Study on AC interference law of high voltage AC cable to submarine pipeline and safe distance
Materials and Corrosion, 2022In recent years, due to the large‐scale construction of wind power and shore power projects, the amount of submarine high‐voltage AC cables has been increasing year by year, and they often form a “common corridor” in parallel with adjacent submarine ...

Real-Time Detection Method for Submarine Pipeline Leakage Based on Deep Learning and Jetson nano
OCEANS 2022, Hampton Roads, 2022There are many pipelines under the sea to transport oil and natural gas. However, some pipelines maybe leakage under long time exposing to the marine environment, which cause pollution and economic losses.

Buckle propagation in submarine pipelines
Nature, 1975DURING its construction a submarine pipeline is at the same time bent and loaded by the external pressure of the sea. If it is bent too far, it buckles. If the local external pressure is small, the buckle is limited to a short kink on the compressed side of the pipe.

Evaluation for Allowable Span Length of a Submarine Pipeline Considering VIV Hysteresis Effect
International Journal of Offshore and Polar Engineering, 2021Vortex-induced vibration (VIV) is one of the main causes of fatigue failure of submarine pipelines under the action of ocean currents. A reasonable evaluation for the allowable (maximum) length of a pipeline span is vital for the avoidance of VIVs.

Fatigue Analysis for Submarine Pipelines
Offshore Technology Conference, 1982Abstract Purpose of this paper is the presentation of the techniques used in fatigue life forecasts for a submarine pipeline, which have been worked out during the design of the Tran Mediterranean Pipeline. The stress level imposed by supports configuration, pipeline weight, weight-pressure ...

Movements Of Submarine Pipelines Close To Platforms
Offshore Technology Conference, 1981Abstract An analytical model of expansion movements at the ends of pipelines is developed. A comparison with measurements on two North Sea pipelines shows that the analysis is consistent with observed behaviour, and can be used to assess the results of corrective action.

Submarine Pipeline Trenching by Multipass Ploughs
Offshore Technology Conference, 1985ABSTRACT A major development program for large ploughs to trench submarine pipelines began in 1975, and has led to the construction of 13 ploughs, which have been used in many parts of the world. Deep trenches are best cut in a sequence of separate passes.

Hydraulic Trenching of Submarine Pipeline
Transportation Engineering Journal of ASCE, 1971A consortium of oil companies commissioned two firms of contractors to construct, as a joint venture, a single buoy mooring system off the South African coast. It was planned to pull the pipes out to the sea through a sleeve to be placed in a trench blasted 600-ft rocky reef in the surf zone, and to bury the pipe on the seaward side of the reed between

Concrete coating for submarine pipelines
Magazine of Concrete Research, 1982Synopsis A submarine pipeline is usually externally coated with reinforced concrete, the function of which is to protect the corrosion coating against impact damage, and give the pipe additional weight to stabilize it on the sea bed. There are unusual requirements in design and application technology. The paper examines the current state of knowledge
