About this Training Course Liquefied Natural Gas (LNG) has provided intercontinental mobility to natural gas, which now provides about 25% of the global primary energy. Being the cleanest fossil fuel, natural gas/LNG consumption is forecasted to grow in all future scenarios. With the entry of various players, including Trading companies, the LNG value chain is becoming increasingly complex, and a solid understanding of its economics and management of its interfaces have become crucial to identify and assess investment opportunities and risks. Recent market disturbances caused by COVID-19, Oil & Gas price instabilities - coupled with the political (Ukraine/Russia) challenges - make a deep understanding of LNG Value Chain Logistics and Economics even more essential to ensure the security of energy supplies sustainably and profitably. This intermediate level 3 full-day course starts with a concise introduction to the LNG business. Thereafter, the elements of the LNG value chain are described, and their individual economics analysed. A Business Activity Model along the value chain will be developed and discussed in depth, covering the following key processes: 'Buy Gas - Transport Gas - Liquefy Gas - Sell LNG/Products - Ship LNG - Regasify LNG' The integrated chain economics will then be developed and quantified. A hands-on group workshop/exercise developing the economic case of a full-sized Liquefaction project will be carried out, considering the forecasted cash flows throughout the project life, the location of the plant, its markets, project sensitivities and profitability assessment. Participants will be provided with Excel based tools/models (LNG Liquefaction project development Net Present Value (NPV) analyses, Shipping Freight Calculations and Economics) to work through the exercises and also for their future personal use. Training Objectives After the completion of this course, participants will be able to: Understand how the LNG Value Chain operates, bound by the relevant Contracts and Agreements. Learn the basic economic parameters (operating, capital costs, financing, profitability) of each major element of the value chain. Appreciate the complexity of the value chain, and the associated opportunities and risks. Develop quantitative project evaluation skills. Explore options to maximise profitability in a given LNG value chain. Discuss best practices on how to manage, steer and govern these activities. Target Audience Technical, Operational, Shipping, Commercial, Project and Governance professionals who are already active in a specific section of the LNG Value Chain will directly benefit in developing a wider and deeper perspective on how the LNG Value Chain operations and can be optimised. Managers (Technical, Financial, Legal and Governance) less familiar with the specifics of the LNG Industry will also benefit from attending this VILT course, as they will obtain the required background to be able to set sharper targets, suitable performance indicators, and governance and performance assessment guidelines for units engaged in the chain. The course is most relevant for professionals engaged in the LNG industry at: National and International Oil & Gas/Energy Companies LNG Importers/Exporters/Traders/Shippers Government & Regulatory Agencies Finance Institutions It will also apply to the following audience: Business Development Managers Corporate Planning Professionals Project Developers Supply Planners & Scheduling Professionals Regulators Tax & Finance Advisors Compliance Officers Equity Analyst and Bankers Joint Venture Representatives, Board Directors Negotiators and Contracting Staff Trading Professionals Course Level Intermediate Trainer Your expert course leader is an Oil & Gas/LNG professional with more than 35 years of international experience, majority of which was gained at Shell International Joint Ventures engaged in Oil Refining, Supply / Trading, Gas Supply and LNG Businesses in the Netherlands, France, Thailand, Dominican Republic and Nigeria.

As long as they have a Corporate Real Estate department fighting their corner and coordinating and controlling the estate of space they occupy, whether leased or owned. Corporate Real Estate Managers keep an eye on productivity and performance of the entire ‘estate’. Business plans take in short term tactical allocations and long-term structural plans. Corporate Real Estate Managers are essential in enabling a large corporate or governmental occupier to get the most out of the space they occupy. This on-line course gives a solid grounding to those who work in Corporate Real Estate departments for occupiers and service / data / software providers, as well as those who work for investors and want to understand the considerations from the occupiers’ point of view (as occupiers are in fact their tenant, and their main source of income).

About this Training Course  A few decades ago, the purchasing function in an Oil & Gas company was seen only as a procurement function in charge of supplying goods and services defined by the end user. Over the years, the purchasing function has won its letters of nobility and has proven to be a powerful leverage of savings and cost reduction. In the upstream Oil & Gas sector, where production sites are spread everywhere and sometimes in very isolated areas, purchasing & procurement performs an important mission to secure the supply of high-tech equipment which will travel all over the world before being installed offshore or in remote areas. These two objectives, cost saving and securing of supply, make the purchasing & procurement a strategic function and an essential segment of the supply chain as it drives the other steps in the chain.   Training Objectives By the end of the course, the participants will feel confident in their understanding of: The supply chain functions in the upstream Oil & Gas industry and its objectives. The purchasing process from the identification of a need to its satisfaction within the specifications, planning and budget. The strategic tools of the buyer: The category management and market analysis, the definition of the frame agreement and contracts. The creation of value for their organization by using the leverages of the purchasing process from the selection of supplier, the cost analysis and the negotiation. Target Audience This course is primarily designed for purchasers or head of purchasing/procurement. It is also necessary for other stake holders in the supply chain, including expediters, stock controllers and cost controllers. This course is also recommended for the participants in the logistics function who want to enlarge their knowledge domain of the supply chain. Finally, the supply chain administrators from the technical departments may also find this course necessary in order to facilitate their interaction with the purchasing department.
