NNPC APPOINTS NETCO AS PROJECT MANAGEMENT CONSULTANT ON WRPC CARGO BERTH PROJECT

National Engineering and Technical Company (NETCO) was recently nominated by NNPC Management to review the tendering process, establish the amount on the bid documents and also provide project supervision to ensure cost and quality control on the repairs of the Warri Refinery and Petrochemical Company (WRPC) Cargo Jetties.

The project was necessitated following the attack and vandalism of the Trans Forcados Pipeline (TFP), operated by the Nigerian Petroleum Development Company (NPDC), several times by militants and oil thieves and is currently unavailable for transportation of Crude Oil and condensates.

Based on the aforementioned, the Management of Nigerian National Petroleum Corporation (NNPC) approved SEPLAT petroleum to undertake the repairs of the WRPC Cargo Jetties with pre-qualified contractor under the Seplat/NPDC JV in order to enhance the frequency of pumping fluid into small tankers at the WRPC jetties, thereby, potentially increasing the production.

The current unavailability of the TFP taken in conjunction with the frequency of outages in the recent past and a lot of locked-in production made it very expedient for SEPLAT Petroleum Development Company PLC to explore alternative evacuation routes for produced hydrocarbon fluids.

SEPLAT typically produces around 75,000 barrels per day (bpd) that is exported through the Trans Forcados export terminal. The alternative is the Warri Refining and Petrochemical Company Limited (WRPC), from where hydrocarbon fluids can be pumped to vessels shuttling to deep sea tankers offshore. The associated gas from the produced crude/condensate are routed to the national grid for the gas turbines used to generate electricity.

The shuttle vessels are scheduled due to limited berthing space at the refinery’s Loading Berth 1, which is also used for other activities of the Refinery.

NETCO’s Executive Director, Operations – Engr. M.Y. Yakubu and Manager, Project Controls –Engr. S.N. Isokariari attended the project kick off meeting held on January 19, 2017. NETCO’s Project team mobilized to site on January 31, 2017.

The Project is divided into two major parts, namely:

  • Refurbishment of Cargo Jetty Berth 1 – awarded to Dorig Technical Services International Ltd

  • Refurbishment of Cargo Jetty Berth 2 – awarded to Hensteel Engineering & Construction Services Limited.

 

The refurbishment of Cargo Jetty Berth 1 involves the procurement, fabrication and installation of two breast mooring dolphins for the berthing of the vessels with minor anchor and one buoy mooring dolphin for major anchorage of the vessels.

In the same vein, the refurbishment of Cargo Jetty Berth 2, consists of the procurement, fabrication and installation of two breast dolphins for berthing, two breast mooring dolphins for berthing of the vessels with minor anchor and one buoy mooring dolphin for major anchorage of the vessels.

Over Arup & Partners Nig Ltd. were commissioned by Seplat to conduct structural integrity assessment on the existing cargo jetties with a view to providing detailed designs and drawings that will be used to rectify any structural defect to guarantee the continued structural stability of the Jetty. Delattre Bezons Nigeria Limited (DBN) were mobilized to carry out structural remedial works on the deteriorated piles of the Jetties.

NETCO’s scope of services on the Project include but not limited to:

  • Review of the tendering process with a view to establishing the amount on the bid documents

  • Project Progress Monitoring and Cost Control

  • Premobilization inspection of equipment such as Tug Boats, Barges, Piling Rigs, Concrete Mixers, Concrete shooters, Excavators, Welding Machines e.t.c.

  • Review of  Purchase Orders, Engineering Design Drawings and associated documentation

  • Review of  Vessel characteristics, Bathymetric surveys, Cone Penetration tests and Geo-technical reports

  • Supervision of piling of 30” (750mmφ) steel casing pipes to the load bearing stratum for the breast dolphins and breast mooring dolphins.

  • Supervision of piling of 24” (600mmφ) steel casing pipes to the load bearing stratum for the buoy mooring dolphins.

  • Supervision of all welding activities such as double jointing of pipes and welding of the topsides.

  • Design checks on the pile capacity and depth of penetration

  • Quality control activities such as Pressure tests of the installed hydrant lines, review of Ultrasonic Test (UT) reports and Magnetic Particle Inspection (MPI) report

  • Supervision of replacement of 6” hydrant line around the Jetties.

  • Material inspections and Quality Control.

  • Supervision of painting of the hydrant lines

  • Hydrostatic tests on the hydrant lines

  • Supervision of installation of  cathodic protection systems

  • Supervision of concrete reinforcement of the buoy mooring dolphins

  • Supervision of Fabrication of Topsides, steel jackets & fenders.

     

In NETCO’s stride at encouraging local content capabilities, Deltec Engineering Limited and Arco Pipeline solution Nigeria Limited were engaged to support NETCO with expertise in Geotechnical Engineering and Quality Control. The geotechnical specialists reviewed the confirmatory soil reports and monitored the piling activities closely to ensure that piles were installed in line with the recommendations in the soil report.

On completion, each contractor will prepare and issue as built drawings for proper documentation. As at the time of this write-up, construction works was still on, with 84.39% and 47.58% completion achieved for Cargo Berth 1 and Cargo Berth 2, respectively. NETCO expended man-hours to date is 2,859 hrs as at 26th March 2017.

It is expected that the Project will be completed by end of the second quarter (Q2) of 2017.
