Polar Onyx PLSV

June 27, 2014

NB Polar Onyx
The Polar Onyx is arguably the most modern PLSV working offshore Brazil. It is a good example of how Petrobras is demanding high-powered PLSV’s and OSV’s in general to tackle the harsh environments found in Brazil’s deepwater plays. The high capacity new-built is designed for operations in harsh conditions and deep waters and is configured with an Ulstein X-bow. It is built to the highest standard in dynamic positioning, DP3 (Operations +). Final outfitting took place in Schiedam in the Netherlands, where Huisman has installed a 275t vertical lay system (VLS) and a deck-mounted carousel with capacity for 2,000t of flexible pipes. Two permanent work-class ROVs delivered by Ceona’s partner ROVOP, which can operate in 3,000m water depth, were also mobilized in Schiedam.

Composites X Steel Deepwater Pipes

The development of pipes that can withstand high pressure, heat and corrosion in deepwater locations such as offshore Brazil and the GoM and WA is continuous. For many years steel piping dominated the O&G industry but with pre-salt projects beyond 2,000 meters deep and corrosive enhanced oil recovery techniques widely being used in the industry, pipeline manufacturers have been looking for more flexible and robust materials. France's Technip, which is a world leader in pipe manufacture, uses layered steel with a stainless steel or plastic lining for main offshore pipes. However, British engineering company Magma Global and Dutch company Airborne are pioneering composite pipes made from a fusion of high-end fibers and plastics which are up to 90% lighter than steel pipes and do not corrode.

Future Offshore Ocean Observatories - Part 1

Offshore Ocean Observatories, are composed of suites of surface and subsea instruments and sensors with long-term power supplies and permanent communications links that can feed data to scientific laboratories in real-time. Motivated by advances in computing, telecom, marine architecture and subsea sensor technology, researchers observe the oceans in real-time, for long periods of time, and sky around all the way to deepwater, including imaging and continuous sensor observation along the whole water column to the sea floor. Ocean observatories are designed to answer questions about how the seas and oceans work, their dynamics and peculiarities.

Brazil OSV Market

February 7, 2014

In the wake of the Subsea Vessel Brazil conference in Rio, Petrobras announced the approval to contract eight support vessels for its offshore activities. These are part of the 3rd Fleet OSV Renewal Plan (Prorefam). This is the 5th round and 4 vessels will be contracted from Bram Offshore, to be build at the Navship shipyard in the state of Santa Catarina, 3 from Starnav, with construction planned for the Detroit shipyard, also in Santa Catarina and 1 from Norskan, which will be built at the STX (Vard) shipyard in Niteroi, across the bridge from the city of Rio, where the Dof and Nordskan build all their Brazilian flagged ships. This is good news for the shipyards involved and for the OSV market in general, as the Brazilian offshore maritime market is heavily dependent on Petrobras orders.
