Sheet A-03.3 · Pipeline and reservoir works

Laid once,
protected for years.

Oil and hydro-chemical pipelines, reservoirs and the corrosion control that decides how long either of them lasts. Led by a COREN-registered chemical engineer.

Discipline Chemical and civilPlant Owned, not hiredSince 1992
Specification

What this scope
actually includes.

ScopeLaying of oil and hydro-chemical pipelines, and construction of reservoirs and associated containment.
Corrosion controlSurface preparation, protective coating and cathodic protection specified for the medium carried and the ground it runs through.
ReservoirsReinforced concrete reservoirs and tank bases, including waterproofing and testing before commissioning.
PumpingInstallation of pumping arrangements, with 23 pumping machines held on our own plant register.
TestingPressure and integrity testing before a line is signed over, with results recorded rather than reported verbally.
ReinstatementRoads, houses and farmland disturbed along a route are made good under our standing local content policy.
Why corrosion is the job

Anyone can lay a pipe.

Corrosion decides the life of the line

Laying a pipe is the straightforward part. What determines whether it is still serviceable in fifteen years is how the steel was prepared, what it was coated with, and whether the protection suits the medium and the soil. That is a chemistry problem before it is a construction one.

The qualification behind it

Donkem’s work in this scope is led by a chemical engineer registered with the Council for the Regulation of Engineering in Nigeria, registration R.54,028. The registration is held by the engineer personally, as COREN registration always is.

Testing is not optional

A line is tested before it is handed over, and the result is written down. On our sites heavy plant is load-certified before it is operated and no schedule is accelerated at the cost of safety. The same discipline applies to a pressure test.

What a tender board checks

Cleared to bid.

Four things get asked before a pipeline contract is awarded to anybody. These are ours.

IncorporationRC 448870Registered with the Corporate Affairs Commission in 1992 as a private limited liability company.
SCUMLSC 081041Registered with the Special Control Unit against Money Laundering, which many operators require before a contract is awarded.
Tax clearanceCurrentHeld and current. The certificate itself is provided directly to a tender board on request rather than published here.
PlantOwned23 pumping machines, 7 compressors, 10 trucks and 10 site generators, on our own register rather than hired for the job.
On the project record. The 37 projects published on this site are buildings and civil works. The pipeline and reservoir record is not among them, and we would rather say so than pad this page. If you are tendering this scope, ask the office and the record and references will be sent to you directly.
What clients ask

Before they commit.

Is Donkem COREN registered?

A company is not COREN registered; engineers are. Donkem has a COREN-registered chemical engineer on the team, registration R.54,028, and this scope is led by him. Any contractor telling you the firm itself holds COREN registration is describing something that does not exist.

Where can I see completed pipeline work?

The project record published on this site covers buildings and civil works. The pipeline and reservoir record is not published here. If this is the scope you are tendering, ask the office and it will be provided directly, along with references.

Do you hire in plant for pipeline work?

No. The pumping machines, compressors, trucks and generators used on this scope are on Donkem’s own plant register. It is why a programme does not slip because a hire company was busy elsewhere.

What happens to land along the route?

It is made good. Roads, houses and farmland disturbed by our operations are reinstated, and compensation runs beyond cash to repairs, replacement, relief supplies and free treatment where it is needed.
