An external pipeline system for deep-sea supply ships

Abstract

The invention relates to an out-transporting pipeline system used for a deep-far sea supply ship. The out-transporting pipeline system used for the deep-far sea supply ship is characterized in that the out-transporting pipeline system comprises a transporting hose, a transporting outer protecting pipe, a transporting inner protecting pipe, a hydraulic supporting outer pipe, a hydraulic supportingrod and a hose end portion component; the transporting inner protecting pipe is slidably connected with the interior the transporting outer protecting pipe to form a telescopic pipe structure; one endof the transporting outer protecting pipe is connected with a ship board of the deep-far sea supply ship through two rotating bolts; one end of the transporting hose is connected to the deep-far seasupply ship, the other end of the transporting hose penetrates out from the telescopic pipe structure, and the end portion of the transporting hose is provided with the hose end portion component; andthe hydraulic supporting rod is arranged at one end of the hydraulic supporting outer pipe and is controllable in length, the other end of the hydraulic supporting outer pipe is connected with the ship board of the deep-far sea supply ship through the rotating bolts, and the other end of the hydraulic supporting rod is hinged to the lower side of the transporting outer protecting pipe.

Description

technical field [0001] The invention relates to an external transportation pipeline system used for deep-sea supply ships. Background technique [0002] With the continuous expansion of the scale of human development of offshore oil and gas, the main battlefield of offshore oil and gas exploration and development has shifted to the deep sea, and the development of offshore oil and gas resources requires a large , drilling water and living supplies, etc.), currently offshore oil and gas resources development drilling and production materials are generally directly supplied by ships from mainland base wharves, supply ships are limited by the berthing requirements of oil and gas field development facilities, and offshore oil and gas development materials generally use three-purpose working ships, etc. Special ships are used to transport to oil and gas field development facilities, while special ships such as three-purpose work ships have limited voyage and tonnage. Deep sea oi...

Problems solved by technology

The traditional stern transportation system is equipped with hose reels, receiving structures and other devices at the stern of the deep-sea supply ship, which often requires long floating hoses. The system layout is time-consuming and labor-intensive, and the transmission efficiency is low, but the requirements for environmental conditions are not high.

The traditional side-by-side conveying system has high requirements on the environment and is easy to arrange in place. Under certain wave conditions, in order to prevent the ship from colliding or the hose from breaking, it is necessary to interrupt the external transportation, which has a great impact on the transportation operation
