Advanced Power Hybrid Propulsion Performance & Design, System Protection Optimisation Manufacturing and System Big Data Test

Asset Management Documentation & Micro Grid Generation Training Why AKA?

Since 1996 AKA has focused on delivering value based on these three elements. REDUCE ENVIRONMENTAL IMPACT We deliver solutions that reduce the environmental impact associated with the same operations.

INCREASE RELIABILITY Our systems provide a step change from the gold plate industry standard for system reliability. REDUCE OPERATING COSTS AKA provides the above increased reliability and reduced environmental impact while at the same reducing the cost of operation. 1st DNV DP3 Closed Bus Systems – Most References

MTBF for DP in the industry at 20 years... AKA provides 350 years and counting – most reliable. Some AKA Hybrid / ESS Milestones

2009 2019 World’s first Transocean Marine Hybrid Spitsbergen - System fitted on a hybrid propulsion Harbour Tugboat system (Carolyn Dorothy) starts operating 2015 2020 World’s first Seaspan Ferries – hybrid powered hybrid propulsion drilling system system 30% - 70% Reduction of Emissions

The Carolyn Dorothy is the worlds first hybrid tug and propulsion system design is patented by AKA. University of California and California Air & Resource Board conducted a study on emission results comparing the Carolyn Dorothy to a non-hybrid sister ship Alta June. Deepwater Thalassa

Scope of Supply

• High Reliability Power System Design Philosophy and Studies • Advanced Generator Protection (AGP) • SF6 11kV Switchboards • Advanced Thruster Control and Protection (ATCAP) • Drilling VFDs • Hybrid Drill Power System (70MJ) • Integrated System Documentation • Commissioning & Training • Implements Shell company wide LIFE concept (Low Impact Failure Effect)

>30% Fuel Savings to Comparable Vessels AGP - Advanced Generator Protection System AGP system is designed to improve Power Plant Robustness and improve the recovery from Bus Upset. Our AGP system can eliminate potential faults, increase fault detection, reduce effect of single fault and recover promptly from a fault, which makes the 6th generation Power Plant more reliable and robust.

Since 2011: Many successful short circuit tests on DNV class drilling ships with close ring DP3 system. The Path to AGP/Closed Bus

➢ Conventional Open Bus Solution The Path to AGP/Closed Bus

➢ Common Closed Bus Solution The Path to AGP/Closed Bus

➢ Intuitive Design – Elegance in Simplicity Short Circuit Test Reference List

Short circuit test is the most demanding test for close ring designed offshore ships/platforms. AKA’s track record proves AKA’s capabilities in system design, testing and in delivering the world’s most robust marine/offshore power propulsion systems.
