Merchant Ship Categories....

  • Dry cargo ships:
               Until vessels started to be built to carry specific cargoes, all vessels were simply general or dry cargo vessels, i.e. built to carry any and all cargoes either in drums and bales or on pallets. Such cargoes were put in general holds with no specialization. The role of the general/dry cargo vessel began to wane with the arrival of bulk-carriers and tankers, but the decline of these general vessels has accelerated since the arrival of containerization (in the 1960's). Not only are container ships able to carry greater volumes of cargo in standard shaped cargo containers, the time spent loading and discharging has been dramatically reduced. Whereas a dry cargo vessel may take 3 - 4 days to load or discharge, a container ship can achieve the same in a matter of hours. Although general/ dry cargo vessels remain as the largest (in pure numbers) of cargo carrying vessels, they are often smaller (rarely above 50,000 Gross tons) than the specialized vessels that are slowly replacing them.
                  

  • Bulk Carriers:
              Bulkcarriers ("bulkers"), are the great work horses of the shipping world, carrying raw dry cargoes in huge cavernous holds, such as coal, iron ore, grain, sulphur, scrap metal. Until recently, there had been a huge demand for these vessels, driven by the extraordinary expansion of the Chinese economy. Imports of iron ore into China boosted the earnings of bulk carrier owners as freight rates went through the roof into uncharted territory. For a 'Capesize' bulkcarrier, daily hire rates of over $280,000 per day were recorded. Then came the downturn in late 2008 and freight rates have slumped, with bulkcarriers struggling to be fixed above $20,000 ! - quite a dramatic change in only a few months. Unfortunately, huge numbers of these vessels were ordered from shipyards during the 'boom' times. Taking about 2 years to build, many of these new ships will be delivered only to be sent probably straight to lay-up, as no work can be found for them.

                There are two types of bulkcarriers , one is that rare beast called a "Geared" bulkcarrier, because it carries it's own cargo cranes and another one is a more regular design of "Gearless" bulkcarrier.



                         Geared bulkcarriers                                                             Gearless bulkcarriers
                    Bulkers range from about 25,000 DWT ("handysize") through the medium size ("Panamax")vessels of about 75,000 DWT, to the giant ("capsize") vessels of up to 200,000 DWT (Some go bigger than that even !). Demand for the large "Capesize" bulkcarriers has never been higher, and there are a few "subdivisions" within this "Capesize" type, such as "Kamsarmax" (being the largest vessels able to enter the port of Kamsar, Equatorial Guinea, at about 175,000 DWT), "Newastlemax" (being the largest to be able to enter the port of Newcastle, Australia at about 185,000 DWT) and "Setouchmax" (being the largest able to navigate the Setouch Sea, Japan at about 203,000 DWT). With such high demand outstipping supply, some Very Large Crude Carriers are being converted to Very Large Ore Carriers (VLOC) and this is now a new size type for bulkcarriers over 200,000 DWT. Due to the heavy use that these vessels are put to, their life-expectancy is less than it would be for say, a container ship.



  • Tankers:

             A Tanker is a ship designed to transport liquid in bulk. Major types of tankers include the Oil tanker, the Chemical Tanker, and Gas carrier.

                                                     Oil Tanker

Chemical Tanker

LNG Carrier

             
An oil tanker, also known as a petroleum tanker, is a merchant shipdesigned for the bulk transport of oil. There are two basic types of oil tankers: the crude tanker and the product tanker. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move petrochemicals from refineries to points near consuming markets.
             Tankers are designed to carry liquid cargoes (not just oil) although the carriage of crude oil has brought the tanker unwelcome attention and largely unjustified criticism. Oil tankers come in two basic flavours, the crude carrier, which carries crude oil, and the clean products tanker, which carries the refined products, such as petrol, gasolene, aviation fuel, kerosene and paraffin. Tankers range in all sizes, from the small bunkering tanker (used for refuelling larger vessels) of 1000 DWT tons to the real giants: the VLCC (Very Large Crude Carrier) of between 2-300,000 DWT and the ULCC (Ultra Large Crude Carrier) of over 300,000 DWT.

Types of tankers:
  1. Handysize Tanker: 20,000-30,000 DWT.
  2. Handymax Tanker : Approx. 45,000 DWT.
  3. Panamax Tanker: Approx. 79,000 DWT.
  4. Aframax Tanker: Between 79,000-1,20,000 DWT.
  5. Suezmax Tanker: Between 1,20,000-1,80,000 DWT.
  6. V.L.C.C. Tanker: Between 2,00,000-3,00,000 DWT.
  7. U.L.C.C. Tanker: Over 3,00,000 DWT.
            It should be remembered that over 60% of the world's oil is transported by these tankers, and over 99% of that arrives safely without causing pollution. Indeed most oil pollution seen on beaches comes from the engine rooms of vessels (of all types) and not from the cargo tanks of tankers.


Crew Members on Ships....

2) ENGINE SIDE CREW MEMBERS:

  • Chief Engineer
  • Second Engineer/first assistant engineer
  • Third Engineer/ Second assistant engineer
  • Fourth Engineer/ Third assistant Engineer
  • Engine Cadet
  • Oiler
  • Wiper
  • Fitter
  • Motorman
  • Machinist
                                                                                                                           

Chief Engineer:
            
             A chief engineer (commonly referred to as "The Chief" or just "Chief") is responsible for all operations and maintenance that has to do with any and all engineering equipment throughout the entire ship.
            Under many jurisdictions the Chief Engineer is of equal rank to the Captain, with responsibility being split between the two posts; the Chief Engineer taking responsibility for engine room and maintenance and the Captain taking responsibility for navigation and deck operations.
            The chief engineer also determines the fuel, lube oil, and other consumables required for a voyage. The chief engineer also compiles an inventory for spare parts, oversees fuel, lube, and slop oil transfers, all major maintenance, prepares the engine room for inspection by local marine/safety authorities and and is in charge of the engine room during emergency situations.
            Sailing as chief engineer is an immense undertaking of great responsibility.

Second Engineer/first assistant engineer:
                  
            first assistant engineer(also called the second engineer in some countries) is a licensed member of the engineering department on a merchant vessel. This title is used for the person on a ship responsible for supervising the daily maintenance and operation of the engine department. They report directly to the chief engineer.
            On a merchant vessel, depending on term usage, "The First" or "The Second" is the marine engineer second in command of the engine department after the ship's chief engineer. Due to the supervisory role this engineer plays, in addition to being responsible for the refrigeration systems, main engines (steam/gas turbinediesel), and any other equipment not assigned to the Second assistant engineer/third engineer or the Third assistant engineer/fourth engineer(s), he is typically the busiest engineer aboard the ship.
            The first assistant/second engineer is usually in charge of preparing the engine room for arrival, departure, or standby and oversees major overhauls on critical equipment.

Third Engineer/ Second assistant engineer:
               
            Second Assistant Engineer or Third Engineer is a licensed member of the engineering department on a merchant vessel.
            The Second Assistant is usually in charge of boilers, fuel, auxiliary engines, condensate and feed systems, and is the third most senior marine engineer on board. Depending on usage, "The Second" or "The Third" is also typically in charge of fueling (a.k.a. bunkering), granted the officer holds a valid Person In Charge (PIC) endorsement for fuel transfer operations.
             He exact duties of this position will often depend upon the type of ship and arrangement of the engine department. On ships with steam propulsion plants The Second/Third is in charge of the boilers, combustion control, soot blowers, condensate and feed equipment, feed pumps, fuel, and condensers. On diesel and gas turbine propulsion plants The Second is in charge of auxiliary boilers, auxiliary engines, incinerator, air compressors, fuel, and fuel oil purifiers.

Fourth Engineer/ Third assistant Engineer:
               
             The Third Assistant Engineer, also known as the Fourth Engineer, is a licensed member of the engineering department on a merchant vessel.
            Generally the most junior marine engineer of the ship, this person is usually responsible for electrical, sewage treatment (resulting in the pejorative pun "turd engineer"), lube oil, bilge, and oily water separation systems. Depending on usage, they are called "The Third" or "The Fourth" and usually stands a watch and sometimes assists the third mate in maintaining proper operation of the life boats.
            With experience and additional training, third officers may qualify for higher rank.

Engine Cadet:
               The engine cadet closely follows the instructions of the First Engineer and attends the engine control room usually as part of the First Engineer's watch. The Engine Cadet assists in the maintenance and repair of engine room equipment, as well as other mechanical equipment throughout the ship. As part of the training process duties that are customary to the engine department will be assigned to the Engine Cadet by the Chief Engineer. Although on training the professional performance of the Engine Cadet will be evaluated for continued long-term career with the cruise line. Upon attainment of a National License and completion of at least one assignment aboard a cruise ship the most qualified candidates with the best performance evaluations could be promoted to Third Engineer position depending on current openings in the company's fleet.

Oiler:
             Oiler is an engine department rating position. The job of an Oiler onboard is to assist ship engineers lubricating bearings and other moving parts of engines and other mechanical equipment aboard the ship. The oiler participates in the general maintenance of ship's main power plant, auxiliary engines and generators in order to ensure that oil temperature is 
within the standard limits and oil gauges are all working properly.

Wiper:
              The engine utility man / wiper is an entry level rating position within the engine department of the cruise ship. The engine utility man / wiper provides general assistance to licensed engineers and superior engine room ratings in different tasks in the engine room, such as general maintenance and repair of the various machinery and equipment, material handling equipment throughout the ship including elevators and winches, general cleaning and painting of the engine room, trash pick up, tools and instruments pick up and cleaning.

Fitter:
              Responsible for the maintenance and repair of all Fitting.

Motorman:
              Responsible for the daily maintenance and cleaning of specific engine parts as directed by the Chief Engineer.
  
Machinist:
             machinist is a person who uses machine tools to make or modify parts, primarily metal parts, a process known as machining. This is accomplished by using machine tools to cut away excess material much as a woodcarver cuts away excess wood to produce his work. In addition to metal, the parts may be made of many other kinds of materials, such as plastic or wood products. The goal of these cutting operations is to produce a part that conforms to a set of specifications, or tolerances, usually in the form of engineering drawings commonly known as blueprints. 

Crew Members on Ships....


Crew members on ships-

1) DECK SIDE CREW MEMBER-
  • Captain/Master
  • Chief Officer/ Chief Mate
  • Second Officer/ Second Mate
  • Third officer/third mate
  • Deck Cadet
  • Bosun/ Boatswain
  • ABLE BODIED SEAMAN (AB)
  • ORDINARY SEAMAN (OS)
                                                                                                                                
  • Captain/ Master:

           The captain or master is the ship's highest responsible officer, acting on behalf of the ship's owner. The caption is a licensed mariner in ultimate command of the vessel.
           The captain is legally responsible for the day-to-day affairs of the ship as he is in command. It is his responsibility to ensure that all the departments under him perform legally to the requirements of the ship's owner. The Captain represents the owner and hence is called "Master".
           A Ship's Captain, also called Shipmaster or Skipper, is responsible for its safe and efficient operation, including cargo operations, navigation, crew management and ensuring that the vessel complies with local and international laws, as well as company and flag state policies. The Captain is responsible for responding to and reporting in case of accidents and incidents, and in case of injuries and illness among the ship's crew and passengers.
           If the master of the ship is incapacitated or absent from the vessel, the “CHIEF OFFICER” is in charge of all the operations as he is the executive officer of the ship.

Chief Officer/ Chief Mate:

           The chief officer/first mate (often called the chief mate in the United States) is the head of the deck department on a merchant vessel, second-in-command after the ship's master. The chief mate's primary responsibilities are the vessel's cargo operations, its stability, and supervising the deck crew. The mate is responsible for the safety and security of the ship, as well as the welfare of the crew on board.
            The chief mate typically stands the 4-8 navigation watch. Additional duties include maintenance of the ship's hull, cargo gears, accommodations, the life saving appliances and the firefighting appliances. The Chief Mate also trains the crew and cadets on various aspects like safety, firefighting, search and rescue, and various other contingencies.
The chief officer assumes command of the whole ship in the absence or incapacitation of the master. In port and at sea, the chief mate is responsible to the captain for keeping the ship, crew, and cargo safe for eight hours each day. Traditionally, the chief mate stands a "4-8" watch: from 4am until 8am and 4pm until 8pm.
             The Chief Mate is generally responsible for the stability of the ship.
IMO regulations require the officer be fluent in English. This is required for a number of reasons, such as ability to use charts and nautical publications, to understand weather and safety messages, communicate with other ships and coast stations, and to be able to work with a multi-lingual crew.

Second Officer/ Second Mate:

             A second mate (2/M) or second officer is a licensed member of the deck department of a merchant ship. The second mate is the third in command and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the tank-cleaning operations.
             In port and at sea, the second mate is responsible to the captain for keeping the ship, its crew, and its cargo safe for eight hours each day.
             Traditionally, the second mate stands a "12-4" watch: from midnight until 4am and noon until 4pm.

Third officer/third mate:
            A Third Mate (3/M) or Third Officer is a licensed member of the deck department of a merchant ship. The third mate is a watchstander and customarily the ship's safety officer. Other duties vary depending on the type of ship, its crewing, and other factors.
Duties related to the role of safety officer focus on responsibility for items such as firefighting equipment, lifeboats, and various other emergency systems.
            In port and at sea, the third mate is responsible to the captain for keeping the ship, its crew, and its cargo safe for eight hours each day. Traditionally, the third mate stands an "8-12" watch: from 8am until 12 noon and 8pm until midnight.

Deck Cadet:

            A Deck cadet is an officer under training in much the same way as in a military context. Cadets receive training in firefighting, first aid and survival techniques. Deck Cadets train in the fields of navigation, ship handling and cargo handling as well as maritime law. A cadet reports to the Chief Officer. His or her role as a trainee is to observe and learn, while helping out where possible, mostly the Chief Officer. As they do not have Certificate of Competency, cadets cannot hold a watch, but will likely assist one of the qualified officers, often with the Chief Officer, with their watch.

Bosun/ Boatswain:

            A bosun is an unlicensed member of the deck department of a merchant ship. The boatswain supervises the other unlicensed members of the ship's deck department, and typically is not a watchstander.
            The bosun works in a ship's deck department as the foreman of the unlicensed deck crew.  A bosun must be highly skilled in all matters of seamanship required for working on deck of a seagoing vessel. The bosun is distinguished from other able seamen by the supervisory roles: planning, scheduling, and assigning work.
            A bosun will have knowledge of and ability to use knots, hitches, bends, whipping, and splices as needed to perform tasks such as mooring a vessel. Competencies extend to the safe operation of a windlass. Duties may require operating the basic functions of a windlass, including letting go and heaving up an anchor. Moreover, a bosun may be called upon to lead firefighting efforts or other emergency procedures encountered in the inherently dangerous environment of a ship.

ABLE BODIED SEAMAN (AB):

           
An Able Seaman (AB) is an unlicensed member of the deck department of a merchant ship. An AB may work as a watchstander, a day worker, or a combination of these roles.
            At sea an AB watchstander's  duties include standing watch as helmsman and lookout. A helmsman is required to maintain a steady course, properly execute all rudder orders and communicate utilizing navigational terms relating to heading and steering. A watchstander may be called upon to stand security-related watches, such as a gangway watch or anchor watch while the ship is not underway.

ORDINARY SEAMAN (OS):

            An Ordinary Seaman (OS) is an unlicensed member of the deck department of a merchant ship. The position is an apprenticeship to become an Able Seaman, and has been for centuries. In modern times, an OS is required to work on a ship for a specific amount of time, gaining what is referred to as "sea time." Once a sufficient amount of sea time is acquired, the OS can apply to take a series of courses, and then a series of examinations to become certified as an able seaman.
            An OS is generally not required to stand watch, but must pass examinations on watchstanding skills such as performing lookout duty and being a helmsman. Thus an OS will often be found on a ship's bridge after working hours taking a turn at the ship's wheel or being familiarized with bridge equipment.
