Abstract: Combined with the needs of exploration and development of deep-sea oil and gas fields in China，deep-sea bucket foundation installation equipment prototype was premised and manufactured.In the premise of ensuring the pressure，sealing，the size and the mass of the prototype was required to be minimized，and the function of the prototype was ensured to be proper.By using the similar geological sand materials of the South China Sea，15 MPa high pressure test of prototype was finished to ensure that the equipment might work in the deep sea environment.Experimental data was recorded and summarized as follow：penetration function of the bucket foundation is realized with the displacement of 11.23 mm and the displacement accuracy is as 1 mm.The maximum inclination of X axis is as -1.24° and the maximun inclination of Y asis is as 0.91° and the inclination accuracy is as 0.1°.The experimental processes are stable and meet the technical requierments.
