Arrangements oF Combination Ladder for High Freeboard Vessels

A combination ladder arrangement for high freeboard vessels refers to the required setup that combines an accommodation ladder with a pilot ladder to ensure the safe transfer of marine pilots between a pilot boat and the ship. This arrangement is used when the vessel’s freeboard is too high for a pilot ladder alone to reach safely. In this setup, the accommodation ladder provides the main inclined walkway, while the pilot ladder is rigged at the lower end of the platform so the pilot can board and disembark at a safe height above the sea. International regulations prescribe several key requirements: • The pilot ladder must extend at least 2 meters above the lower platform. • The ladder must be secured to the ship’s side at a point 1.5 meters above the accommodation ladder platform. • The pilot ladder must offer a climbing height of 1.5 to 9 meters. • The lower platform must remain horizontal and positioned at least 5 meters above the water. • The accommodation ladder must maintain a maximum slope of 45 degrees.

Micrometer

What is a Micrometer A micrometer is a precision measuring instrument widely used in engineering, machining, ship maintenance, and industrial applications where accuracy is critical. It is designed to measure very small dimensions such as thickness, diameter, and length with high precision. Understanding the different parts of a micrometer helps users operate the tool correctly and achieve accurate measurements.

MULTIMETER

WHAT IS A MULTIMETER A multimeter is an essential diagnostic tool used in marine, electrical, and industrial environments to measure and troubleshoot electrical systems safely and accurately. This visual guide breaks down the key symbols, buttons, and sockets found on a digital multimeter, helping users quickly understand its functions and proper usage. The display section highlights important features such as AC/DC voltage readings, frequency, auto-ranging, hold, and min/max values, allowing precise monitoring of electrical parameters. Control buttons like Hold, Range, Function, and Brightness enhance ease of use, especially in low-light or onboard conditions.

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
