Simulation based grid compliance
Today, large diesel and gas engines face an abundance of different loading conditions, in both energy production and marine applications. Hence, the importance of being able to accurately analyse these loading conditions is constantly growing. The goal of this article is to introduce the possibilities of coupling electrical and automation system models with flexible multibody dynamics to enhance and optimise the engine design for varying loading conditions. This article is based on the award-winning paper “Simulation Based Grid Compliance,” published at the CIMAC 2016 World Congress by J. Könnö, T. Frondelius, T. Resch and M. Santos-Descalzo. Please refer to that paper for further details on the methodology.

LNG value chain optimisation – Case Myanmar
An optimal logistics chain is the key to making liquefied natural gas (LNG) affordable for the end users and profitable for the LNG solution providers. Due to the number of unknowns in the equation, planning and optimisation can be challenging. However, a case study can help estimate the cost prices of gas for project configuration options and examine the resulting effects.
