Sapesco marine division, “Sapesco Offshore Services (SOS)”, provides Work Remote Operated Vehicles (WROV) for intervention and deep water topographical and pipeline surveys to very high international marine standards.
Equipment operates on vessels fully equipped to handle the constant stream of Dynamic Positioning System (DPS) Data provided from multiple sources.
Sapesco SIS provides complimentary services for all downstream activities including coiled pipe lay up to 4 ½” OD schedule 80, together with infield cable lay, power cable lay between shore and platform and platform to platform.
Where offshore platforms may prohibit the offloading of equipment due to size or weight restrictions, Sapesco SIS can mobilise DNV 2.7-1 containerised units for work from barges and supply boats.
An extensive array of equipment is available and this includes, but is not limited to the following: -- Liquid Nitrogen Storage tanks
- Nitrogen Pump Units
- Large Volume High Pressure Oil Free Air Compressors
- High Volume Low Pressure Air Compressors
- Desiccant Drier Units
- Portable Mass Spectrometer Laboratories for Commissioning Leak Testing Services
- Portable Hydrotest Cabins
- Zone 1 (Electrical) and Zone 2 (Diesel / Hydraulic) pump units.
- SAE AS 4059 (NAS 1638 Class 3) 3-micron high pressure flushing units
- Mechanical Services Stud Bolt Torque and Tensioning Systems.

Coiled Tubing Pipeline Laying (Reeled Pipe).
Coiled Tube Pipeline is a relatively new technology. The service offers an economical alternative to conventional sub sea control lines and offshore small diameter flow line construction techniques.
Additionally, simple installation of onshore surface or buried flow lines for gathering centres, tie-ins and high-pressure injection lines.
Coiled Tubing Pipeline has the following advantages over conventional pipelines: -
- Higher Strength and Pressure Rating.
- Several Kilometres without Tube Welds.
- Elimination Of The Cost Of Welding, Heat-Treatment, X-Ray And Inspection Services.
- Dramatic Reduction of Installation Time and Equipment.
- Excellent Flow Characteristics and Design Life.
- Hydro-Tested And Corrosion Protected At The Plant.
In addition to a full oil and gas field capability, Sapesco have Coiled Tubing Pipeline lay equipment and technology for laying Pipelines up to 4½" diameter.
Equipment is also suitable for laying submarine multi-core communications cables, umbilical hydraulic lines and electrical power cables.
