Weight of drilling platform energy storage device

Can electric energy storage systems be used for drilling rigs?

The work to develop electric energy storage systems for drilling rigs has been underway worldwide for the last 5 years, however, mainly targeting isolated offshore rigs.

Which rigs have energy storage systems for onshore drilling?

The energy storage system developed for onshore drilling is among the world’s first ones. As a foreign analog, only the project of the German rig manufacturer Bentec implemented in Oman can be highlighted. In 2017, the container-type 0.9 MW Bentec ESS with a storage capacity of 0.3 MW was put into trial operation on the KCA Deuteg T-94 rig.

Can energy storage systems improve energy eficiency of DPS-powered rigs?

Based on average daily power consumption statistics and load diagrams for various rig operating modes at more than fifty pads equipped with DPS, it was proposed to improve the energy eficiency of individual DPS-powered rigs by introducing energy storage systems (Fig. 1).

Can electric energy storage be used for drilling based on electric-chemical generators?

The article outlines development of an electric energy storage system for drilling based on electric-chemical generators. Description and generalization are given for the main objectives for this system when used on drilling rigs isolated within a single pad, whether these are fed from diesel gensets, gas piston power plants, or 6–10 kV HV lines.

What is a Subsea energy storage system?

The subsea energy storage system consists of the following main elements: storage units, a fluid transfer and refilling system, heating and circulation system, control and instrumentation, power supply, and structure and foundation. An example with a fixed platform with five 5,000 m³ storage units, gives a total storage volume of 25,000 m³.

How to reduce the cost of oil drilling rig lifting system?

An effective approach to reduce the cost of an oil drilling rig lifting system is recycling the energy during the process of lowering drill string and casing. In the present work, for a multi-model drilling rig, the total energy recovery and energy-saving ratio are calculated with considering the effect of hook without loading.
