Submarine pipelines are externally concrete coated to ensure vertical and lateral stability on seabed without excessive movement. During operation and especially towards late life and beyond, concrete may be lost which must be compensated in the form of stabilization weights. The weight requirements are typically calculated based on concrete...

Subsea pipelines, such as in-field flowlines, trunklines, etc., are an integral part of all offshore field developments. Pipeline damage can occur either during construction phase or during the life of field. Critical pipeline damage such as leak, rupture, or crack requires repair to be performed on an emergency basis. Repair readiness is being...

Subsea pipelines originating from offshore fields and approaching land are required to be buried in near shore area to provide protection against environmental loading, marine activity, instability and unfavourable soil conditions. This paper presents an innovative approach to optimize near shore burial requirements of subsea pipelines. This...

Subsea pipelines are externally concrete coated to provide vertical and lateral stability. The loss of concrete can lead to floatation or lateral movement on the seabed. If seabed is hard/rocky, then lateral rubbing may lead to wall thinning at 6 o'clock and can result in a leak or flattening at the bottom affecting ovality. This paper presents...

Subsea pipelines such as flowlines, trunklines etc. are an integral part of all offshore field developments. Sour service conditions as encountered by production pipelines of gas fields require CRA clad pipe due to high risk of localized corrosion initiation and penetration rate in carbon steel. This paper presents an innovative approach to...
