What is repurposing offshore pipeline as energy storage?

Repurposing offshore pipeline as energy storage (ROPES) is a concept that is being investigated by a partnership of offshore projects and services specialists Subsea 7 and offshore energy storage startup Flasc. Flasc was founded as a spinoff from the University of Malta in 2019 and is based in the Netherlands.

Why are oil-storage tanks drained?

(Bloomberg) -- Oil-storage tanks at a key US crude hub have drained to near their bottoms as a massive new pipeline in Canada diverts flows elsewhere, muddying market signals that traders have long relied on. Inventories in Cushing, Oklahoma, have been dwindling for the past four months and now sit near the lowest in a decade for this time of year.

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 pipelines be used as pressure vessels in Hydro-Pneumatic energy storage?

The partnership of Subsea 7 and Flasc has a plan to use out-of-service pipelines as pressure vessels in a hydro-pneumatic energy storage concept. The first Flasc HPES prototype deployed in Grand Harbour, Malta, in 2018. Source: Flasc.

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.
