UNCLOS WATERS

The United Nations Convention on the Law of the Sea (UNCLOS) stands as one of the most important international agreements in maritime history, providing a comprehensive framework that governs the rights, responsibilities, and conduct of nations in their use of the world’s oceans. Adopted in 1982 in Montego Bay, Jamaica, and entered into force in 1994, UNCLOS has since become the “constitution of the oceans,” shaping the global maritime order and ensuring stability in international waters. Today, more than 160 countries, including the Philippines, are parties to this convention, making it one of the most widely recognized treaties in modern international law. At its core, UNCLOS defines the extent of maritime zones, granting coastal states sovereign rights and jurisdiction over certain areas of the seas while maintaining the principle of freedom of navigation. The convention establishes baseline measurements from which maritime zones are determined, ranging from internal waters, territorial seas, and contiguous zones, to exclusive economic zones (EEZs) and continental shelves. These zones outline the rights of coastal states to exploit resources, regulate activities, and protect their environment, while balancing the rights of other states to access international waters. The territorial sea, extending up to 12 nautical miles from the baseline, grants full sovereignty to coastal states, similar to their land territory, albeit with the obligation to allow innocent passage for foreign vessels. Beyond this lies the contiguous zone, extending up to 24 nautical miles, where states can enforce customs, fiscal, and immigration regulations. However, it is the 200-nautical-mile Exclusive Economic Zone that has arguably had the most profound impact, as it allows coastal states exclusive rights to exploit and manage natural resources, including fisheries and energy reserves. UNCLOS also addresses the rights of landlocked states by ensuring access to the seas through transit routes and cooperation with neighboring states. By codifying these provisions, the convention promotes equity among nations and prevents maritime access from becoming a privilege limited only to coastal countries. Furthermore, it establishes rules on the exploitation of the deep seabed beyond national jurisdiction, declaring it the “common heritage of mankind” and mandating that its resources be managed for the benefit of all humanity. An important element of UNCLOS is its contribution to environmental protection. The convention obligates states to prevent, reduce, and control pollution of the marine environment, whether from ships, land-based sources, or dumping. It also encourages cooperation in scientific research, preservation of rare ecosystems, and sustainable use of marine living resources. These provisions reflect the recognition that the oceans are interconnected and that environmental harm in one region can have ripple effects across the globe. UNCLOS has also proven essential in resolving disputes among states. It provides mechanisms for peaceful settlement through negotiation, arbitration, or adjudication by bodies such as the International Tribunal for the Law of the Sea (ITLOS). These mechanisms ensure that maritime disputes, whether over boundary delimitations or navigational rights, are settled according to international law rather than unilateral action or force, thereby reducing the risk of conflict. The convention further enshrines the principle of freedom of navigation and overflight, vital for global trade and security. Given that around 90% of world trade is transported by sea, these provisions protect the lifeblood of the global economy. Naval operations, commercial shipping, and international aviation all rely on the stability and predictability created by UNCLOS, underscoring its role not only as a legal framework but also as a safeguard of global commerce. Over time, UNCLOS has adapted to contemporary challenges. Issues such as maritime security, piracy, illegal fishing, and marine biodiversity beyond national jurisdiction have required new interpretations and agreements supplementary to the convention. Despite criticisms that it cannot fully address emerging issues like climate change and rising sea levels, its framework remains the backbone of modern maritime governance. For countries like the Philippines, UNCLOS is particularly significant, as it provides the legal basis for asserting rights over maritime zones and resources. The 2016 arbitral ruling on the South China Sea dispute, rooted in UNCLOS provisions, reinforced the importance of the convention as a peaceful tool for resolving maritime conflicts, affirming that international law remains the strongest shield of smaller states against larger powers. In sum, UNCLOS has become indispensable in maintaining order in the world’s oceans. It balances the interests of coastal and landlocked states, safeguards navigation rights, promot

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.

Deck Officer

‣ Who is a Deck Officer? A Deck Officer is a licensed seafarer responsible for the safe navigation, cargo operations, crew supervision, and overall safety of the ship. They work under the Captain (Master) and are essential for the smooth operation of the vessel at sea and in port. Responsibilities & Duty Schedule Captain ‣Overall command of the ship, crew, and cargo ‣Ensures compliance with maritime laws & safety regulations ‣Decision-maker during navigation, emergencies, and port operations ‣Represents the ship to port authorities & company Chief Officer ‣Manages deck crew & cargo operations ‣Responsible for ship’s stability, loading, and ballasting ‣Supervises safety drills & emergency preparedness ‣Ensure safe navigation and safety at all times.

PERSONAL PROTECTIVE EQUIPMENT (PPE)

Personal Protective Equipment (PPE) is the frontline defense of every seafarer working onboard. It protects crew members from physical, chemical, and environmental hazards while ensuring safe and efficient operations. Each piece of PPE serves a specific purpose that collectively reduces risk, prevents injury, and promotes a safety-first mindset onboard. 1. Protective Helmet Provides essential head protection against falling objects, impact, and accidental bumps in confined or elevated spaces. A mandatory requirement in all deck and engine operations. 2. Eye Wear (Safety Goggles) Shields the eyes from dust, debris, chemicals, sparks, and flying particles. Crucial during maintenance, grinding, chipping, or chemical handling. 3. Earmuff / Hearing Protection Reduces excessive noise levels from machinery, engines, and power tools. Helps prevent long-term hearing damage and fatigue. 4. Dust Mask (Respiratory Protection) Protects the wearer from inhaling dust, fumes, mist, and harmful airborne particles commonly encountered during painting, sweeping, or chemical tasks. 5. Safety Overalls Flame-retardant coveralls designed to protect the body from heat, sparks, oil splashes, and minor chemicals. High-visibility strips ensure the wearer remains easily seen. 6. Safety Gloves Provides hand protection against abrasions, cuts, chemical contact, and heat. Different glove types may be used depending on the task. 7. Safety Harness Critical for working aloft or in elevated areas. Prevents falls and secures the crew while working at height or over the side. 8. Safety Shoes Steel-toe or composite-toe footwear that protects the feet from heavy impacts, sharp objects, slips, and electrical hazards. Designed for tough marine environments.
