Kribi Power has provided the energy required for an ambitious port development plan in Cameroon, a critical piece in plans for the future success of the country and its neighbours, in a partnership with ABB Turbocharging.
Kribi in Cameroon is justly renowned for its beautiful beaches. The Lonely Planet describes them as the country’s best, noting: “The sand is fine, the water crystal clear, fresh fish is on the menu and cold beer on tap; there are times when Africa hugs you.”
More than a tourist paradise, the town of around 100,000 people has an important part to play in the economic future of Cameroon and its neighbors. A $1.3 billion redevelopment of Kribi’s port is helping to open the regions’ iron ore, cotton and other commodities to global markets, helping Cameroon diversify its exports from oil and easing access to goods from Chad and the Central African Republic.
The projects’ success, however, and with it the future of the region and its 42.5 million residents, is heavily dependent on a reliable and scalable power supply.
This was the herculean challenge facing Gilles Enguene when he was appointed to manage the power plant for the Kribi Power Development Company (KPDC) S.A. in 2017. It was his and his team’s responsibility to ensure that the town and national grid could support the country’s ongoing economic development.
Frequent failure
Kribi Power is a 216 MW natural gas-fired reciprocating engine power plant comprised of 13 Wärtsilä 18V50DF generating sets, that produces roughly a sixth of Cameroon’s southern Grid electricity.
“The major problem we encountered when we arrived at the Kribi thermal power plant about a year and a half ago was the high frequency of engine failures, he said. “The urgency for my staff and I was therefore to analyze the system to identify the necessary levers to eliminate all the factors which could result in downtime and, by association, lost production and penalties. This analysis made it clear that most, if not all, of the time failures were due to damaged turbocharger caused by foreign objects.”
ABB has been servicing the plant since it was commissioned in 2013, but as Pascal Mooh, the head of ABB’s Douala Service Station in Cameroon observed, serving and maintenance was largely conducted on an ad-hoc basis. “Most of the break downs were because of foreign object damage,” he said. “When a turbocharger was damaged, a service team was called out to assess the damage and provide a quotation. Only once this had happened could a purchase agreement be sent in for approval so that we could order parts and send a team out to make repairs or, in the worst case scenario, remove the turbocharger completely and send it in for repair.”
Downtime and penalties
As a result, the repair process caused an enormous amount of downtime for the plant, resulting in significant financial penalties for Kribi Power.
“As my team and I were looking to resolve our continuing power outages, ABB was reaching out to present a solution: The Turbo LifecycleCare Service Agreement concept,” said Kribi Power’s Enguene. “It goes without saying that we had already thought of ABB as a solution provider. Indeed, before Kribi I had managed other thermal power plants, notably the Limbe Thermal Power Plant (82MW) and the Yassa Thermal Power plant (85MW), where I had strong support from the Turbocharging team of ABB. But the LifecycleCare support concept is special. It was tailored and adapted to our specific challenges and needs.”
