Marine transportation occurrences in 2021

The TSB gathers and uses transportation occurrence data during the course of its investigations to analyze safety deficiencies and identify risks in the Canadian marine transportation system.

It should be noted that certain characteristics of the data constrain statistical analysis and identification of emerging trends. These include the small totals of accidents and incidents, the large variability in the data from year to year, and changes to regulations and definitions. The reader is cautioned to keep these limitations in mind when viewing this summary to avoid drawing conclusions that cannot be supported by statistical analysis.

The 2021 data were collected according to the reporting requirements described in the Transportation Safety Board Regulations in force during that calendar year.

The statistics presented here reflect the TSB Marine Safety Information System (MARSIS) database at 18 March 2022. Since the occurrence data are constantly being updated in the live database, the statistics may change slightly over time.

Also, as many occurrences are not formally investigated, information recorded on some occurrences may not have been verified.

Accidents

Overview of accidents and casualties

In 2021, 220 marine accidents^{Footnote 1} were reported to the TSB, down from the 2020 total of 264 and below the 10-year (2011–2020) average of 284 (Figure 1). In 2021 the proportion of shipping accidents (as opposed to accidents aboard ship) was 80% of marine accidents, comparable to the previous 10-year average of 82%.

There were 177 shipping accidents in 2021, down from the 2020 total of 221 and down 24% from the 2011–2020 average of 234. The majority of shipping accidents involved fishing vessels (25%), followed by solid cargo vessels (21%) (data not shown).

In 2021, there were 43 accidents aboard ship, unchanged from 43 in 2020 and down from the 2011–2020 average of 50. The majority of accidents aboard ship occurred on fishing vessels (53%) and cargo/tanker vessels (30%) (data not shown).

Casualties (tables 1, 6 and 7)

In 2021, 11 marine fatalities were reported, down from the 18 fatalities reported in 2020, and below the annual average of 15.6 in the 2011–2020 time period. Of the 11 fatalities in 2021, 9 were the result of 4 shipping accidents, while the remaining 2 fatalities resulted from accidents aboard ship (Figure 2).

Of note, 6 of the 9 shipping accident fatalities in 2021 involved commercial fishing vessels, and both of the fatalities that ensued from accidents aboard ship occurred aboard commercial fishing vessels. These data indicate that more still needs to be done to improve safety in the commercial fishing industry.

Serious injuries in 2021 totalled 45, up from 41 in 2020 but down from the annual average of 47 from 2011 to 2020. Forty of the 45 serious injuries (89%) resulted from accidents aboard ship, and 5 resulted from shipping accidents.

Shipping accidents

Type of accident (Table 1)

As illustrated in Figure 3, the most frequent types of shipping accidents in 2021 were collision (31% of all accident types reported), fire/explosion (25%), and grounding (20%). The total number of collisions (54) was 34% less than the 10-year (2011–2020) average of 82, the number of fire/explosion accidents (44) was 23% above the 10-year average of 36, and the number of groundings (36) was 40% below the 10-year average of 60.

Type of vessel (Table 1)

Forty-nine fishing vessels were involved in shipping accidents in 2021, down from 77 in 2020 and down from the 2011–2020 average of 84 (Figure 4). Fishing vessels represented one-quarter of all vessels involved in shipping accidents.

Geographical region (Table 2)

In 2021, 46% of shipping accidents occurred in the Pacific region, 30% in the Central region, and 24% in the Atlantic region. Less than 1% of shipping accidents were in foreign waters.^{Footnote 2} In the Pacific region in 2021, shipping accidents were 15% below the 2011–2020 average, in the Central region shipping accidents were 23% below the 2011–2020 average, and in the Atlantic region shipping accidents were 31% below the 2011–2020 average (Figure 5).

Twenty-eight fishing vessels were involved in shipping accidents in the Atlantic region, which is below the 2011–2020 average of 43 fishing vessels. Twenty-five cargo/tanker vessels were involved in shipping accidents in the Central region, below the 2011-2020 average of 39.  Twenty-four barge/tug vessels were involved in shipping accidents in the Pacific region, below the 2011–2020 average of 27 (Table 2).

Vessel flag (tables 1, 3, and 4)

In 2021, 82% of the 200 vessels involved in shipping accidents reported to the TSB were Canadian-flag vessels. Of these Canadian-flag vessels, 53% were commercial non-fishing vessels and 32% were fishing vessels; the remaining 15% were non-commercial vessels, pleasure craft or service vessels.

According to information provided by Transport Canada^{Footnote 3}, marine activity for Canadian commercial non-fishing vessels over 15 gross tons (GT) (excluding passenger vessels and cruise ships) was 12 309 thousand commercial vessel-km in 2021, which is 7% above the 2015–2020 average.^{Footnote 4} This yields a rate of 3.0 shipping accidents per million commercial vessel-km in 2021, lower than the prior 6-year average of 4.8. (Note that a 7-year series is too short to test for trends.)

Image

Using historical data (2011 – 2020) from the Department of Fisheries and Oceans (DFO) ^{Footnote 5}, the TSB  estimated there were 11 744 active fishing vessels in Canada in 2021 ^{Footnote 6}. The shipping accident rate for Canadian-flag fishing vessels (Figure 7) was 3.7 shipping accidents per 1000 active fishing vessels in 2021, below the rate of 6.2 in 2020, and below the 2011–2020 average of 5.9.

Image

For Canadian-flag fishing vessels, the most frequently reported shipping accident types in 2021 were fire/explosions (35%), groundings (30%), sinkings (12%), and collisions (9%). Canadian-flag commercial non-fishing vessels were most often involved in collisions (47%), groundings (19%), or fire/explosions (18%).

In 2021, 36 foreign-flag vessels were involved in shipping accidents in Canadian waters, 33 of which were commercial non-fishing vessels. According to information provided by Transport Canada,^{Footnote 7} marine activity for foreign commercial non-fishing vessels over 15 GT was 15 597 thousand commercial vessel-km in 2021, above the 2015–2020 average of 15 328 thousand commercial vessel-km. This yields an accident rate of 2.3 shipping accidents involving commercial foreign-flag vessels over 15 GT per million commercial vessel-km, above the 2015–2020 average.

Vessels lost (tables 1 and 5)

In 2021, 15 vessels were reported lost, up from 13 in 2020 but down from the 2011–2020 average of 18. Ten of the 15 vessels lost in 2021 were fishing vessels. Nine of the 15 vessels lost were less than 15 GT (including 4 with unknown tonnage). In the past 10 years (2012 to 2021), fishing vessels under 60 GT have accounted for 62% of Canadian vessels lost (tables 1 and 5, some data not shown).

Incidents

Overview of incidents

In 2021, 855 marine incidents were reported to the TSB, down from the total of 925 in 2020, but above the annual 10-year (2011–2020) average of 712.^{Footnote 8} Incidents in the Atlantic region (352) represented 41% of all marine incidents, followed by 29% (251) in the Pacific region, and 28% (243) in the Central region. The remaining 1% (9) of reported incidents occurred in foreign waters (Table 2).

The majority (85%) of reportable incidents involved the total failure of any machinery or technical system (Figure 8).^{Footnote 9} The largest proportion of these incidents (44%) occurred in the Atlantic region, while the greatest proportion of incidents involving risk of collision (51%) occurred in the Central region (data not shown). The types of vessel most often involved in total failure of any machinery or technical systems incidents in 2021 were fishing vessels (55%) and solid cargo vessels (23%) (data not shown).
