Petrosab Petroleum Engineering Sdn Bhd (PPESB), a joint venture between KNM Group Berhad and Petrosab Logistik Sdn Bhd is formed to cater to the current and future oil and gas development in Sabah. The joint venture has a manufacturing plant to manufacture process equipment in Sabah, a move apparently mooted to strengthen the development of oil and gas projects that would benefit Sabah in the future.

Through this collaboration, PPESB aims to develop the Sabah Plant into a major hub for process equipment manufacturing which would certainly enhance Sabah in the aspect of job creation, supporting industry, entrepreneur development, technology transfer and human capital transformation. In addition to process equipment manufacturing, the company has also ventured into undertaking EPCC projects in Sabah.
