The vessel capsized on Sunday with all 12 crew members still missing.
Twelve crew members of West African Ventures, a contracting firm, working for Chevron Nigeria Limited, CNL, who were missing when the tug boat they were working in sank on Sunday, are still not found.
Chevron management said in a statement that the Jascon-4 tug boat capsized early on Sunday due to “heavy ocean swells” while the vessel was “performing towing operations” at a mooring point around 30 kilometres off oil-producing Delta State.
Reuters quoted an unnamed spokeswoman for West African Ventures as saying on Tuesday that despite rescue operations involving sea divers, “unfortunately all 12 crew members are still missing.”
“Rescue operations are still ongoing and a full investigation into the incident is taking place,” she said.
West African Ventures Limited is an indigenous Nigerian company of Sea Trucks Group, an international group of companies offering offshore installation services to the oil and gas industry worldwide. The Sea Trucks Group, founded in 1977, has over 2,500 workers on its payroll, with offices in Nigeria, Angola, Ghana, United Arab Emirates, the Netherlands, United States, Australia, Singapore and China.
The group also owns and operates a large and versatile fleet of marine construction and supply vessels, large cargo barges, as well as supply bases and fabrication facilities in Nigeria and the United Arab Emirates
