Ship and a method for bringing liquified gas from an onshore terminal across a sea to a subsurface permanent storage reservoir

A ship for bringing liquified gas, such as liquified carbon dioxide, CO2, from an onshore terminal across a sea to a subsurface permanent storage reservoir, the ship comprising a loading line for communicating liquified gas received from the onshore terminal into a plurality of vessels onboard the ship, and a processing plant, wherein the processing plant comprises:

• an injection processing module comprising an injection pump configured for injecting the liquified gas into the subsurface permanent storage reservoir;
• wherein the injection processing module is operatively connected to the plurality of vessels and a gas injection line provided with a connector for connecting to a flexible injection hose extending from a subsea connection point being connected to a well of the subsurface permanent storage reservoir,
• wherein the ship is a shuttle tanker comprising a storage tank having a larger volume than the plurality of vessels, and wherein each vessel in the plurality of vessels includes a housing having a first portion housed within the storage tank and a second portion extending out of the storage tank and above a deck of the ship, and
• a liquifying processing module configured for liquifying gas, wherein the plurality of vessels is in loop communication with the liquifying processing module so that gas that is evaporated from the liquified gas in the plurality of vessels is liquified in the liquifying processing module and communicated back into the plurality of vessels.
