Miko Marine Will Provide Magnetic Hull Closures for Modec’s FPSO That Will Operate in the Bacalhau Offshore Field Located in the Pre-salt of the Santos Basin

The Norwegian company Miko Marine will deliver four cofferdams and water ingress seals for a Modec FPSO being constructed at a shipyard in China that will operate in Equinor’s Bacalhau field in the Brazilian pre-salt of the Santos Basin. According to the company, the new sea chest inlet covers are scheduled for delivery in March 2021.

These equipments feature Miko’s magnetic accessories and will be available for installation and repeated use without the need for welding or permanent fixtures on the hull.

“They provide the benefit of allowing repairs and maintenance to be carried out within sea chests whenever necessary and without the need for dry docking, thus allowing the FPSO to remain on station,” said Miko Marine.

The Modec FPSO project in the Bacalhau field will use high-power permanent magnets to position and hold the cover in place. Depending on the size of the cover, four to ten powerful Miko MAM permanent magnets are used to keep the cofferdam in place.

“With each magnet capable of supporting up to 2,000 kg, it is possible to achieve an immediate watertight seal for the closures, without the need for any other fastening device being installed on the hull. The buoyancy material is integrated into the sealing plates, making them neutrally buoyant and easy to handle underwater by ROVs “, explained Miko Marine.

Additionally, Miko stated that each magnet is attached to its closure by a flexible joint that allows the plate to be maneuvered and positioned precisely against the hull of Modec’s FPSO before being tightened in place.

“When the repair work is completed, the magnets are simply released with their release lever turned by a diver or ROV, allowing the raw piece to be quickly retrieved by a crane and stored on board”, said the Norwegian company.

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.

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.

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 seemingly endless sand is disappearing: the world extracts 50 billion tons per year from rivers and beaches, a volume comparable to 19,000 pyramids of Giza, while mafias profit, islands disappear, and city concrete is threatened until 2050.

Scientists drill 8,000 feet of ice in Antarctica and race against time before the hole freezes over again to bury the world’s deepest seismometers and turn the South Pole into a giant ear for earthquakes across the entire planet.

Rice in space becomes a scientific bet for China to understand how microgravity can alter the genetics of the most important grain for Asian food security and reveal if future generations of the plant can be born, grow, and maintain their biological identity away from Earth.

How much would a Toyota Hilux cost without tax in Brazil? A diesel pickup truck priced at R$ 250,000 could drop to around R$ 127,000, showing why pickup trucks have become a luxury product in the country.

Windows without a prison-like appearance gain momentum in 2026 and promise to completely transform residential facades with more natural lighting, discreet security, increased property value, and a modern look without the burden of the old iron bars that dominated Brazilian homes for decades.
