About the database

Number of vessels per type of vessel. year of exposure 2019


Since 1985, leading members of Cefor have compiled and analysed statistical information relevant to their hull and machinery insurance portfolio. Since the introduction of electronic reporting from the 1995 underwriting year, the number of vessels reported each year has increased substantially from 5,500 in 1995 to more than 19,000 in 2019. This includes both lead and non-lead business. By the end of 2019, the Nordic Marine Insurance Statistics (NoMIS) database comprised 284,570 vessel years and 71,482 claims for vessels with a registered IMO number for the years 1995 to 2019. Including small coastal vessels, the totals were 481,887 registered vessel years and 96,163 claims. 

Portfolio characteristics

Cefor members underwrite a wide range of tonnage. Due to the somewhat different characteristics of the ocean and coastal hull segment, Cefor issues separate statistics for international ocean-going vessels with an IMO number and for the Nordic coastal segment.

Comparing the NoMIS portfolio to the world fleet, Cefor members' coverage of the world fleet is highest for the largest and youngest vessels. In the segment for vessels above 10,000 gross tons, NoMIS members participate in about 50% of the 27,361 vessels in the world fleet (as of January 2020).

Cefor members also write a significant portfolio of Mobile Offshore Units. These are not included in the NoMIS database. The members participate in about half of the world fleet of Mobile Offshore Drilling units.


The ocean hull trends are based on vessels with a registered IMO number. The coastal hull trends are derived from vessels defined as fishing vessels and any other vessel up to 5,000 gross tons or 15 meters in length but excluding supply/offshore vessels, which are part of the ocean hull statistics.

100% shares

All figures are adjusted to 100% of the vessel to give as objective a picture of the claims trends as possible. The figures are thus independent of the share underwritten by one single insurer or the combined Nordic market share for the vessel.

Date of loss perspective (accident year)

Unless otherwise indicated, all claims graphs reflect the date-of-loss perspective, i.e. claims are grouped by the calendar year in which the loss occurred, also called accident year, as opposed to grouping claims by the underwriting year (the inception year of the insurance coverage). The date-of-loss perspective allows a more up-to-date picture of recent claims trends and a more exact estimation of the ultimate expected claims amount for the latest year.

IBNR adjustments thus represent only the expected adjustment of outstanding claims reserves for claims incurred by 31 December, and no additional reserves for claims that will first incur in 2020, but are attached to the 2019 underwriting year. 

Exchange rates

The figures in the NoMIS reports are converted to USD, with the exception of the coastal segment, which is presented in NOK to better reflect the true claims trends of this portfolio. Paid claims are converted into USD (NOK) at the exchange rate of the month of payment; outstanding claims reserves are converted with the exchange rate as of December 2019.
