The research vessel Tan Kah Kee (R/V TKK) returned to the Gaoqi Port Area of Xiamen Port after completing its first mission in 2026. During the voyage, the crew and technicians conducted performance tests on geophysical and biochemical sensing equipment and carried out sea trials for two new systems.
The mission marked the formal acceptance of a deep-sea deck safety support system and a compact Remotely Operated Vehicle (ROV). These additions expand the vessel's technical capabilities for high-voltage subsea operations and shallow-water research.

The newly integrated deep-sea safety system consists of a plug-and-play connector and a surface power monitoring station. Designed for compatibility across different research vessels, the system delivers up to 200 kilowatts of output power. It can adapt to varying electrical inputs to provide up to 5,000 volts (V) alternating current (AC) or 800 V direct current (DC), supporting heavy sampling tools and large-scale ROVs.
The vessel's suite now includes a compact ROV rated for depths of 500 meters. The unit is designed for rapid deployment and can operate in coordination with the R/V TKK or independently from smaller craft. This equipment is intended for high-resolution underwater observation in complex coastal environments, as well as inland lakes and reservoirs.
