Drops Object Survey


Tubestar is a member of the DROPS forum and supports the aims and objectives of the UK's Dropped Objects Prevention Scheme (DROPS). Dropped Object Surveys and Inspections are a key element of dropped object control and prevention management systems.

Tubestar can help prevent a potential dropped object becoming another unwelcome safety statistic by conducting detailed dropped object survey of hazardous areas. We are all committed to preventing harm to personnel and damage to equipment from dropped objects. Tubestar provides qualified inspectors to conduct a thorough dropped object survey of the derrick and other areas as required.

All the areas which are to be inspected are divided under different zones and are surveyed as per Client's dropped object policy. All the findings are recorded in the report with photographic evidence and corrective actions for the same. Report is divided in to two parts, one is the Inspection Survey which includes all observations and another is the Failed Items list which covers the items which failed in the survey.

Generally Survey tasks are:

  • Document equipment location by Inspection Area
  • Photograph each item surveyed
  • Include unique identification number to each item (tag numbers)
  • Describe each item surveyed
  • Inspect and document Primary Securing method(s)
  • Inspect and document Secondary Retention method(s)
  • Record equipment condition as Pass or Fail, including comments (ie Satisfactory or Reason for Failure)
  • Record inspection frequency (ie weekly, monthly) as recorded in the Equipment Family Inspection Criteria
  • Generate a Failed Items List

Dropped objects pose a significant threat to personal safety; they also have the potential to cause damage to structures, plant and equipment leading to loss of containment and consequential release to the environment.

Cargo Handling

  • Inspection and recertification of Containers / Baskets and Pallets
  • Proof load Testing Services

Load testing is carried out by competent inspectors who are competent as per local regulations or qualified by LEEA / NSL. In addition they are certified to ASNT Level II. Tubestar has in-house testing facility with tensile test beds for pull testing of loose lifting equipments like slings, shackles etc upto 100 Tons. We have customized hydraulic jacking units to load test pad eyes offshore upto 30 Tons. Hydraulic jacking unit is mounted on the pad eyes and load tested at required proof loads.

Eddy Current Inspection


More and more companies are opting to go in for Eddy current inspection due to inherent benefit of non-requirement of paint removal for inspection which is a drawback in the conventional NDT method of MPI. Eddy current eliminates the need of surface preparation and saves lot of time in paint removal and re-application of paint post inspection. Only at places indications received prove-up is done with MPI.

One of the major advantages of eddy current as an NDT tool is the variety of inspections and measurements that can be performed. In the proper circumstances, eddy currents can be used for:

  • Crack detection
  • Material thickness measurements
  • Coating thickness measurements
  • Conductivity measurements for:
    • Material identification
    • Heat damage detection
    • Case depth determination
    • Heat treatment monitoring

Some of the advantages of Eddy current inspection include:

  • Sensitive to small cracks and other defects
  • Detects surface and near surface defects
  • Inspection gives immediate results
  • Equipment is very portable
  • Method can be used for much more than flaw detection
  • Minimum part preparation is required
  • Test probe does not need to contact the part
  • Inspects complex shapes and sizes of conductive materials

Tubestar has onboard trained and qualified inspectors to carry out Eddy current inspection onshore and offshore. Tubestar uses the latest state of the art Phasec-3D unit from GE for inspection.

Rope Access


Rope access system (initially developed from the Mountaineering techniques) is a form of work positioning system which permits access to difficult to reach locations without use of Scaffolding, Cradles or Aerial platforms. Rope Access Technicians traverse on ropes to access work locations while suspended by their harness. This technique utilizes a back up fall arrest system which ensures redundancy. Rope access techniques have been used by the Industry for more than three decades and has an excellent safety track record.

Advantages :

  • Time saving.
  • Cost effective.
  • Safe.
  • Highly adaptable.

Tubestar a front runner in the Rope Access field offers complete Inspection, Maintenance and Repair services utilizing IRATA qualified technicians. IRATA safety procedures are being strictly adhered to. Compliance to ISO 22846-2:2012 & EN standards.
