Emergency Position Indicating Radio Beacon (EPIRB), Through the use of satellites, is meant to help rescuers locate marine vessels in an emergency situation. These satellite-linked EPIRBs broadcast a unique, repeating distress signal that can be detected from virtually any point on earth. When properly registered, the signal includes a description of the vessel as well as its location. An activated EPIRB will send critical information via satellite that is routed directly to rescue units thereby reducing search time dramatically. See also MMSI.

International Association of Classification Societies (IACS) is an association of 11 classification societies. These Societies establish and apply technical requirements for the design, construction and survey of marine-related facilities, principally ships and offshore structures. These requirements are published as classification rules. Classification rules are developed to contribute to the structural strength and integrity of essential parts of the ship’s hull, and its appendages, and the reliability and the function of the propulsion and steering systems, power generation and those other features and auxiliary systems which have been built into the ship in order to maintain essential services on board for the purpose of safe operation of the ship. Classification surveys are carried out by qualified surveyors using mainly visual inspection and sampling techniques. Classification societies may also act as Recognised Organisations for Flag States, verifying the same vessel’s compliance with international and/or national statutory regulations.

The ISPS Code is given force through Chapter XI-2 of SOLAS. The Code has two parts, one mandatory and one recommended. In essence, the Code takes the approach that ensuring the security of ships and port facilities is a risk management activity and that, to determine what security measures are appropriate, an assessment of the risks must be made in each particular case. The purpose of the Code is to provide a standardised, consistent framework for evaluating risk, enabling governments to offset changes in threat with changes in vulnerability for ships and port facilities through determination and implementation of appropriate security levels and corresponding security measures.

The Organisation for Economic Co-operation and Development (OECD) is a forum where the governments of 30 market democracies work together to address the economic, social and governance challenges of globalisation as well as to exploit its opportunities. The Organisation provides a setting where governments can compare policy experiences, seek answers to common problems, and identify good practice andco-ordinate domestic and international policies. It is a forum where peer pressure can act as a powerful incentive to improve policy and implement “soft law” – non-binding instruments such as the OECD Corporate Governance Principle– and on occasion leads to formal agreements for treaties. The various exchanges among OECD governments come from information and analysis provided by a Secretariat that is located in Paris, France. The Secretariat collects data, monitors trends, and analyses and forecasts economic developments. It also researches social changes or evolving patterns in trade, environment, agriculture, technology, taxation and more.

Segregated Portfolio Company (SPC). Section 232 of the Companies Law (2004 Revision) enables a Company, as a single legal entity, to segregate assets and liabilities between segregated portfolios (SP) established within the Company. Although each segregated portfolio must be separately identified they are not separate legal entities apart from the Company. The Cayman Islands law provides that assets and liabilities of each portfolio are legally separate from those of another SP. Therefore, creditors of an SP have recourse to the assets of that particular SP, and to any general assets of the Company (being assets not belonging to any particular SP) exceeding the Company’s minimum capital requirements, if the assets of that particular SP are insufficient to meet the creditor’s claim.
