Faced with rising fossil fuel energy costs, container terminals are seeking innovative energy efficiency solutions to reduce energy consumption and emissions. However, many terminals rely on Rubber Tyred Gantry (RTG) cranes still powered by large displacement diesel generators, which are significant contributors to these issues. The Susports project involved unique co-operation between a manufacturer (CRESS), consultant (RHDHV), university (The University of Reading), and a container terminal (Valencia Port Foundation) to investigate a range of solutions.
Following the principles of Royal HaskoningDHV’s 4 Questions, we investigated the issues around RTG electrification (e.g. cable reel, bus bar), Energy Harvesting, Storage & Reuse (e.g. flywheel, supercapacitor or battery), or RTG genset downsizing. We developed the tools to include the majority of RTG cranes and technologies in use today. Tools were also verified through a series of rigorous site trials in Valencia, Spain.
The Outcome – Energy efficiency
The project yielded a number of successes including:
- 40% - 60% annual fuel savings and emission reductions.
- Effective implementation of sustainable energy solutions and energy storage systems through pilot studies.
- A suite of design tools to help our clients reduce operational costs and assess their business cases for the investing in these technologies.
- A developed set of solutions for port operates to consider to reduce their energy costs and mitigate their contribution to climate change. The tools currently focus on RTGs, but could be expanded to other common terminal equipment such as rail mounted cranes, straddle carriers or main cranes.
