Vessel charter
Chartering a vessel for project cargo
A charter fixes a whole ship, or part of one, for a project’s cargo on the project’s dates and ports. Heavy-lift ships in one fleet offer up to 3,372 m² of free deck and two cranes lifting 2,205 US tons (2,000 t) together[1].
What heavy-lift ships can lift
Ship types in one heavy-lift operator’s published fleet list. The ship on the fixture, not the type, sets the limit.
| Ship type | Cranes | Combined lift | Hold (L × W × H) | Free deck space[1] |
|---|---|---|---|---|
| Type 183 | 1,102 US tons (1,000 t) × 2 | 2,205 US tons (2,000 t) | 351 ft 5 in × 55 ft 9 in × 44 ft 3 in (107.10 × 17.00 × 13.50 m) | 3,215–3,372 m² |
| Orca | 882 US tons (800 t) × 2 | 1,764 US tons (1,600 t) | 351 ft 1 in × 60 ft 8 in × 43 ft 8 in (107 × 18.5 × 13.3 m) | 3,330 m² |
| Type 176 | 772 US tons (700 t) × 2, plus 386 US tons (350 t) | 1,543 US tons (1,400 t) | 351 ft 5 in × 55 ft 9 in × 43 ft (107.10 × 17.00 × 13.10 m) | 2,918 m² |
| Type 116 | 496 US tons (450 t) × 2 | 992 US tons (900 t) | 309 ft 3 in × 53 ft 2 in × 39 ft 8 in (94.25 × 16.20 × 12.08 m) | 2,311 m² |
Full charter, part charter or liner
| Method | Use it when | Avoid it when |
|---|---|---|
| Full charter | The cargo fills most of the ship, or the project needs the ship on fixed dates at ports no liner calls. | The cargo fills only part of the ship: the empty space is paid for. |
| Part charter | A large share of a ship on a voyage the operator already plans. | The project dates do not match the voyage. |
| Liner breakbulk | A few pieces on a regular route. | The project needs a port or date the liner does not offer. |
How a charter is fixed
- 01
Cargo list
Every piece with its weight, dimensions and stacking limits, and the load and discharge ports.
- 02
Ship selection
A ship whose cranes, hold and deck take the heaviest and largest piece[1].
- 03
Fixture
Laycan, freight terms and the time allowed for loading and discharge.
- 04
Stowage and lashing plan
The operator’s engineers place and fasten every piece before the ship arrives.
Rules that apply
- Electronic Export Information (15 CFR 30)U.S. Census Bureau
Electronic Export Information is filed in AES for each Schedule B number worth more than $2,500 going to one consignee on one conveyance, and for every vehicle whatever its value. For vessel cargo it is due at least 24 hours before loading; the Internal Transaction Number (ITN) goes to the carrier with the booking.[2][3]
Applies to: Any Schedule B line over $2,500, and every vehicle
- ISPM 15 wood packagingIPPC, administered in the U.S. by USDA APHIS
Wood packaging and dunnage must be heat-treated to a core temperature of 56 °C for at least 30 minutes, or fumigated, and carry the IPPC mark with the US country code, the facility number and HT or MB. Marked wood can be reused; repaired or remanufactured wood must be treated and marked again.[4]
Applies to: Crates, skids, blocking and dunnage
- Brown marmorated stink bug season: AustraliaAustralian Department of Agriculture, Fisheries and Forestry
Target high-risk goods shipped from the United States between 1 September and 30 April need mandatory treatment, judged by the shipped-on-board date. Flat rack, open top and breakbulk cargo must be treated before it leaves; if untreated, it is refused discharge or sent back. Heat treatment holds 56 °C at the coldest surface for 30 minutes, and for break bulk pieces under 6,610 lb (3,000 kg) 60 °C for 10 minutes.[5]
Applies to: Machinery, vehicles, steel and other listed goods (HS chapters 84, 85 and 87 among them) shipped from the U.S. by sea, 1 September to 30 April
Questions about chartering
When is a charter cheaper than liner shipping?
When the cargo fills most of the ship, or when liner shipping would need transshipments, extra lifts or a long wait for a sailing.
What is laycan?
The window of dates in which the ship must arrive at the load port, agreed in the charter.
Can a chartered ship load at a small port?
Often, because heavy-lift ships carry their own cranes. The port’s depth, berth length and quay strength still have to fit the ship and cargo.
