Service Warranty The data presented within the report and associated charts/drawings have been acquired and processed to meet the requirements of the contract as agreed by End Client and Contractor. Any unauthorized use of the information presented within this report and charts/drawings is prohibited. Contractor will not accept any liability if the data is used for purposes other than those agreed in the contract. Subsea cables and thin pipelines can be very difficult to detect due to their small diameter. Unless their existence and approximate location is made known prior to the commencement of the survey work, there is a possibility that they may not be represented in these documents and the user should take the necessary precautions. The information presented in this report and associated charts/drawings are based on the interpretation of the external visual inspection and will not provide accurate details of any features which are not entirely and/or clearly visible.

Project Scope of Work The scope of work to be carried out by contractor under this contract was to undertake ROV pipeline inspection offshore the United Arab Emirates. The scope of required services can be summarized as follows:

1.2.1.

Pipeline Survey The scope of work to be carried out by contractor under this section of the contract was to conduct inspection surveys of existing pipeline infrastructure in the Field Name field, offshore United Arab Emirates. The scope of required services can be summarized as follows 

ROV inspection survey of No of surveyed pipes subsea pipelines (approximately Total Length of pipes/cables Km).

The purpose of the pipeline survey was the visual assessment of the basic properties (presence / absence, overall integrity, obvious damage, surface condition, etc.) of the pipeline and associated attachments. 1.2.2.

Platform Inspection The scope of work to be carried out by contractor under this section of the contract is to conduct external inspection surveys of designated platforms in Field Name, as part of the End Client Name routine platform inspection project. The scope of required services can be summarized as follows: General Visual Inspection (GVI): Cathodic Protection and Anode Survey: Riser Survey: Riser Clamp Survey:

1.2.3.

Optional Work The client had informed contractor that upon completion of the pipeline survey/platform inspection addition survey operations may be required to be undertaken by the ROV, these being: 

Seabed survey.



Spud can survey.

The client confirmed all optional work prior to the completion of pipeline survey/platform inspection operations

ROV Inspection Notes 

All times stated within the report are GMT + 4Hrs. (UAE Local time).



Video data was recorded at the time of the survey. KP values displayed on the video overlays are raw and were derived by using the client supplied databases. KP values stated in the report document are generated from the processed track of the ROV thus; a variation may occur between the raw KP values displayed on the video overlays and the KP values stated within this report document.



Events visually observed both during the initial survey and post review are presented within this report document. Events that were obscured from view of the cameras (i.e. an event covered with sufficient marine growth to hide its appearance) were not recorded and are not presented within this report document.



No “Fitness for Purpose” comments or conclusions are present within this report document.
