Claim 1

Battery weight is one of the largest technical barriers to the energy transition of fishing boats. An Icelandic fishing vessel between 15 and 25 meters often requires batteries weighing between 10 and 30 tons to achieve energy capacity comparable to that of a diesel-powered vessel for a 10- to 12-hour voyage, and this directly affects the vessel's cargo capacity and stability.

Claim 2

The effects of cold on batteries are well known and measurable. At 0 degrees Celsius, the usable power of a battery pack can decrease by 20 to 40 percent compared to its value at 25 degrees, and this applies to common lithium-ion systems. This reduction is temporary and particularly noticeable when batteries are cold at the start of a voyage, but they warm up during operation.

Claim 3

The full electrification of Icelandic fishing boats is practically a solved issue from a technical standpoint. AI calculations show that the energy demand is measurable, battery technology is mature, and charging infrastructure has developed so much in recent years that the technical side of electrification no longer stands in the way.

Claim 4

According to data from the Nordic Maritime Administration, up to 74 percent of all new fishing vessels registered in the Nordic countries in 2022 and 2023 were equipped with some form of electric auxiliary equipment or hybrid propulsion systems, and this trend is coming to Iceland in a similar way.

Claim 5

Maritime safety must never be sacrificed for efficiency or cost-effectiveness during the energy transition. Captains may rely on electric technology to automatically take over control when the weather worsens, because automation and AI control are more precise than human judgment under stress.

Claim 6

Charging infrastructure in Iceland varies greatly by region. In Reykjavík and the larger capital area, fast-charging stations for vessels are under development or planned, but in small fishing villages and remote harbors in the north and east, such stations are mostly absent or in the research phase. This means that the energy transition is progressing unevenly across regions, vessel types, and operational models.

Compare answers

Here you see two different ways to ask the AI for the same thing. Choose the answer you trust more and write a short justification, and the explanation will open.

Comparison 1 of 2

Prompt

Compare two ways of asking an AI to analyze whether electrification is suitable for a specific 18-meter Icelandic fishing vessel, one without structure and the other with clear assumptions about the vessel, voyages, and safety requirements.

Answer A

Is it possible to put electricity in a fishing boat? This would be so good for the environment and the technology has come a long way. Maybe AI could help calculate this.

Answer B

The boat is 18 meters, diesel-powered with 220 kW of power, and operates day trips between 10 and 14 hours a day in Breiðafjörður, with two crew members on board. The harbor is Stykkishólmur, where no charging station is available. You are required to always have 30 percent reserve energy for safety. Calculate the energy demand, battery weight, impact on cargo capacity, and what is missing in the charging infrastructure. Mark which assumptions are uncertain and require confirmation from shipbuilders or electrical engineers.

Comparison 2 of 2

Prompt

Compare two ways of using AI to assess whether a specific retrofit is safe, one where the AI decides and the other where the AI lists assumptions and the student makes the decision.

Answer A

The AI said that the retrofit was safe according to its calculations. It calculated the energy demand and concluded that it would work well. Therefore, we could proceed with it.

Answer B

The AI returned a list of five assumptions that need to be verified: (1) that the battery pack holds DNV GL safety certification for marine use, (2) that the weight increase does not exceed 8 tons without a review of stability calculations, (3) that reserve power is available in accordance with the requirements of the Icelandic Transport Authority, (4) that sea trials are conducted at 2 Bft or more before full operation begins, and (5) that the captain receives specific training on the new system. We will make a decision on how to proceed after a specialist has reviewed these assumptions.
