General information
Jackets were among the very first structures to be used in the offshore industry, as stable platforms mainly for oil and gas production facilities. Jackets are being used in shallow and medium water depth regions throughout the world. They can be built to withstand even extremely harsh environments, for example in the North Sea. The platforms range from very small structures carrying only meteorological measuring equipment to extremely large production platforms.

Services & Activities
The Offshore Department has been involved in model test and simulation projects concerning several design aspects specific to jackets. Many jacket launches from barges and up-ending operations using crane vessels have been carried out in our basins. Furthermore, the feasibility of a number of top-side installations, either by float-over installation or using a crane vessel has been investigated. In recent years also the decommissioning of platforms has also become an issue that needs to be considered.
The Trials & Monitoring Department has been involved in full-scale measurements during transportation of jackets on a barge. Vessel motions and accelerations, as well as sea-fasting loads were measured and analysed.

Jackets are tested in the following MARIN facilities:
- Offshore Basin: DP model tests in combined current, waves and wind
- Shallow Water Basin: DP model tests in combined current, waves and wind
- Seakeeping and Manoeuvring Basin: model tests in waves
The behaviour of jackets is simulated with the following tools :
DIFFRAC: 3-D potential theory including wave diffraction
DRIFTP/DBDRIFT: Second order wave excited (drift) forces
LIFSIM/LIFMOT: Analysis of multi body dyamics and lift operations
WINDOS: Assessment of wind loads on ships and offshore structures
