摘要： An apparatus (1) for restricting the bending of a tubular member underwater comprises a plurality of interlocking modules each formed from a first half shell component (2) circumferentially displaced from a second half-shell component (3), wherein the first half shell component comprises one or more projections (19) extending from a side edge (18) thereof and the second half shell component comprises one or more grooves (21) in a side edge (18) thereof, the projections and grooves being angled to the side edges of the first and second half shell components, the arrangement being such that when assembled together each of the one of more projections of the first half shell component are inter-engaged with a corresponding groove of the second half shell component to secure the two half shells together.
