摘要：
A positioning member (11) for a tubular (10) is formed using a prefabricated fiber-reinforced resin shell (1) positioned upon a surface of the tubular and bonded to provide a protrusion upon the surface of the tubular. In a disclosed method a fiber-reinforced resin shell (1) is secured to an external surface of a tubular (10) thereby enclosing a cavity between the shell (1) and the surface of the tubular (10); a bonding agent is introduced through inlet ports (5) in a surface of the fiber-reinforced resin shell (1) to fill a cavity between the shell (1) and the surface of the tubular (10), and the bonding agent is cured.
