Singapore-registered “Dali” crashing into Baltimore bridge

National Transportation Safety Board (NTSB) on Tuesday (14 May) has dismissed contaminated bunker fuel as a cause behind Singapore-registered Dali crashing into Francis Scott Key bridge in Baltimore, Maryland, USA in its latest report. 

This was the latest finding of NTSB in its preliminary report, titled Contact of Containership Dali with the Francis Scott Key Bridge and Subsequent Bridge Collapse, investigating the fatal incident.

The vessel struck the Francis Scott Key bridge in Baltimore, Maryland, USA, on 26 March at about 1.30pm (Singapore Time), causing the bridge to collapse. 

Following the collision which killed six people, speculation was rife whether contaminated bunker fuel played a role in the containership losing power and crashing into the bridge. 

NTSB found that the ship used three main grades of bunker fuel for the main engine and electrical generators: low-sulphur marine gas oil (LSMGO), low-sulphur heavy fuel oil, and heavy fuel oil. 

Dali carried an estimated 1.8 million gallons of fuel in dedicated vessel fuel tanks. None of the vessel’s dedicated fuel tanks were damaged. 

The last time Dali crew switched fuel was on the evening of 21 March, five days before the accident, when they switched to burning LSMGO in all engines upon entering US territorial waters (12 miles off the Atlantic coast), as required by emission regulatory requirements.

The containership took on various amounts of all three types of fuel in Newark, New Jersey, on 19 March after the month-long trip from Sri Lanka. Fuel-sample analysis results indicated that the LSMGO fuel bunkered in Newark, which was the same type of fuel in use during the accident events, complied with international standards and regulations. 

According to the report, NTSB said: “The test results did not identify any concerns related to the quality of the fuel.”

On 28 March, the owner of the ship took samples of the LSMGO that was being burned at the time of the accident. At NTSB direction, the owner transferred the samples to an independent laboratory. 

“The test results did not identify any concerns related to the quality of the fuel,” it said.

On 11 April, additional fuel samples were taken from all fuel tanks and various fuel supply manifolds on board the vessel; samples were tested by an independent lab. 

“Fuel-sample analysis results indicated that the LSMGO fuel being burned at the time of the accident complied with international standards and regulations. The test results did not identify any concerns related to the quality of the fuel,” NTSB added. 

First series of blackouts when in port

Instead, NTSB found Dali experienced two electrical blackouts 10 hours before leaving Baltimore on 25 March during in-port maintenance. The first in-port blackout was caused by the mechanical blocking of the online generator’s exhaust gas stack. The second blackout in port was related to insufficient fuel pressure for the online generator.

NTSB also found Dali experienced two electrical blackouts when it was leaving Port of Baltimore when electrical breakers that fed most of the vessel’s equipment and lighting unexpectedly tripped.

The NTSB is still investigating the electrical configuration following the first in-port blackout and potential impacts on the events during the accident voyage.

It also said it will continue evaluating the design and operation of Dali’s power distribution system including its breakers.

“NTSB is working with parties to immediately assess their bridges and determine whether pier protection needs to be improved,” it added.

Singapore-based Grace Ocean Private Limited, the vessel’s owner, owns 55 ships—a mix of containerships including Dali, bulk carriers, and tankers. 

As of 26 March, Singapore-based Synergy Marine Group, the vessel manager who provided the crew and operated the vessel for the owner, managed 55 ships under Panama, Marshall Islands, Hong Kong, Liberia, and Singapore flags, including Dali.

Klaipėda Port launches Lithuania’s first hydrogen-powered vessel

Klaipėda State Seaport Authority on Wednesday (22 January) said the first ever green hydrogen and electricity-powered ship in Lithuania has been moved from shipyard into water. 

Leaving no trace on the environment, it will clean other vessels entering the port, accepting waste from them.

According to the current rules, vessels are obliged to hand over the waste they produce when they arrive and before they leave Klaipėda Port. The Seaport Authority was entrusted with the collection of the waste, and the company decided to use modern and environmentally friendly equipment to further improve the quality of the ship waste collection service.

The tanker’s main function is to collect storm water, sewage, sludge and garbage, as well as to ensure efficient waste management. The ship will be equipped with special tanks and a modern rainwater treatment plant that will allow the treated water to be transferred to the city’s sewage treatment plants. The tanker will be ready to work around the clock and collect up to 400 cubic metres of liquid waste.

The tanker is 42 metres long and 10 metres wide. The ship’s power system will consist of two electric motors powered by 2,000 kWh batteries and a hydrogen fuel cell system. Depending on the intensity of the work, the tanker will be able to operate in the port of Klaipėda for up to 36 hours without additional power charging.

This ship building project with a total value of EUR 12 million (USD 12.5 million) has been commissioned by the Port Authority and is being built by West Baltic Shipyard together with Baltic Workboats under a joint operating agreement.

“We have not only launched a tanker, but also a new approach to port operations – cleaner, smarter and more environmentally friendly. This first ever hydrogen and electricity-powered ship is not only an innovative technological solution, but also an important step in strengthening Lithuania’s image as a modern maritime nation,” said Algis Latakas, Director General of Klaipėda State Seaport Authority.

“At the moment, the tanker is getting used to the seaport water, so to speak, and at the end of the year we expect it to start its important mission of taking care of the clean seaport environment. Such a decision will not leave a footprint on nature, but it will certainly leave a strong mark on our path to a greener future.”

In June last year, a symbolic keel-laying ceremony at the West Baltic Shipyard of the West Baltic Shipyard Group marked the start of the ship’s construction. To date, the hull has been fabricated and painted, with piping, valves, coolers, shaft lines, rudder feathers, heat and fire insulation installed.

Once the tanker is moved into the water, the engine room equipment will be installed, the interior of the wheelhouse will be redecorated, the electrical wiring and the main electrical engines will be installed, the hydrogen system will be installed and other work necessary for the operation of the ship will be carried out.

Dublin Bay Cruises opts for HVO bunker fuel to power passenger ship “St. Bridget”

Dublin Bay Cruises on Wednesday (22 January) announced the launch of its eco-friendly initiative by moving from fossil fuels to Hydrogenated Vegetable Oil (HVO) in their existing passenger ship St. Bridget

The company said it is now the first domestic passenger ship operator in Ireland to adopt this sustainable practice aimed at reducing environmental impact while enhancing the marine experience for visitors.

In adapting the Circular Economy Policy they have remanufactured the engines of St Bridget, making her more fuel-efficient, and dramatically reducing emissions. By doing this, instead of building from scratch, they not only reduced waste but also took a major step toward a greener future.

This change will reduce emissions by up to 90%, which will exceed the climate targets set by the EU and Ireland. This thoughtful investment underscores Dublin Bay Cruises’ commitment to environmental stewardship and sustainable tourism.

“Recently Dublin Bay Cruises faced a crucial decision—whether to invest in a larger vessel for increased passenger numbers or to reconsider our approach and focus on sustainability,” said founder and Managing Director Eugene Garrihy.

“After careful thought, we chose the latter. Our choice reflects not just a business decision, but a responsibility to the environment and the future of our coastal communities. We need to slow things down.”

Garrihy added: “We are deeply aware of the privilege and responsibility we have to operate in UNESCOs Dublin Bay Biosphere, one of the most beautiful marine environments in the world. This initiative is a reflection of our commitment to preserving Dublin Bay for future generations while still providing our customers with an unforgettable and sustainable marine experience,”

The transition includes substantial investments in reducing carbon emissions, improving energy efficiency onboard with solar panels, and incorporating green technologies into its daily operations. Dublin Bay Cruises has also partnered with Failte Ireland’s “Climate Action Programme” and with local marine conservation groups to support biodiversity and the protection of the rich marine life found in Dublin Bay.

Being the first domestic passenger ship in Ireland to take this important step is not just a milestone for Dublin Bay Cruises, but also hopefully an encouragement for others working in tourism industries to take the leap and follow suit in safeguarding Ireland’s natural heritage.

The company added St. Bridget will now continue to serve as a passenger ship for at least another decade, with far fewer emissions than before.
