Not All Underwater Reefs are Made of Coral
to learn which types of artificial reefs are best suited for enhancing habitat for particular sorts of fish.For example, we know that large predators that dwell in open water, such as jacks, barracuda and sharks, tend to prefer taller artificial reefs over shorter ones. This is similar to insights from oil rigs, showing that these vertical and complex structures are valuable fish habitat. More than 500 decommissioned oil rigs have been converted to reefs. Our calculation included only those that are managed by state artificial reef programs.Other structures in the water, such as offshore wind turbine foundation

trajectory emphasizes systems without membranes for heightened efficiency.”One of the key advantages of this innovation is its versatility and scalability. The system can easily be integrated into existing onshore infrastructure, such as desalination plants, as well as offshore locations like oil rigs.“While eDOC won’t single-handedly turn the tide on climate change, it enriches our mitigation toolkit,” added Rahimi. “In this global challenge, every innovative approach becomes invaluable.&rdquo
Halliburton, Baker Hughes Beat Profit Estimates as International Demand Offsets Weak N. America
for oilfield services internationally, even as domestic activity stumbled. While oilfield drilling has seen a resurgence abroad, particularly in regions like the Middle East and Latin America, since Russia's invasion of Ukraine, weaker oil and gas prices have forced U.S. shale producers to cut oil rigs. "Growing economic uncertainty continues to drive commodity price volatility globally... Market softness in North America is expected to be more than offset by strength in international and offshore markets," Baker Hughes chief executive officer Lorenzo Simonelli said in a statement

Baker Hughes Finds US Drillers Add Most O&G Rigs Since April
oil prices prompt more drillers to return to the wellpad.The oil and gas rig count, an early indicator of future output, rose 13 to 601 in the week to Jan. 14, its highest since April 2020, said Baker Hughes in its weekly report. The total count was up 228, or 61%, over this time last year.U.S. oil rigs rose 11 to 492 this week, their highest since April 2020, while gas rigs rose two to 109, their highest since March 2020. Specifically, the Eagle Ford in South Texas gained six rigs this week, the most of any basin, bringing its total to 50, its highest since April 2020. The Haynesville shale in

In the ice floes, the scientists predominantly found similar paint particles and nylon waste from fishing nets.The question that remains is how these omnipresent particles impact living organisms.eXXpedition founder Emily Penn studying a sample. © Eleanor Church Lark Rise Pictures“Survival

But it’s also where the human racket from fishing boats, tankers and motorboats, as well as oil rigs and wind turbines, gets trapped and then propagated around the world.Sound waves travel farther and faster in water than in the air. That’s especially true of the bass notes of a whale’s song, the low grinding of a ship’s shaft, even the rumble of a nuclear explosion. Those sounds

, the Fugro Synergy. Now, they are working together again in order to better prepare for the future.The Fugro Synergy vessel has been in operation since 2009, and is primarily used to drill into the seabed in order to analyse whether it can be safely used as a foundation for structures like wind farms or oil rigs. This ship was built to be effective in the harshest conditions, and Bosch Rexroth provides the drives and controls for operating under these circumstances.During the operation, motion compensation of the vessel at sea is one of the drive and control challenges we faced.

Offshore workers, routinely transported to oil rigs and other offshore installations by helicopter, need to know what to do when their helicopter ditches into the sea and RelyOn Nutec, in association with Survival Systems Limited, has just the right facilities, equipment and personnel to show them what has to be done to ensure survival.
