Inspection
Visual inspection e.g. inspection of structural members, pipelines, subsea equipment, cables, risers, sumps, clamps, conductors, and boat landings Non Destructive Test (NDT) e.g. flooded member detection, ACFM, MPI, and UT-Scan Cathodic protection inspection e.g. the corrosion level and status of anode depletion Location and identification of debris on or in the vicinity of structures, pipelines or any other offshore facilities Examination and measurement of damaged areas on structures, pipelines or any other offshore facilities e.g. coating damage and dent Measurement e.g. free spans, dept of burial, scouring, marine growth and member thickness Marine Growth InspectionSeabed profile survey e.g. using side scan sonar survey and multi-beam survey Class Underwater Inspection In Lieu of Drydocking (UWILD) and mooring inspection
Maintenance and Repair
Replacement or installation of underwater structural mambers, subsea equipment, pipelines, risers, cables, valves, caissons, sumps, retrofit clamps such as :
♦ Cut and Remove existing riser and/or pipeline sections including recovery of cut riser and/or pipeline samples
♦ Install riser clamps and/or guards for risers
♦ Install new riser and/or pipeline spools including tie-ins
♦ Install pipeline mechanical connectors and/or clamps
♦ Install valves such as SSIV, check valves, etc
♦ Install flange protectors, protection frames, concrete mattress, end caps etc. for pipelines
♦ Install subsea launcher and/or receiver for pipeline cleaning, gauging, hydro testing, dewatering and inerting
♦ Install conductor guides for structural members
♦ Install boat fenders Replacement or Installation of anodes for structural member and pipelines Stabilization of structural and pipelines using grouting system or other methods Removal of debris on and in the vacinity of structures, pipelines or other facilities Replacement of mooring buoy, subsea hoses, mooring chain and floating hoses for Mooring Buoy System and FPSO/FSO facilities
