Western States Petroleum Association (WSPA) engaged DNV to conduct a technology assessment of the emissions control strategies considered in the 2020 amendments to California Air Resources Board’s (CARB) Ocean-Going Vessels At- Berth Regulation.
The technology assessment determines if the emissions control technologies can be designed for tanker vessels to comply with the regulation safely and reliably, while still meeting other applicable tanker regulations and standards.
DNV included an extensive array of subject matter experts and key stakeholders from government and public entities, industry and industry groupsfor a comprehensive assessment.
Over the course of multiple technical workshops, the experts discussed the current CARB-approved emission control technologies (CAECS):
The experts evaluated each CAECS and discussed in detail their degree of technical feasibility and maturity, safety concerns and safeguards, operational considerations, environmental aspects and regulatory dependencies.
More specifically, the report concludes that:
Shore power
Assessment of the shore power technology indicates that the technology needs further development for large-scale implementation in the tanker segment. Some of the key findings are the following:
Shore and barge based capture and control technology
The capture and control technology has certain unique risks relevant to its potential utilization on tankers. To mitigate the risks, the critical recommendations during the design, construction, and implementation are identified through this study. Third-party engineering firms have begun to understand and address these challenges with revised designs with focus on the barge based capture and control technology.
