The Ship Security Alert System (SSAS) is provided to a ship for the purpose of transmitting a security alert to the shore to indicate to a competent authority (typically the ship's flag State) that the security of the ship is under threat or has been compromised. [1] [2] [3] [4] In case of a security incident, that may include attempted or actual piracy, terrorism [5] , armed robbery and similar attacks, the ship's SSAS can be activated by the Master and responsible members of the crew to continuously send silent alerts to the flag State, as well as predefined recipients that include the ship's owner (company). [6] The SSAS therefore forms an integral part of the security system for almost all merchant ships. [1]
The SOLAS Convention (Chapter XI-2, Regulation 6) which enforces the International Ship and Port Facility Security (ISPS) Code on maritime security requires all ships over 500 GT to be equipped with an SSAS. [1] [3] [7] Only exception are non-passenger vessels of less than 500 GT constructed before 1 July 2004. [8]
Technically, the SSAS consists of a GPS receiver linked to a transmitter, a power supply, software and activation buttons. [9]
There must be at least two independent activation points on the ship, one on the navigation bridge and the other(s) in places immediately accessible by the crew. [10] This may include the engine room, master's cabin or the crew lounge. The locations of the SSAS activation points and relevant procedure for use must be detailed in the ship's security plan (also required by the ISPS Code). [11] The activation points must be so designed that they cannot be inadvertently activated. [3]
When the ship is under attack, the crew can activate the SSAS beacon by pressing a button which automatically sends a message, usually SMS or email, over satellite connection to predefined recipients such as the ship owner, fleet manager and flag state. An SSAS report contains the ship name, unique identification numbers like MMSI, IMO number and call sign, the date and time, the ship's current position, speed and course. No audible or visible alarm is generated while the SSAS report is being transmitted to prevent discovery of the report by the intruders. Equally an overt radio/phone acknowledgment of the alert is also not made incase it poses a threat to crew if they have been captured. [10] Once the SSAS button is pressed, the alert will be continuously transmitted to the recipients unless it is reset or deactivated. An SSAS beacon operates with similar principles to the aircraft transponder emergency code 7500. [12]
The alert receivers (the ship's flag State) are obliged to inform the national authorities of the coastal states where the ship is sailing, so that help from nearby coastal State security forces can be dispatched to the location of the ship. [10]
The International Maritime Organization is a specialised agency of the United Nations responsible for regulating maritime transport. The IMO was established following agreement at a UN conference held in Geneva in 1948 and the IMO came into existence ten years later, meeting for the first time on 17 March 1958. Headquartered in London, United Kingdom, the IMO, in 2024, has 176 Member States and three Associate Members.
Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment, and resources and to protect personnel and property from damage or harm. Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property.
An emergency position-indicating radiobeacon (EPIRB) is a type of emergency locator beacon for commercial and recreational boats, a portable, battery-powered radio transmitter used in emergencies to locate boaters in distress and in need of immediate rescue. In the event of an emergency, such as a ship sinking or medical emergency onboard, the transmitter is activated and begins transmitting a continuous 406 MHz distress radio signal, which is used by search-and-rescue teams to quickly locate the emergency and render aid. The signal is detected by satellites operated by an international consortium of rescue services, COSPAS-SARSAT, which can detect emergency beacons anywhere on Earth transmitting on the distress frequency of 406 MHz. The satellites calculate the position or utilize the GPS coordinates of the beacon and quickly passes the information to the appropriate local first responder organization, which performs the search and rescue. As Search and Rescue approach the search areas, they use Direction Finding (DF) equipment to locate the beacon using the 121.5 MHz homing signal, or in newer EPIRBs, the AIS location signal. The basic purpose of this system is to help rescuers find survivors within the so-called "golden day" during which the majority of survivors can usually be saved. The feature distinguishing a modern EPIRB, often called GPIRB, from other types of emergency beacon is that it contains a GPS receiver and broadcasts its position, usually accurate within 100 m (330 ft), to facilitate location. Previous emergency beacons without a GPS can only be localized to within 2 km (1.2 mi) by the COSPAS satellites and relied heavily upon the 121.5 MHz homing signal to pin-point the beacons location as they arrived on scene.
Seamanship is the art, competence, and knowledge of operating a ship, boat or other craft on water. The Oxford Dictionary states that seamanship is "The skill, techniques, or practice of handling a ship or boat at sea."
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance.
Diver communications are the methods used by divers to communicate with each other or with surface members of the dive team. In professional diving, diver communication is usually between a single working diver and the diving supervisor at the surface control point. This is considered important both for managing the diving work, and as a safety measure for monitoring the condition of the diver. The traditional method of communication was by line signals, but this has been superseded by voice communication, and line signals are now used in emergencies when voice communications have failed. Surface supplied divers often carry a closed circuit video camera on the helmet which allows the surface team to see what the diver is doing and to be involved in inspection tasks. This can also be used to transmit hand signals to the surface if voice communications fails. Underwater slates may be used to write text messages which can be shown to other divers, and there are some dive computers which allow a limited number of pre-programmed text messages to be sent through-water to other divers or surface personnel with compatible equipment.
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention.
Digital selective calling (DSC) is a standard for transmitting predefined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS).
The International Ship and Port Facility Security (ISPS) Code is an amendment to the Safety of Life at Sea (SOLAS) Convention (1974/1988) on Maritime security including minimum security arrangements for ships, ports and government agencies. Having come into force in 2004, it prescribes responsibilities to governments, shipping companies, shipboard personnel, and port/facility personnel to "detect security threats and take preventive measures against security incidents affecting ships or port facilities used in international trade."
The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty which sets out minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards.
Deadweight tonnage or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew.
The International Cospas-Sarsat Programme is a satellite-aided search and rescue (SAR) initiative. It is organized as a treaty-based, nonprofit, intergovernmental, humanitarian cooperative of 45 nations and agencies. It is dedicated to detecting and locating emergency locator radio beacons activated by persons, aircraft or vessels in distress, and forwarding this alert information to authorities that can take action for rescue. Member countries support the distribution of distress alerts using a constellation of around 65 satellites orbiting the Earth which carry transponders and signal processors capable of locating an emergency beacon anywhere on Earth transmitting on the Cospas-Sarsat frequency of 406 MHz.
A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board.
Maritime security is an umbrella term informed to classify issues in the maritime domain that are often related to national security, marine environment, economic development, and human security. This includes the world's oceans but also regional seas, territorial waters, rivers and ports, where seas act as a “stage for geopolitical power projection, interstate warfare or militarized disputes, as a source of specific threats such as piracy, or as a connector between states that enables various phenomena from colonialism to globalization”. The theoretical concept of maritime security has evolved from a narrow perspective of national naval power projection towards a buzzword that incorporates many interconnected sub-fields. The definition of the term maritime security varies and while no internationally agreed definition exists, the term has often been used to describe both existing, and new regional and international challenges to the maritime domain. The buzzword character enables international actors to discuss these new challenges without the need to define every potentially contested aspect of it. Maritime security is of increasing concern to the global shipping industry, where there are a wide range of security threats and challenges. Some of the practical issues clustered under the term of maritime security include crimes such as piracy, armed robbery at sea, trafficking of people and illicit goods, illegal fishing or marine pollution. War, warlike activity, maritime terrorism and interstate rivalry are also maritime security concerns.
In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. But instead of employing visible light, radio beacons transmit electromagnetic radiation in the radio wave band. They are used for direction-finding systems on ships, aircraft and vehicles.
The IMO number of the International Maritime Organization is a generic term covering two distinct meanings. The IMO ship identification number is a unique ship identifier; the IMO company and registered owner identification number is used to identify uniquely each company and/or registered owner managing ships of at least 100 gross tons (gt). The schemes are managed in parallel, but IMO company/owner numbers may also be obtained by managers of vessels not having IMO ship numbers. IMO numbers were introduced to improve maritime safety and reduce fraud and pollution, under the International Convention for the Safety of Life at Sea (SOLAS).
The Maritime Operations Centre is a Bermuda government agency to provide support for maritime operations. It is located in St. George's and operates under the Department of Marine and Port Services.
The Ship Security Reporting System (SSRS) is a counter piracy system that has been developed to combat the increasing instances of hijack and ransom on cargo ships predominantly occurring in the Gulf of Aden and around the Horn of Africa.
Semaphore is the use of an apparatus to create a visual signal transmitted over distance. A semaphore can be performed with devices including: fire, lights, flags, sunlight, and moving arms. Semaphores can be used for telegraphy when arranged in visually connected networks, or for traffic signalling such as in railway systems, or traffic lights in cities.
An emergency locator beacon is a radio beacon, a portable battery powered radio transmitter, used to locate airplanes, vessels, and persons in distress and in need of immediate rescue. Various types of emergency locator beacons are carried by aircraft, ships, vehicles, hikers and cross-country skiers. In case of an emergency, such as the aircraft crashing, the ship sinking, or a hiker becoming lost, the transmitter is deployed and begins to transmit a continuous radio signal, which is used by search and rescue teams to quickly find the emergency and render aid. The purpose of all emergency locator beacons is to help rescuers find survivors within the so-called "golden day", the first 24 hours following a traumatic event, during which the majority of survivors can usually be saved.
