    WEALTH FROM OCEANS www.csiro.au Subsea Pipelines Collaboration Cluster Advancing our knowledge of subsea pipeline technology to support the oil and gas industry Final report 2 Executive summary 17 Putting the Cluster’s research into practice 4 Introduction to the Subsea Pipelines Cluster 21 Commissioning experimental equipment 6 Training the offshore for ongoing pipeline pipeline engineers testing in Australia of the future 28 Publications and 10 Scientific and dissemination engineering challenges 34 Key papers 12 Scientific outcomes of the Flagship 46 Awards Collaborative Cluster 48 Keynote presentations, invited lectures and papers 49 Hosting international conference ISFOG 50 The Partners 51 Flagship Collaboration fund 1 Executive summary Offshore subsea pipelines are used to export oil and gas from the field to platform and then from the platform to the mainland. As they are the sole conduit for the hydrocarbons their stability and integrity are of critical economic and environmental importance. More than 80 per cent of Australia’s gas resources exist in deep, remote, offshore areas and being able to realise the full potential of these remote resources relies on the development of economically viable transportation solutions. Technical solutions for Australia’s offshore pipelines must maintain structural integrity and continuous supply of products across hundreds of kilometres of seabed. Such technology is also vital to Australia achieving the vision of “platform free fields”, a CSIRO Wealth from Oceans Flagship initiative. Platform free fields research investigates ways to replace traditional oil and gas platforms with subsea technologies for production of gas resources which may lie as far as 300 km offshore, at a depth greater than 1 km.

  • Method of Determining
    Hydrotransport 19 Conference, Sept 24-26, 2014, Denver, USA Options for fixed mechanical sand bypassing at river entrances N.T. Cowper1, L. Nankervis2 and A.D. Thomas3 Slurry Systems Pty Limited, Sydney, Australia 1, [email protected] 2, [email protected] 3 [email protected] ABSTRACT Littoral drift of sand along coastlines can result in sand bars forming off ocean entrances causing navigational problems. Conventional management of these sand bars involves regular dredging. Two alternative fixed sand bypassing technologies are considered. The world’s first large scale fixed bypass system at Nerang, Queensland, Australia, is described. Since 1986 it has bypassed around 17 million m3 of sand. The system consists of 10 jet pumps mounted along an offshore jetty. An alternative option, not requiring a jetty, is to use a Submarine Sand Shifter (SSS) buried beneath the sand. The development, pilot plant testing, and operational experience of the Sand Shifter is described. 1. INTRODUCTION Littoral drift is a natural process due to sand being suspended by the energy dissipated in breaking waves. The resulting sand movement is predominantly towards the beach shore. However, when waves strike the beach at an oblique angle there is a shore parallel component of sand movement, or littoral drift. The quantity of littoral drift sand varies depending on wave climate. Depending on the prevailing wave direction, sand bars may build up across river entrances, inhibiting navigation. The conventional solution involves regular dredging of the entrance. A fixed sand bypassing system can provide a more economical alternative. Fixed sand bypassing involves a system to intercept the littoral drift sand before it reaches the entrance and pump it ashore to an on-shore pump station.

  • Hydrodynamic Forces on Subsea Pipes Due to Orbital Wave Effects
    Hydrodynamic Forces on Subsea Pipes due to Orbital Wave Effects Lisa King Jeremy Leggoe1, Liang Cheng2 1School of Mechanical and Chemical Engineering 2School of Civil and Resource Engineering CEED Client: Woodside Energy Ltd Abstract Pipeline stability design relies on an accurate prediction of the hydrodynamic forces induced by wave and current motion. The motion of wind generated waves is generally orbital, and the orbit paths flatten to an ellipsoid with depth. This leads to the assumption in deepwater that the vertical components of the wave motion tend to zero near the seabed. Due to this simplification wave motion is often modelled as rectilinear for the purposes of analysing on-bottom pipeline stability. This simplification predicts that the magnitudes of the hydrodynamic forces are equal on the forward and reverse half wave cycle. In computational fluid dynamics (CFD) modelling results have shown the drag force exerted on an on-bottom pipeline was 7% higher than expected on the forward half wave cycle, and 5% lower on the reverse half-wave cycle when waves were modelled as orbital rather than rectilinear. This paper describes CFD modelling to be conducted to investigate this phenomenon and verify the validity of this result. 1. Introduction Pipeline stability is an integral part of the offshore oil and gas industry and in particular is a major challenge for pipeline operators in the Australian North West Shelf (NWS). Due to the severity of the environmental conditions in the NWS, pipeline stabilisation can be a significant project cost, contributing up to 30% of the capital expenditure (Zeitoun et al.

  • Shedding Damage Detection of Metal Underwater Pipeline External Anticorrosive Coating by Ultrasonic Imaging Based on HOG + SVM
    Journal of Marine Science and Engineering Article Shedding Damage Detection of Metal Underwater Pipeline External Anticorrosive Coating by Ultrasonic Imaging Based on HOG + SVM Xiaobin Hong, Liuwei Huang , Shifeng Gong and Guoquan Xiao * School of Mechanical & Automotive Engineering, South China University of Technology, Guangzhou 510641, China; [email protected] (X.H.); [email protected] (L.H.); [email protected] (S.G.) * Correspondence: [email protected] Abstract: Underwater pipelines are the channels for oil transportation in the sea. In the course of pipeline operation, leakage accidents occur from time to time for natural and man-made reasons which result in economic losses and environmental pollution. To avoid economic losses and environ- mental pollution, damage detection of underwater pipelines must be carried out. In this paper, based on the histogram of oriented gradient (HOG) and support vector machine (SVM), a non-contact ultrasonic imaging method is proposed to detect the shedding damage of the metal underwater pipeline external anti-corrosion layer. Firstly, the principle of acoustic scattering characteristics for de- tecting the metal underwater pipelines is introduced. Following this, a HOG+SVM image-extracting algorithm is used to extract the pipeline area from the underwater ultrasonic image. According to the difference of mean gray value in the horizontal direction of the pipeline project area, the shedding Citation: Hong, X.; Huang, L.; Gong, damage parts are identified. Subsequently, taking the metal underwater pipelines with three layers S.; Xiao, G. Shedding Damage of polyethylene outer anti-corrosive coatings as the detection object, an Autonomous Surface Vehicle Detection of Metal Underwater (ASV) for underwater pipelines defect detection is developed to verify the detection effect of the Pipeline External Anticorrosive method.

  • Shipping Databases, the Case of Lloyd's Register of Shipping
    City, University London Shipping Databases, the case of Lloyd’s Register of Shipping Petar nikolov January 2020 Submitted in partial fulfillment of the requirements for the degree of MSc or MA in Library Science Supervisor Dr. David Bawden Abstract This project is aimed at the Library and Information Science field, with the purpose of discussing industrial databases, more specifically shipping and shipbuilding databases. This project is focused mainly on the Lloyd’s Register of Shipping. We will start by discussing the historical basis which enabled the establishment of such a database, why it was created and what purpose it had in the field of shipping and what was the role it played in the shipbuilding industry. In this part we will look at the developments of the shipping from the medieval time to the time when the Lloyd’s Register was created by the London underwriters during 1760. From there we will pick up by looking at the early history of the register and why at the end of the eighteenth century a rival register was created by the shipowners. We also look how the two registers slowly began to decline and how finally they reformed themselves into the current register in the year of 1834. The next part of the project will be concerned with the nineteenth century shipbuilding developments and how the Lloyd’s Register responded to them. We will look at the transition from wood to iron and then from iron to steel. In both cases the Lloyd’s Register of Shipping developed sets of rules to govern how ships of iron and steel should be built, alongside the rules it has established for building of wooden vessels.

  • Stability of Offshore Pipelines in Close Proximity to the Seabed
    6th Pipeline Technology Conference 2011 Stability of Offshore Pipelines in Close Proximity to the Seabed F. Van den Abeele and J. Vande Voorde ArcelorMittal Global R&D Gent (OCAS N.V.) J.F. Kennedylaan 3, BE-9060 Zelzate, Belgium ABSTRACT In traditional offshore pipeline design, the on-bottom stability of submarine pipelines is governed by the Morrison’s equations. According to this set of equations, offshore pipelines are designed to satisfy two stability conditions: the submerged weight of the pipe has to be greater than the lift force, and the horizontal frictional force should exceed the combined drag and inertia forces. It is common practice to used fixed hydrodynamic coefficients (drag, lift and inertia) to calculate the pipe stability, based on the assumption that the pipeline is either trenched or in contact with the seabed. However, due to uneven seabed topology and/or scouring, a gap may exist between the pipe and the seafloor. In such a case, the force coefficients not only depend on the relative gap between the pipe and the seabed. Moreover, in unsteady oscillatory flow (induced by waves), the time- dependent laminar or turbulent characteristics of the boundary layer become important. In this paper, a computational fluid dynamics (CFD) model is presented to study on- bottom stability of offshore pipelines in close proximity to the seabed. Numerical simulations of fluid flow are performed to evaluate the lift, drag and inertia forces exerted on a subsea pipeline when subjected to both steady current (tides) and oscillatory flow (waves). The evolution of the hydrodynamic coefficients with the relative gap between the pipe and the seafloor is investigated, and the effect of boundary proximity on the stability is revealed.

In this article, the hydrodynamic forces on the submarine pipeline and the characteristics of tidal flows around the pipeline are studied depending on a high-fidelity multi-physics modeling system (SIFOM–FVCOM), which is an integration of the Solver for Incompressible Flow on the Overset Meshes (SIFOM) and the Finite Volume Coastal Ocean Model (FVCOM). The interactions between coastal ocean flows and the submarine pipeline are numerically simulated in a channel flume, the results of which show that the hydrodynamic forces on the pipeline increase with the increase of tidal amplitude and the decrease of water depth. Additionally, when scour happens under the pipeline, the numerical simulation of the suspended pipeline is also carried out, showing that the maximum horizontal hydrodynamic forces on the pipeline reduce and the vertical hydrodynamic forces grow with the increase of the scour depth.
