The essential aspect of ship classification is the development of standards known as Class Rules. PRS develops, promulgates, updates and applies rules and technical standards for the design, construction and survey of ships and other marine-related structures. These Rules and Standards are established, developed and updated by the Technical Committee and pertains to the structural strength and integrity of the ship’s hull and reliability of propulsion system, powering, steering system, etc. and is administered and implemented by the Classification Committee through the Society’s Surveyors and technical staff for issuance/assignment of classification certificates and registration of vessels in the PRS Registry Book.
PRS Technical Division reviews and approves design plans of ships and offshore installations to verify compliance of the hull structure, stability, machinery, electrical and automated systems to the requirements of PRS Rules, national and international regulations as applicable.
We use the latest “Maxsurf Enterprise Suite” software of Bentley Systems, USA for this purpose.
New Building Surveys
PRS Surveyors attends at the shipyard from keel laying to delivery to verify that the approved plans are followed, good workmanship practices are applied and other applicable Rules are adhered to in all respects.
During the construction of a vessel, PRS surveyors witness at the place of the manufacture or fabrications the tests of materials for hull and certain items of machinery, as required by the Rules. They also survey the construction, installation and testing of structural members, mechanical and electrical systems. Throughout the time of construction, we maintain an on-going dialogue with the Shipowner and Shipbuilder to make sure the Rules are understood and adhered to and also to assist resolving differences that may arise to avoid costly delays.
When completed, a vessel undergoes sea trial attended by a PRS surveyor to verify that the vessel performs satisfactorily in accordance with the Rules.
PRS conducts periodic surveys to determine whether a vessel is being maintained in a condition worthy of maintaining classification status such as special, annual, intermediate and docking surveys.
When authorized by the Philippine government or any foreign flag state, PRS can provide statutory inspection services and issue corresponding certificates to vessels in order to comply with flag state requirements and IMO Conventions. We are authorized by the Philippine Coast Guard to survey and issue certificates under the International Convention for the Prevention of Pollution from Ships (MARPOL), amongst others.
