Hydrographic & Marine Surveys · Submarine Cable

From the seabed
to the shore end.

CS Marineland delivers high-precision marine geophysical surveys and turnkey submarine cable installation — engineered for oil & gas, telecom, environmental and archaeology projects.

Marine Geophysical Survey

Multibeam, side-scan, sub-bottom, magnetometry, marine seismic and geotechnical coring — acquired, QC'd and processed to survey-grade standards.

Submarine Cable

Route design, pre-lay shore ends, DSE, non-repeated cable installation and full turnkey (EPC) delivery — from desktop study to as-built.

Data & Engineering

Rigorous processing, charting, GIS and reporting in your datum of choice — turning the seafloor into clear, decision-ready deliverables.

What we acquire

Marine Survey Services

A complete geophysical and geotechnical toolkit for the seabed and sub-seabed — deployed from survey vessels of any size, anywhere in the region.

Multibeam Bathymetry (MBES)

Full-coverage, high-resolution seabed mapping with tightly controlled positioning and sound-velocity correction.

Sub-Bottom Profiler (SBP)

Imaging of shallow stratigraphy and sediment layers for burial assessment, geohazards and foundations.

Side Scan Sonar (SSS)

High-definition seabed imagery for targets, debris, boulders, cables and habitat characterisation.

Magnetometry

Detection of ferrous objects, UXO, pipelines and cables through precise magnetic-field gradient mapping.

Boomer & Sparker

Marine seismic sources for higher-energy sub-bottom penetration where deeper geology matters.

Marine Electrical Tomography

Marine ERT for sub-seabed resistivity imaging — sediment type, freshwater lenses and burial conditions.

2D High-Resolution Seismic

2D HR seismic reflection for detailed sub-surface structure in oil & gas and engineering studies.

ROV Inspection

Remotely operated vehicles for visual inspection, positioning support and light intervention tasks.

AUV Survey

Autonomous underwater vehicles for efficient, high-quality deep-water and long-line acquisition.

Geotechnical Coring

Piston, vibro and box corers for sediment sampling, geotechnical characterisation and environmental baselines.

Where we work

Markets We Serve

The same survey and installation expertise, tuned to the standards and deliverables each industry demands.

Oil & Gas

Site surveys, route & hazard studies, rig positioning and pre-engineering geophysics for offshore developments.

Submarine Cable & Telecom

Route design, shore ends and installation for fibre-optic and power interconnectors between coasts and islands.

Environmental & Licensing

Baseline studies, benthic & coral characterisation and geophysical support for environmental permitting.

Submarine Archaeology

Detection, mapping and documentation of wrecks and heritage using SSS, magnetometry and sub-bottom data.

End to end

Submarine Cable Services

From the first desktop study to the buried shore end — CS Marineland delivers the full cable lifecycle, including turnkey scopes.

Route Design & Desktop Study

Desktop studies, route engineering and burial assessment optimised for cost, risk and permitting.

Pre-Lay Shore End (PLSE)

Precision installation and floating of the shore end ahead of the main lay campaign.

Direct Shore End (DSE)

Beach pull-in with cable grabs and shore plant, burial and BMH tie-in — our field signature.

Non-Repeated Installation

Turn-key laying of non-repeated fibre and power cables between coasts, islands and platforms.

Turnkey (EPC) Projects

Single-point delivery: permits, survey, engineering, installation, protection and as-built.

Marine Site Visits

Coastal and marine reconnaissance, CSR support and constructability reviews before mobilisation.

Credibility you can audit

Certifications & Compliance

CS Marineland runs every project under an integrated HSEQ management system — independently certified and formally licensed for marine and oil & gas operations.

Quality Management
Environmental
Health & Safety

Independently certified by Bureau Veritas — ONAC-accredited (ISO/IEC 17021-1).

DIMAR — Marine Operating LicenseLicencia de Explotación Comercial No. 401542 — authorised for marine research and subsea infrastructure works in Colombian waters (valid to 2029).
RUC® — Oil & Gas HSEEvaluated under RUC® (Consejo Colombiano de Seguridad) — the contractor HSE standard required by Colombia's hydrocarbons-sector operators.
ICPC MemberMember of the International Cable Protection Committee — aligned with global standards for the safe survey, installation and protection of submarine cables.

Every project runs to a project-specific HSEQ plan, under our integrated ISO 9001 / 14001 / 45001 management system — so quality, safety and environmental compliance are built in from mobilisation to as-built.

Who we are

Field-proven operations,
survey-grade data.

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.
