Voltim Global

Project Logistics

Project logistics is the end-to-end planning, engineering and execution of transport for large-scale industrial and infrastructure projects, where every component — from a 330-tonne reactor vessel to thousands of tonnes of structural steel — must reach the construction site in a contractually defined sequence. Voltim Global, with offices in Istanbul, Mersin and Moscow, coordinates this entire chain from a single point, from feasibility studies through to final site delivery.

How does project logistics differ from standard freight forwarding?

Standard freight forwarding moves repeatable, containerised shipments along established schedules. Project logistics, by contrast, is engineered around a construction programme: each movement is a one-off operation involving out-of-gauge dimensions, extreme weights and a fixed erection sequence, where a late arrival can idle cranes, crews and contractual milestones. The discipline therefore starts long before transport — with load analysis, route surveys and critical point identification covering bridges, tunnels, overhead lines and turning radii. Under the Turkish Highway Traffic Regulation, a road movement exceeding the general limits — 2.55 metres in width, 4 metres in height or 40 tonnes gross combination weight — requires a Special Load Transport Permit, so permit engineering is part of the plan from day one. Voltim Global performs this engineering feasibility — load analysis, route study and critical point identification — and carries out oversized and heavy cargo moves with its partner network as an integrated part of the wider project plan.

How is logistics planned under FIDIC and EPC contracts?

In EPC and turnkey projects — typically contracted under the FIDIC Silver Book, which places design and execution responsibility on the contractor — logistics failures translate directly into delay damages. Logistics planning therefore has to mirror the contract itself: delivery obligations, milestone payments and site handover dates are converted into a transport schedule with defined responsibilities at every interface. Voltim Global joins projects at the feasibility stage, well before mobilisation, so route studies and permit lead times can be priced into the tender. During execution, weekly progress reports, KPI and milestone tracking give the EPC contractor documentation aligned with its own employer reporting, while project cargo and erection All Risks insurance closes the risk allocation between marine transit, inland transport and on-site handling.

Why does critical path analysis matter in project cargo logistics?

Critical path analysis identifies which cargo movements directly determine the project completion date. A steam turbine, transformer or reactor component is usually a long-lead item: if it arrives late, erection stops, and every downstream activity slips with it. Logistics planners therefore classify each consignment by float — how much delay it can absorb before touching the critical path — and build buffers around the items with none. Permit approvals, vessel fixtures, seasonal road restrictions and port congestion are all mapped as schedule risks. Voltim's critical point identification and route studies feed this analysis: a longer routing that avoids a weight-restricted bridge may protect weeks of programme time. The output is a transport plan sequenced against the construction schedule rather than against transport convenience.

How is multimodal transport coordinated on a large project?

Large project components rarely move door-to-door by a single mode. A typical chain combines a heavy-lift or breakbulk vessel for the ocean leg, river barges or rail for inland corridors, and hydraulic modular trailers for the final kilometres — with engineered transhipments at each interface. The risk in multimodal operations concentrates at those interfaces: lifting plans, lashing calculations, quay strength and crane capacity must all be verified before the cargo ever ships. Voltim Global coordinates sea, road, river and rail combinations from a single point, plans port and rail transhipments, and integrates transit customs declarations so cargo is not held at borders between modes. Cargo classes and handling methods are described in detail on our project cargo page.

How are site delivery windows managed?

Construction sites take deliveries in windows, not at will. Laydown areas are limited, heavy-lift cranes are booked by the day, and erection crews work to a fixed sequence — so a component arriving early can be as disruptive as one arriving late. Delivery windows are agreed with the site erection team and locked into the transport schedule; oversize road convoys in Türkiye typically move at night under escort, within the route and time conditions written into each Special Load Transport Permit. For Türkiye's first nuclear power plant at Akkuyu, Voltim has delivered more than 450 supply shipments to the site region since March 2024, with permit management and daily reporting, so the customer always knew which shipment would arrive, and when. That daily cadence — rather than weekly summaries — is what site delivery management demands.

How are nuclear and energy project components transported?

Energy projects generate the heaviest single pieces in logistics. According to World Nuclear News, the VVER-1200 reactor pressure vessel installed at Akkuyu — a plant of four units totalling 4,800 MWe, per the World Nuclear Association — weighs some 330 tonnes at 4.5 metres in diameter and 12 metres in height. Pieces of this class travel by heavy-lift vessel to a project berth and then by self-propelled modular transporters over engineered routes, with civil works wherever the ground or existing structures cannot carry the load. The same methodology scales across thermal, hydro, wind and solar projects, refinery and gas processing plant modules, mining conveyor systems, and bridge, tunnel, metro or airport segments. Voltim's nuclear scope is presented on the nuclear project transportation page.

Key facts: project cargo logistics

Under the Turkish Highway Traffic Regulation (Article 128), road vehicles are limited to 2.55 m width, 4.00 m height and 40 tonnes gross combination weight for five-or-more-axle combinations (44 t only for certain intermodal container combinations); loads beyond these limits require a Special Load Transport Permit for each movement.
According to the World Nuclear Association, the Akkuyu plant comprises four VVER-1200 units totalling 4,800 MWe and is expected to meet about 10% of Türkiye's electricity needs.
World Nuclear News reports that the VVER-1200 reactor pressure vessel installed at Akkuyu unit 1 weighs 330 tonnes, measuring 4.5 m in diameter and 12 m in height.
According to the IAEA, construction of Akkuyu unit 1 — Türkiye's first nuclear power plant — began in April 2018.
The FIDIC Silver Book is the international standard contract form for EPC/turnkey projects, placing design, execution and schedule responsibility on the contractor — the framework within which project logistics plans are drafted.

Frequently Asked Questions

What is project logistics and which projects does it cover?

Project logistics is the integrated management of all logistical components of large-scale industrial and infrastructure projects, coordinated from a single point. Voltim Global plans project cargo services for energy, industrial and infrastructure projects and carries them out with its partner network, from feasibility to site delivery.

How is the project logistics process managed?

The project logistics process starts with engineering feasibility and is managed from a single point through to site delivery. The first phase covers load analysis, route study and critical point identification; transport, customs and site logistics are then coordinated as one integrated plan. Voltim Global provides weekly progress reports, KPI and milestone tracking throughout, and applies daily reporting, as on its supply shipments to the Akkuyu nuclear power plant site region.

Which transport modes are used for project cargo?

Project cargo moves via multi-modal combinations of sea, road, river and rail transport. The optimal combination is defined through route study and load analysis, while port, rail and road transhipments plus on-site logistics are executed under a single plan. Voltim Global uses this multi-modal approach for its supply shipments to the Akkuyu site region, around two-thirds of which have moved via the Tuapse–Taşucu Ro-Ro line and the rest by road.

Which documents and permits are required in project logistics?

Project logistics requires export, import and transit customs declarations, plus route-specific special permits. Voltim Global coordinates customs through its contracted customs brokers as part of the service and takes on permit management within the project scope. Project cargo and erection insurance (All Risks) policies are also arranged through partner insurers. Exact documentation depends on the destination country, cargo type and route, and is clarified during the feasibility phase.

How is project logistics pricing determined?

Project logistics pricing is determined by a detailed logistics plan prepared for each individual project rather than a standard tariff. Load analysis, route study, the multi-modal combination used, number of transhipments, customs procedures, insurance coverage and site logistics requirements all shape the cost. Following the engineering feasibility study, Voltim Global provides a detailed logistics plan and quote for your energy or industrial project.
