JET CHISEL

A jet chisel (also called needle scaler) is a pneumatic tool made up of multiple thin steel rods (“needles”) that rapidly move back and forth when connected to compressed air. The vibration of the needles chips away rust, old paint, scale, and marine growth on metal surfaces. Think of it as “pangbaklas ng kalawang, pero industrial version.” Purpose: • Remove rust, corrosion, and scale from steel surfaces • Prepare metal before painting, welding, or coating • Clean areas where grinders and wire brushes can’t reach (corners, tight spots, edges) • Reduce manual scraping time and physical fatigue How to Use: 1. PPE First • Safety goggles / face shield • Ear protection (maingay ’yan) • Gloves • Mask (dust/rust particles) • Proper coverall 2. Check the Tool • Inspect air hose, connectors, and needles • Ensure air compressor pressure is within recommended range (usually 90 psi ± depending on tool) 3. Connect to Compressed Air • Attach hose firmly • Open the air valve gradually 4. Operate • Hold the tool with both hands • Press the needles gently against the surface — do not push too hard • Let the vibration do the work • Work in steady strokes 5. After Use • Shut off air supply • Clean and oil the needles to prevent rust • Store in dry location

IMMERSION SUIT: Essential Survival Gear for Every Seafarer

An immersion suit also called a survival suit is a life-saving garment designed to keep seafarers protected in the event of abandoning ship, especially in cold waters. Made of insulated, waterproof material, it drastically slows body heat loss and increases chances of rescue. Purpose • Thermal Protection: Retains body heat to prevent hypothermia. • Buoyancy: Keeps the wearer afloat without the need to swim. • Visibility: High-visibility color and reflective tape help rescuers locate survivors quickly. • Survivability: Protects against wind, waves, and freezing temperatures while awaiting rescue.

SOLAS CONVENTION: LATEST UPDATES

The International Convention for the Safety of Life at Sea (SOLAS) is recognized as the cornerstone of international maritime safety law. Originally adopted in 1914 following the tragic loss of the RMS Titanic, it has since been revised several times to keep pace with technological and operational advances in shipping. The 1974 SOLAS Convention, which came into force in 1980, introduced the “tacit acceptance” procedure, allowing amendments to automatically enter into force on a specified date unless objected to by a certain number of member states. This system ensures SOLAS remains a dynamic, living instrument capable of adapting quickly to new safety concerns. SOLAS establishes uniform minimum safety standards in the design, construction, equipment, and operation of merchant ships. All ships engaged in international voyages must comply, subject to inspections and certification by their flag state administrations, as well as verification by port state control officers when calling at foreign ports. The Convention also incorporates mandatory codes such as the ISM Code, ISPS Code, Polar Code, and HSC Code, ensuring comprehensive safety measures. The treaty has grown into a holistic framework addressing every aspect of ship safety, including fire prevention, life-saving appliances, safe navigation, carriage of cargoes, maritime security, and the safe management of shipping companies. Its reach extends from traditional merchant vessels to modern high-speed craft, bulk carriers, and ships operating in polar waters. The most updated structure of the SOLAS Convention includes the following chapters: Chapter I – General Provisions: Survey, certification, and enforcement. Chapter II-1 – Construction – Structure, Subdivision, and Stability, Machinery and Electrical Installations: Integrity of ship structure and machinery. Chapter II-2 – Fire Protection, Fire Detection, and Fire Extinction: Fire safety systems, training, and response. Chapter III – Life-Saving Appliances and Arrangements: Lifeboats, life rafts, survival suits, and muster arrangements. Chapter IV – Radiocommunications: GMDSS and distress alert systems. Chapter V – Safety of Navigation: Voyage planning, navigational warnings, and mandatory equipment like ECDIS and AIS. Chapter VI – Carriage of Cargoes: Loading, stowage, and securing of general cargoes. Chapter VII – Carriage of Dangerous Goods: IMDG Code compliance and hazardous cargo provisions. Chapter VIII – Nuclear Ships: Special safety arrangements for nuclear-powered ships. Chapter IX – Management for the Safe Operation of Ships (ISM Code): Safety management systems and company responsibility. Chapter X – Safety Measures for High-Speed Craft (HSC Code): Special rules for fast passenger and cargo craft. Chapter XI-1 – Special Measures to Enhance Maritime Safety: Continuous surveys, ship identification numbers, and inspection regimes. Chapter XI-2 – Special Measures to Enhance Maritime Security (ISPS Code): Ship and port facility security levels, drills, and plans. Chapter XII – Additional Safety Measures for Bulk Carriers: Structural reinforcements and safety precautions. Chapter XIII – Verification of Compliance: IMO audits of member states’ compliance. Chapter XIV – Safety Measures for Ships Operating in Polar Waters (Polar Code): Safety, environmental, and crew training standards in polar regions. Chapter XV – Safety Measures for Ships Carrying Industrial Personnel: Safe design and operation of vessels carrying offshore or industrial workers. Chapter XVI – Safety Measures for the Carriage of More than 12 Industrial Personnel on International Voyages: Latest addition, providing detailed regulations for industrial transport. In 2024, several significant amendments entered into force, further strengthening the safety framework. Updates to Chapter II-1 on construction and stability enhanced watertight integrity and introduced refined methods for damage stability calculations. These improvements, particularly in Parts B-1, B-2, and B-4, applied to new vessels and modernized long-standing requirements. Fire safety also received attention, with amendments to the Fire Safety Systems (FSS) Code easing requirements for individual detector isolators, balancing safety with practical shipboard application. Changes to the Life-Saving Appliances (LSA) Code clarified standards for launching appliances, including rescue boats and free-fall lifeboats, while providing exemptions from certain dynamic testing requirements. At the same time, the International Code of Safety for Ships using Gases or Other Low-flashpoint Fuels (IGF Code) was updated, reinforcing provisions on fire protection, fuel distribution, and fixed extinguishing arrangements. These changes ensured that ships using LNG and other alternative fuels maintained higher safety margins. Other 2024 amendments addressed mooring equipment, requiring de

EMERGENCY GENERATOR

Ship Emergency Generator: Essential Safety Power at Sea On board a ship, electricity powers almost every operation from navigation and communication systems to lighting, pumps, and emergency alarms. When the main power supply fails, the safety of the vessel, its crew, and cargo relies on a reliable backup source. This is where the ship’s emergency generator becomes indispensable. Mandated by the International Convention for the Safety of Life at Sea (SOLAS), the emergency generator is a critical piece of equipment designed to supply electrical power to essential systems during emergencies. Background and Purpose The emergency generator serves as the ship’s lifeline during power loss or blackout. It automatically starts and transfers load to an emergency switchboard to ensure that key systems remain operational. Its purpose is not to run the entire ship but to sustain safety and emergency functions until the main power supply can be restored or the ship is brought to safety. The generator powers essential equipment such as emergency lighting in accommodation spaces, machinery areas, lifeboat embarkation points, and escape routes. It also supplies energy to fire detection and alarm systems, communication equipment, navigation instruments like radar and GPS, and in some cases, the steering gear. Pumps for fire-fighting and bilge operations, as well as emergency batteries and chargers, also depend on this backup system. Location and Construction To maximize reliability, the emergency generator is installed in a separate compartment from the main engine room—typically on an upper deck with its own ventilation, fire protection, and access. This arrangement prevents the generator from being compromised by incidents in the engine room. Most are diesel-driven alternators chosen for their rapid start-up capability and rugged design. They have independent fuel tanks, cooling systems, and starting mechanisms to ensure operation even if the main systems fail.
