INGENIEUR
4 . Offshore crews , these are the people who operate and maintain the ROV during offshore operations .
5 . Onshore base support team including : a . The Engineering Manager who oversees and manage the engineering and workshop team members . b . An Electrical engineer who is well versed in the electronics / electrical system of an ROV . c . A Mechanical engineer who is responsible for all aspect of the hydraulic and mechanical elements of the ROV system . d . Base technicians , including a supervisor , mechanical and electrical technicians . They are normally the ones who are responsible for the onsite assembly , repair and maintenance of the ROV . In certain circumstances , they will be sent offshore to do major repair and maintenance activities which the offshore crew cannot handle .
In most cases , the mechanical and the electrical engineers are experienced practical people who can help in the assembly and maintenance project of an ROV .
An offshore project that involves an ROV may be as short as a day or as long as two to five years , depending on the project requirements . In addition , mobilisation and demobilisation periods have to be taken into the job planning and costing which varies according to the type of ROV being used . Figure 6 shows the typical workflow process of a ROV project .
FIRST PHASE Before a contract is awarded , a meeting between the client and the contractor is held to identify the project requirements and any potential obstacles that will have to be tackled . Engineers and the vessel surveyors visit the chosen vessel / oil rig to check its layout and determine if it is suitable for the intended ROV system . The client will provide a general deck layout drawing of the particular vessel / oil rig and the ROV engineers determine a suitable location for the ROV to operate .
FIRST PHASE SECOND PHASE
THIRD PHASE
Client request for quotation ( RFQ )
- Engineers study the requirements and respond to the contract department
Contract awarded
- Notice given to contractor to prepare mobilisation
- Administrative assistant begins to search for an offshore team
- Engineers start to contact all vendors for certification and additional tools and sensors
- Technicians start to do final maintenance and touch up on the ROV
ROV System Mobilisation
- The ROV team is allowed a few days to mobilise and setup the ROV on a vessel or rig .
- In many cases , the onshore base team will be sent . Offshore crews arrive once the system is ready .
Operations Start
- Vessel reaches job site . - Operation engineers monitor the whole project progress .
End of Project
- ROV and crews demobilised from the vessel .
- Job completion certificate is issued by client .
