Offshore operation method of shipborne CTD observer

Abstract

The invention relates to an offshore operation method of a shipborne CTD observer. The offshore operation method comprises the following specific steps: (1) preparing before observation; (2) allowinga scientific investigation ship to arrive at an observation position and starting dynamic positioning; (3) adjusting a balance weight when the CTD observer is put into water; and (4) completing CTD observation. Special winches and cranes on the scientific investigation ship need to be used in the step (1) and the step (4). According to the invention, the technical scheme is adopted, the method hasthe following advantages that the dynamic positioning function of the advanced scientific investigation ship is fully exerted, the offshore operation safety and the traditional CTD profile operationspecification are combined, according to an offshore surface flow field and turbulent flow characteristics caused by rotation of a ship body and a propeller, a method for CTD profile observation of aship body under the condition that the dynamic positioning function is started is creatively provided, the method can effectively obtain high-quality CTD observation data, the ocean observation efficiency is greatly improved, it is guaranteed that reliable observation data are obtained through ocean observation, and the development of ocean research work is promoted.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a marine operation observation method of a direct-reading temperature, salinity and depth instrument on a marine scientific research ship. Background technique [0002] The direct-reading temperature, salinity and depth instrument is a conventional observation equipment for marine surveys. The traditional direct-reading temperature, salinity and depth instrument's offshore observation operation process is formulated according to the characteristics of previous scientific research ships and combined with the safety of offshore operations. In recent years, a number of advanced scientific research ships with dynamic positioning functions have been successively put into ocean observation operations. During the application, it was found that under the operating specifications of the traditional direct-reading temperature, salinity and depth meters, the obtained n...

Problems solved by technology

In recent years, a number of advanced scientific research ships with dynamic positioning functions have been successively put into ocean observation operations. During the application, it was found that under the operating specifications of the traditional direct-reading temperature, salinity and depth meters, the obtained near-sea surface Observational data quality is poor

Direct-reading CTD profile observations are carried out on scientific research ships with dynamic positioning functions. At present, there is no unified industry standard to obtain high-quality offshore surface CTD observation data.
