With Offshore Works Expected to Start This Year, Subsea7 Secures Contract with Giant Shell in the Campos Basin

Subsea 7 secured what it claims is a “significant” contract from Shell for the decommissioning of underwater infrastructure off the coast of Brazil, according to offshoreenergy and subsea7.com. The contract calls for Subsea 7 to carry out the decommissioning of the underwater infrastructure associated with the FPSO Fluminense in the Bijupirá and Salema fields, at a water depth of 700 meters.

The Contract and the Works to Be Carried Out

The company’s scope includes disconnection, recovery, and disposal of ten flexible risers, three umbilicals, and nine mooring cables. Offshore works are expected to start later this year, in December.

Yann Cottart, vice president of Subsea7 Brazil, said: “Twenty years ago, Subsea7 installed the flexible risers and umbilicals for Shell’s Bijupirá and Salema fields, and two decades later, we are proud to be one of the contractors chosen by Shell to participate in the completion of this field’s life cycle.”

About the FPSO and the Decommissioning Contract

The FPSO Fluminense, 390 meters long and with an LDT of 51,000 Mt, was commissioned in 2003 in the Bijupirá and Salema oil fields. These fields are located adjacent to each other, about 250 kilometers east of Rio de Janeiro, in water depths ranging from approximately 470 to 800 meters.

Shell formalized a limited notice to proceed (LNTP) with Modern American Recycling Services, Europe (MARS) earlier this year for the dismantling and green recycling of the FPSO Fluminense.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

The coastal El Niño is not the classic El Niño, but it already raises a question in Brazil: can the phenomenon alter rain, heat, and winter?

The commander of the Brazilian Army publicly admitted that the country now perceives real threats in South America, something that, according to him, did not exist in the past, and advocates for the increasing use of drones and technology to secure the borders.

In China, even those who beg on the street already have a QR Code, paper money has practically disappeared from daily life in just ten years, and the entire country has come to live on invisible payments via mobile phones.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Scientists considered detonating 213 nuclear bombs in the Sahara to create an artificial sea the size of El Salvador, with each explosion being a hundred times more powerful than the Hiroshima bomb, and the goal was to generate more energy than Egypt’s largest hydroelectric plant.
