International Ship and Port Facility Security (ISPS) Code

The International Ship and Port Facility Security (ISPS) Code is a global maritime security framework developed by the International Maritime Organization (IMO) to enhance the safety of ships and port facilities. It was introduced in response to growing concerns over terrorism, piracy, and unlawful acts against the maritime sector, particularly after the September 11, 2001 attacks. The ISPS Code entered into force on 1 July 2004 under the Safety of Life at Sea (SOLAS) Convention, Chapter XI-2. The primary objective of the ISPS Code is to detect security threats and implement preventive measures involving ships, ports, and governments. It establishes clear roles and responsibilities for Contracting Governments, shipping companies, shipboard personnel, and port authorities. Key requirements include conducting security assessments, developing and maintaining approved security plans, and appointing designated security officers such as the Company Security Officer (CSO), Ship Security Officer (SSO), and Port Facility Security Officer (PFSO). The ISPS Code operates under three security levels. Security Level 1 is the normal level, where minimum appropriate protective measures are maintained at all times. This includes routine access control, monitoring of restricted areas, and regular security patrols. Security Level 2 is applied when there is a heightened risk of a security incident. At this level, additional protective measures are implemented, such as increased patrols, stricter access controls, limited visitors, and closer monitoring of cargo and ship’s stores. Security Level 3 represents an exceptional level, activated when a security incident is probable or imminent. At this stage, specific protective actions are taken for a limited period, which may include suspension of operations, evacuation procedures, or direct coordination with authorities to protect the ship, port facility, and personnel.

Duties of an Electro-Technical Officer (ETO)

Duties of an Electro-Technical Officer (ETO) An Electro-Technical Officer (ETO) plays a critical role in ensuring the safe and efficient operation of a vessel’s electrical, electronic, and automation systems. As a key member of the engine department, the ETO is responsible for maintaining essential equipment that supports navigation, cargo operations, safety systems, and onboard living conditions. The ETO is in charge of the ship’s electric motors and power distribution systems, ensuring that machinery operates reliably at all times. This includes the maintenance and monitoring of the main and emergency switchboards, which are vital for uninterrupted electrical supply during both normal operations and emergency situations.

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.

PILOT LADDER RIGGING (For Access Height ≤ 9 meters)

A pilot ladder is a critical piece of equipment used for the safe embarkation and disembarkation of marine pilots. Proper rigging ensures compliance with SOLAS regulations and promotes safe transfer operations between the vessel and the pilot boat. Below are the components and their corresponding descriptions: 1. Handhold Stanchions Vertical supports installed at the ship’s deck edge to provide a secure handhold for pilots when stepping from the ladder onto the deck. They must be rigid, properly secured, and positioned to allow safe and unobstructed access. 2. Pilot Ladder The rope ladder used by marine pilots to board or disembark a vessel. It consists of wooden steps secured between two side ropes. The ladder must be in good condition, free from damage, and rigged in accordance with safety regulations. 3. Man Ropes Two ropes positioned on each side of the pilot ladder to provide additional support while climbing. Man ropes must be properly secured to strong points on deck and should not interfere with the ladder’s proper positioning. The vertical ropes forming the main structure of the ladder. These ropes support the steps and must have a minimum diameter of 20 mm to ensure sufficient strength and durability. 5. Steps Flat wooden steps secured to the side ropes. All steps must be horizontal, evenly spaced, and fitted to prevent rotation. Steps should be slip-resistant and free from cracks, splits, or deterioration.
