CONTAINER LASHING

CONTAINER LASHING Container lashing is a critical safety procedure used on container vessels to secure cargo during sea transport. Proper lashing prevents shifting, tilting, or falling of containers caused by vessel movement, heavy weather, and rolling motions. The system is composed of different components designed to keep containers stable, aligned, and firmly locked in place throughout the voyage. Key components of container lashing include: ●Long Lashing Rods – Used for higher container tiers to provide extended reach and strong vertical and diagonal support. ●Short Lashing Rods – Applied on lower tiers where shorter connections are required for stability. ●Turnbuckles – Adjustable tensioning devices that tighten lashing rods to maintain proper securing force.

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.

The Four Pillars of the International Maritime Organization (IMO)

The International Maritime Organization (IMO) establishes global standards to promote safety, protect the marine environment, ensure proper training of seafarers, and safeguard their welfare. These standards are anchored on four key conventions known as the 4 Pillars of IMO: 1. SOLAS – Safety of Life at Sea (1974) SOLAS is considered the most important international treaty concerning maritime safety. It sets the minimum standards for the construction, equipment, and operation of ships to ensure they are safe for both crew and passengers. This includes: • Fire protection systems • Life-saving appliances • Navigation and communication requirements • Emergency preparedness Its ultimate purpose is to prevent loss of lives at sea. 2. MARPOL – Marine Pollution (1973/1978) MARPOL addresses the prevention of pollution from ships. It regulates: • Oil and chemical spills • Sewage and garbage discharge • Air emissions from ships Its goal is to protect the marine and coastal environment by minimizing pollution from ship operations and accidents. 3. STCW – Standards of Training, Certification, and Watchkeeping for Seafarers (1978) STCW sets global training and competency standards for seafarers working on commercial vessels. It ensures: • Seafarers are properly trained, qualified, and certified • Uniform watchkeeping and operational safety practices across the world This helps maintain a high level of professionalism and safety at sea. 4. MLC – Maritime Labour Convention (2006) The MLC is often called the “Seafarers’ Bill of Rights.” It ensures that seafarers have: • Fair wages and employment contracts • Safe working and living conditions • Adequate rest hours • Medical care, social protection, and welfare The convention promotes human rights and dignity for those working at sea.

WILLIAMSON TURN

The Williamson Turn is a maneuver used to reverse the course of a vessel and return along its original track. It is primarily applied during Man Overboard (MOB) situations, especially when the exact position of the casualty is uncertain or when visibility is poor, such as at night or in fog. Purpose: • To bring the ship back onto its previous course line, improving the chance of relocating the person who fell overboard. • Ensures the vessel returns to the point of incident efficiently and safely. • Helps maintain visual and navigational reference in low-visibility conditions. Procedure: 1. Apply full rudder toward the side where the person fell overboard. 2. Allow the vessel to deviate 60° from its original course. 3. Shift full rudder to the opposite side. 4. Continue the turn until the vessel is heading about 20° from the reciprocal (opposite) course. 5. Return rudder to midships. 6. Steady the vessel on the reciprocal course and proceed back along the original track to search for and recover the casualty.
