The Advisory System Ship's Safety MADRAS contains the supply of hardware and software appropriate to a ship, representing a novel type of conception for the safety of sea-going ships. This conception also includes the know-how of experts as the description of the respective current situation of the ship under the roof of an advisory system for a safe ship operation in dangerous situations.

MADRAS is developed according to:
- IMO Resolution A.741(18) ISM Code
- IMO Resolution A.796(19)
  "Recommendations on a Decision Support System for
   Masters on Passenger Ships"
- IMO Resolution A.852(20)
  "Guidelines for a Structure of an Integrated System of
   Contingency Planning for Shipboard Emergencies"

Step of actions exactly tailored to the respective emergency situation are elaborated for each advisory module and offered in catalogues of measures. These are not tranferable to each ship universally, but depend on the respective ship design and safety equipment. Succession and quality of these measures are aimed at the main objective of the advisory system - to bring under control and to overcome an emergency. All initiyted and terminated measures are recorded continuously and are available for follow-up analysis.
Configuration of advisory system, i.e. selection of modules, number and location of sensors can be adjusted to the wishes of the customer and the value of the object to be protected. Additionally, also further systems with safety character, starting with check lists, ship leaving passes and safety plans, typical for shipping companies, up to data base application of maintenance areas may be integrated in the advisory system.

Advisory Modules are available for the following classes of situations:
  • Fire
  • Flooding
  • Search & Rescue
  • Grounding
  • Resonance
  • Evacuation
  • SOPEP
  • Unlawful Act
Following please find short descriptions about some example modules. Please click the Thumbnails for enlargement.




Module Fire

The outbreak of a fire on board is one of the most frequent emergency situations at sea. Danger to persons, ship and environment multiply enormously in case of a great number of passengers and when transporting dangerious goods. Fast and - above all - a reliable fire detection is all the more important.
For the installation of the advisory system sensors could be integrated into loops already existing or have to be installed. By this change of sensor conception it is possible to ensure about an early fire detection and to obtain an assessment of the development of fire. Large areas may be monitored by installing gas sensors in suitable locations, such as exhaust and air condition ducts.
Especially with transport of dangerous goods and motor vehicles in ferry traffic there is the danger of flammable liquids flashing into steam, leaking and then possibly leading to cracking and even explosion. Therefore advisory module fire was also developed to detect this dangerous gas concentration quickly.

Characteristics:
  • supply of a catalogue of measures, related to the respective situation and locality of the ship, containing prpposals for important actions for mastering the emergency situation
  • extensive collection of assisting means backing up the respective measures
  • integrated record function for follow-up analysis
  • posibility to integrate additional sensors with indication of the analogue measuring value when exceeding of treshold value e.g. CO sensors to increase reliability of fire detection, thermocouples for monitoring temperature variation in case of fire, CO2 sensors for monitoring extinguishing gas concentration, measuring heads may be designed for different types of gases especially hydrocarbons
  • alarm is given to shipmaster and officers when a especially set level of the lower explosion limit is reached




Module Flooding

The analysis of sea accidentsof the last years shows, that with losses of ships due to flooding many people lost their lives.
The difficulty in case of flooding is the assessment of quantity of flooding water and the following stability calculation for the ship. This is demanded from the shipmaster and the officers in the case of emergency and it's very important for assessing the ship's situation. Evacuation initiated in time is often the decisive factor for the rescue of human lives.

Characteristics:
  • supply of catalogues of measures and record functions
  • calculation of quantity of flooding water and change of displacement, center of gravity and GM with flooding taking into consideration permeability factors
  • possibility to integrate water level sensors for giving alarm and determining the water height in special areas of the ship
  • determination of curve of static stability under changed criteria to assess the rest stability of the ship


Module Grounding

In the event of touching the ground and going fast aground an objective evaluation of the ship's situation takes priority since human lives are mostly not endangered directly.
A decision made too hastily about the procedure of the ship's coming off has in many cases even caused an increase of damage or a considerable increase in cost, respectively.
With the help of this advisory module the ship's management will be able through the input of current parameters such as draughts, loading and sounding sketch to determine the seating forces and bring-off forces. At the same time ir can be assessed whether outside assistance has to be requested or coming off is possibke by own means.

Characteristics:
  • supply of catalogues of measures and record functions
  • input of sea bed condition, trimm, draughts, tides and leakage water mass
  • input of a supposing sounding sketch
  • calculation of all grounding forces, lost buoyancy by leakage water and necessary force to come off
  • input of available forces to come off


Module Search & Rescue

Search for life-saving appliances and persons, that went over board can be a difficult task at sea. Success of search depends on the determination of the position of the scene of accidents as exactly as possible and on a search method adjusted to the situation, especially at darkness or in bad hydro-meteorological conditions.

Characteristics:
  • supply of catalogues of measures and record functions
  • selection of search method and type of life-saving equipment to be searched for
  • indication of ship's position and date of accident by integration of GPS data
  • representation of search algorythm with statement of position of route points to be headed for
  • possibility of integration of wind, current and visibility conditions
