Abstract:
The Wärtsilä 32GD engine is a stationary turbocharged “Gas-Diesel” engine which can operate on gas and oil fuel. The direct high-pressure gas injection is applied in this engine. The sophisticated control system of the engine allows operation on gas and oil fuel with very wide range of gas/oil fuel ratio which provides a unique flexibility of fuel usage. The Wärtsilä 32GD technology offers possibility to use good quality gas or heavier gases i.e. with high content of heavier hydrocarbons. The Wärtsilä 32GD engine development and the most important components of the Wärtsilä 32GD engine are presented. The working principles, operation mode, the engine performance and emission levels are described in the paper as well. The paper includes also specification for gas and oil fuels that can be used for the engine operation. The paper is concluded with some typical applications, reference installation and experience from running the engines on challenging fuels.

Abstract:
We present a methodology for systematically using an SPDM platform as the cornerstone of product development. The target is to base product development on clearly defined targets and requirements in different phases of the product development lifecycle. This is achieved by means of a data-centered approach where all data is retained in a digital form in the platform. Instead of reporting, users are provided with different views to the same data. We will demonstrate how a static document-based validation system can be replaced by a common validation data platform. In addition, we aim to base the validation requirements on a reliability analysis workflow. In this case, the platform is used not only to handle the simulation data but to encompass the whole product validation scope. To this end, we show how to couple requirements to the simulations and handle all the design decision data together with the simulations and use these to drive the design. In addition, we present ways to replace simulation reports with dynamic dashboards. To complete the loop, we touch the topic of PLM integration as a tool for assuring completeness of validation data in the product lifecycle. The motivation for the activity is a dramatic reduction in product development time based on a possibly somewhat longer concept phase but less iterations during the detail design phase. We will also present decision making based on data stored in the platform as well as demonstrate the data-centered approach to validation data. In addition, other benefits such as the re-use of data and simulation workflows along with the automatically handled data management are demonstrated. To conclude, some end user opinions and experiences in adopting a new system will be presented. Future developments will include moving also the physical testing data and coupling that with the corresponding simulations and validation requirements.

Abstract:
The aim of this thesis is to critically examine and analyze multi-national corporation´s work with corporate social responsibility when it comes to environmental protection and sustainability. This study is therefore a case study, where empirical material about a multinational corporation, the company of Wärtsilä, is studied. These include annual sustainability reports and other official material available, as well as qualitative interviews with eight employees at Wärtsilä. This material is then analyzed through the theoretical framework of Corporate Social Responsibility (e.g., Caroll, 1979) and through the theory of Corporate Citizenship (Mirvis and Googins, 2006). The results show that Wärtsilä has come far when it comes to integrating and improving its product environmental performance, but there appears to be inconsistencies between the information collected from the reports etc. and the information gathered from the interviews. These inconsistencies show that there is a need for further integration of the goals for environmental protection and sustainability, presented in the official material, into all levels and departments of the company.

Abstract:
An experimental study is carried out to investigate the combustion process in a Wärtsilä 34SG spark-ignited lean burn four-stroke large bore engine (bore 340 mm) by means of optical diagnostics when operating on natural gas. The main focus of this work is to gain knowledge about in-cylinder combustion phenomena when igniting a lean air/fuel mixture with pre-combustion chamber induced jets. Especially the origin of cyclic variability is of interest. The flame propagation process in a single cycle was captured using a high speed video camera. The analysis is based on apparent heat release rates in the pre-combustion chamber and main chamber, in order to find correlations with the imaged phenomena. The results show that the flame propagation inside the main chamber starts at the end of the pre-chamber combustion heat release and that variation in main chamber heat release does not correlate with variations in the pre-combustion chamber.

Abstract:
Abstract Large bore marine engines are a major source of fossil fuel consumption in the transport sector. The development of more efficient and cleaner marine engine systems are always required. Exergy analysis is a second-law based approach to indicate the maximum amount of work obtainable from a given system. In this study, an exergy analysis is used to identify losses and improvement potential of a large bore Wärtsilä 31DF four-stroke marine engine system with two-stage turbocharging. An exergy-based framework is implemented on a calibrated 1D engine model to view the evolution of exergy flow over each engine sub-system while operating on different load points fuelled with natural gas and diesel separately. The overall distributions of engine energy and exergy are initially compared at a systematic level regarding the impact of fuel mode and operating load. Furthermore, the engine irreversibilities are characterized as three types: combustion, heat dissipation, and gas exchange losses. The first type, combustion irreversibility, is the largest source of engine exergy losses amounting to at least 25% of fuel exergy. A crank resolved analysis showed that premixed gas combustion produces lower exergy losses compared to diesel diffusion combustion. The second type, thermal exergy transferred and destroyed by heat losses, are summarized for the entire engine system. From the exergy view, the charge coolers present an opportunity to recover about 9% of the brake power at full load. The last type, gas exchange losses, are categorized by accounting the flow losses caused by the valve throttling, fluid friction in pipes and the irreversibility of the two-stage turbocharging system. Most of exergy destruction in gas paths occurs at turbocharging system, where the high pressure turbocharger contributes to around 40% of the total flow exergy destruction.

Abstract:
Maritime transportation is a significant contributor to SOx, NOx and particle matter emissions, even though it has a quite low CO2 impact. New regulations are being enforced in special areas that limit the amount of emissions from the ships. This fact, together with the high fuel prices, is driving the marine industry towards the improvement of the energy efficiency of current ship engines and the reduction of their energy demand. Although more sophisticated and complex engine designs can improve significantly the efficiency of the energy systems in ships, waste heat recovery arises as the most influent technique for the reduction of the energy consumption. In this sense, it is estimated that around 50% of the total energy from the fuel consumed in a ship is wasted and rejected in fluid and exhaust gas streams. The primary heat sources for waste heat recovery are the engine exhaust and the engine coolant. In this work, we present a study on the integration of an organic Rankine cycle (ORC) in an existing ship, for the recovery of the main and auxiliary engines exhaust heat. Experimental data from the operating conditions of the engines on the M/S Birka Stockholm cruise ship were logged during a port-to-port cruise from Stockholm to Mariehamn over a period of time close to one month. The ship has four main engines Wärtsilä 5850 kW for propulsion, and four auxiliary engines 2760 kW used for electrical consumers. A number of six load conditions were identified depending on the vessel speed. The speed range from 12–14 knots was considered as the design condition, as it was present during more than 34% of the time. In this study, the average values of the engines exhaust temperatures and mass flow rates, for each load case, were used as inputs for a model of an ORC. The main parameters of the ORC, including working fluid and turbine configuration, were optimized based on the criteria of maximum net power output and compactness of the installation components. Results from the study showed that an ORC with internal regeneration using benzene would yield the greatest average net power output over the operating time. For this situation, the power production of the ORC would represent about 22% of the total electricity consumption on board. These data confirmed the ORC as a feasible and promising technology for the reduction of fuel consumption and CO2 emissions of existing ships.
