Mermaid Maritime Public Company Limited has expanded its overseas footprint with the establishment of Serikandi Mermaid SDN BHD, a new joint venture in Brunei.

The company has been formed to support offshore transport and installation, IRM, decommissioning, and pipeline-related projects in Brunei. Mermaid Subsea Services (Thailand) Ltd. owns 50% of the venture, while the other 50% is held by Serikandi Oilfield Services SDN BHD, a Brunei-based energy services provider.

Mermaid Maritime Public Company Limited said the investment is being financed through internal resources.

The Brunei move follows two recent overseas joint ventures. In August 2025, Mermaid Maritime Public Company Limited set up a Taiwan joint venture with ATE Energy International to provide energy technical services, cable installation, and offshore construction work. In November, the company also announced a joint venture in Equatorial Guinea with GEPetrol S.A., focused on oil and gas services, including diving, vessel supply, ROV support, and related activities.
