Engineering Projects,
Planning, Removal and Disposal

In 2022, Ocyan secured a contract in the subsea decommissioning sector to remove flexible pipelines and umbilicals from the seabed. The work was carried out in the Campos Basin (FPSO Cidade do Rio de Janeiro and FPSO Cidade de Rio das Ostras) and the Sergipe-Alagoas Basin (FPSO Piranema). The project involved engineering activities, offshore retrieval operations, transfer to a yard, cleaning, conditioning, and final disposal.

The removed pipelines were located at depths ranging from 800 to 1,700 meters, spanned a total length of 275 km, and weighed nearly 20,000 tons. The project was executed using the Norwegian vessel *Normand Cutter*, chartered from the company Solstad Offshore.

EPCI offshore

In 2023, Ocyan winned a contract to carry out the revitalization of the gas network in the Campos Basin. We will provide services in offshore EPCI projects, which include engineering, procurement, construction, and installation of equipment. We are partnering with the Portuguese company Mota Engil, which has a strong international presence, especially in Europe and Africa. The offshore activities will take place near the Namorado and Garoupa platforms (PNA-1 and PGP-1), and include the installation of various subsea equipment, including manifolds, and flexible pipe installation. The first stage of the project, involving the engineering phase, is expected to commence immediately, and offshore operations are anticipated to begin in 2025. The execution of the Campos Basin network revitalization project involves hiring professionals, specialists, and technicians from various fields.

Our experience

Chartering and operation of flexible riser deployment units, SURF (Subsea Umbilicals, Risers, and Flowlines) projects, and export lines, as well as manufacturing and installation of subsea equipment.

Ocyan was the first Brazilian company to operate in the Subsea sector in the country and the first to use the MPD (Managed Pressure Drilling) technique. The company is committed to continuous innovation, providing sustainable, safe, and financially attractive solutions.

PIPE LAYING SUPPORT VESSEL (PLSV)

Ocyan operated, from 2014 to 2019, in partnership with the French company TechnipFMC, through the TOP Joint Venture, in the operation of the TOP Estrela do Mar and TOP Coral do Atlântico units along the Brazilian coast. These flexible pipe-laying vessels (PLSVs) were the only units in Petrobras' subsea interconnection fleet to successfully install production lines with a silicone layer.
