General documentation


Activities associated with many offshore projects often involve the movement of non-routine cargo items which cannot be transported in standard cargo carrying units being shipped between various sites, both on- and offshore.

Such items are often of high value, both intrinsically and in consideration of the consequences of any project delay which might result from physical damage or delay in shipment. By their nature, many of these items may have unusual physical features and / or transportation requirements which may result in particular arrangements having to be made for their safe transportation in a timeous manner.

This document has been prepared to summarise the best practices which experience has shown should be observed the many aspects of the transportation and handling of these items.

It relates principally to items transported to or from offshore facilities on supply vessels and will normally be lifted by, and where relevant set in place, using appliances installed on it and operated by its personnel.

In view of the cranes installed on an offshore facility the maximum weight any item is unlikely to exceed 50 tonnes, though the actual weight of any cargo delivered to it will be determined by the safe working load of the lifting appliances available.

Whilst primarily relating to transportation to or from offshore facilities the recommendations in this document may also be to items being transported to and installed at onshore sites.

Without any references to specific national requirements it may be used on its own throughout the globe. However, when read in conjunction with “Guidelines for Offshore Marine Operations” published by UK Chamber of Shipping and others or “Best Practice for the Safe Packing & Handling of Cargo to & from Offshore Locations” published by Oil and Gas UK, both of which are included as references, the document is particularly useful.

Similar principles will apply to project cargoes transported and lifted by specialist contractors but project-specific procedures and risk assessments will normally be developed for such operations.

MicrosoftOfficeWord  VENDOR LOGISTICS CHECK LIST – This is a word copy of the check list included in “Recommended Best Practice for the Transportation of Non-Routine or Special Cargo Items to or from Site”.

It has been prepared by experienced logistics practitioners with the objective of ensuring that all information required to arrange for the transportation and handling of any unusual items is made available in a timeous manner.

Guidance on the Carriage of Oil Contaminated Cargoes on OSV’s This video has been produced by a cross industry workgroup to highlight the hazards associated with the back loading of oil contaminated cargoes from offshore locations and the good practice that should be followed to minimise the risk of H2S generation. Further information can be found within G-OMO and associated forms.
