DNV GL ADDITIONAL RULES AND GUIDELINES VI-11-3 PDF

++Before being commissioned, each vessel classified by Germanischer Lloyd (GL) has to undergo sea trials in the presence of a competent Surveyor of GL. Main objective of this guideline is to give all parties involved, like ship owners, shipyards, design offices and their subcontractors an overview of the scope of trials/ measurements in order to fulfil the sea trials requirements of GL and the SOLAS-Convention.

Besides the GL Rules for Classification and Construction and the relevant SOLAS-Convention requirements further national and international rules, regulations, technical standards and relevant recommendations from competent bodies have been taken into consideration.

The structure of these guidelines is based on typical, up-to-date trial programs for motor ships performed by major shipyards and shipping companies.

The final scope of trials and measurements should be laid down in each case individually, considering the building contracts and the flag state requirements.

A sea trial program in written form with all required tests has to be issued by the shipyard. That sea trial program has to be submitted to GL-Head Office for perusal and handed over to the GLSurveyor in charge.

The sea trial report, issued by the shipyard and signed by the GL-Surveyor in charge and the owner’s representative, has to be submitted to GLHead Office for review.
