Under the Chuan Hup Group, involvement in the oil and gas industry began in the early 1970s in Indonesia, the largest oil producer in South East Asia. In the early 1970s, oil exploration and production activities started onshore with major customers being Caltex Indonesia in Sumatra, Tesoro in Tarakan and Unocal in Balikpapan. As oil production progressively moved offshore, our involvement increased to meet demand and requirements of the oil customers. The consequential rise in demand for offshore support services led to an expansion to our offshore fleet. From 1981 to 1983, we acquired a total of 24 units of AHTS and maintenance vessels plus one tender assisted work-over rig.
