Battery 3 Recovery Works
Otto Simon Ltd • April 4, 2016
Otto Simon is currently delivering a ‘Hot Idling and Recovery’ Project on ACO Battery 3
The project is due for completion in the summer of 2016 and involves a complex scope of work that includes:
- Replacing all ascension pipes and Pullman valves
- Replacing both north and south flare stacks
- Replacing charge holes
- Replacing door frames and tie-bars
- Replacing a proportion of buckstays
- Quoin end repairs
- Essential maintenance repairs (including replacement of flues and silica welding of all joints and cracks
- Replacing service pipework
- Replacing the walkway above the collecting main
- Electrical and control infrastructure improvements
The project faces the challenge of constantly balancing the needs of pushing coke, continuing the recovery work on battery 3 and managing interfaces between batteries 1, 2, and 4. Paul Hudson, Project Engineer Coke Making Recovery, told InSite Magazine about the complexity of the project: “We need to keep the ovens to temperature throughout the entire project to protect the oven brickwork.” Despite the fact that the battery was ‘hot idled’ from the second week in December 2015 to ensure that it had cooled down sufficiently to start work in the new year, the battery remains a very high temperature intensive environment for Otto Simon’s specialist maintenance engineers to work in.
OSL is continually improving our systems of working and implementing lessons learned throughout the project. Steve Potter, Otto Simon’s Site Manager said that although Otto Simon has encountered some ‘obstacles’ in the project, none have been insurmountable and that with the cooperation of the shift teams, we have managed to achieve more than we had planned. “I’d like to thank the ACO project team who continue to assist where needed in keeping the project moving and helping with resource when possible,” he added.
Stuart Cadzow, Manager of Health, Safety & Environment told InSite Magazine: “I was encouraged by the thought and energy that has gone into this project by the ACO team and Otto Simon Ltd to develop the safe systems of control necessary for a task of this scale and complexity.
All 33 ovens are due to be delivered back to service on schedule.

Presenting at Energy Storage & Hydrogen Solutions Last month, our Head of Consultancy, Clare Dunkerley, was invited to speak at an event in Cyprus, hosted by Ideopsis and the British High Commission Nicosia. The Energy Storage & Solutions Conference brought together leading experts, policymakers, and industry players, with the aim of to fostering dialogue, sharing expertise, and catalysing action towards a more sustainable, resilient, and low-carbon future. The conference attracted some esteemed speakers, including introductory addresses from the Deputy High Commissioner, Adam Sandbrook and the Minister of Energy, Commerce and Industry, George Papanastasiou. The programme was split into 2 sessions with the first highlighting the future of energy storage, moderated by Dr Alexandros Charalambides from the Cyprus University of Technology. Staveros Stavrinos, the Executive Director of the Transmission System Operator Cyprus, explained the issues the Cyprus Energy Transmission System faced, concentrating on curtailment of renewable solar power. Michael Toumbas, of EV power Ltd, shared innovative thinking around an AI enabled electric vehicle local grid power sharing mechanism. There were also great presentations from smart grid expert Dr Andreas Procopiou and the Cyprus Energy Regulatory Authority. The second session concentrated on hydrogen solutions. Dr Andreas Poullikkas delivered on future energy systems while Charles Purkiss updated us on the latest developments at ITM Power. Jeremy Bowman, from Hypermotive Ltd, discussed hydrogen technology for transport and Philippa Oldham shared some work from the Advanced Propulsion Centre. An interesting Q&A session was chaired by Dr Nestor Fylaktos of the Cyprus Institute. Clare presented ‘A Safe Hydrogen Future’, addressing the importance of public perception and the imperative for no major incidents. Clare shared her experience from working on hydrogen projects and provided an insight in how to use the current UK regulatory framework in conjunction with industry codes and standards to demonstrate that risks in hydrogen projects were acceptable to all concerned. It was a fascinating conference providing a fantastic insight to the current and future energy situation in Cyprus, with plenty of time for networking and discussing hydrogen solutions and projects with all the attendees. Our thanks go to Ideopsis and the British High Commission in Nicosia for the invitation and opportunity to participate in the discussions.
