According to a new study, container ships can reduce fuel burn and resulting carbon emissions by 14 percent per voyage by utilizing just-in-time (JIT) arrivals.
JIT is an important tool that can help a ship achieve its required CO2 Intensity Indicator (CII) and associated CII rating under the International Maritime Organization’s (IMO) Short-Term Greenhouse Gas (GHG) Reduction Measure, which is published in Force will come into force later this year, the study added.
“JIT can be included along with other operational measures in the Enhanced Ship Energy Efficiency Management Plan (SEEMP), which will play a central role in the implementation of the IMO’s recent energy efficiency measures.”
The study commissioned by IMO-Norway GreenVoyage2050’s Global Industry Alliance to Support Low Carbon Shipping (Low Carbon GIA) and conducted by MarineTraffic and Energy and Environmental Research Associates (EERA) uses AIS data from calendar year 2019 (pre-pandemic) . to determine the impact of JIT on fuel consumption and emissions by optimizing trips in three scenarios:
*Throughout the trip,
* In the last 24 hours and
*In the last 12 hours.
“The results show that while optimizing speed over the entire duration of a trip offers the greatest savings opportunity (with an average fuel saving per trip of 14.16 percent), it benefits in all scenarios with savings of 5.90 percent (24- hourly scenario) and 4.23 percent (12-hour scenario). This indicates that implementing JIT in the last 12 hours of a voyage can already contribute significantly to fuel and emissions savings.”
“In the fight against climate change, global shipping has a steep climb to climb and we must pull out all the stops to comply with the Paris Agreement,” says Captain Andreas M. van der Wurff, Port Optimization Manager, AP Moller-Maersk and Chairman of the workstream Low Carbon GIA Ship-Port Interface. “The study underscores that while we are working to accelerate and scale the availability of future green fuels, significant emission reductions can be achieved in the short term by bringing ships, terminals and ports together to share standardized data and just-in-time -Facilitate arrivals. “
The Low Carbon GIA is a public-private partnership to develop innovative solutions and remove shared barriers to the decarbonization of the shipping sector.
Only 20 ships waiting in LA/LB ports
One of the main reasons for container ship delays used to be the ports of Los Angeles/Long Beach. A total of 20 container ships were backed up in ports yesterday, a new record low, according to data from Capt. J. Kipling (Kip) Louttit, executive director, Marine Exchange of Southern California & Vessel Traffic Service Los Angeles and Long Beach San Pedro, CA.
The 20 container ships secured include 0 container ships at anchor waiting for a berth off the ports of LA/LB/Huntington, + 0 loitering within 25 miles of the ports, + 20 at slow speed, waiting outside the Safety and Air Quality Area (SAQA) vaping or loitering.
The 20 container vessels in backup is 89 down from the record of 109 set on January 9, 2022. “To put it another way, 0 container vessels are within 25 miles of LA and LB awaiting berth which is great because normal before -COVID was 0-1.”
Ship delays are decreasing
While 10.5 percent of the world’s fleet is still unavailable due to supply chain delays, it’s down from 13.8 percent in January, Sea-Intelligence said in an update earlier this month.
“It is interesting that the overall congestion index in Europe has continuously improved significantly over the past month – although it should also be noted that despite the clearly visible decline, the level of congestion is still very high in comparison with normality before the pandemic.”
At the port level, significant improvements can be seen in Spain, Italy and Greece, while at the other end of the scale, Rotterdam and Hamburg have not seen much improvement, the Sea Intelligence report says.
