IMCA publishes mobilisation checklist for offshore survey operationsIMCA has published a mobilisation checklist for offshore survey operations, for example, a pipeline survey by an ROV. Survey contractors, ROV contractors, pipeline installation contractors and clients have a variety of in house checklists. This document seeks to provide a standard framework for such a checklist. The intent is that it can be used by the contractors themselves and presented to a client or used by the client acting separately. In both cases it seeks to improve efficiency.

Survey contractors, ROV contractors, pipeline installation contractors and clients have a variety of in house checklists. This document seeks to provide a standard framework for such a checklist. The intent is that it can be used by the contractors themselves and presented to a client or used by the client acting separately. In both cases it seeks to improve efficiency:

• It should act as a prompt to ensure the equipment, personnel and procedures are fit for purpose, able to do the work and ready to deliver the contemplated operation to the satisfaction of all parties;
• It should act as a catalyst towards a 'no surprises situation'. Surprises usually mean delays in mobilisation which can be expensive for all parties;
• It should help to deliver safe and efficient operations.

The document provides a framework to build either a brief or detailed mobilisation checklist for survey support operations. The document could be expanded to cover any offshore survey operation; the extent of the checklist developed depends on the complexity of the survey operations which could include:

• Pipeline/subsea architecture condition surveys;
• Pipeline/subsea architecture post installation surveys;
• Pipeline/subsea architecture installation support observations (and installation/construction support).

For specific LBL acoustic and INS operations additional information may be required to reflect specific technical requirements and survey specifications. The person completing the checklist may require access to the complete scope of work, survey specification, tolerances and procedural documentation required by the survey team to perform the tasks required.

The comments sections - 2.3, 3.4, 4.8, 5.9 and 6.4 - can be used for additional comments or observations not covered by the checklists.
