Eimskip delivers perishables to Port of Portland …and beyond
By George Lauriat
In the Port of Portland, Maine, Eimskip’s weekly 
Green Line calls deliver cargos of temperature–con-
trolled perishables, like fresh salmon and other seafood, 
destined for dinner tables near and far. 
Eimskip, an Icelandic ocean carrier, is well-estab-
lished on the North Atlantic and from the carrier’s home 
in Reykjavik, Iceland the ocean carrier’s vessels call at a 
rotation of ports such as Argentia in Newfoundland, Nuuk 
in Greenland, Thorshavn in the Faroe Islands, or Batsfjord 
and Kirkenes in far northern Norway. Equally, Eimskip’s 
vessels also service well-known ports in Europe, while 
in the United States, Eimskip calls the Port of Portland, 
Maine its homeport and gateway for perishables.
Eimskip’s Dual Role with IMT
In the Port of Portland, Eimskip has a dual role; both 
as the terminal operator of the International Marine Terminal 
(IMT) in Portland as well as the operator of the ocean carrier 
Green Line service, which calls weekly at the terminal. 
IMT is in midst of upgrading the terminal, aimed at 
improving the facility’s ability to handle perishables in 
reefer containers.
Gylfi Sigfússon, CEO of Eimskip USA, said of the 
ongoing work, “The Port Authority in Portland, Maine 
is planning with us a significant upgrade to the reefer 
infrastructure in 2027, with the installation of 200-new 
reefer plugs. This will allow us to consolidate all refrig-
erated containers into a single, dedicated area, which is 
a major improvement compared to today, where reefers 
are spread across different parts of the port.” Adding, 
that “Currently, we use an average of around 100-reef-
ers plugged per day, so this expansion not only improves 
operational efficiency but also positions us well for future 
growth in line with our future needs.
As Sigfússon explains, the reefer plugs are designed 
for short-term use and typically containers remain 
plugged in for three-to-five days. For importers of perish-
able cargos, this provides flexibility while they determine 
the next step in the supply chain. For an exporter having 
the reefer plugs on site ensures the perishable cargo is 
properly refrigerated and ready ahead of vessel departure. 
Besides the reefer plugs, there has been other on-ter-
minal equipment and infrastructure upgrades at IMT. 
“We also have ongoing investments at the port in equip-
ment and infrastructure to support our growth. The Port 
is planning to add two new reach stackers, along with 
two additional yard trucks—to strengthen our opera-
tional efficiency and capacity,” Sigfússon, noted. He also 
pointed out that “In parallel, the port recently completed 
several infrastructure improvements, including upgrades 
to the bollards and dredging work. Our next focus with 
the Port Authority is on rehabilitating the terminal’s sur-
face with asphalt improvements planned to enhance both 
safety and efficiency across the yard.”
Another critically important project at IMT was the 
dredging of the vessel berths to 35-feet, the same as the 
Federal main channel at the port. 
“Maintaining the 35-foot channel depth represents 
an important investment in the port’s long-term compet-
itiveness and operational flexibility. The improved depth 
enables us to safely accommodate modern vessel sizes, 
enhance scheduling reliability, and support continued ser-
vice growth,” Sigfússon said of the dredging project.  But 
dredging represents a fundamental element in a termi-
nal’s ship handling capabilities, and as Sigfússon points 
out. “Just as importantly, this isn’t only about growth—
it’s about maintaining the level of service we already pro-
vide…. Without regular dredging, natural sedimentation 
would gradually reduce the depth, limiting vessel access, 
restricting cargo volumes, and ultimately impacting the 
reliability of our operations.” “By preserving this depth, 
we ensure consistent access for carriers, avoid tidal or 
draft restrictions, and provide greater flexibility in vessel 
scheduling. It also strengthens the port’s competitiveness, 
making it a more attractive and reliable option for ship-
ping lines and customers.
The Green Line Delivers
The “Green Line” service links the US via a first 
inbound call at the IMT terminal, to Europe via Reykja-
vik, Iceland. And as the company’s principal connecting 
service, the Green Line anchors all Eimskip USA’s North 
American activities. 
Sigfússon, said that currently Eimskip’s Green Line 
serves, “the North American market with three vessels, 
each typically carrying between 700 and 1,000 TEUs. 
Our first port call on the North America route is Portland, 
Maine, followed by Halifax, Nova Scotia, and Argentia in 
Newfoundland and Labrador on the eastbound leg. 
Sigfússon says the logic behind the Green Line’s 
rotation is that, “This route gives us the fastest possible 
route to get fresh fish to the market in US and the oppor-
tunity to shift some cargo that is currently being trucked 
to Canada onto our vessels, providing an efficient short-
sea shipping option between the US and Atlantic Canada 
and Newfoundland and Labrador.”
Keeping a weekly schedule on the North Atlantic is 
difficult and very hard during the winter months. This 
requires ships that can take whatever the North Atlan-
tic hands out year-round. According to Sigfússon, “The 
ideal vessels for this service are similar to our Bakkafoss 
vessel, which has a capacity of 1,025 TEUs. Having three 
vessels of that size would be perfect, but in practice, we 
adjust our capacity to match demand and remain as flexi-
ble as possible to meet our customers’ needs.”
The Green Line’s three-ship rotation has proved to 
be successful for Eimskip and the Port of Portland. As 
Sigfússon said of 2025, “The year began with strong 
momentum and, despite evolving trade conditions and 
tariff impacts later in the year, we achieved overall 
volume growth of approximately 3%. This result reflects 
the resilience of our service and customer base.”
And 2026 is looking positive despite the headwinds. 
Sigfússon said of the prospects for 2026, “We always have 
some challenges in the beginning of the year, but March 
showed strong volume and what we have seen into April is 
very promising. Overall, we are on similar level as last year, 
but last year same time we were not affected by tariff…. But 
what we are seeing in our crystal ball is very promising, the 
growth in the fish proteins from Europe heading for USA,” 
and an increase in seafood to the US likely means more reef-
ers for Eimskip and the Port of Portland.
