PARTS OF A SHIP

Front (Bow) Area Bulbous Bow A rounded projection located below the waterline at the forward part of the hull. It reduces wave resistance and helps improve the ship’s fuel efficiency and stability. Bow The forward-most section of the ship designed to cut through the water as the vessel moves. Stem The vertical front edge of the bow that forms the main support where the two sides of the hull meet. Foredeck The deck area located at the forward part of the ship, often used for anchor handling and mooring operations. Fore Mast A mast positioned near the bow used to mount lights, radar, antennas, and other navigational instruments. Hatch Cover A watertight cover placed over cargo holds to protect the cargo from seawater and weather exposure. Deck The main working platform of the ship where crew activities and operations take place. Hull The main outer structure or body of the ship that provides buoyancy and keeps the vessel afloat. Anchor A heavy device lowered to the seabed to hold the ship in position and prevent drifting. Bridge The command center of the ship where navigation, control, and monitoring of vessel movement and operations are performed. Midship and Superstructure Superstructure The portion of the ship constructed above the main deck, housing key operational and living spaces. Accommodation The area where the crew lives and works. It includes cabins, mess rooms, offices, and other essential living facilities. Flying Bridge / Bridge Wings Side platforms extending from the bridge used for maneuvering and observation, especially during docking and unmooring. Monkey Island An open platform located above the bridge that provides access to radar, communication, and navigation equipment, as well as offering an unobstructed view of the surroundings. Main Mast The primary mast supporting communication systems, navigation lights, and other electronic devices.

MARPOL 73/78 CONVENTION: LATEST UPDATES

The International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978, more commonly referred to as MARPOL 73/78, is the primary international agreement developed by the International Maritime Organization to prevent pollution of the marine environment from ships. Adopted in response to growing concern over oil spills and vessel discharges in the 1970s, it has since evolved into a comprehensive framework that addresses multiple forms of ship-source pollution. Together with SOLAS, MARPOL is regarded as one of the twin pillars of international maritime law, protecting both human life and the natural environment. MARPOL applies to all ships, though its requirements vary depending on size, type, and operation. Compliance is ensured through certification by flag states, enforcement by port state control, and the application of special provisions for designated “special areas” and “emission control areas” where stricter rules apply. Over the years, the Convention has grown through six technical annexes, each dedicated to a specific category of pollution. These annexes are the foundation of MARPOL and remain central to its implementation. Annex I addresses the prevention of pollution by oil. It includes requirements for double-hulled oil tankers, oil discharge monitoring and control systems, oily water separators, and record books. It is one of the most detailed annexes, reflecting the seriousness of oil pollution incidents. Annex II concerns the control of pollution by noxious liquid substances carried in bulk. It establishes categories for chemicals, prewash procedures, and restrictions on discharges, requiring chemical tankers to operate under strict safety and environmental standards. Annex III regulates the prevention of pollution by harmful substances carried by sea in packaged form. It is closely linked to the International Maritime Dangerous Goods (IMDG) Code, ensuring labeling, packaging, and documentation are standardized. Annex IV covers the prevention of pollution by sewage from ships. It requires ships to install approved sewage treatment plants or holding systems and regulates discharges into the sea, particularly in designated sensitive areas. Annex V deals with the prevention of pollution by garbage from ships. It prohibits the discharge of plastics, restricts the disposal of other wastes, and requires vessels to maintain garbage management plans and record books. This annex has been strengthened repeatedly to reflect the global urgency of reducing marine litter. Annex VI addresses the prevention of air pollution from ships. It limits emissions of sulfur oxides (SOx) and nitrogen oxides (NOx), regulates fuel oil quality, prohibits ozone-depleting substances, and introduces greenhouse gas reduction measures such as the Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP), and the Carbon Intensity Indicator (CII). It also establishes Emission Control Areas where more stringent standards apply. Recent amendments highlight MARPOL’s responsiveness to modern environmental challenges. In 2024, Annex I was updated to require improved oil discharge monitoring equipment, while Annex II introduced expanded prewash obligations in the Baltic and North Sea to reduce chemical residues. Annex IV tightened sewage effluent standards, and Annex V expanded garbage management requirements to smaller ships and reinforced prohibitions on plastics. Annex VI amendments in 2024 introduced stricter nitrogen oxide limits for new engines and strengthened rules for ships using alternative fuels, ensuring adequate fire protection and fuel distribution systems in parallel with the IGF Code. By 2025, MARPOL continues to advance global decarbonization and environmental protection objectives. Annex VI now mandates enhanced monitoring and verification of the Carbon Intensity Indicator, requiring ships to achieve satisfactory efficiency ratings or adopt corrective action plans. This step places greater responsibility on shipping companies to reduce operational emissions. Electronic record books for oil, garbage, and cargo handling operations are increasingly being accepted in place of paper logs, reflecting the shift toward digital compliance and reducing administrative burdens. New reporting obligations for lost containers at sea, coordinated with parallel SOLAS amendments, will also apply from 2026, ensuring faster notification to authorities and minimizing environmental and navigational hazards. Annex III, through updates aligned with the IMDG Code, further enhances labeling and documentation for harmful substances in packaged form. These updates underline MARPOL’s role as a living instrument that evolves in response to both long-standing pollution risks and emerging challenges such as climate change, marine litter, and the transition to alternative fuels. The integration of greenhouse gas measures under Annex VI,

WHAT IS WINDLASS?

A windlass is a vital deck machinery system used on ships to hoist, lower, and control the anchor and its chain with precision and safety. Typically powered by either electric or hydraulic motors, the windlass relies on a gypsy or wildcat wheel, which is specially designed to fit the shape of chain links, ensuring a firm grip during operation. This setup allows the crew to manage heavy anchoring equipment efficiently, even in challenging sea conditions. Purpose • To lower or “let go” the anchor safely, ensuring it descends at a controlled speed • To heave up the anchor and its chain smoothly when departing or shifting position • To maintain proper control of tension and speed throughout anchoring operations, preventing damage to the equipment or sudden strain on the vessel Overall, the windlass plays a crucial role in securing a ship at anchor and ensuring safe, reliable maneuvering during critical anchoring procedures.

ENCLOSED SPACE ENTRY

Enclosed Space Entry refers to the controlled and authorized process of entering a space that is not designed for continuous occupancy, has limited means of entry or exit, and may contain hazardous atmospheres or conditions. Because of these risks, entry is only allowed after proper assessment, preparation, and permitting to ensure the safety of all personnel involved. ⸻ KEY REQUIREMENTS FOR ENCLOSED SPACE ENTRY 1. Equipment All required safety equipment must be prepared and inspected before entry. This includes rescue gear, communication devices, PPE, first-aid kits, and emergency response tools to ensure immediate action in case of an incident. 2. Ventilation Proper mechanical ventilation must be established to supply fresh air and remove toxic, flammable, or oxygen-deficient atmospheres inside the space. 3. Risk Assessment A thorough risk assessment must be completed to identify hazards such as toxic gases, low oxygen levels, heat stress, flooding, or mechanical risks before entry is permitted. 4. Linkman (Standby Person) A trained standby person must remain outside the enclosed space at all times to monitor the entrant, maintain communication, and initiate emergency procedures if required.
