DIESEL ENGINES:

Our mechanics have a lot of experience in the mechanical field engines of drilling & workover rigs. (CAT 3510 & CAT 3512, C18…)

The maintenance of the diesel engines is done according to the data sheets by applying the procedures of the manufacturer.

GENERATORS:

The maintenance of generators complies with international standards and compatible with:

• the recommendations of the International Electro-technical Commission IEC 34-1, (EN 60034).
• the recommendations of the International Standard Organization ISO 8528.
• European Community Directive 89/336 / EEC on Electromagnetic Compatibility (EMC) (Tractelec only).
• Directives of the European Communities 73/23 / EEC and 93/68 / EEC (Low Voltage Directive) (Tractelec and Gearlec).
• GEARLEC is CE marked under the Low Voltage Directive (LVD) as a component of a machine.
• TRACTELEC is CE marked for EMC, DBT (Low Voltage Directive) and MACHINE as a machine. A certificate of conformity can be provided upon request.

The hoisting system will be reviewed, inspected and repaired as follows:

• API RP 8B, API RP 4F, API RP 4G, ANSI et ISO 13534-2000…
• Spec 8A: Specification for Drilling and Production Hoisting Equipment.
• Spec SC: Specification for Drilling and Production Hoisting Equipment (PSL 1 and PSL 2).
• Spec 9A: Specification for Wire Rope.
• RP 9B: Recommended Practice on Application, Care, and Use of Wire Rope for Oil Field Service.

This international system outlines the requirements for inspection, maintenance and repair in accordance with international standards for a rig lifting system during operations to maintain the use of such equipment.
Equipment items according to international standards:

• crown-block sheaves and bearings;
• travelling blocks and hook blocks;
• mast
• substructure
• travelling block
• drilling line (cable de forage)
• block-to-hook adapters;
• connectors and link adapters;
• drilling hooks;
• tubing hooks and sucker-rod hooks;
• elevator links;
• casing elevators, tubing elevators, drill-pipe elevators and drill-collar elevators;
• sucker-rod elevators;
• rotary swivel-bail adapters;
• rotary swivels;
• power swivels;
• power subs;
• spiders, if capable of being used as elevators;
• dead-line tie-down/wireline anchors
• drill-string motion compensators;
• kelly spinners, if capable of being used as hoisting equipment;
• riser-running tool components, if capable of being used as hoisting equipment;
• wellhead-running tool components, if capable of being used as hoisting equipment;
• safety clamps, capable of being used as hoisting equipment

The circulating system consists of the equipment through which the drilling mud circulates. These are the mud tanks, the suction line, the slurry pumps, the discharge line, the drill pipe, the riser, the injection head, the square rod and the drill string before its back to the mud tanks.

The components of the circulation system are all subject to inspection, maintenance and repair according to the international standards (API, ISO and ASMI)

-Mud tanks

-Mud pumps

-Surcharging pumps

-HP lines

-Electric components

MUD PUMPS :

ROTARY HOSE

The rotation of the drill string is ensured by the rotation system.

 Currently, there are two types of systems. Their maintenance and revamping are following API, OSHA, ISO and ASMI rules:
The “Conventional” System: Kelly- Rotary Table –  …
The Top-Drive System: Electrical Element – Hydraulic Element – Mechanical Element.
All these components will be inspected, tested and renovated according to the international standards mentioned above.

The system consists of equipment that ODS provides genuine spare parts for renovation and testing.

Other equipment ( BOP) will be inspected and renovated by the manufacturer himself as per international standards.

All maintenance and revamping will be as per API RP 53 et RP 16
