1,300-Tonne, 150-man Lift Barge with DP2

1,300-Tonne, 150-man Lift Barge with DP2

The platform is defined as a self-propelled Jack-up that is designed as according to a GustoMSC type NG-2500X which mainly designated for operation in worldwide ocean environments with sea water depths up to 70 m at all specified weather and the sea conditions stated in specification at that region. The unit is intended to be used as a basis for maintenance activities in oil and gas fields, and for permanent accommodation.

The prime operational functions of the Unit will be as follows:
1. Maintenance activities in oil and gas fields.
2. For permanent accommodation of 150 persons on board.
3. Wind Turbine Installation, Maintenance and Repair.

The unit is to be designed for 25 moves per year of a period of minimum 20 years.
The dynamic positioning system is executed for DPS-2 notation.
