Port of Seattle

Washington State Department of Ecology, the Port of Seattle, and Cruise Lines International Association Northwest & Canada (CLIA-NWC), on Tuesday (24 August) announced that there would be no changes to the voluntary agreement on cruise ship scrubber wastewater dumping in Puget Sound due to opposition by CLIA, according to environmental organisation Stand.

Instead, the Port of Seattle and Ecology proposed a temporary pause on scrubber wastewater dumping in Puget Sound while a third-party study is conducted.

The announcement came after a broad public outcry from tens of thousands of people who earlier this year participated in Ecology’s public comment period and spoke out in support of proposed amendments 

One amendment called for the state agency to ban cruise ship scrubber wastewater discharges in Puget Sound in order to address ongoing pollution concerns and better protect the endangered Southern Resident orcas.

During the comment period in early 2021, more than 24,600 people signed a petition in support of the amendments, 230 people submitted individual comments, and 10 environmental groups — Stand.earth, Friends of the Earth, Friends of the San Juans, James Bay Neighbourhood Association, Pacific Environment, Puget Soundkeeper Alliance, Seattle Cruise Control, Washington Environmental Council, Zero Waste Washington, and 350 Seattle — submitted a technical letter outlining their support for the scrubber amendment.

All three parties involved in the voluntary agreement had to agree to the amendments in order to update the agreement, called a Memorandum of Understanding (MOU). At a virtual meeting hosted by Ecology on Tuesday, August 24.

An Ecology representative stated that the decision was “certainly a tough one” but that the parties were “unable to reach consensus on the proposed amendment as written” to permanently ban scrubber wastewater in the MOU. A CLIA spokesperson confirmed the cruise industry lobbying group did not support the amendment.

The Port of Seattle and Ecology proposed instead a third-party study on scrubber wastewater discharges starting in 2022, alongside a temporary pause of scrubber wastewater discharges in Puget Sound while the study is completed. 

In response to the decision, environmental advocacy groups Stand.earth, Friends of the Earth, 350.org, Seattle Cruise Control, Puget Soundkeeper, Pacific Environment, and Friends of the San Juans issued the following statements:

“We are dismayed that the cruise industry has blocked Washington state from protecting the Puget Sound from cruise ship pollution. Scrubbers are a growing issue around the world, with several states and countries banning scrubber discharges due to their pollution impacts. Now, as the cruise industry returns after the COVID-19 pandemic, 

“Puget Sound waters will remain unprotected from these toxic discharges. We are calling on Gov. Inslee to step in and set this right,” said Anna Barford, Climate Campaigner at Stand.earth.

“Scrubbers are nothing more than emissions cheat systems that turn air pollution into water pollution by dumping toxin-laden wastewater into our oceans. Studies show that this pollution drives up the acidity of surrounding waters and harms marine wildlife and ecosystems, including the endangered Southern Resident orcas. It is way past time for the cruise industry to stop dumping toxic wastewater into our waters,” said Marcie Keever, Oceans and Vessels Program Director at Friends of the Earth.

“It is past time for our ports and state to recognize that the marine ecosystem cannot endlessly absorb pollution to protect the profit margin of certain industries. You can’t be pro-fish, pro-orca, and pro-scrubber,” said Miranda Marti, Co-lead of the Seattle Maritime Solutions Team at 350.org.

“Asking our kelp forests, fish, orcas, and people to pay the price for cruise ships to continue buying cheaper fuel and use scrubbers is unconscionable. This refusal to use available mitigation, such as burning low sulfur fuels, demonstrates why we need to transition away from the industry to a cruise-free Salish Sea,” said Stacy Oaks, Steering Committee member for Seattle Cruise Control. 

“This is a classic case of one step forward, one step back, and it’s leading to the continued governance stalemate hamstringing efforts to protect our local waterways and restore our local ecosystems,” said Blair Englebrecht, Boating Programs Manager at Puget Soundkeeper.“ 

Put simply, we are shocked at the eyes-wide-open nature of this decision doubling down on plans everyone admits will harm our coastal waterways; toxic discharges have no place in Puget Sound — or any waterway — especially when those discharges are readily preventable using existing technology.

“Cruise companies make their living bringing passengers to remarkable locations, yet they seem unwilling to do what’s needed to protect these very places. Heavily lobbied for by the cruise industry at the International Maritime Organization, scrubbers are a cheat. Rather than burning cleaner fuel, they made the calculation that installing scrubbers would save a few pennies over the lifetime of a vessel. Scrubber wastewater is acidic and full of contaminants like heavy metals, it has no business being dumped overboard anywhere — much less in sensitive areas like Puget Sound,” said Jim Gamble, Arctic Program Director for Pacific Environment.

“It is imperative that scrubber discharges be prohibited from the estuarine environment of the Salish Sea, which provides far more economic benefits to this region than the cruise industry does,” said Lovel Pratt, Marine Protection and Policy Director at Friends of the San Juans.”

“The public clearly sees how scrubber discharges are nothing more than a slight-of-hand: removing pollutants from the air we breathe only to dump them in the waters that sustain our lives.”

More and more cruise and cargo companies are beginning to install scrubbers on their ships in order to comply with the International Maritime Organization’s 2020 rule, which limits the sulphur content in the fuel oil burned to power ships operating outside designated emissions control areas. Sulphur oxide (SOx) emissions from ships burning bunker fuel have major health and environmental impacts. it states.

According to a recent study by the International Council on Clean Transportation (ICCT) focused on Canada’s Pacific coast, in 2017, 30 scrubber-equipped ships dumped 35 million tonnes of contaminated scrubber wastewater near British Columbia, including 3.3 million tonnes within the designated critical habitat for endangered Southern Resident orcas. 

Cruise ships were responsible for 90% of these discharges, with many of them leaving from Seattle on round trip voyages to Canada and Alaska.

Several states and countries already banned scrubber discharges in port or in inland waters, including California, Hawaii, and Connecticut, as well as Norway, China, Singapore, Belgium, and the United Arab Emirates.

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
