Paper 43 - Deep Water Pipeline CT 9_2_15John Grover
This document discusses the use of coiled tubing as down-lines for pre-commissioning deepwater pipelines. It compares coiled tubing to other down-line options like flexible lines. Coiled tubing has advantages over flexible lines in terms of cost, delivery time, deck space requirements, reliability, and ability to provide contingency. The document outlines the latest custom coiled tubing equipment being deployed, which is designed for large diameters of 2 7/8" or 3 1/2" pipe and to operate in water depths up to 3,000m. It was also designed to be road transportable and for flexible installation on vessels through a moonpool or over the side.
This document proposes an alternative design for constructing the foundations of a new pedestrian bridge across a harbour.

This document provides the design calculations and requirements for upgrading the cathodic protection system for an existing gas pipeline and three new LPG product pipelines in Vietnam. An impressed current cathodic protection system using titanium anodes will be installed to supplement the pipeline coatings and provide corrosion control. Soil resistivity measurements along the pipeline route indicate aggressive soil that justifies an effective groundbed for cathodic protection. The design calls for a 30-year life, 30 mA/m2 current density, 95% coating efficiency, and 850mV negative potential criteria. Calculations determine the necessary cathodic protection current, number of anodes, and estimated groundbed resistance at two station locations along the pipelines.
Shortcreting has proved to be the best method for construction of curved surfaces. Domes are now much easier to construct with the advent of shotcrete technology. Tunnel linings are also becoming easy with this technology. Not only are these but there a wide range of applications where this technology has been a leading one. This technical paper includes the concept of shotcrete and how it differs from conventional concrete. It also enumerates the different types of process involved in shotcreting i.e. dry mix process and wet mix process. Advantages of shotcrete and its applications in various fields like tunneling, canals, buildings etc. are specified in detail. This paper presents an overview of shotcreting technology along with its applications.
DEFINITION OF SHOTCRETE:-
Shotcrete is a mortar or high performance concrete conveyed through a hose and pneumatically projected at high velocity onto a backing surface. It is the force of this spraying action that leads to compaction of the concrete or mortar which then forms layers of concrete to the required thickness. Shotcreting has been an acceptable way of placing cementitious material in a variety of applications.
Usually patented polypropylene fibers are included in the shotcrete which increases the cohesive nature of the shotcrete through mechanically binding the cementitious materials together. This mechanism reduces the rebound waste that occurs through the shotcreting process and these fibers also resist plastic shrinkage and cracking through their ability to enhance the early stage tensile strength of concrete.
Shotcrete also gives better surface finishes and reduces surface tearing on non- linear sections. Cementitious material containing the poly propylene fibers resist cycles of freezing and thawing and also reduces the chances of water and chemical penetrations.

6. Due to the different pressure underground, the water always flow from the high pressure area to low
pressure area where drain hose been buried. The underground water, surrounding the drain hose, will be
attracted by its weft yarn (capillary attraction) and collected in the hose, then drained out. This
continuous movement will lower the level of underground water effectively without any soil collapse and
chemical contamination. 利用土壓的原理而產生壓力差,而軟式透水管用鋼線做支撐體故使孔隙
水進到管內,管壁的緯紗有了毛細現象,吸水飽和流入管內後形成一條水道,因而達到了降
低地下水位的功能,且不會造成土層崩蝕及造成化學污染。
Drain hose is able to lower the level of underground water、drain the surface and penetrating water out
to improve the soil、solidify the soft soil and avoid soil collapse. 廣水軟式透水管可降低地下水位、

需用接頭,節省接頭費用。
(We fabricate bends, tees, elbows reducer by using the parent hose.)
使用同軟管連接
The hose can be installed horizontally, vertically, diagonally or in
herringbone design or 90
。
or any other way the client wishes to
install.
軟管安裝方法可橫向,直向,斜向,八字型,可90。

Static Pressure of Ground
The static pressure of ground above the buried
pipe can be counted pre following formula:
P: Static pressure of ground (kg/m2)
h: the burying depth
B: the width of ditch
W: the weight of 1 m3 soil (2000kg/m3,soil and
rock)
Ө: 40゚ (the angle of ____ ) (May adjust)
e: the base of _____ (May adjust)

NOTE:THE BACKFILLING MATERIALS WILL DEPENDS ON.
1.COST BETWEEN AGGREGATE AND SAND.
2.THE RATE OF INFILTRATION, USING AGGREGATE WILL CREATE A BETTER POROUSITY AND WILL
ENHANCE THE PERMEABILITY RATES.
** 回填土溝之材料選擇,將隨著下列因素變更
1.骨材與粗砂的成本。
2.用粗砂會獲得較好的孔隙率,且會增進其滲透率及排水量。
