Ghana: Tullow modernises its operations with a French digital solution.

Tullow Oil, an independent energy company operating in West Africa, has announced a strategic partnership with Opsealog, a French provider of maritime digitalisation and fleet performance management solutions. The agreement aims to modernise Tullow’s maritime operations in Ghana.

As part of the collaboration, four platform supply vessels (PSVs) and anchor-handling tug supply vessels (AHTS) operating at Ghana’s offshore oil fields will be equipped with Opsealog’s advanced technology. Its Streamlog electronic reporting system and Marinsights data and performance integration platform will enable precise vessel monitoring and provide key data to optimize fuel use and reduce greenhouse-gas emissions.

Samuel Kwesi Dickson, Tullow’s Logistics Manager, highlighted the importance of the partnership:

“This partnership with Opsealog marks an important step in the digitalisation of our maritime operations, giving our teams granular, data-driven insights to improve fleet performance and reduce our environmental footprint. The ability to use data to assess, report and improve our efficiency is essential to our strategic vision of building a better future through the responsible development of oil and gas in Africa.”

Integrating Opsealog’s solutions will also make it easier to produce automated weekly, monthly and annual reports on maritime activities. Automation will ensure more accurate data collection while eliminating duplication. Tullow will also be able to monitor key indicators more effectively, including fuel and freshwater levels and crew certificate management.

Briac Lemée, Opsealog’s Business Development Manager, said:

“This project is an excellent example of how data and energy-efficiency expertise can work together to achieve sustainability goals. It gives Tullow Oil Ghana’s onshore teams the right data to deliver high-value analysis and inform strategic decisions that improve asset utilization.”

Tullow Oil currently operates two major oil fields in Ghana: Jubilee and TEN. Production at Jubilee began in 2010 with the Kwame Nkrumah MV21 floating production, storage and offloading vessel (FPSO), while the TEN field came on stream in 2016 with the TEN FPSO.

In December 2024, Tullow Ghana booked the Noble Venturer drillship for a drilling campaign due to begin in May 2025. The $171 million campaign will include six firm wells and is expected to last 360 days.

At the same time, Tullow Oil was involved in preliminary discussions with Kosmos Energy about a possible share purchase offer. On 17 December 2024, however, the two companies confirmed that negotiations had ended and that any acquisition plans had been abandoned.

Through this innovative partnership with Opsealog, Tullow Oil is reaffirming its commitment to improving the performance of its maritime fleet while continuing to reduce its environmental footprint. The initiative is part of a broader digital transformation strategy aimed at strengthening the company’s long-term operational efficiency.
