Marine, logistics and supply

Offshore construction, marine maintenance and the supply chain behind them

Four activities on one commercial registration: offshore platform construction (4100013), repair and maintenance of marine machinery and equipment (4773163), oilfield spare-parts trading (4773844) and heavy transportation of goods and equipment (4923020).

These sit together because on a real scope they arrive together. A platform module has to be fabricated, moved, installed and then maintained, and the parts for it have to be sourced to specification. Holding all four activities on Commercial Registration 48259 means one contract covers that sequence, instead of four vendors meeting at the quayside.

SECTION 03 — ACTIVITY 4100013 · 452000

Offshore platform construction, hook-up and commissioning support

Offshore platform construction for the extraction of oil or gas is a licensed activity on our commercial register — code 4100013 — alongside general contracting under 452000. Offshore work in Qatar is predominantly brownfield: modifications and tie-ins on live, producing installations where the permit-to-work regime, the shutdown window and the marine spread govern the programme as tightly as the engineering does.

  1. Structural steel fabrication Jacket and topside structural steel: rolling, cutting, fit-up and welding to AWS D1.1 and API RP 2A-WSD, node and tubular fabrication, deck sections and modules, boat landings, risers, J-tubes, caissons, conductor guides, walkways, handrails and gratings — with weld maps, NDT coverage to the project ITP, and dimensional control against the fabrication drawings.
  2. Blasting, coating and preservation Surface preparation and coating to NORSOK M-501, ISO 12944 or the client specification, splash-zone systems, thermal spray metallising where specified, and preservation of fabricated items through storage, transport and installation with a documented preservation register.
  3. Load-out, sea-fastening and marine spread support Load-out planning and execution at the quay, sea-fastening design support and installation, grillage and seafastening removal offshore, and coordination with the marine spread. Vessel certification — ISM, ISPS, class and ship sanitation certificates — attaches to the vessel owner, not to us; we work within those requirements and verify them before mobilisation.
  4. Brownfield modification on live installations Deck extensions and structural strengthening, clamp installation, retrofit risers and J-tubes, hot and cold tie-ins to live systems, temporary supports, and full reinstatement — executed under the operator's permit-to-work and job hazard analysis regime, with isolation, gas testing and fire watch coverage in place before any hot work.
  5. Hook-up and completion Piping spool installation and tie-ins, controlled bolt torquing and hydraulic tensioning with a joint-by-joint flange management register, cable pulling, glanding and termination, instrument installation and loop checking, and structural and architectural completion of modules.
  6. Mechanical completion and pre-commissioning System walkdowns against the P&IDs and line lists, mechanical completion dossier compilation, torque and tensioning records, cleanliness and preservation verification, flushing and air blowing, hydrostatic and pneumatic leak testing, drying, valve stroking and function testing, instrument calibration, and A/B punch-list management through to system handover.
  7. Offshore crew mobilisation and rotation discipline Nobody mobilises offshore in Qatar without valid T-BOSIET and H2S/BA training and a current fitness-to-work certificate, checked before travel rather than at the heliport. Crews are rostered against the field-break rules that apply at the location, confirmed in writing with the operator before mobilisation. Every offshore position is resourced with a named back-to-back so the roster does not depend on goodwill.
  8. HSE interface with the operator We work to the client's contract HSE plan and, where the operator's own corporate HSE standard for contracts is invoked, to that standard — preliminary contract HSE plan at tender stage covering mobilisation through demobilisation and site restoration, HSE officer appointment and client interview, pre-mobilisation equipment inspection, the pre-execution audit and work commencement certificate gate, and the monthly HSE performance return. Safety performance on a contract is reported to that operator through the monthly return; we publish no aggregate frequency rates, because a rate with no auditable exposure base behind it is a marketing number, not a safety record.

SECTION 04 — ACTIVITY 4773163

Marine machinery and equipment repair and maintenance

Repairing and maintaining machinery and marine equipment is licensed activity 4773163 on our commercial register. The work is condition-led: we measure before we quote, record what we find on teardown, and give you a written repair scope with clearances and tolerances against the OEM manual before parts are ordered.

  1. Diesel engine overhaul Main and auxiliary engine overhaul and component reconditioning — cylinder heads, liners, pistons, connecting rods, main and big-end bearings, crankshaft deflection measurement and journal assessment — with clearances recorded against the OEM manual and a signed measurement sheet issued with the job.
  2. Fuel injection and turbocharger work Fuel injection pump and injector overhaul, calibration and test-bench proving of opening pressure and spray pattern; turbocharger overhaul, cleaning, rotor balancing, bearing and seal renewal, and clearance verification on reassembly.
  3. Propulsion, shafting and gearboxes Marine gearbox and reduction-gear inspection and repair, gear tooth contact and backlash checks, stern tube and seal renewal, shaft alignment and chocking, propeller inspection and repair coordination, and steering gear overhaul.
  4. Rotating equipment and pumps Centrifugal and positive-displacement pump reconditioning, wear-ring and impeller renewal, mechanical seal and bearing replacement, laser shaft alignment, and performance verification on reinstatement. Deck machinery, winches and hydraulic systems overhauled and function tested.
  5. Auxiliary systems Heat exchangers and coolers cleaned, pressure tested and retubed; separators and purifiers overhauled; compressors and air systems serviced; electric motor removal, rewind coordination, insulation resistance and polarisation index testing before reinstatement.
  6. Condition monitoring and defect diagnosis Vibration analysis, infrared thermography, lube oil sampling and analysis, alignment and soft-foot checks, and performance trending — used to justify or defer an overhaul rather than to open machinery on a calendar date. Laboratory analysis is placed with an accredited laboratory and the report is issued under that laboratory's accreditation.
  7. Workshop and site capability Work is executed where the machinery is — at the client's berth, at the jetty, on board, or in workshop — and the location is fixed as part of the scope rather than assumed, because a strip-down alongside a working berth and a workshop overhaul are not the same job in access, in duration or in price.

SECTION 05 — ACTIVITY 4773844

Oilfield spare parts and material supply

Spare parts for the oil fields is licensed activity 4773844. What separates a usable supplier from a broker in this market is documentation: heat-number traceability, the right certificate type, and sour-service compliance where the line calls for it. Every enquiry is quoted against a specification rather than a description — the offer names the manufacturer, the certificate type the material will carry and the lead time, so what arrives can be checked against what was ordered.

Line pipe and tubeAPI 5L, ASTM A106, ASTM A312 and ASTM A333 low-temperature grades, ¼in to 72in NPS, in carbon, stainless, duplex, super duplex and alloy steel.
Pipe fittingsButt-weld, forged, socket-weld and branch fittings to ASME B16.9, ASME B16.11 and MSS SP-97, in matching carbon, stainless, duplex and alloy grades.

Electrical and hazardous-area itemsEx-rated cable glands, junction boxes and fittings, cable, lighting and hazardous-area accessories with the certification documentation attached.
Welding consumablesAWS-classified electrodes, wires and fluxes with batch certificates, supplied against the qualified WPS so the consumable matches the procedure rather than the price.
Structural steel and aluminiumSections and plate to EN 10025/10210 S275 and S355 and ASTM A36/A572; marine aluminium 5083-H116, 6061-T6 and 6063-T5 to EN 573 and ASTM B209.
PPE and site safety equipmentHard hats, harnesses and fall-arrest equipment, coveralls, gloves, respirators, gas detectors and safety signage to EN 397, ANSI Z89.1 and the client's site QHSE requirements.
Documentation supplied with every consignmentEN 10204 3.1 or 3.2 mill certificates, heat-number traceability to the item, NACE MR0175 / ISO 15156 compliance statements for sour service where specified, packing lists and certificates of origin. Material is supplied to the named specification from licensed manufacturers; API monogram and ASME code stamps belong to the manufacturer, not to Safari Qatar Services.

SECTION 06 — ACTIVITY 4923020

Heavy transport and project logistics

Heavy transportation of goods and equipment is licensed activity 4923020. In practice this is the movement of fabricated structures, vessels, skids, machinery and project cargo between the fabrication yard, Ras Laffan, Mesaieed, Hamad Port and the offshore load-out quay — where the route survey, the permit and the lifting study matter more than the truck.

  1. Project and abnormal load movements Movement of fabricated sections, pressure vessels, skid-mounted packages, transformers, engines and machinery, planned against a route survey covering axle loading, bridge and culvert clearances, overhead obstructions and turning radii, with the required road permits obtained before the move rather than on the day.
  2. Lifting studies and rigging plans Lift plans with calculated centre of gravity, sling angles and rated capacity checks, ground bearing pressure assessment, crane selection and positioning, and certified lifting gear with in-date test certificates. Every lift runs against a signed plan under a named supervisor, and where a contract calls for third-party certified lifting supervisors or riggers they are engaged for that scope — we do not represent certification we do not hold.
  3. Load-out, quayside handling and sea-fastening Coordination of load-out to barge or vessel, quayside handling, grillage placement, sea-fastening installation and removal, and lashing and securing calculations submitted for approval before sailing.
  4. Industrial city access and site delivery Delivery into Ras Laffan Industrial City and Mesaieed Industrial City with gate passes, driver inductions, vehicle inspection compliance and journey management to the operator's driving safety rules, including heat-stress and fatigue management provisions during the summer months.
  5. Cargo documentation and interface Packing lists, weight and dimension certificates, delivery notes reconciled to the material receiving voucher, and photographic condition records at loading and discharge, so a damage claim can be settled on evidence rather than argument.
  6. Fleet and equipment The transport and lifting spread is specified move by move — trailer configuration, prime mover and crane class chosen against the weight, the dimensions and the route survey rather than against whatever is standing idle. The quotation names the units proposed, their rated capacities and whether they are our own or contracted in, and each unit is inspected with its registration and test documentation checked before it mobilises.

Scopes and specifications

Send the specification and the location

For fabrication and installation we need the drawings and the load-out constraints. For maintenance, the equipment and its service history. For parts, the specification and the standard — API, ASME or ASTM — not just the description.
