This thesis follows the delivery and final stages of building process of a newbuilding vessel from a Finnish shipyard to a non-Finnish owner. The vessel is designed to operate on a congested short-sea transit line between two capital cities. The author was assigned to the shipyard to act as an inspector/surveyor on behalf of the shipowner to follow the shipbuilding to ensure the agreed quality and that all the regulations and requirements are followed as agreed on the shipbuilding contract and specification. To ensure the quality of works carried out, the author conducts technical inspections on fields of metal work and paintwork and other relevant fields that he is qualified for or needed. The author is also advising and/or inspecting on fields of fire protection, safety, documentation and vessel navigation equipment as well as supporting on other areas as interior construction quality and machinery spaces. In part of the author's duties at the shipyard is to prepare the shipboard documentation system (SMS), maintenance programs and development of emergency procedures by the time the vessel enters service. The author was assigned by the owner to be present at the shipyard until the completion of the vessel, after what he is considered to sail the vessel in rank of 2nd officer. The Thesis might help any other seagoing officer that might need to prepare a new or newly bought vessel to enter service and might give an insight at why shipbuilding tends to delay from the agreed schedules as well as provide an insight to the problems that might raise during the process.
