General
The Offloading Operability-JIP is a MARIN initiative for a Joint Industry Project to develop a simulation tool that can assist in the evaluation of:
1. The approach of an offloading tanker towards an FPSO.
2. Tandem offloading from an FPSO towards an offloading tanker
The tool is developed in close co-operation with oil companies, contractors, shipyards and classification societies. Operational people from these companies have a significant contribution in the specifications for the tool (what should the tool be able to predict and which information is required to make this prediction).

Background
Offloading operations can have a significant impact on the design, economics, operation and safety of FPSO systems:
· Weather downtime of the offloading effects the economic performance of the FPSO.
· The choice of the offloading system has a significant impact on the capital and operational expenditure.
· Safe day-to-day operation requires clear procedures and trained personnel.
· Offloading operations have a large safety impact, because they involve by definition the operation of two or more structures in close proximity.

Objectives
The objective of the present JIP is to develop and validate tools that can assist in:
· the evaluation of the design and operation,
· the assessment of limiting weather criteria, and
· the risk assessment of safety of offshore offloading operations.

Scope of work
· A reliable and user friendly tool will be developed that can simulate the offloading behaviour of hawser moored shuttle tankers and their approach to the FPSO or buoy.
· Wind tunnel tests will be carried out to investigate the important interaction effects in the current and wind loads of two vessels in close proximity.
· Research will be carried out to investigate the important interaction effects in the wave forces on two vessels in close proximity.
· Model tests will be used to validate the developed tool.
· The tool will be developed such that it can be used to support design as well as operational issues (and a combination of both).

deliverables
The project has the following deliverables to the participants:
· Executable version of the developed tools
· Report of wind and current load interaction experiments
· Reports of validation model tests and validation work
· CD Rom of model test time traces
· Summary video of model tests
The project will be completed with a training course with case studies.
