Before a vessel is booked, it gathers what is already known about the site and turns it into a plan for the field work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What it usually covers<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Existing surveys:<\/strong> earlier bathymetry, geophysics and borehole logs from the area, including data from neighbouring projects where it can be used.<\/li>\n\n<li><strong>Geology:<\/strong> published maps and papers that describe the expected layers, such as soft clays, sands, gravels or rock at shallow depth.<\/li>\n\n<li><strong>Hazards:<\/strong> known wrecks, cables, pipelines, unexploded ordnance risk, boulder fields and areas of mobile sand.<\/li>\n\n<li><strong>Conditions:<\/strong> water depths, tides, currents, waves and the season when work at sea is most likely.<\/li>\n\n<li><strong>Constraints:<\/strong> permits, protected areas, shipping lanes and fishing activity.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The result is a first ground model with its gaps marked, and a proposed survey that targets those gaps. It is also the moment to agree which questions the investigation has to answer for the designers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bring the survey team in while the layout can still move.
