Underwater Vehicle Concept Inspired by Golf Balls
efficient and maneuverable, a new prototype developed at the University of Michigan has demonstrated.These nimble vehicles could access typically hard-to-reach areas in the ocean while conducting surveillance, mapping new areas or collecting data on water conditions.Golf ball dimples cut through pressure drag—the resistance force an object meets when moving through a fluid—propelling the ball 30% further than a smooth ball on average.“A dynamically programmable outer skin on an underwater vehicle could drastically reduce drag while eliminating the need for protruding appendages like fins
Sewage Contaminates British Waters
, the problems faced by the Holmyards underscore how failings with the most basic services in British society such as water and sewage can harm the broader economy.Reuters interviews with 20 people and data analysis show how polluted water has also hit tourism and delayed construction projects, acting as a drag on the economy at a time when the new Labour government is trying to kick start growth.In the five years to October 2024, the Environment Agency intervened on 60 occasions to object to planning applications due to the pressures they would place on local sewerage systems, according to a Freedom of
All American Marine Delivers Cal Poly Humboldt Catamaran
filters and meets California’s stringent environmental standards while delivering exceptional performance. The vessel is capable of fully laden cruising at speeds exceeding 28 knots at 80% engine load.Featuring Teknicraft’s signature hydrofoil-assisted hull design, the vessel minimizes drag, enhances fuel economy, and ensures a smoother ride in rough seas. Its CFD-modeled hull shape reduces wake energy and optimizes efficiency, a critical feature for long-duration research missions.Outfitted with a Kongsberg ADCP electronics suite, a fixed WASSP multibeam system, and Okeanus deck handling
Drag Marks Found on Baltic Seabed After Finland-Estonia Interconnector Damage
Finnish police said on Sunday they had found tracks that drag on for dozens of kilometres along the bottom of the Baltic Sea where a tanker carrying Russian oil is suspected of breaking a power line and four telecoms cables with its anchor.The Cook Islands-registered Eagle S was boarded by Finnish police and coast guard officials on Thursday and sailed into Finnish waters where the crew of the impounded tanker is being questioned.Baltic Sea nations have been on high alert after a string of outages of power cables, telecom links and gas pipelines since Russia invaded Ukraine in 2022. NATO said on
Marine Animals Travel at Depth that Minimizes Wave Formation
at the surface where wave generation is a major source of wasted energy. However, for marine birds, mammals and reptiles travelling great distances over their lifetimes, adaptation to minimize the energetic cost of transport is expected, particularly on long journeys.It has long been known that additional drag from wave creation minimizes once a travelling object is at depths greater than three times its diameter, but it was hard to compare with travel depths of wild animals due to tracking limitations.In this new study published in Proceedings of the National Academy of Sciences (PNAS) near surface swim
Mooreast Reels In $6.7M Multi-Buoy Mooring Upgrade Work Off Thailand
and distribution company.The project will begin in November 2024 and is expected to be completed by the first half of 2025.Mooreast will oversee the design, engineering, procurement, fabrication and installation of the multi-buoy mooring system.In addition, the company will supply their proprietary MA5P Drag Embedment Anchors, which offer a holding capacity of up to 275 metric tonnes, along with other mooring components which will be used to secure various offtake tankers, including those up to very large crude carriers (VLCC) size.Mooreast will also be handling the transportation and installation services
University of North Carolina Wilmington Orders Research Vessel from All American Marine
including oceanographic surveys, biological studies and educational outreach programs along the Mid-Atlantic, U.S. East Coast and offshore waters.The 73’ x 26.7’ aluminum catamaran, designed by Teknicraft Design in Auckland, New Zealand, incorporates a hydrofoil-assisted hull, ensuring reduced drag, enhanced fuel efficiency and passenger comfort. This dynamic hull design is optimized for stability and performance in various sea conditions. The vessel is designed to comply with U.S. Coast Guard (USCG) Subchapter T standards.Equipped with twin Scania Di16-082M EPA Tier 3 engines, each producing
All American Marine to Build Research Vessel for Cal Poly Humboldt
, as well as Offshore on Ocean Routes. The vessel integrates the signature Teknicraft Design symmetrical and asymmetrical combined hull shape, bow wave piercer, and a patented dynamic hydrofoil-assisted hull design. The hull and hull components are designed to break up wave action and ensure reduced drag while enhancing passenger comfort. This design is proven to have both low-wake wash energy and increased fuel economy. For the operator, the most valuable feature is the excellent fuel economy, which consumes approximately the same gallons per nautical mile throughout the estimated cruising speed
Mooreast to Anchor Floating Offshore Wind Farm in Southern France
Singapore-based mooring and anchoring specialist Mooreast Holdings has secured an order to supply its proprietary anchors for Eolmed pre-commercial floating offshore wind farm.Mooreast has partnered with French installation contractor Bourbon Offshore to supply Mooreast’s MA5S mooring drag anchors for the Eolmed project located off the Port-La Nouvelle and Gruissan in Southern France.Bourbon will provide transport and installation services to the 30MW pre-commercial project, which is being developed by Qair, a European independent energy company, with TotalEnergies and floating technology
