By 2010, the B-series had gone through several development stages, including introduction of gas variants for powergen as well as marine mechanical drive applications. Considering its, then, 25 years technical life span and future challenges in the different markets and applications, an innovation process was started for further upgrades and improvements. The innovation process spawned a concept leading to the first clean sheet engine platform from Bergen Engines in a decade. Increasing the power output per cylinder as well as the power flexibility whilst reducing fuel consumption, emissions and life-cycle costs were obvious targets. A significant amount of time was spent initially, but also throughout the project, to incorporate technical solutions based on feedback and recommendations from owners, operators, service technicians and mechanics. This includes enhanced equipment health monitoring and surveillance systems enabling not only condition-based maintenance and spare part sourcing, but also a minimization of failures and downtime by continuous data acquisition and evaluation. The main focus, however, was given to the engine architecture - the block, cylinder heads, liner and the connecting rod as the engine’s performance is heavily dependent on the successful integration of the power pack elements. In doing so, a sustainable power output of 600 kW per cylinder could be achieved for both in-line and V-, diesel and gas engines at 750 and 720rpm. Moreover, the active use of modern engineering tools and front loading methods allowed for global optimization of the whole engine structure providing improved material utilization in the block and crank shaft as well as add on modules and appendices. The block stiffness was significantly increased resulting in reduction of the vibration and noise levels. At the same time, the original footprint was practically maintained. Another important feature incorporated is the common basic structure shared between all fuel types so that a rebuild from diesel to natural gas or dual fuel can be carried out by switching power packs and adapting the fuel system. This paper focus on the key aspects of this development programme and process and presents an overview of technical and performance data of the first B33:45 in-line diesel engines.
