Abstract
Methods and apparatus for deploying pipeline from a vessel are described in relation to pipelines with installed accessories. One or more accessory support structures are installed at appropriate bedding locations on the seabed. In deploying pipeline from a vessel, an accessory is then attached at a position along the pipeline to correspond with the pre-installed accessory support structure bedding location. The pipeline and attached accessory are deployed and guided into engagement with the pre-installed accessory support structure on the seabed such that the pipeline is deployed substantially horizontally through the accessory support structure, and the accessory is supported by the pre-installed accessory support structure at the bedding location.
