Standardization benefits for megaprojects, illustrated by motor and drive case studies

Presented at OTC 2017, Houston, Texas, USA

The paper provides an overview of Megaprojects, discusses the challenges facing the industry, compares traditional and optimized supply chain approaches and describes the benefits of the Main Motor and Drives Contractor (MMDC) simplification and standardization concept.


The role of standardization and modularization in reducing the cost of subsea electrical connectors

Presented at OTC 2017, Houston, Texas, USA

The focus on this paper will be about presenting real-world experience of design and qualification of connectors based on three case studies, for subsea power distribution, long step out electrical controls, and long step out fiber controls.


Employing micro gas chromats for flare analysis to meet emission regulations

Presented at PCIC Europe 2017

This paper covers the carbon credit concept, an overview of the Grangemouth chemical plants, issues with the original set-up, the new analyser scope and lessons learnt.


Hazardous area motor/drive protection principles and optimum selection criteria

Presented at PCIC Middle East 2017

The paper provides an overview of hazardous area classifications including the implications of the latest IEC standards and the LV/HV motor and drive protection principles of ‘non-sparking’, ‘increase safety’, flame proof’ and ‘pressurized’. The relative advantages for each technique will then be discussed for different scenarios such as atmosphere, overload, starting, inverter operation, size, weight, flexibility and cost.


Turbine replacement by electric drive systems provides significant benefits

Presented at PCIC Europe 2017

Stricter emission regulations, higher process availability, improved fuel utilization and reduction of OPEX costs are some of the reasons to think about alternative ways to modernize oil/conventional turbine trains. All these benefits could be realized by electric drive systems along with additional technical advantages of higher overall efficiency, optimized start and stop conditions and more flexibility for operation by wider speed range. This paper describes in general, the requirements needed to be considered as part of an “overall” solution in order to properly define the final technical concept and capture the technical as well as overall economic advantages.


The consideration and benefits of ethernet based low voltage motor control

Presented at PCIC Europe 2017

This paper presents the latest concepts for motor management using intelligent electrical devices. It starts with the widely accepted concept that smart Motor Control Centers are generally more compact as well as easier to deploy, evidencing why, and builds from this point exploring how the latest generation of devices, their safety and diagnostic capabilities and networking possibilities offer the end user even more technological benefits and opportunities for commercial savings (both in OPEX and CAPEX budgets).

Operational, economic and environmental benefits of electrically driven LNG with a combined cycle power plant

This paper was written jointly by Siemens and Woodside Energy and presented at LNG18 2016, Perth, Australia

The importance of LNG is growing rapidly on a global scale and changes in the market demand innovation in the supporting technologies. The large economic and social benefits of the modern concept come with challenges that will be examined in this paper.


Technical validation and selection of the Siemens Industrial Trent 60 DLE for compressor drive service for the Lake Charles liquefaction project

Presented at LNG18 2016, Perth, Australia

This paper outlines the methodology used and presents the results obtained in the validation and selection of the Industrial Trent 60 DLE aeroderivative gas turbine for the main refrigeration compressor driver service at BG Group’s planned Lake Charles export project in the US.


Into the spotlight

Published in LNG Industry journal, January 2016

The paper looks at how efficient compressor technology can help to decrease costs at the Magnolia LNG project in Lake Charles, Louisiana, US.


Handle with care

Published in LNG Industry journal, April 2016

The demand for safe, efficient and cost-effective compression systems for handling boil-off gas (BOG) in LNG plants, and especially LNG receiving terminals, is greater than ever before. Handling the increasing amount of BOG flow in the traditional way adds unnecessary space, weight and equipment. This paper presents a safe and cost-efficient approach to handling boil-off gas.


All shapes and sizes

Published in LNG Industry journal, June 2016

This paper describes the process for selecting the optimal equipment configuration for the main liquefaction service in small, mid and large scale LNG solutions.


Optimize LNG liquefaction operations through proper refrigeration compressor driver selection

Presented at World Energy Congress October 2016, Istanbul, Turkey

This paper reviews equipment configurations that can be used to drive main refrigeration compressors for given liquefaction processes and discusses the relative benefits of each. It focuses on the power consumption of the main refrigeration island, and compares 10 main driver solutions. It also provides recommendations from an OEM perspective.
