Pioneering exploratory geotechnical surveys for the construction of offshore wind farm Ossian have recently been completed, involving Ocean Infinity's new Infinity CPT 250. Read more >> https://hubs.la/Q0294fKq0 Ossian will have the potential to produce up to 3.6 gigawatts (GW) of energy, enough to power up to six million homes. Once completed, it will be one of the largest floating offshore wind farms in the world. Since spring 2023, Ocean Infinity has supported with detailed geotechnical surveys to assess the engineering properties of the seabed across the expansive site. Its scope included 90 seabed cone penetration tests (CPT), 45 seabed seismic cone penetration tests, and 20 vibrocores. Deep push seabed CPTs were carried out remotely in a significant industry first operation of its kind. ‘Over-the-horizon’ commands were sent via a remote-control system, which directed the successful operations of the Infinity CPT 250.

Monopile installation failed! Monopile foundation for offshore wind generators (VTG) Soft seabed substrate, the monopile usually needs to be driven in using a hydraulic hammer. In this cae it made it's own way down without any help! If it has gone too deep they won't be able to put the yellow transition piece TP, on top. That's the bit that the Wind Turbine Generator WTG is mounted on. Also might not be able to retrieve it! Could be an expensive failure... #Maritimelndustry #Shipping #Marine #Technology #Maritimelnnovation #Ocean #Transportation #PortsAndTerminals #MarineEngineering #MaritimeLogistics #MaritimeTrade #NavalArchitecture #Seafarers #MaritimeSafety #Oceanography #MaritimeLaw #MarineEnvironment #MaritimeEducation #MaritimeHistory #Shipbuilding #MaritimeEconomics #MaritimeSecurity #CruiseShipDepartures #ThrusterControl #MaritimeMastery #JourneyOfDiscovery #PassionForTheSea

It is not an exaggeration if we claim that #windenergy production is #inherentlysafer than O&G production. Despite this, every operation in an offshore #windpark needs to be carefully planned and executed. One of these operation is travel to and from a #WTG. #Helicopter transport to offshore wind turbine follows the same safe and proven-in-use techniques, procedures and machineries developed for the offshore O&G installations. However, there are some differences. Video shows a technician is hoisted down to #nascell of an offshore wind turbine to perform critical maintenance work. Such risky operation requires among others proper training, clear communication, parking of wind turbine in the correct position, state of the art helicopters and experienced pilots. Nothing will be left to chance or luck!

Subsea Installation concept The challenges and the issues of subsea installation may be classified in the following general areas: 1- Lifting and lowering technology - Those issues directly related to the weight of the loads to be lowered to the deep seabed, the dynamic responses that can augment these loads, and the capability of the lifting systems. 2- Load control and positioning - Issues related to placing the load in the desired location, at the correct compass heading, and at a stable attitude on the seabed. 3- Metocean (meteorological and oceanographic) effects and weather window requirements  In order to design and operate offshore installations in a safe and efficient manner it is essential that a good knowledge is available of the met ocean (meteorological and oceanographic) conditions to which the installation may be exposed. Of most importance is the wind, wave current and tidal conditions at the location of the installation. However, at some locations and for specific types of operations, other parameters may be important (e.g. air and sea temperature, visibility and ice conditions). #subsea #subseaengineering #offshore #offshoreoilandgas #oilandgasindustry

Hey all! A few years ago, while I was working at the Numerical Offshore Tank (TPN-USP), we started doing wave basin tests of floating offshore wind turbines to validate our numerical models. The main challenge of such tests is that you cannot physically scale both the hydrodynamic and the aerodynamic aspects of the problem at the same time — the waves like to hang out with Froude, but aerodynamics prefers Reynolds.   The solution we adopted was to use a software-in-the-loop approach (SIL) to account for both hydrodynamic and aerodynamic loads at the same time. The whole thing is explained in our recent Ocean Engineering paper (https://lnkd.in/eV3iG6E2 free access until August 09, 2024). In short, the idea is to split the problem into two parts: (i) a Froude-scaled floating platform in the wave basin, and (ii) a numerical model that is responsible for solving the aerodynamic loads in real time. The aerodynamic loads are applied on the floating platform using a set of actuators — in our case, a pair of wind propellers located at hub height. The resulting motions, due to both wind and waves, are measured and fed to the numerical model to account for the instantaneous position of the rotor and for the relative wind velocity at the virtual blades. Hopefully, the diagrams and explanations in the paper can make that clearer!   The underlying assumption is that we trust the aerodynamic model, which is fine in our case. As a wave basin, our goal is to investigate hydrodynamic phenomena — wind tunnels can do the opposite and use hybrid models where they focus on aerodynamic phenomena. In that paper, we use this experimental capability to investigate three important aspects of hydrodynamic numerical models: the importance of considering directional drag coefficients for the pontoons of the floating platform; the relevance of second-order resonant motions in both the horizontal and vertical planes; and the influence of floater tilt on the wave-induced dynamics. We also discuss the capabilities and limitations of the experimental method. Feel free to get in touch if you have any questions!   This work was developed under a R&D project in partnership with Petrobras to investigate and develop floating offshore wind turbines in deep waters.
