TorcSill and its AnchorPipe TEAM designed and installed helical anchors to provide offshore buoyancy control and stabilization for various pipelines at two pipeline crossings in the Gulf of Mexico. The owner required a method to stabilize its pipeline at two nearshore pipeline crossing locations, at which the pipelines would be subjected to buoyancy, current, wave and other hydrodynamic forces. In addition to the engineering challenges, project schedule, budget, safe future pipeline operating conditions and an anchoring foundation design life of at least 50 years were factors in the material design and construction planning. Design and manufacturing required custom clamp fabrication to accommodate and secure up to 3 pipelines bundled together. For the safest and most efficient installation, TorcSill utilized a vessel-mounted crane rigged to its unique twin-drive anchor installation system designed to install a complete anchor set two helical anchors and pipeline clamp in a single approach.

Pipeline transport

Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes —a pipeline—typically to a market area for consumption. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills , or where canals or channels are poor choices due to considerations of evaporation , pollution , or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks.

By Qiang Bai and Yong Bai. Because of rapid advances in the medical sciences, in particular, independent verification of diagnoses and drug dosages should be made. Summary: Subsea pipelines are used for a number of purposes in the development of subsea hydrocarbon resources as shown in Figure 1. Normally, the term of subsea flow-lines is used to describe the subsea pipelines carrying oil and gas products from the wellhead to the riser base; the riser is connected to the processing facilities e. The subsea pipelines from the processing facilities to shore are called export pipelines, while the subsea pipelines from the platform to subsea equipment used to transfer water or chemical inhibiters are called water injection or chemical flow-lines -- Provided by publisher.

Kamyshev, M. Development of offshore oil and gas fields involved the necessity of installation of multiple underwater pipelines to transport oil and natural gas. In the past intensive research has been conducted in the USSR into various theoretical and practical aspects of the marine pipe line construction. This paper presents the results of experimental studies of hydrodynamic and kinematic behaviour of the marine pipelines. The basic laws are considered of the pipeline hydrodynamic resistance in the process of its towing for different installation methods: from the sea surface and by a submerged method in a broad variety of the pipeline design. A method is suggested to assess the pipeline tow resistance in calm water and in the rough sea. A new pipe string towing technique is considered allowing to reduce the sea wave effects by means of pipeline submersion in the process of its towing.

Trend of the environmental supervision on submarine pipeline installation

Submarine pipelines are indispensable for marine oil and gas transportation and water supply to islands. They have been used to transport oil, gas, oil-gas mixture, or water Qu et al. Construction method is very important for costly and time-consuming marine pipeline installation and should be selected after an overall consideration of technique, capital, and time Wang et al. Moreover, the environmental impact and safety of construction, and its impact on the surrounding marine exploitation are also determinants. Besides common laybarge and tow methods Sun , subsea pipelines can also be installed by horizontal directional drilling HDD , shield tunneling, and mine tunneling Wei et al.

Stopping the production, heavy loss and environmental hazards are the outcomes of damaging the offshore pipelines. Several cases of damaging because of fishing activities and clash anchors are reported in the Persian Gulf annually. In this paper, response of pipeline against the traction of hooking the anchor and trawling the gear is studied. In other words, the strength of a pipeline against a lateral load will be evaluated. The actual situation of a gas pipeline lying on the seabed of the Persian Gulf is modeled regarding soil, reinforced concrete and non-linear parameters.

As deepwater wells are drilled to greater depths, pipeline engineers and designers are confronted with new problems such as water depth, weather conditions, ocean currents, equipment reliability, and well accessibility. Subsea Pipeline Design, Analysis and Installation is based on the authors' 30 years of experience in offshore. The authors provide rigorous coverage of the entire spectrum of subjects in the discipline, from pipe installation and routing selection and planning to design, construction, and installation of pipelines in some of the harshest underwater environments around the world.

Hyams, M. This paper outlines the environmental management controls successfully implemented during the construction of two offshore mini-platforms and associated pipelines located in environmentally sensitive shallow tropical marine waters in the North West Shelf area of Western Australia. The innovative barge anchoring methods implemented during the installation of the pipelines were successful in ensuring that no significant damage occurred to the 1, coral bomboras surveyed within both pipeline alignments. These projects serve as a case study demonstrating that the installation ofpetroleum facilities can be successfully undertaken in sensitive marine environments with no adverse environmental impacts on sensitive seabed habitats. The Victoria and Double Island oil field developments involved the construction and stabilisation of two offshore pipeline bundles and the installation of two small offshore oil platforms. The Victoria development consists of an offshore mini-platform with capacity for six production wells.

Marine pipelines' most serious risks to human life and the environment have to do, not with corrosion, but with larger scale damage from anchors, fishing nets, and storm-induced failure of the supporting sediments see Chapter 2. In shallow waters less than about 15 feet , collisions of vessels with inadequately buried pipelines can kill as shown by the Northumberland and Sea Chief cases, in which fishing vessels burned and crew members died after the vessels struck exposed pipelines in shallow water. In deeper waters, anchor and net damage has been responsible for more than 90 percent of the pipeline oil pollution recorded on the OCS between and ; the four largest spills—all caused by anchor damage, and totaling , barrels—accounted for 85 percent of the volume of pollution from pipelines during this period see Chapter 2.
