Since oil phase materials, oxidizer, and water are important components of emulsion explosive, their influences on compression resistance performance of emulsion explosives in deep water was studied by using reusable experiment device to simulate the deep charging environment. The experimental results show that with the equivalent content of the oil phase material, the sequence of three oil phase types of emulsion explosives from good to bad in terms of compression resistance performance and explosion performance in deep water are composite wax, composite wax and machine oil, paraffin wax, vaseline and machine oil. With the equivalent content of oxidant, the type of oxidant species has quite small influence on compression resistance performance and explosion property. Within a certain range, water content has small influence on compression resistance performance, and explosion performance increases with the increasement of water content, while it significantly decreases with water content increasing to a certain amount.

compound sensitizing agent is an important component of the emulsion explosive, by using reusable experiment device to simulate the deep charging environment, study compound sensitizing agent on the properties of emulsion explosive deep water pressure resistance. Experimental results show that the mixed sensitizing, the deep water pressure resistance of three kinds of emulsion explosive performance award to him a bad order: glass microspheres + perlite + sodium nitrite sensitization, glass microspheres + perlite and sensitizing sodium nitrite sensitization. Compound containing glass microspheres sensitizer, the measurement of explosive performance closer to sensitization performance when only glass microspheres, perlite, the addition of sodium nitrite on the explosive performance contribution is small. Sodium nitrite and perlite mixed sensitizing, explosive detonation "hot spots", first class formation is chemical sensitization is given priority to, only a minority of perlite as "hot spots", the measurement of explosive performance closer to use sodium nitrite sensitization performance.

Among the compliant platforms, TLP is a vertically moored structure with excess buoyancy, used for deep water oil exploration. In this structure tethers can be tensioned to such an extent that heave, roll and pitch motions of the platform induced by ocean waves are virtually eliminated. SeaStar is new generation of mini tension leg platforms which is similar to a spar and has favorable response features of a TLP. This paper illustrates the results of experimental work performed on a 1/100 scaled model of SeaStar TLP in a wave flume. The study refers to the induced tension in different tendons of the model and the motion response behaviour of the model on different degrees of freedom under several directional impinging random water waves. The results are presented in the frequency domain and the response amplitude operator for each motion of the platform has been calculated.
