Swire Pacific Offshore has been the victim of a cyberattack, which involved its IT systems being hacked.

Unauthorised access of the Singapore-headquartered marine and offshore contractor has resulted in the loss of some confidential proprietary commercial information and some personal data, it admitted last week.

Swire has “taken immediate actions to reinforce existing security measures and to mitigate the potential impact of the incident”, which did not “materially affect” its global operations.

“We have reported the incident to the relevant authorities and will work closely with them in relation to the incident [and we are] contacting potentially affected parties to inform them,” Swire said.

The company added it is working closely with data security experts to investigate the incident and determine what further action will be needed, and it will take all necessary steps to protect its customers and staff, now and in the future.

Swire provides services including anchor-handling, towing and supply support for offshore drilling and production campaigns, pipelay and construction support. It also provides wind-farm installation and transportation and decommissioning services through its associated company Cadeler, which is listed on the Oslo Stock Exchange.

“Given the active investigations, it would be inappropriate to make any additional comments at this time,” Swire said.

Established in 1975, the company owns and operates a diverse fleet of more than 50 vessels, including anchor-handling tug supply vessels, platform supply vessels and a seismic survey vessel. Swire operates vessels in all global exploration hotspots except the US Gulf of Mexico.
