OOG Cargo / PROFESSIONAL GUIDE

OOG Cargo and Special Containers: Dimensions, Securing and Unloading

The ocean leg is only part of the risk. A successful move begins with accurate engineering facts and a workable unloading site.

THE SHORT ANSWER

Dimensions describe the envelope, not the handling plan. Obtain each item’s mass, centre of gravity, support points, lifting points, fork access and areas that must not take load. Re-measure the as-shipped configuration after bases, packing or protrusions change.

KEY QUESTIONS

Questions to answer before departure

01

What are the maximum packed dimensions and total and point loads?

02

Where are the center of gravity, lifting points and securing points?

03

Can the selected container and terminal accept the over-width or over-height profile?

04

What cranes, permits, escorts, appointments or route surveys are required?

05

Can the final site safely unload and place the cargo?

SHIPMENT-SPECIFIC CHECKS

Before choosing the unit, establish how the load can be supported and moved

The CTU Code is a non-mandatory global packing and securing guide for sea and land transport units. It is not an engineering approval or road permit for a particular move. IMO: the CTU Code

Assign responsibility from the first lift to the final set-down

  • Manufacturer or engineering-data owner: Provide drawings, accurate item masses, centre of gravity, lifting limitations and support points. Identify prohibited lifting or pressure areas and parts that must stay fitted.
  • Loading, securing and carrier teams: Confirm unit capacity, protrusions, supports, blocking and securing. Name the lifting and securing owners; carrier acceptance alone is not an operating method.
  • Local route and unloading teams: Check access, turns, working space and equipment. A forklift needs the appropriate capacity at the actual load centre, fork length, fork access and operating position.

One workable leg does not validate the complete route

Vessel acceptance does not establish destination-port handling, and port capability does not establish road or site access. Keep the plan conditional until the critical equipment and route questions are resolved. Do not infer a forklift rating or a fixed number of lashings from cargo weight alone.

WORKING METHOD

Turn the review into an execution list

01

Measure the cargo as packed

Check each piece’s outer dimensions, weight, centre of gravity, lifting points and packing condition.

02

Compare container and load options

Assess load limits, overhang, handling and route conditions when comparing transport arrangements.

03

Define loading and securing

Specify supports, load distribution, blocking, lashing and the loading and unloading method.

04

Check the whole handling route

Review the factory, terminal, roads, destination port and receiving site together.

DOCUMENTS TO PREPARE

Useful records for the first review

  • Dimensioned drawing and packing plan
  • Weight distribution, center of gravity, lifting and securing instructions
  • Photos of cargo, packing, lifting points and access routes
  • Origin, terminal and delivery-site contacts and restrictions

PROFESSIONAL BOUNDARY

What the logistics plan cannot replace

Carrier acceptance, terminal rules and road restrictions depend on the actual dimensions, weight and route. No container choice should be based on approximate measurements.

Scope and content review

File preparation for open-top, flat-rack, heavy and oversized moves. Unit selection, loads, securing and the route require confirmation from the responsible carrier, engineering and local teams.
