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.

Founded in 2020, the company is young — but our team brings decades of combined offshore survey and submarine-cable experience to every mobilization. From a single-day site visit to a full turnkey cable campaign, we scope the work around your objectives, standards and schedule.

Mission

At CS Marineland we solve the most demanding technical challenges in hydrography, marine geophysics and subsea infrastructure — telecommunications and oil & gas — with international standards and tailor-made solutions. We do not aim to be the largest, but the best in specialized, high-value niches: getting to know each client and their operation in depth to develop the solution they truly need, acting as a technical and cultural bridge between global operators from Europe, Asia and North America and the realities of Latin America.

Vision

To be Latin America's benchmark firm in the specialized, high-value niches of hydrography, marine geophysics and subsea infrastructure — telecommunications and oil & gas — recognised not for its size but for being the best: for the quality of its products, its tailor-made solutions, and for always staying at the forefront, bringing the world's most advanced solutions to the region.
