We are particularly experienced in markte and riverine surveys which others may feel ore inaccessible, logistically too complex, or too small to be worth their while undertaking. Full onshore support is provided by a team of professionals and our dedicated processing and laboratory facilities ensure a rapid turnaround of results and reports. Coastline offers a wealth of scientific and industrial experience and expertise in-house and we pride ourselves in our strong liaison with experts nationally and worldwide.

Coastline is dedicated to providing the highest possible levels of safety and service. Efficient, effective and easy to do business with. Coastline Surveys Ltd offers solutions for all your survey needs.

Coastline Surveys Ltd regularly participates in marine surveys associated with port development, dredging, marine mining, construction and industrial monitoring compliance projects. Scientific research and policy development relating to coastal zone activities is also undertaken in association with national governmental organisations.

Coastline Surveys Ltd owns and continually invests in new technology and has lead the development of several novel data acquisition techniques tailored to specific Client needs.

Integration of data with management structures has led Coastline Surveys Ltd to develop graphic visualisation techniques in reporting to display multidisciplinary geoscience data in a format that non-specialist decision-makers can quickly assimilate.


High Power Vibrocorer

Coastline Surveys operate a high-powered electric twin-linear vibrocorer producing a centrifugal force of 9100Kgs from a 415v, 50-60Hz 3 phase power supply. This system has proven to achieve possibly the best penetration and recovery statistics of any high-powered Vibrocorer in the UK during 2009. This unit has a modular frame construction allowing for the recovery of 3 or 5 metre continuous 86 mm diameter samples in water depths of up to 200 metres. ...

Dual Frequency Side Scan Sonar

The GeoAcoustics Dual Frequency Side Scan Sonar system is the ideal tool for seabed feature mapping, offering flexibility and high quality results in a simple and reliable package. The system offers high resolution, switch selectable, dual frequency operation (100/410 kHz), which when combined with multiplexed data transmission enables a low drag coaxial tow cable to be used. This also facilitates simple installation onto remotely operated vehicles ...


Environmental Monitoring

Environmental monitoring and impact assessments are becoming ever more important in regulations governing activities in the marine environment and in firms' applications for BS7750 accreditation. The Harbour Works (Assessment of Environmental Effects) Regulations of 1988 & 1992 and the Environmental Protection Act of 1990 require planners and engineers, involved in harbour and marina developments, to carry out detailed site investigations to ...

Route Surveys for Cables, Pipelines & Outfalls

Prospective routes for river crossings, sea outfalls, cables and pipelines must be identified, studied and selected prior to construction. Monitoring of the progress should be continued during the operation and afterward to ensure its continued safe operation. Gathering such data at an early stage allows designs to accommodate seabed conditions, thus saving otherwise costly delays later in the project due to unforeseen ground conditions. Using a ...
