Foundation
► The core foundation for the development of the Frigstad D90 is founder and chairman, Mr Harald Frigstad’s decision to realize his ambition todesign and build the ultimate drilling rig, making use of the practical,
hands-on experience gained during a 15-year career of workingoffshore.
► The quest for energy drives exploration activities into deeper and
deeper waters, and consequently the challenges faced by drillingcontractors change and become more demanding.
► Rising costs of large scale offshore projects means that efficiency of the drilling units has become ever important.
► Extensive research, testing and implementation of innovative andefficiency enhancing features has resulted in a rig design which istailored to meet these demands of the future.

Frigstad D90 : Responding to future demands
Most drilling rigs in operation and under construction today are
based on generic hull designs which have been made to serve
different purposes.
Production, accommodation, drilling, heavy lift, pipe laying,
intervention, transportation, storage etc etc….
In order to respond to the new market trends and demands, the
Frigstad D90 has been developed from scratch, & with one sole
objective:
To provide an optimal tool for ultra deepwater
drilling and development operations.

Frigstad D90 : Optimising rig design
So, Frigstad Engineering set out to design the ultimate drilling rig from
scratch, not depending on any existing generic hull designs.
Which gave the team the luxury of starting with a blank sheet of paper.
Certain core parameters were at the top of the priority list, such as
- Drilling performance and efficiency
- High variable load
- Large deck space
- Safe & easy logistics
- Low cost; both to build and operate.- Cover majority of the world’s deepwater areas

Frigstad D90 : Optimising rig design
- Frigstad Engineering started with what we regard as the most
important component of a drilling rig; the drilling systems.
- We worked together with Aker MH for years to further develop their Dual Ram Rig concept into a customised solution for the Frigstad D90,
focussing on certain core properties of the drilling system:
- High capacities & a user friendly man-machine interface.

Frigstad D90 : Optimising rig design
The Dual Ram Rig supports our ultimate objectives and helps us achieve i.a: - Efficiency in the drilling operations; dual activity, offline pipe handling.
- Safety; equipment pushed from drill floor by hydraulic cylinders rather
than suspended by wire from top of derrick. No slip and cut.- Lower weight & lower centre of gravity; higher variable deck load.
- Cost efficient maintenance.

Frigstad D90 : Optimising rig design
In short, the rig has been designed specifically to support the drilling systems
and operations.
The end result of this holistic philosophy is a solution where the various
aspects of the drilling rig can be customised to suit the purpose, thereby
avoiding many compromises and sub-optimal utilisation of resources and
equipment applications.

Anchor winches below deck
The Frigstad D90 is designed with DP-3 system, and prepared for pre-set
mooring spread. In addition, the rig can be equipped for a conventionalchain/wire mooring system.
All the anchor winches have been placed below deck. This saves deck space,eases maintenance and reduces wear and tear on equipment.
