Oil Rig Energy Storage System

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.

How to reduce energy consumption of drilling rigs?

(DPS), or gas piston or gas turbine units (Pavk ović etal. 2016 ). As for the rigs, this energy consumption mode is POOH). introducing energy storage systems (F ig. 1 ). 1. Capital costs of powering drilling rigs are reduced with tings check once per shift. Also, the ESS does not need 2. The diesel fuel consumption will be reduced by up to 3.

Which rigs use lithium-ion energy storage?

The solution has been installed on various marine vessels worldwide, including the West Mira ultra-deep semi-submersible, the world’s first low-emissions drilling rig to use lithium-ion energy storage.

Why do drilling rigs need a permanent energy source?

An energy source permanently integrated into the rig circuit will allow drilling contractors to compensate for voltage dips and surges, which will reduce emergency shutdowns and downtime of drilling equipment (Chervonchenko and Frolov 2020), minimize drilling hazards, and improve the DPS operation stability.

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.

Can a hybrid energy accumulation system be integrated into a rig power circuit?

The efficiency of using a hybrid energy accumulation design is proven; the design calls for joint use of Li-ion cells and supercapacitors, as well as three-level inverters, to control the storage system. The article reviews all possible options for connecting the system into a unified rig power circuit, and the optimum solution is substantiated.
