Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency

manufacturers typically provide enough information about fuel consumption across the engine’s RPM and power range so that we can reliably predict fuel use for any application. A plot of this distribution is often called a “fuel map”, but let me have you think of it as an output-to-input energy “efficiency map”.Unfortunately, we have a completely different circumstance when using PMSM drives. Confusion can arise because the generated benefit of the motor and the fuel used by the motor share the term “power” – one being the output mechanical shaft power (that

Amman Mineral Orders Forum ROV for Subsea Mining Support

Indonesian mining firm Amman Mineral has ordered an ROV from Forum Energy Technologies to support its mining operations at Indonesia's second-largest copper and gold mine.Forum Energy Technologies said Friday that, under the order, it would supply one of its observation-class remotely operated vehicles (ROVs), to be deployed at Batu Hijau on the island of Sumbawa, Indonesia, for subsea mining operations. The Sub-Atlantic brand Super Mohawk II ROV system will be equipped with two five-function manipulator arms for complex underwater procedures. The new asset will replace the company’s

Nido Robotics Debuts Two Underwater Drones

lateral inspections of nets and cages, and oversee mort lift processes. The drones’ capacity to assist divers in safely preparing and carrying out detailed, environmentally-conscious subsea inspection and maintenance operations is also of significant value in ports and marinas as well as the energy provision sector, with offshore oil & gas, wind, solar, nuclear and hydro platforms and installations which all feature submerged infrastructure.The small size of Nido Robotics’ drones has also proved advantageous in inspecting the interiors of tanks in water treatment stations, checking

U.S. to send envoy to Saudi Arabia to Stabilize Oil Prices

The Trump administration plans to send a special energy envoy to Saudi Arabia to work with the kingdom on stabilizing the global oil market, officials said on Friday, as the U.S. scrambles to deal with a price crash so deep that regulators in Texas considered curbing production there for the first time in nearly 50 years.Oil prices have lost more than half their value in the last two weeks as Saudi Arabia and Russia kicked off a price war and the coronavirus pandemic destroyed demand. U.S. oil now trades at less than $23 a barrel.The crash has shocked the oil industry as a pact among OPEC and non-OPEC

Neptune Energy Taps Stinger for Subsea Drone R&D

Subsea marine robotics company Stinger Technology has won a subsea drone research and development contract with oil firm Neptune Energy.Under the contract, Stinger Technology will work on the development, qualification and field trials of autonomous inspection/ intervention subsea drones."The solutions that will be developed for Neptune Energy aim to save costly vessel operations and reduce risk through the continuous availability of versatile intervention tools," Stinger said."This contract confirms Stinger’s position as a forefront company as a supplier of solutions for autonomous

The survey of Ikka Fjord was conducted between the 20th and 21st June 2019, with the first day spent partly on training and familiarizng the cox with the survey requirements and reconnaissance to identify navigation hazards in the fjord caused by the columns and rock skerries as well as some acquisition. The second day was spent entirely on acquisition followed by demobilization of the spread from ‘Siku’. Image: Courtesy Norbit

new technology for monitoring Floating Offshore Wind Turbines (FOWT).  As one of eight projects to benefit from a share of £1m from The Carbon Trust, the project will see the development of a highly efficient method for measuring fatigue and detecting anomalies in real-time for the renewable energy sector, AS Mosley said Monday.The system has the potential to vastly reduce operating costs by lowering – or potentially replacing – the need for subsea visual inspection of mooring lines for FOWT, the company said.The funding was won as part of a competition run by The Carbon Trust,
