What are the Key Drivers, Restraints, and Opportunities in the Asia Pacific Scrubber System Market?

Driving forces for the Asia Pacific Scrubber System Market have been stringent IMO 2020 sulphur cap regulations, accompanied by continued high price differential of bunker fuel over other fuel options. In an attempt to avoid the high cost of using low-sulphur fuel, ship owners retrofitted scrubbers to gain an immediate increase in voyage level operating profit for Asia-Europe and intra-Asia trade. This factor has also generated consistent orders, especially among tanking and bulker fleets, running on long-distance lanes.

A significant restraining factor has been regulatory inconsistencies among various ports, including widespread ban on open-loop discharge in coastal regions like China and South-East Asia. Asset risk is now becoming more significant and ship owners need to change or reconfigure scrubber system depending on ports they will call at, hence, increasing complexity and cost associated with ship owners' investment decision in retrofit; in result of this, some owners chose to defer installation plans, thereby, dampening short term revenue generation.

Key opportunity within the market is modernization of hybrid scrubbers combined with integration with digital compliance reporting solutions. Ship owners, from Singapore and South Korea in particular, are investing in systems that combine the functionality of scrubbers with software applications for tracking and reporting emission levels in real-time to feed into carbon reporting requirements. The transition of vendors to providing not just the hardware but also to long-term service contracts and revenue models based on performance will play a role.

What Has the Impact of Artificial Intelligence Been on the Asia Pacific Scrubber System Market?

Artificial Intelligence (AI) is being increasingly integrated into scrubber performance systems to enhance emission control and minimize the uncertainty involved in maritime operations. Ship operators are now employing AI based control systems that allow automatic adaptation of washwater flow rates, the balance of fuel combustion and cleaning intensity of exhaust gases, depending on current engine load and thereby enhance the accuracy of compliance in all sea state conditions.

In relation to maintenance, the utilization of machine learning algorithms enables a forecast of the potential fouling risk or a components' deterioration, by processing sensor information relating to pumps, the levels of pH, and differential pressure readings. This enhancement has resulted in increased reliability of up time, while unscheduled maintenance operations, particularly in long-haul ships, and even more importantly, within the Asia Pacific Scrubber System market, have also decreased.

With regard to fuel efficiency and a forecast of emission levels, AI driven analytical platforms offer an improvement through simulating voyage conditions and optimizing the efficiency of scrubbers with varying fuel types. Operational costs are observed to have a directional decrease due to more efficient energy utilization and fewer manual adjustments. However, utilization is tempered by unreliable maritime communications for ship to shore data transmission while at sea. Further reasons are the associated high costs in implementing systems where new infrastructure, and a sensor rich data system for older vessels are required to allow for extensive utilization of AI based technology in exhaust gas cleaning.
