Rov survey and statutory inspection of subsea infrastructure – petrosa (ctt 26938)

PetroSA operates 4 gas and condensate fields tied to the FA Platform. The EM field has 7 wells connected via a daisy-chained 18" pipeline of ~50 km with 9 subsea structures (PLEM, SDU, lateral structures, pigging skids). Two wells are controlled from FA Platform via electrohydraulic umbilical; the rest connect to the unmanned EM Buoy via radio link. The Ikhwezi Field has 3 producing wells connected via ~37 km daisy-chained 12" and 8" rigid/flexible pipelines with 4 subsea structures (TIFs, metering skids), controlled via electrohydraulic umbilical. Both fields have a 3" MEG line piggybacked to the main production pipeline. The inspection covers EM, SCG, FO, and Satellite fields.

Personnel requirements: all personnel must hold valid offshore survival certificates and full offshore medical certificates (written in English, detailing the medical tests conducted). Non-South African personnel must have a Section 11(2) visa with authorization to work in South Africa, approved before travelling; PetroSA will provide support letters.

Scope: statutory inspection of subsea infrastructure using a Remote Operated Vehicle (ROV) on PetroSA gas and condensate fields (EM, SCG, FO, Satellite, Ikhwezi). Work includes: visual inspection of all subsea infrastructure; continuous cathodic protection (CP) measurement using voltage gradient method; contact CP stabs at anodes or bare metal at 12 m intervals along pipelines; estimate percentage anodes remaining; continuous pipeline depth profiling; record free span start/end coordinates (WGS84) and estimate free span height; note debris within 2 m radius of pipeline; record 3" piggyback line start/end coordinates where detached; CP contact measurement on 3" piggyback line at 50 m intervals; note buried pipeline sections with start/end coordinates; note gas leaks; excavate using jetting tool to at least 3 m deep, 3.6 m wide, 4 m long around main pipelines (total 25 excavations); recover and swap excavation tool with CT scan inspection tool and inspect excavated sections. Excavation/CT scan counts by field: SCG – 14" (6), 12" (4), 8" (1); EM – 18" (6), 12" (1); Satellite – 10" (1), 8" (1); Ikhwezi – 12" (4); total 24. Structures (PLEM, SDU, pigging skids, LATs, SSXTs): CP stab on at least 5 points per structure (e.g., corners and top centre); check for damage/anomalies on structures and associated umbilicals/flexible flowlines; check for gas leaks on flanges or from structures; note debris within 2.5 m radius; record centre point coordinates (WGS84); record water depth on top and seabed bottom. Service provider must supply all topside and subsea survey/inspection equipment and consumables, including ROV-mounted CP probes, cameras, seabed profilers, depth sensors, altimeters, excavation and CT scan tools. Minimum personnel: Party Chief, Data Recorder/Party Chief Assistant, CAD operator, 2 online surveyors, 2 video logging personnel, 2 corrosion engineers, 2 excavation tool operators, 2 CT scan inspection personnel. PetroSA supplies: DP2 Platform Supply Vessel, mobile crane with operator and rigging personnel for in-harbour lifting, and documentation (pipeline alignment sheet, field layout diagram, vessel deck layout). Deliverables: 3 hard copy survey reports (anomalies, damages, free spans), corrosion and CT scan report, 3 soft copies on external hard drive with media files and raw data, daily progress report. Work executed in two campaigns: Campaign 1 – mobilization/installation of Work class ROV with excavation and CT scan tools onto DP2 vessel, offshore execution, demobilization; Campaign 2 – mobilization of survey team with tools to Mossel Bay, installation of survey spread onto Inspection Class ROV, offshore execution, demobilization.

Quality requirements: all survey and inspection equipment must be calibrated and tested together with the vessel and ROVs before execution. Deliverables must include 3 hard copy survey reports noting anomalies, damages, free spans; corrosion and CT scan report; 3 soft copies on external hard drive with media files and raw data; daily progress report. Cathodic protection measurements must be taken at specified intervals (12 m along pipelines, 50 m on piggyback line, 5 points on structures). Excavation dimensions must be at least 3 m deep, 3.6 m wide, 4 m long. Coordinates must be recorded in WGS84 format.

No pricing schedule, rates, bill of quantities, or payment schedule is provided in the document.

No pricing format, bonds, guarantees, payment terms, or financial capacity thresholds are stated in the document.

Personnel compliance: valid offshore survival certificate and full offshore medical certificate (in English) for all personnel. Non-South African personnel must have Section 11(2) visa with work authorization, approved before travel; PetroSA provides support letters. Alcohol and drug testing compliance: all personnel must pass breathalyser and random drug tests at PetroSA worksites. Vessel safety compliance: adhere to all policies and procedures of the DP2 Platform Supply Vessel Master. No CSD, tax, B-BBEE, CIDB, or CIPC requirements are stated in the document.

Health and safety: all personnel must have valid offshore survival certificates and full offshore medical certificates (in English, detailing medical tests). Non-South African personnel must have Section 11(2) visas with work authorization. Alcohol breathalyser tests are mandatory at all PetroSA worksites; random drug testing is conducted at access points. Intoxicated individuals will be denied access. Work is conducted from a DP2 Platform Supply Vessel; all vessel safety policies and regulations of the Vessel Master must be adhered to.

The scope of work is executed in two campaigns: Campaign 1 – mobilization of Work class ROV, ROV-mounted excavation tool, CT scan tool, and personnel to Mossel Bay; installation onto PetroSA DP2 vessel; offshore execution; demobilization. Campaign 2 – mobilization of survey team (surveyors, corrosion engineers, CAD operators, video data loggers, party chief) with tools to Mossel Bay; installation of survey spread onto PetroSA Inspection Class ROV; offshore execution; demobilization. Structures inspection includes CP stabs at five points, damage/anomaly checks, gas leak checks, debris within 2.5 m radius, coordinate and water depth recording.
