Shearwater Lines Up Ghana’s First Deepwater OBN Survey
Bottom Node (OBN) seismic survey in Ghana’s Jubilee and TEN fields, operated by Tullow and its partners.It will be the first deepwater OBN project offshore Ghana, following Shearwater’s recent deployment of the SW Tasman vessel and Pearl node OBN platform in Côte d’Ivoire and Angola. The two-month survey is scheduled to begin in the last quarter of 2025.The SW Tasman and Pearl node platform have been continuously deployed offshore West Africa since late 2024, first executing the inaugural OBN survey offshore Côte d’Ivoire before mobilizing to consecutive surveys
ExxonMobil Hires Shearwater for OBN Survey in Angola
Shearwater Geoservices has secured a deepwater Ocean Bottom Node (OBN) seismic survey work offshore Angola by ExxonMobil’s affiliate Esso Exploration Angola Block 15 Limited.The two-month project is scheduled to begin during the third quarter of 2025.The project will be delivered using Shearwater’s OBN platform, featuring the SW Tasman and Pearl node system, with SW Gallien deployed as source vessel.“Being selected by ExxonMobil to perform this OBN survey in Angola is a real testament to Shearwater’s OBN-platform.“This award reflects our strong track-record in delivering
KOTUG Completes SPM Buoy Upgrade for Azule Energy
KOTUG completed the replacement of the bogie wheel and rail system on Azule Energy's Single Point Mooring (SPM) CALM buoy in Angola's Block 18. This buoy, one of the largest of its kind in the world, was installed in 2007 at approximately 1,200 meters. It is the primary export route for oil from the Greater Plutonio FPSO.The key objective for the project was to ensure that the replacement work was carried out without disrupting ongoing oil production and export operations. To achieve this, KOTUG’s team conducted a comprehensive site survey, handled engineering and procurement, and
