Floating Terminals

global warming due to GHG emissions. The transport of the captured CO2 to the storage sites requires transport facilities such as a pipeline, ships or a combination of these. Ship transport requires in addition to the ship, a loading/unloading terminal. A CO2 terminal for shipping will as a minimum include docking facilities for the ship and loading/unloading facilities for the CO2. In addition, intermediate storage and possibly also CO2 liquefaction may be located on the shipping terminal. The terminal may also offer bunkering facilities and shore power. This paper discusses a generic basis of design for the possibilities to have a floating terminal in a CO2 transport chain. There are many reasons why a floating terminal should be considered as an alternative to “land-based terminal”. One of the main and obvious reasons is that land area in major ports is often limited and expensive. If the terminal could utilize the sea area it may lead to reducing the costs and area needed. Other reasons for designing a floating terminal in a ship transport chain may be: • Deep water quays are limited, a floating terminal can provide deep water docking. • A floating terminal will most probably be a dedicated dock and as such reach increased regularity. • A floating terminal can be built and commissioned as a complete unit at a shipyard. • A floating terminal can be redeployed. Floating terminals may include different facilities and have different locations. This paper will describe a modular terminal system which can accommodate for different requirements. The possibility of CO2 liquefaction in combination with the regasification of LNG from a FSRU (Floating Storage and Regasification Unit) will also be explored. The simple idea is utilizing the advantage of “free” heat transfer between the two media, where one needs to be cooled down and the other being heated. This is a possible solution where a regasification unit is located in the vicinity of a CO2 capture site or hub. Two configurations based on the suggested modules will be developed. One of these will be part of a specific value chain under development. These elements are included: • Familiar cases (including land based as well) will be studied to develop a design basis for floating terminals and identify key elements and sizing • Possible integration with an FSRU is investigated • Focus is on the modularization as a tool to be able to scale the chosen solutions to cater for different shipping, storage and liquefaction volumes • The ship docking and hook up facilities arrangement including utilities is investigated • Two floater configurations will be designed • The shore connection design for the floating terminal will be investigated. This includes liquid CO2 for loading, CO2 gas return and necessary utilities The paper is providing a conceptual design showing the functions incorporated in such a floating terminal. In addition, a modular system for a floating CO2 terminal with a menu of different options for sheltered waters are presented
