LANCASHIRE, UK – BP has awarded Trelleborg an order for foam buoyancy systems for the second-phase development of the Shah Deniz field offshore Azerbaijan. Trelleborg will supply a buoyancy package filled with its high-temperature syntactic foam.
Large cyclic changes can cause expansion of the flowline, resulting in lateral or upheaval buckling. And at a depth of 600 m (1,968 ft) below surface, these flowlines will come under significant force. Trelleborg buoyancy modules will assist in mitigating this. By reducing the self-weight of the flowline and friction against the seabed, a span of lower resistance is established along the flowline, enabling the buckling to occur in known and controlled conditions.
