Offshore fixed platforms and wellhead platforms are the major elements of Vietsovpetro JV fields construction at offshore Vietnam. They provide gathering and treatment of oil, received from producing wells following transportation to FSO by means of subsea pipelines. Field construction with wellhead platforms and central processing platform allow avoiding significant capital investment for mounting the metal-consuming fixed platforms with multi-purpose topside and, consequently, reducing the operating costs. Vietsovpetro development trajectory in terms of capital construction aims on reducing the metal consumption and expenses. Optimization of construction solutions and shift to unmanned wellhead platforms technologies resulted in cost reduction more than twice comparing to 2014. Nowadays, the most prioritized Vietsovpetro offshore facilities are unmanned and satellite wellhead platforms. In order to minimize investment costs on wellhead platform construction while producing from marginal fields with low recoverable reserves it is required to construct and operate a fundamentally new type of the offshore facilities – mini wellhead platforms. Such Mini-WP consists of uninhabitable platform with minimal set of processing equipment, required for operating 6-9 wells.

The article covers the main aspects of developing the wellhead platform designs and construction, potential participation in the new innovating projects for engineering and operating the marginal fields, as well as construction of renewable energy source objects.
