SEA s.r.l. is an Italian company highly specialised in sea trenching works. SEA differs from other companies in the same field because it can offer a complete service, including the design and building of its machinery (supervising the engineering part) and execution of trenching works. SEA’s main characteristic is the extreme versatility of its machines, which are suitable to perform trenches in most types of sea beds and with pipelines of various diameters. SEA s.r.l. was founded in 1992 and benefits from the experience of the technical director who has been developing trenching and dredging systems since 1970. A pioneer in Italy when it comes to studying, building and introducing the “post trenching system” to bury pipelines and cables. His methods have been so innovative and functional that all the post trenching machines in Italy and in the world to the present day, follow his technology. SEA has always been capable to solve all problems encountered during project executions, thanks to the company’s dynamicity, technical readiness and continuous development of its equipment.

This experience, combined with a team of young technicians and engineers allows SEA to be a continuously evolving company, focused on the search of new systems and equipment. The headquarters of the company are in Ravenna, (offices, warehouse and workshop) but the subsidiaries lie in MALTA and BRAZIL. These bases play an important role in the management of the projects that SEA performs all over the world.

In Malta there is a workshop where the machinery, previously studied in Ravenna, is manufactured and maintained.

In Brazil , Rio de Janeiro, Sea has the availability of spacious offices and a suitable deposit area with dock, which is used to moor the company’s naval means. This area is suitably fenced and controlled by security personnel.

In addition to burying operations, SEA technicians are available to examine a variety of solutions for the problems faced during the underwater operations in seas, lakes, lagoons, swamps or other water related sites.

SEA s.r.l.‘s main activities are the following:

  • Burial of sea lines (from 3” to 50”);
  • Shore approaches using Post trenching and Pre trenching systems, even in very resistant sea beds (lime rock, coral and cemented sand) without the use of cofferdam thanks to the new patented technology of RACK;
  • Laying and burial of electrical and power cables and optic-fibre cables;
  • Flogging of sea lines and cables;
  • River crossings;
  • The installation and assembly of small diameter pipelines;
  • Hydraulic control of sea lines;
  • Dredging of polluted materials deposited on the beds of ports, channels, rivers;
  • Sea line repairs;
