Objective
The aim of the project was the examination of the application of the "multiwell offshore shuttle tanker" (MOST) concept for oil production in deep water (400 metres) and severe marine environments such as those of the Eastern Atlantic Ocean.
The project was only a preliminary study; for principally economic reasons it has not proved justifiable to proceed with further work at this time.
The project was an examination of the application of the MOST concept, consisting of :
- a number of subsea-completed satellite wells connected to a manifold;
- a dynamically-positioned ship for use as a production tanker vessel containing all field process and storage facilities;
- deployable riser connecting the production tanker to the subsea manifold;
- use of the production vessel as a periodic shuttle tanker to a shore terminal.
- system to be capable to operation in 400 metres water depth;
- system to give commercially-acceptable production regularity in North Atlantic weather conditions, though not necessarily with year-round operation. Technical solutions in many of the problem areas involved in the development of this concept were examined and assessed, particularly in the areas of :
- subsea completion systems;
- riser systems;
- vessel motion performance and station-keeping;
- estimation of production system regularity and downtime.
Certain economic data, particularly as regards capital and operating costs, were also produced.
