Abstract:

Subsea production system is widely used in the development of offshore oil and gas resources, and always runs at the position of subsea mud line for a long period. In order to ensure safe operation and reduce the structural complexity as well as the maintenance cost of equipment, it is necessary to equip a highly reliable subsea pressure and temperature transmitter (PTT). So far, the design and manufacture technology of subsea PTT has not been developed in China. On the basis of fully realizing the localization of subsea production system, and planning the industrial distribution of subsea key equipment from technical commanding point, this paper analyzes the technical status of PTT comprehensively. Firstly, the engineering background, the installation position of PTT and its key role in subsea production system are introduced. The working principle of PTT is described as well. Afterwards, the function and technical requirement of the relevant standards for PTT are illuminated. The mechanical structure, component material, power supply, communication, pressure-temperature transmitter precision, resolution and other data parameters are compared and analyzed as well. Finally, the technical difficulties, the problems faced by international procurement, along with the urgency and necessity of localization of  PTT are presented with summary and prospect.
