Abstract

In a system comprising a rigid or flexible pipe provided with at least one float, intended for a floating pipeline, each float being composed of a foamed plastic pre-fabricated core enveloping a specific length of the pipe and a protective outer sleeve of glass fibre-rein forced resin, the core is constructed from a series of separate parts at least two of which have the shape of a ring segment, such signals together forming a ring surrounding the pipe with a small clearance and advantageously being held together by the glass fibre-reinforced unsatd. polyester resin outer sleeve. Plastic may be PVC, polyurethane etc. Whilst not bonded to the pipe surface the floats are held so that they do not slide along the pipe and the foam core is protected against damage by the external, preferably laminated, envelope or sleeve. Used for providing the buoyancy for a floating pipe running from e.g. a sand dredger to the shore.
