Abstract
A method of laying a pipeline comprising a plurality of tubular components is disclosed. The method includes depositing a weld material onto a surface of a first tubular component of the plurality of tubular components and machining a profile into the weld material. The profile includes a support shoulder into the weld material. The method further includes suspending the first tubular component in a vertical or near vertical position and supporting the first tubular component by the support shoulder. A further tubular component of the plurality of tubular components is connected to a free end of the first tubular component. The support shoulder is formed at a point spaced from the free end of the first tubular component thereby facilitating connection of the first tubular component to the second tubular component.
