Knowledge hub
Practical maritime knowledge on ship supply, repair, agency, customs and marine engineering.
Round the clock ship service operations work because staffing, stock and communication are structured for it in advance, not because someone happens to answer the phone at 3am; the difference shows up in how fast a vessel actually gets served.
Read article→The Bosphorus and the Dardanelles carry tens of thousands of vessel transits a year, making them among the busiest waterways in the world, which means transit planning, pilotage and local support are routine parts of doing business through Türkiye.
Read→Mersin anchors ship services along Türkiye's East Mediterranean coast, giving vessels transiting to or from the Suez route access to supply, agency and repair support without a long detour from their main course.
Read→A WPQR proves that a welding procedure produces a sound weld, while IACS approval proves that a specific welder can execute that procedure reliably in production. A fabricator needs both to produce structural welds that class societies will accept.
Read→İzmit Bay's ports offer tankers and bulk carriers direct access to a dense cluster of refineries, petrochemical plants and heavy industry, which is why so much of Türkiye's liquid and dry bulk trade moves through this stretch of the Marmara.
Read→A free zone lets cargo be stored, handled, or lightly processed outside the standard customs territory, which is useful when goods will move on to a third country or need to sit for a while before their final destination is decided. It is not a general shortcut, and it only pays off when the shipment's own pattern actually needs that flexibility.
Read→A protecting agent is appointed by the shipowner to safeguard the owner's interests during a port call, while a charterer's agent, sometimes the same person handling the operational husbandry, is appointed by the charterer to manage the call; the two roles can overlap in practice but exist to represent different parties.
Read→Custom marine steel fabrication moves through five linked stages: capturing the operational requirement, engineering it into a buildable design, cutting and forming the steel, welding and assembling the structure, then finishing, testing and delivering it. Each stage feeds information back to the ones before it.
Read→Ambarlı is Istanbul's container and general cargo hub while Tuzla is its shipyard and repair district, so the right choice depends on whether a vessel needs a commercial cargo call or technical work, not on which port is closer.
Read→Choosing a shipyard on price alone is one of the most common causes of a docking that runs late or over budget. These ten questions cover what actually determines how a docking goes.
Read→Turkey sits at the point where the Mediterranean, the Black Sea, and land routes into the Middle East and Central Asia meet, which is why cargo bound for a wide arc of neighbouring ports is often routed through a Turkish port or airport rather than shipped direct. The advantage is geography combined with the customs and transport tools that let goods move onward without unnecessary delay.
Read→The right time for a main engine overhaul is set by running hours, condition data and the manufacturer's maintenance schedule together, not by a single fixed interval. Here is how owners usually decide.
Read→Getting a manufacturer's service engineer or a specialist technician on board a vessel in a Turkish port depends on the same building blocks as any crew movement: a valid visa or entry permission, a boarding permit from the port authority, and enough lead time for the agent to arrange both before the vessel arrives.
Read→Tuzla became Türkiye's shipyard district because dozens of yards, repair facilities and marine service companies sit side by side along a short stretch of coast near Istanbul, giving vessels access to almost every trade they need in one place.
Read→A part removed from a ship in a Turkish port, whether faulty, replaced, or sent ashore for repair, can usually be sent back out of the country under customs procedures that recognise it never entered local trade. Getting this right depends on documenting the part's history from the moment it comes off the vessel.
Read→Selecting mooring equipment means matching line type, winch capacity and fairlead or bollard placement to the vessel's size, berth and expected environmental loads, not just buying the strongest components available. Getting the combination wrong creates chafe, snap back risk or equipment that cannot hold the vessel safely.
Read→Ship supply prices are shaped by the underlying market cost of goods, but also by lead time, delivery method, order size and how much sourcing effort an item requires, which is why the same item can be quoted differently between two port calls.
Read→Getting a repair team onto a vessel at short notice, sometimes in a foreign port, depends on logistics as much as technical skill. Here is what mobilising a riding squad actually involves.
Read→A port disbursement account is the itemised statement of everything a vessel's port call cost, and understanding it means knowing the difference between the proforma estimate issued before arrival and the final account issued after departure, plus what each line item actually covers.
Read→A subsea pipeline project needs marine support long before and after the pipe touches the seabed, covering everything from survey and pipe logistics at the coating yard to the vessels, ports and inspection work that keep installation on schedule.
Read→An urgent request is manageable when the vessel names its true priority items first, gives an honest arrival estimate, and accepts that some items may need to be sourced from a wider net or substituted at short notice.
Read→Getting an urgent spare from an incoming flight to a waiting vessel comes down to three things happening in parallel rather than in sequence: customs clearance, ground transport, and coordination with the ship's schedule. Miss the overlap and the fastest flight still arrives too late.
Read→The right material for a seawater application depends on what mix of strength, weight, corrosion resistance and galvanic compatibility with neighbouring metals it needs, not on which metal is generically the toughest. Stainless steel, hot dip galvanised steel and aluminium each win in different situations, and mixing them without care creates galvanic problems.
Read→A cold chain delivery stays within the correct temperature range from the moment goods leave storage until they are checked in at the gangway; the main risks are the time spent loading, transporting and transferring goods, not the vessel's own reefer store.
Read→A ship's coating system only performs as well as the surface preparation beneath it. Getting blasting, primer and antifouling choices right protects steel and controls fuel consumption between dockings.
Read→A crew change in Türkiye works when the paperwork, immigration formalities and travel logistics are lined up before the vessel arrives, since the actual changeover at the quay or by launch usually takes only a short window once everyone and everything is in place.
Read→Safe offshore transfer of people and equipment comes down to three things done consistently: trained personnel using approved routes and gear, equipment secured and rigged correctly, and every transfer stopped rather than rushed when conditions are marginal.
Read→Ordering marine chemicals and lubricants correctly comes down to matching the exact grade and specification to the equipment maker's requirement, confirming compatibility before mixing products, and keeping proper documentation for handling and disposal.
Read→Steel renewal on a ship's hull is decided by measured plate thickness against class-allowed limits, not by visual condition alone. Here is how the measurement, reporting and renewal process works.
Read→Transit status lets a spare part move through Turkey, from the border or port of arrival to the vessel, without becoming a domestic import along the way. It is a routing tool, not a discount, and it only works when the paperwork tracks the part from start to finish.
Read→A pontoon is a buoyant steel or composite structure used to create floating platforms for marinas, walkways, work decks and temporary bridges. It is built as a sealed, compartmented hull that provides stable buoyancy under a moving deck load.
Read→A vessel that does not berth can still be supplied, usually at anchorage or on a slow pass through a strait, by launch or barge, provided the order, timing and sea conditions are coordinated well in advance.
Read→The Çanakkale Strait (Dardanelles) shares the same reporting and pilotage framework as the Istanbul Strait but differs in its geography, traffic pattern and the role weather plays in transit timing, so a vessel bound for the Dardanelles needs its own transit plan rather than reusing Bosphorus assumptions.
Read→Clearing ship spares in Turkey means matching the part to the vessel's call, presenting the right paperwork, and applying the correct customs regime, whether the goods are ship's stores, a repair item, or cargo moving onward. Handled correctly, most consignments clear within the vessel's port stay.
Read→Offshore energy projects in Türkiye, from oil and gas platforms to survey and cable work, depend on a layer of marine services onshore that most people never see: port agency, supply, vessel support and marine engineering.
Read→An equivalent spare is a part that meets the same technical specification as the one requested but comes from a different manufacturer; used correctly, it keeps a vessel moving without compromising safety, but it must always be proposed, not assumed.
Read→Many repairs do not require taking a vessel off-hire. Riding squads, port stays and even work carried out at anchorage can close out a surprising share of a ship's maintenance backlog.
Read→A port agent in Türkiye is the vessel's local representative, handling every touchpoint between the ship and the shore, from pre-arrival planning through customs, port authorities and disbursement accounts, so the owner or operator does not have to deal with each office directly.
Read→Class societies require gangways and accommodation ladders to carry a certified safe working load, be fitted with compliant handrails and non-slip treads, and remain safe to use across the ship's operating range of angles. The rules cover the structure, its fittings and its ongoing inspection, not the ladder alone.
Read→Fresh provisions need a more precise, earlier request than dry stores because quality, quantity and market availability all shift day to day; requesting two to three days ahead, with clear specifications, gives the best result.
Read→A dry-docking that runs smoothly is decided months before the vessel arrives at the yard. The work starts with a specification list, a yard booking and a realistic schedule, not with the ship already alongside.
Read→Offshore logistics succeed when people, equipment and consumables reach the field on schedule and in the right condition, which depends on coordinated port operations, the right vessel and tightly planned handovers.
Read→Ordering ship provisions well means sending a clear requisition early, confirming quantities and delivery point, and leaving room for last-minute changes; the process runs smoothly when the supplier, agent and vessel all work from the same information.
Read→The Istanbul Strait is one of the world's busiest waterways. Here is what owners and masters should know about transit, formalities and husbandry support.
Read→Cathodic protection is what keeps hulls, pipelines and offshore units from corroding. Here is how sacrificial anodes work and where the DNV RP-B401 standard fits in.
Read→Not every repair needs a dry-dock. Understanding when afloat repairs, riding squads or a full docking is the right call can save significant off-hire time.
Read→IMPA codes give ship suppliers and crews a common language for marine stores. Here is what they are, how they work, and why they prevent costly ordering errors.
