CS Marineland delivers high-precision marine geophysical surveys and turnkey submarine cable installation — engineered for oil & gas, telecom, environmental and archaeology projects.
Multibeam, side-scan, sub-bottom, magnetometry, marine seismic and geotechnical coring — acquired, QC'd and processed to survey-grade standards.
Route design, pre-lay shore ends, DSE, non-repeated cable installation and full turnkey (EPC) delivery — from desktop study to as-built.
Rigorous processing, charting, GIS and reporting in your datum of choice — turning the seafloor into clear, decision-ready deliverables.
A complete geophysical and geotechnical toolkit for the seabed and sub-seabed — deployed from survey vessels of any size, anywhere in the region.
Full-coverage, high-resolution seabed mapping with tightly controlled positioning and sound-velocity correction.
Imaging of shallow stratigraphy and sediment layers for burial assessment, geohazards and foundations.
High-definition seabed imagery for targets, debris, boulders, cables and habitat characterisation.
Detection of ferrous objects, UXO, pipelines and cables through precise magnetic-field gradient mapping.
Marine seismic sources for higher-energy sub-bottom penetration where deeper geology matters.
Marine ERT for sub-seabed resistivity imaging — sediment type, freshwater lenses and burial conditions.
2D HR seismic reflection for detailed sub-surface structure in oil & gas and engineering studies.
Remotely operated vehicles for visual inspection, positioning support and light intervention tasks.
Autonomous underwater vehicles for efficient, high-quality deep-water and long-line acquisition.
Piston, vibro and box corers for sediment sampling, geotechnical characterisation and environmental baselines.
The same survey and installation expertise, tuned to the standards and deliverables each industry demands.
Site surveys, route & hazard studies, rig positioning and pre-engineering geophysics for offshore developments.
Route design, shore ends and installation for fibre-optic and power interconnectors between coasts and islands.
Baseline studies, benthic & coral characterisation and geophysical support for environmental permitting.
Detection, mapping and documentation of wrecks and heritage using SSS, magnetometry and sub-bottom data.
CS Marineland delivers turnkey submarine cable projects — survey, route design, engineering, supervision, installation (lay, burial, shore end) and quality assurance — as principal contractor and single point of responsibility, combining our in-house capability with our network of specialised partner companies for each project.
Desktop studies, route engineering and burial assessment optimised for cost, risk and permitting.
Precision installation and floating of the shore end ahead of the main lay campaign.
Beach pull-in with cable grabs and shore plant, burial and BMH tie-in — our field signature.
Turn-key laying of non-repeated fibre and power cables between coasts, islands and platforms.
Single-point delivery: permits, survey, engineering, installation, protection and as-built.
Coastal and marine reconnaissance, CSR support and constructability reviews before mobilisation.
CS Marineland runs every project under an integrated HSEQ management system — independently certified and formally licensed for marine and oil & gas operations.
Independently certified by Bureau Veritas — ONAC-accredited (ISO/IEC 17021-1).
Certified scope (Bureau Veritas): Hydrography, marine geophysics, and consultancy in submarine cables.
Based in Cartagena, Colombia, Construcciones y Servicios Marineland S.A.S. (NIT 901.366.891-5) is a marine survey and submarine cable specialist working across the Caribbean and Latin America. We pair hands-on offshore experience with rigorous, ISO-certified processes — so every project ends in clear, decision-ready deliverables, in the datum and format you need.
From a single-day site visit to a full turnkey cable campaign, we scope the work around your objectives, standards and schedule.
