Communication System That Supports The GMDSS 06/08/2009
GMDSS stands for Global Maritime Distress and Safety System. It is a new system for automated and rapid response to a search and rescue. This system was mandatory for ship installation as of February 1, 1999. In order for this system to function as required by Solas chapter IV, we have to be familiar with the different system that supports the GMDSS. One system that is used by GMDSS is the Inmarsat Geostationary satellite. It is geostationary in the sense that its satellite is geosynchronous with the earth’s rotation and its satellites are situated along the equator and thus covers only up to 70 degrees North and South from the equator. This system is used by our Inmarsat terminals such as Inmarsat A/B, C, Mini-m, Inmarsat EPIRB, etc. Another support system is the COSPAS-SARSAT system. This system is used by our COSPAS-SARSAT EPIRB for global distress alerting. Unlike the Inmarsat Epirb where the coverage is limited, the Cospas-sarsat employs global coverage as its satellite is polar orbiting. Then lastly we have the Maritime Mobile Services on VHF, MF and HF bands for our Navtex, VHF/MF/HF DSC, Radiotelephony and Radiotelex.

 A Helmsman, sometimes called Wheelman or Steersman, must be able to execute and understand the steering orders given by the Conning Officer. A Conning officer can be the Master of the ship; the Officer on Duty; or the Pilot who gives the order to helmsman and control the ship’s navigation. In this sense, the helmsman must be able to understand and execute steering orders; take the manual steering immediately in high traffic density areas and in other circumstances needed; report to the officer any malfunctions on the steering system and be familiar with the steering system used which includes proper procedures in changing over from manual steering to autopilot to the non follow-up mode and vice versa; the ship’s rudder, steering and maneuvering characteristics of the vessel, etc. In my experience as a deck officer, I used to trick my helmsman by giving them sometimes a wheel command that is apparently endangers the vessel and I will see on how the he respond to it. But sad to say that 90% of them will just obey and execute the command without questioning the conning officer. A helmsman must question the order given by a conning officer if he thinks the command is not safe. Like for instance, the conning officer on a heavily loaded ship wishes to alter course hard to starboard. This will lead to a heavy list to starboard and the worst is it could capsize. A helmsman as well must report to the conning officer that the command has been understood before executing it and after it was executed. This will allow the officer to know if the order has been received correctly and executed properly. One of the key to a Safe Navigation is a great teamwork between the conning officer and the helmsman along with the look-out and other members of the bridge team.

The Global Maritime Distress and Safety System (GMDSS) were enforced by SOLAS and were mandatorily installed by ships as of February 1, 1999. With the introduction of this new system, the Morse code was phased out. Since the general concept of the GMDSS is to provide rapid and automated alerting for search and rescue during a distress incident, Solas made provisions (Solas Chapter IV) to govern this system particularly the 9 Communication Functional Requirements and shall be used by ships to the fullest of its capability. The nine communications and the means of communication method used are as follows: Free Downloadable PDF on Colreg 72 05/11/2009
Collisions can be avoided if every vessel abided by the International Rules for the Prevention of Collisions at Sea 1972, which came into force in 1977. It is therefore not surprising that collision accidents are increasing because these regulations were disregarded in differing areas. The most common contributory factors in all of the collisions were poor use of radar and poor lookout. The highlight of the need for the watch keepers on merchant vessels to keep an especially good lookout for and be knowledgeable of the rules contained in the COLREG. The collision regulations indicate that may is not the same as shall and there is a need to apply the COLREGS on every occasion. A free downloadable PDF on Colreg ‘72 is made available at the Colreg Section. This section was created to provide education and training resources to benefit the students and instructors in the Maritime Profession, especially the students of Capitol University particularly the College of Maritime Education and anyone interested in learning the International Regulations for Preventing Collisions at Sea, 1972. The Colreg PDF download is provided for free and is the own work of the webmaster, including the layout, the slide template, etc. These resources as well are available for free in PowerPoint format.

The focus of these Meteo PDF downloads is to gain insights on how the atmospheric pressure is distributed around the earth and its effect on the prevailing winds and ocean surface currents, as well as ship-borne meteorological instruments and their operation, various weather systems, reporting procedures and recording systems, the meteorological information, and the ocean currents and waves.Hence, the download section was established to provide education and training resources to benefit the students and instructors in the Maritime Profession, especially the students of Capitol University particularly the College of Maritime Education and anyone interested in learning the basics of Marine meteorology and oceanography. The PDF lecture download is converted from the PowerPoint format which is provided for free and is the own work of 2/M John Jaromahum, my co-instructor at Capitol University, College of Maritime Education. Proceed to the METEO Section >> These free downloadable lecture resources in Portable Document Format (PDF) was made available to provide education and training resources to benefit the students and instructors in the Maritime Profession, especially the students of Capitol University particularly the College of Maritime Education and anyone interested in learning the Deck Watch Keeping for Officers.

 To facilitate the learning and a more understandable interpretation of the lights and shapes specified by the International Regulations for Preventing Collisions at Sea, 1972 (COLREG ’72), Jojoeland.com has introduced a graphic interpretation of the lights and shapes to be displayed by ships in accordance of such convention. The graphic images are in 3D showing the lights and shapes displayed by a vessel in all aspect: dead ahead; dead astern; starboard side; and port side, as well as the night and daytime view of such display. The colreg section discusses about the rules of the road to prevent collision. It offers as well free downloadable PowerPoint presentation on the international regulation for preventing collisions at sea. Jojoeland.com is currently working on the PDF format of the downloadable COLREG presentation. Your comments and suggestions are very much welcome on how may I improve these resources.

In the maritime profession, marine meteorology is one of the essential fields of studies that a navigator must be knowledgeable and competent of. A navigator must be able to sail the ship safely to its destination regardless of bad weather and rough seas. To overcome this challenge, a navigator must act as a meteorologist on board and acquiring accurate weather forecast to facilitate a safe voyage. Predicting and forecasting weather is directly related to the availability of many kinds of data which large amounts of it can be analyzed. The advances of technology make it easier for navigators to obtain weather information. Navigators always record weather conditions and obtain weather forecasts to determine changes of weather and sea conditions. A barometer, a psychrometer, a thermometer and an anemometer readings are just some of the things navigators monitored and analyzed. Here is a free powerpoint on Meteorological Instruments.
