Field Lifecycle and Wind Maintenance

The NG's are a series of multi-purpose jack-ups. These units undertake transit and positioning offshore without tug assistance. The four legs and diagonal preloading capability allow for easy, fast, and secure jacking and pre-loading operations.

The NG-5500X is intended for use in water depths of up to 55 m in a North Sea type rough environment and up to 75 m in a moderate type of environment. With this capability, the unit is able to cover all Southern North Sea fields.
