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.

Abstract: A method of forming a collar on a tubular component is described. The method includes the steps of depositing a weld metal onto the surface of the tubular component, machining the collar into the weld material, and machining a support shoulder into the collar to facilitate suspension of the tubular component.

Abstract: A method of machining the internal bore of a hollow pipe comprises honing material from inner surface of the bore the pipe. A honing apparatus for use in the method comprises a machining tool comprising a honing head adapted for insertion into the end of a pipe to remove material from the inner surface of the pipe by abrasion.

Abstract: A method of increasing the surface roughness of a coated pipe comprises the steps of applying a particulate material to the outer surface of the pipe including the field joint coating at the ends of the pipe.
