Study on Guarantee System of Engineering Survey in Far and Deep sea

Ocean engineering activities need to be carried out under the conditions of complete procedures and legal approval documents. However, because of the more complex environment and challenges, it is necessary to establish and improve the investigation and operation guarantee system. By analyzing the types, characteristics and demands of the engineering survey in far and deep sea, the contents and components of its guarantee system were discussed, and explanations on the ship and equipment support, organization and personnel support, offshore communication support, survey implementation scheme guarantee, quality management and control guarantee, HSE guarantee and emergency plan guarantee were given in detail. The construction method and process of engineering survey guarantee system in deep sea, were furtherly illustrated through an actual survey example. It is an important prerequisite for the smooth development and completion of the survey to build a complete guarantee system before the work of engineering survey in far and deep sea starts.
