Polyspace™ is used to provide clearance between new cables or pipelines and existing cables or pipelines on the seabed. The system consists of free flooding moldings, supplied with ballast to provide additional submerged weight if needed.
PolyspaceTM uses clamps to secure the moldings to the host line during the over boarding or installation phase. No further post-lay operation is necessary to obtain the required separation.
Each PolyspaceTM solution can be tailored to the specific environmental conditions at the installation location. The lead ballast can be varied to give up to 100 kg/m submerged weight. The number of clamps can be varied to secure the PolyspaceTM string to the host line.
PolyspaceTM moldings are hollow and lightweight for ease of installation. The moldings are free-flooding eliminating any pressure differential effects at various water depths.
The PolyspaceTM system includes polyurethane stiffeners at each end of the string to protect the host line as it exits the main moldings.
