The Role of Marine inspection – Vessel vetting process
Marine operations and the offshore logistical functions were recognised as holding a critical role within this company’s offshore wind farm operations. It was already well understood that early intervention with proper and thorough vessel inspection assisted the identification of potential causes of incidents and allowed corrective and preventative measures to be applied at an early stage. Vessels operating in the offshore sector already received all certification and inspections required by classification societies and Flag states as well as various
other agencies and organisations. It was accepted that an overview of all these activities was necessary to assess that the appropriate standards continued to be met and achieved. This was also required by many insurers of these offshore ventures, quite often as part of the marine warranty process, to confirm that vessels continued to be operated safely and effectively.
This verification or “vetting” process is certainly not new and not a unique innovation of the wind sector. The process has been well developed in the oil and gas Industry mainly through IMCA (International Maritime Contractors Association). This process was completed using the standard inspection document Common Marine Inspection Document (CMID- IMCA M 149) which has evolved over a number of years and is now at Issue 10 released in July 2016. This latest version
has returned to the process of identifying specific vessel types in appendices and identifying the additional verifications required on that vessel type. This is a welcome development and can only enhance the quality of the IMCA inspection process long term. It was also recognized that there were a number of much smaller vessels or workboats as they are more commonly referred. The CMID inspection document was intended more for larger vessels and contains many requirements not needed by the smaller vessels. The provision of the Marine Inspection for Small Workboats (MISW – IMCA M189) document last issued in June 2016 at revision 3 was developed to address this very important area of offshore marine operations.
Within this company both inspection documents were generally completed but were not fully utilised; however, the
