Regulations and Industrial Standards



The International Civil Aviation Organization (ICAO) is a UN specialised agency, created in 1944 upon the signing of the Convention on International Civil Aviation (Chicago Convention). ICAO works with the Convention’s 191 Signatory States and global industry and aviation organizations to develop international Standards and Recommended Practices (SARPs) which are then used by States when they develop their legally-binding national civil aviation regulations. There are currently over 10,000 SARPs reflected in the 19.

Annexes to the Chicago Convention which ICAO oversees, and it is through these SARPs and ICAO’s complementary policy, auditing and capacity-building efforts that today’s global air transport network is able to operate over 100,000 daily flights, safely, efficiently and securely in every region of the world.



The CAA is the UK’s independent specialist aviation regulator. The CAA publishes the CAP 437. The CAP

437 is a publication which gives guidance on the criteria applied by the CAA in assessing the standards of helicopter offshore landing areas for worldwide use by helicopters registered in the United Kingdom. The 6th Edition has been extensively revised to incorporate valuable experience gained from CAA funded research projects conducted with the support of the UK offshore industry. It also brings together revised requirements harmonised amongst North Sea States as a result of initiatives taken by the GASR Helideck Working Group. This publication provides the criteria applied by the CAA in assessing the standards of offshore helicopter landing areas for worldwide use by helicopters registered in the United Kingdom. The 7th Edition has been revised to incorporate the full and final specification for the helideck lighting scheme comprising perimeter lights, lit Touchdown/Positioning Marking “Circle” and lit Heliport Identification “H” Marking. It also includes new ICAO Standards and Recommended Practices relating to offshore helidecks and shipboard heliports that are due to be adopted in March 2013. For the first time requirements were included in the 6th Edition for the design of winching area arrangements located on wind turbine platforms. With the benefit of lessons learned through various industry forums attended since 2008 these sections have been reviewed and updated to represent current best practice.



IALA is a non profit, international technical association. Established in 1957, it gathers together marine aids to navigation authorities, manufacturers, consultants, and, scientific and training institutes from all parts of the world and offers them the opportunity to exchange and compare their experiences and achievements. IALA encourages its members to work together in a common effort to harmonise aids to navigation worldwide and to ensure that the movements of vessels are safe, expeditious and cost effective while protecting

the environment.The work of the committees is aimed at developing common best practice standards through publication of IALA Recommendations and Guidelines. This work ensures that mariners have aids to navigation which will meet their needs both now and in the future. Thus IALA contributes to a reduction of marine accidents, increased safety of life and property at sea, as well as the protection of the marine

environment. IALA also encourages cooperation between nations to assist developing nations in establishing aids to navigation networks in accordance with the degree of risk for the waterway concerned.



IMO – the International Maritime Organization – is the United Nations specialised agency with responsibility for the safety and security of shipping and the prevention of marine pollution by ships. As a specialized agency of the United Nations, IMO is the global standard-setting authority for the safety, security and environmental performance of international shipping. Its main role is to create a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented. The world relies on a safe, secure and efficient international shipping industry – and this is provided by the regulatory framework developed and maintained by IMO. IMO measures cover all aspects of international shipping – including ship design, construction, equipment, manning, operation and disposal – to ensure that this vital sector for remains safe, environmentally sound, energy efficient and secure. Energy efficiency, new technology and innovation, maritime education and training, maritime security, maritime traffic management and the development of the maritime infrastructure: the development and implementation, through IMO, of global standards covering these and other issues will underpin IMO’s commitment to provide the institutional framework necessary for a Green and sustainable global maritime transportation system.



The responsibility of the classification society is to verify that marine vessels and offshore structures comply with Rules that the society has established for design, construction and periodic survey. The classification process includes: the development of standards, known as Rules; technical plan review and design analysis; surveys during construction; source inspection of materials, equipment and machinery; acceptance by the Classification Committee; subsequent periodic surveys for maintenance of class; survey of damage, repairs and modifications.


Offering Practical Solutions

ABS recognizes that the classification world is changing with more emphasis on complex structures, life cycle management, unified standards and safety equivalencies. At ABS, we are dedicated to providing leadership in the development of new technologies intended to improve the safety standards for the marine and offshore industries.
