Wavelength and frequency are two important terms used in wave motion, navigation systems, sound, light, and communication technology. These concepts are commonly studied in maritime education, especially in subjects related to physics, electronics, radar, and radio communication onboard ships. Wavelength refers to the distance between two identical points in a wave, such as crest to crest or trough to trough. It represents one complete cycle of the wave. In the illustration, the wavelength is shown as the horizontal distance covering one full wave pattern. Longer wavelengths usually mean the waves are spread farther apart, while shorter wavelengths indicate the waves are closer together. Frequency, on the other hand, refers to the number of wave cycles passing a certain point within one second. It is measured in Hertz (Hz). A wave with high frequency produces more cycles in a shorter period, while a low-frequency wave produces fewer cycles over the same time. Frequency and wavelength are closely connected because when frequency increases, wavelength usually decreases.
South Korean Probe Says Unidentified Projectiles Hit HMM Ship Near Persian Gulf
South Korean Probe Says Unidentified Projectiles Hit HMM Ship Near Persian Gulf South Korean authorities said their investigation found that two unidentified projectiles struck the cargo vessel HMM Namu during an incident near the Persian Gulf on May 4, causing a major fire onboard and serious damage to the ship. According to South Korea’s Ministry of Foreign Affairs, investigators reviewed CCTV footage, inspected the damaged areas of the vessel, and interviewed the captain and crew members. Officials said the evidence showed that two airborne objects hit the vessel about one minute apart while the ship was anchored near Umm Al Quwain in the United Arab Emirates.
Iran-Linked Attacks Raise Tension in Gulf Waters After Bulker Hit Near Qatar
Tension in Gulf waters continued to rise after a bulk carrier sailing near Qatar was reportedly struck by an unidentified projectile on Sunday, May 10, amid ongoing regional conflict involving Iran, the United States, and allied nations in the Middle East. According to the United Kingdom Maritime Trade Operations (UKMTO), the vessel reported being hit while transiting waters near the port of Mesaieed, Qatar. Initial information indicated that a small fire broke out onboard following the impact. The fire was later extinguished, and authorities confirmed that no crew members were injured during the incident. No pollution or environmental damage was also reported.
Iranian Shadow Fleet Tanker Catches Fire Near Jask, Raising New Maritime Security Concerns
Iranian Shadow Fleet Tanker Catches Fire Near Jask, Raising New Maritime Security Concerns A sanctioned Iranian-linked tanker operating as part of the so-called “shadow fleet” was reported on fire near Bandar-e Jask, Iran, adding more tension to the already sensitive situation in the region. According to satellite images reviewed by maritime analysts, the tanker identified as Sevda was seen emitting heavy smoke while still afloat around 11.5 nautical miles southeast of Jask. Reports said the fire appeared to come from the aft section or rear part of the vessel. The exact cause of the incident remains unclear as of writing.
Body Recovered from Capsized Cargo Vessel “Mariana” Finally Identified. 5 crew still missing
Body Recovered from Capsized Cargo Vessel “Mariana” Finally Identified. 5 crew still missing. The body recovered from the overturned cargo vessel Mariana has now been identified, while search operations continue for five other missing crew members following the tragic maritime incident near the Northern Mariana Islands. According to reports, the recovered victim was identified as crew member Chet Brochon after confirmation from the family and local authorities. Divers earlier retrieved the body from inside the capsized vessel during underwater operations conducted by rescue teams.
Cebu Maritime Expo 2026 Concludes with Strong Success, Showcasing Industry Unity and Growth

DMW Launches Reintegration Network and Job Fair for Repatriated OFWs
The Department of Migrant Workers (DMW), led by Hans Leo J. Cacdac, has launched the Bagong Pilipinas: Bayanihan para sa Balikbayang Manggagawa National Reintegration Network (NRN) and Job Fair to provide support for repatriated Overseas Filipino Workers (OFWs). The initiative serves as a one-stop platform offering various services to returning OFWs and their families, particularly those affected by the ongoing Middle East crisis. Around 800 returning workers are expected to benefit from the program, which focuses on helping them transition back into the local workforce and community.
ALMA Maritime Group Social Soire
The ALMA Maritime Group, together with host company Tsakos Maritime Philippines, recently held a collaborative dinner that brought together key stakeholders from both the private and government sectors. The event was held at SuperSam, creating a comfortable setting for open discussion and meaningful interaction within the maritime community.
MAJOR CIRCLES OF THE EARTH IN MARITIME NAVIGATION
The Earth is divided into several major circles that play an important role in maritime navigation, geography, climate study, and global positioning,. These imaginary lines help seafarers identify locations, understand weather conditions, and navigate safely across different oceans and seas around the world. The Equator, located at 0° latitude, is the main reference line that divides the Earth into the Northern Hemisphere and Southern Hemisphere. Areas near the Equator experience warmer temperatures and are commonly known as the Torrid Zone. In maritime operations, vessels crossing this region often encounter tropical weather systems, heavy rainfall, and high humidity.

Principle of Flotation The principle of flotation explains why ships, boats, and other floating structures are able to stay on the surface of water despite their massive size and weight. This principle is based on the concept that a floating body displaces a volume of liquid whose weight is equal to the weight of the body itself. In simple terms, when a ship is placed in water, it pushes aside or displaces a certain amount of water. The water then exerts an upward force on the ship known as upthrust or buoyant force. For a vessel to float, the upward force generated by the displaced water must be equal to the downward force caused by the ship’s weight. This creates a balanced condition where upthrust equals weight, allowing the ship to remain afloat without sinking or rising further. If the ship’s weight becomes greater than the buoyant force, the vessel will sink deeper until enough water is displaced to restore balance or in extreme cases, it may sink completely. A ship made of steel can float because of its hull design. Although steel is denser than water, the hollow structure of the ship contains air, increasing the vessel’s overall volume while distributing its weight over a larger area. This lowers its average density, making it less dense than the water it displaces.
A Bill of Lading (B/L) is one of the most important documents in shipping. It is issued by the carrier to the shipper as proof that goods have been received for transport. It serves as a receipt, a contract of carriage, and a document of title, allowing the holder to claim the cargo at the destination port. Common Types of Bill of Lading Straight B/L – Non-negotiable, goods go only to a named consignee Order B/L – Negotiable, can be transferred to another party Bearer B/L – Whoever holds it can claim the cargo
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.
