resource initially in place.
