... Supercapacitors (or combinations of batteries with supercapacitors) in electric vehicles and hybrid electric/internal combustion engine vehicles in particular, have already paved the way for systems which offer far greater peak power than is normally provided by either the engine or batteries...

... Abstract The development of new resident and autonomous underwater vehicles (AUVs) has been enabled thanks to advances in secure and reliable Ethernet communication networks, software, batteries, and positioning sensors. Applying these technologies through a joint project between Oceaneering...

... often used because of the high robustness and safety; but hydraulics also include complex installation, low energy-efficiency and potential environmental risks. On the flipside, subsea electrification seems cost-intensive due to its high power and large batteries needed. This paper explains how a novel...

... the THRT functions. Since hydraulic pressure is generated by use of hydrostatic pressure, the subsea battery only needs to be sized to power the electronics. This allows for running the workstring, tested on deck, with pressurized THRT lock and TH unlock, if required. Preparation on deck is planned to have...

... In a hybrid power plants, excess power produced from the diesel gensets can be stored in batteries and used in various ways to improve facility performance– for example during times of peak loading. Unlike diesel generators, which are slow to handle large, abrupt load changes, the batteries can...

For example, resident autonomous underwater vehicles (AUVs) equipped with the optical transmitter would be able (i) to charge batteries of undersea sensors such as wellhead sensors and telemetry of well-monitoring...

... created during this 15-year journey. What has led the industry towards the solutions developed, how have those solutions lived up to their promises as far as lifetime and reliability are concerned? Why was it beneficial to store electric energy in batteries subsea for the operation of the system? and what...

... generation. The diesel generator only operates intermittent charging a battery bank. The operator is forced to shut-in production from any NUI if the NUI run out of power (stored in the accumulators and given that the diesel generator is unavailable). All the NUIs are equipped with LG delivered at 165 barg...

.... To date, most systems rely on large battery banks or oversized generators to supplement the renewable power. The shortcomings include cost, size, weight and maintenance. Tetra West Technology has conducted a series of technical studies in order to optimize the integration of renewable energy, back-up...
