As the name suggests, the Common Marine Inspection Database (CMID) is an essential tool to have a standardized format for all reports made by inspectors inspecting offshore vessel. The governing authority for the CMID have been the International Marine Contractors Association (IMCA) which have been established in order to ensure that inspections are not repeated on marine vessels. The IMCA has recognized the international institute of Marine Surveying (IIMS) as an independent authority to assist in the implementation of the CMID process. Only IMCA approved IIMS inspectors are authorized to carry out CMID inspections. The CMID reports are completed and uploaded on the website using the E-CMID application available to Accredited Vessel inspectors (AVI’s) which is in a common format for standardization and ease of understanding. The CMID inspections applies to the offshore industry to promote safety and efficiency of the vessels in the fleet. All the offshore vessel have to undergo CMID inspections in order to be accepted by charterers. Prior to appointing an offshore support vessel, the charterer would like to get  details about the vessel being appointed by checking the old inspection report on the CMID database website. By considering the old inspection report they can decide before planning any further inspections. Once the
nomination for a CMID inspection is received from the charterer, close liaison is carried out by the AVI with the owners of the vessel. The CMID inspection should be undertaken only by the by an IMCA recognized competent inspector known as Accredited Vessel Inspector (AVI). We at Constellation Marine services have Accredited Vessel Inspector who are trained to carry out CMID inspections on behalf of IMCA. The International Institute of Marine Surveying (IIMS) is the verifying body who ensures that the inspectors are screened using a 2 step process in order to get  qualified as an accredited vessel Inspector (AVI).

Step 1: The concerned surveyor has to fill up a Common Marine Inspection Database (CMID) application highlighting their past experience and certification. This CMID application forms and relevant certifications along with various sample reports are then verified by a panel of experts of the surveying fraternity appointed by IIMS. There are 5 categories for which the applicant can be a

Step 2: The IIMS also carries out a 1 day CMID training for all AVI’s who have to clear the exam in order to become an accredited vessel’s Inspector.


The applications for CMID inspectors are sent to Maritime Surveying Authority of the International Institute of Marine Surveying (IIMS) who formulate and distributes the applications to the panel of various CMID accredited assessor who ensure that the inspector has sufficient qualification and experience to carry out effective CMID inspections for offshore support vessels. Sample reports of the previous surveying jobs done, preferably CMID inspections, have to be attached along with the applicant’s certification, resume and completion application form.

The AVI has to ensure that his accreditation is maintained valid by ensuring he carries out at least 2 CMID inspections per year and also completes his Continuous Professional Development (CPD) sheet and logbook provided by IMCA. Constellation Marine Services believes that performing CMID inspections for offshore vessel is a growing trend all over the world these days, with its importance already realized in the Far East countries such as Singapore and Malaysia. Making a standard format of reporting and easy access to all concerned is the way to go forward and surveyors at Constellation are already implementing it.
