Special Periodic Surveys (SPS) and System Integration Testing (SIT)
Classification Societies and require differing levels of SPS Surveys to be conducted at various stages of a Rigs Life. This involves detailed structural investigation and various inspections to ensure structural watertight integrity. During the Special Periodical Survey many companies take the opportunity to plan and conduct upgrades and maintenance to major equipment during this downtime period. OCS can greatly lighten the burden for clients by either managing or assist with these projects. OEM and Various Equipment Manufacturers also require recertification of their equipment usually on a 5 years basis. SPS / OEM recertification of equipment are often conducted at the same time due to convenience as the rig will be out of service during this period as the rig will go to dry dock. OCS can manage these projects with its experience management teams and also Project Software.
Special Periodical Surveys (SPS) and Upgrades and Maintenance
Classification Societies require differing levels of SPS Surveys to be conducted every 3, 5, 10 and 15 years.
This involves detailed structural investigation and various inspections to ensure structural watertight integrity.
Simulation Integrated Testing (SIT)
An SIT is sometimes known as an “Integration Acceptance Test” (IAT) and is usually conducted in the following circumstances;
The SIT will help to prove the following subject matters:
- To test all the drill floor equipment crossing system boundaries to ensure integrate with the various tools, other equipment and systems within the drilling and LP & HP mud systems
- Will help ascertain the reliability of the equipment through continuous operation and cycling of functions and procedures through a set period (24 to 72 hours). Will ascertain the flow characteristics and capacity of the mud system.
- Will test the capability of the power and electrical systems to operate under continuously load
- Set baseline parameters of both temperatures and pressures for various running conditions
- Test the competency of the crew in operation of the rigs equipment and systems
