An underwater Viable dry working cabin

Abstract

The invention relates to an underwater maintainable dry working cabin, which includes a cylindrical pressure-resistant cabin with spherical heads at both ends, a docking device on the top, and a bottom fixed on a ballast base through a bracket; the docking device There is a two-way opening and closing hatch at the connection with the cabin; the bulkhead of the cabin is equipped with an observation window, a wet plug interface and a production pipeline interface; the bottom of the cabin is equipped with a deck, along the bulkhead of the cabin, from the deck to the two-way There is an escalator at the opening and closing hatch; there is a control cabinet on the deck, and oxygen candles, carbon dioxide absorbers and battery packs are installed in the cabin below the deck. The invention has a compact and reasonable structure and is convenient to operate, and can provide a dry normal-pressure working environment for underwater production system equipment and a working mode for in-situ deep-sea maintenance and repair. It can provide in-situ observation and monitoring means for the underwater production system through internal manning, setting up observation windows, and carrying underwater acoustic communication modules, etc., and become a collaborative control center for the 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.
