We provide Route survey services for pipelines/cables to assist the engineering party determine the optimum route and determine 'depth of burial' according to the seabed properties. Typically, a route survey is needed in the early stages of a pipeline installation project and is usually executed 6 months to 2 years before the actual pipeline installation.
Generally, in a Route Survey we attempt to establish some or all of the following:
- The topography and character of the seabed.
- The composition of the layer of sedimentary material immediately beneath the surface of the seabed.
- The presence of debris on the seabed.
- The confirmation of the positions of existing sub-surface structures, including pipelines, cables, templates and wellheads.
