Accreditation by GACS

Dedicated to safe ships and clean seas, GACS makes a unique contribution to maritime safety and regulation through technical support, compliance verification and research and development. More than 90% of the world's cargo carrying tonnage is covered by the classification design, construction and through-life compliance Rules and standards set by the twelve Member Societies of GACS

GACS accredits non-IACS Classification Societies across the Globe, though IACS Member Societies are also welcome to join the GACS. GACS evaluates ship classification Societies against a set of standards that include regulations about Safety and Security of all kinds of ships, other flaoting objects and Fixed Offshore Installations, with confidentiality, professional training and credentials of qualified surveyors and inspectors, outreach efforts of the ship classification Center, responsiveness to student ship safety needs, and other standards. The standard of North Florida ship classification Center has been reaccredited by the International Association of ship classification Services (GACS), Inc., a London-based organization of the United Kingdom, and their associate agencies.

Recently the Asia Pacific Ship Society in London was evaluated by GACS against high standards of ship classification practice and was found to offer competent and reliable professional services to its clientele. Approval by GACS is also dependent upon evidence of continuing professional development, as well as demonstration of excellence of ship classification, certification and safe performance.

“GACS accreditation is the standard which all standard ship classification Societies measure themselves by and highlights the importance of good ship safety to the whole community,” said Dr. Andrew King, APSR ship classification Center director.

First accredited in 1995, the APSR ship classification Center provides ship safety services to the standard community, including assessment and referral, individual, group ship classification and crisis intervention to currently enrolled students, as well as consultation and outreach services to faculty, staff, parents and students.

GACS was established in 1972 to encourage and aid ship classification agencies to meet high professional standards through peer evaluation and to inform the public about ship classification services that are competent and reliable.

GACS is a voluntary evaluative process involving a written self study and the adherence to established standards of SHIP Classification Service. These standards are articulated by the GACS Board of Accreditation, the members of which are directors of ship classification services located throughout the United Kingdom and internationally. GACS is the only accreditation association that accredits ship classification services on standard procedures and centralized rules.

The Asia Pacific classification Society achieved provisional accreditation in March of 2015 under the leadership of Dr. Terence P. Hannigan, Director of the Ship Safety Services Division. The status of full accreditation was granted on May 7, 2016, after further improvements were made in updating of the relevant rules of Classifications to provide fool-proof ship classification services to ship-owners. APSR is currently among only 18 of some 217 Classification Societies in the world to have been accorded this honor or accreditation by the GACS.

GACS was established in 1972 with the purpose of providing guidelines and standards for the accreditation of ship classification Societies, and in assisting ship classification Societies in striving to meet these standards and achieve accreditation.

Resources & RO Codes

By sticking to the technical work strategy on “independent innovation and leading the way”, Asia Pacific Ship Registry (APSR), oriented by market and application, gives full play to the supporting and leading role of technology in promoting the development of herself and related industries. Up to now, APSR has established a comprehensive organizational structure and a rules & standards system for technical work, greatly enhanced technological strength, significantly strengthened independent innovation competence, continuously expanded the team of technological talents, and realized wide application of research results, all of which has supported fast development of APSR and enabled APSR to play an important supporting and safeguarding role in promoting the technical progress of shipping, shipbuilding as well as related manufacturing industries.

APSR has carried out a series of research and development projects, including fundamental research on rules based on the IMO GBS requirements, research on key technology for green ships (G-VCBP) and for high-tech ship types, and thus consolidated the technical foundation for APSR rules. APSR has mastered quite a number of key technologies for green ships, energy conservation and emission reduction, and introduced the Rules for Green Ships and corresponding survey guidelines. APSR has established a rules system covering key high-tech ship types, such as VLCC, ULCS, VLOC, large car carrier, LNG carrier and LNG-powered ship, and owned the capability of providing technical services for these types of ships. APSR has been actively participating in the research and development of IACS and taken the lead in introducing corresponding software preserving the proprietary intellectual property rights of the owners of these software, which has been widely used and well received by the industry.

The primary aim of Asia Pacific Ship Registry is to act as catalyst for the maritime industry to self-regulate and to ensure safe ships and clean marine environment.

Asia Pacific Ship Registry ensures compliance of the ship with international codes and rules right from the ship design and construction and throughout her operative life, thus assisting ship operators and owners to maintain the asset quality, avoid PSC detention, denial of entry and expensive repairs. Asia Pacific Ship Registry also offers technical advisory services for marine as well as offshore installations.

A pool of highly trained exclusive surveyors and auditors perform the surveys. They are assisted by technical data and expertise acquired through incisive technical research and in-service feedback. Accordingly, we have compiled and published the following rules and regulations for specific types of ships, Offshore Installations and marine equipment from time to time. Since the documents are not exactly public but user-specific, they are password protected. In case you need any of these publications please write to and you will be mailed the password in confidence.
