Underwater maintainable dry type working cabin

Abstract

The invention relates to an underwater maintainable dry type working cabin. The working cabin comprises a cylindrical pressure-resistant cabin with spherical end sockets at two ends, a butt-joint device is arranged at the top of the pressure-resistant cabin, and the bottom of the pressure-resistant cabin is fixedly mounted on a pressure-weight base through a support; a two-way opening and closingcabin door is arranged on the communication portion of the butt joint device and a cabin body; the cabin wall of the cabin body is provided with an observation window, a wet plug interface and a production line interface; a deck is arranged at the bottom in the cabin body, and an escalator is arranged along the cabin wall of the cabin body from the deck to the two-way opening and closing cabin door; a control cabinet is arranged on the deck; and an oxygen candle, a carbon dioxide absorber and a storage battery pack are arranged in the portion, at the lower part of the deck, in the cabin body.The working cabin is compact and reasonable in structure and convenient to operate, and can provide a dry type normal-pressure working environment for underwater production system equipment and provide a working mode of in-situ repair and maintenance in deep sea. By carrying people inside, arranging the observation window and carrying an underwater acoustic communication module and the like, in-situ observation and monitoring means are provided for an underwater production system, and the working cabin becomes a cooperative control center of unmanned operation equipment of the underwater production system.

Description

technical field [0001] The present invention relates to the technical field of underwater operation devices, in particular to an underwater maintainable dry working cabin. Background technique [0002] The maintenance and repair of the traditional underwater oil and gas production system requires the help of underwater unmanned operation tools such as ROV and AUV supported by the surface mother ship. There are problems such as insufficient underwater operation capability, low operation efficiency, limited operation range and adverse sea weather. The problem is that more equipment needs to be hoisted by surface ships and hoisted to the surface mother ship for maintenance and repair. In addition, traditional underwater production equipment needs to resist the adverse effects of external water pressure, ocean currents, corrosion and other factors, and its production efficiency seriously lags behind that of onshore oil and gas exploitation.
