Objective
This research project is aimed at studying the feasibility of hydrocarbon production systems for Arctic waters and their preliminary design.
Main results can be summarized as follows:
- Acquisition of environmental conditions or Arctic and Sub-Arctic
offshore areas.
- Acquisition of different formulation in evaluating the loads due to
the static or almost static and dynamic ice-structure interaction.
- Identification of possible problems on platforms in earthquake conditions
and methodologies to be used in seismic analysis in arctic conditions.
- The most promising Arctic offshore exploitation scenarios have been
identified and design premises for feasibility studies have been performed
- In feasibility studies the following three different production systems
have been identified feasible :
. RAP (Removable Arctic Platform) for Arctic seas (Beaufort and Russian
Barents sea) characterized by water depths in the range of 25-80 metres and
severe ice conditions
. TSG (Tecnomare Steel Gravity) platform for Sub-Arctic areas (Bering and
Okhotsk seas) characterized by water depths in the range of 20-60 meters
with severe seismic and moderate ice conditions.
. FPS (Floating Production Systems) for Sub-Arctic seas (South-East Canada
and Barents seas) characterized by iceberg and severe environmental
conditions.
- Design premises for preliminary design of a fixed steel gravity platform
for Okhotsk Sea and floating production system for South East Canada have
been performed.
- A procedure for Ice Management have been identified.
- A seismic analysis procedure have been developed.
- Preliminary analysis of TSG concept for shallow water areas has been
performed.
- Preliminary analysis of FPS for Sub-Arctic seas has been performed
following the Ice Management Approach.
- Economical analysis for both TSG and FPS has been performed to define
conditions of interest for applications.
The project is divided in 2 phases :
- The first include : A) Analysis of the basic problems posed by Artic, such as the definition of the environmental data, the ice/structure and ground/structure interactions; B) Feasibility studies of some production systems suitable for the most interesting areas.
- The second phase includes preliminary design of some production systems identified in feasibility studies.
