SISMAR

Based in Istanbul, Turkey, SISMAR serves the global maritime industry as a specialized ship supply and services provider. Established in 1998, the company has developed its operational infrastructure to support vessels calling at Turkish ports, calling at shipyards, or transiting through the region’s critical waterways. Operating legally as Sismar Ship Supply & Services, the entity functions primarily as a ship chandler, a role that involves managing the logistical complexity of delivering essential provisions, technical equipment, and spare parts to merchant ships. The company’s headquarters in the Karaköy district of Istanbul places it at the center of one of the world’s busiest maritime corridors. From this vantage point, SISMAR coordinates logistics across the entire Turkish coastline, including the Sea of Marmara, the Aegean, the Mediterranean, and the Black Sea. A significant portion of its operational focus is directed toward the Turkish Straits - the Bosphorus and the Dardanelles. These waterways are vital arteries for international trade, and SISMAR provides specific transit supply services designed to meet the needs of vessels passing through these channels without requiring them to anchor for extended periods. This capability is essential for ship operators looking to minimize downtime and avoid the costs associated with port delays. The scope of SISMAR’s supply operations covers the full spectrum of vessel requirements. While the company handles general provisions such as food and cabin stores, its technical division supports the engineering needs of the fleet. This includes the procurement and delivery of deck and engine stores, electrical components, valves, bearings, and safety equipment. The company also manages the supply of nautical charts, publications, and medical items, ensuring that vessels remain compliant with international safety and navigation standards. Beyond the delivery of physical goods, the company integrates customs clearance and logistics management into its service workflow. This is particularly relevant for the delivery of ship spares in transit, where timing is critical. By coordinating between local manufacturers, international suppliers, and vessel schedules, SISMAR acts as a logistical bridge, ensuring that supplies reach the gangway efficiently, whether the ship is docked at the Tuzla and Yalova shipyard zones or maneuvering through the straits. Through these activities, the company maintains a specific role in the regional maritime ecosystem, supporting the operational continuity of commercial shipping in Turkey.
