A decade-old seismic vessel was refurbished and deployed to serve Japan’s national oil and gas prospecting scheme

Japan Oil, Gas & Metals National Corporation (JOGMEC), a Japanese government institution under the purview of the Ministry of Economy, Trade and Industry, has been tasked with securing energy and mineral resources from the deepsea to satisfy the global hunger for minerals.

The company has already been scouring for mineral deposits on the floors of the Pacific Ocean in Japan’s territory, and has recently added one more seismic vessel to its fleet in its quest to harvest nodules from the deep.

In October 2019, JOGMEC took delivery of Tansa (ex-Ramform Sterling), a 2009-built seismic vessel that was pre-owned by Petroleum Geo-Services ASA (PGS), a Norwegian marine survey company that has been scouring the oceans for oil and gas reserves for oil majors.
