03 What we do

Engineering across the gas value chain.

From upstream surface facilities to LNG, city-gas distribution, and gas-to-products, delivered by engineers who design, build, and operate process plants.

01

Gas Processing & Surface Facilities

Conceptual and front-end engineering for gathering stations, gas plants, separation, and treatment, including non-conventional (MNK) surface facilities.

02

LNG & Mini-LNG

Feasibility and pre-FS for LNG and mini-LNG supply chains, regasification, and distribution to monetise gas in remote and island grids.

03

City Gas Distribution

FEED and detailed engineering design and construction (DEDC) for city-gas networks, pressure-reduction stations, and last-mile distribution.

04

Methanol & Petrochemicals

Pre-feasibility and engineering for methanol and petrochemical plants, including gas-feed evaluation and technology selection.

05

Pipeline & Transmission

Network design for oil, gas, and water gathering and transport, including routing, hydraulics, and design philosophies.

06

FEED, Basic & Detailed Engineering

Design basis, plot plans, equipment lists, and full engineering deliverables across gas and process facilities, from concept through detailed design.

How we work

From concept selection to detailed design.

A staged engineering approach that de-risks each investment decision, with deliverables matched to the maturity of the project.

Stage 01

Concept & Feasibility

  • Concept selection and technology screening for the facility and supply chain.
  • Gas-feed, demand, and logistics assessment.
  • Pre-FS and FS with CAPEX/OPEX and economic evaluation.
  • Design philosophies and high-level layouts.

WHY
Why TKL

Gas engineering grounded in operating reality.

01

Operator-grade insight

Our designs reflect how plants actually run, validated against facilities we have built, commissioned, and operated.

02

Full lifecycle, one partner

Concept, FEED, and detailed engineering in-house, removing hand-off risk between phases.

03

Gas value-chain depth

From upstream surface facilities to city-gas distribution and gas-to-products such as methanol.

04

Independent & trusted

Chosen by LEMIGAS, EMI, and national gas players for objective, buildable technical work.

Process facilities

Designed by engineers who have commissioned and run the plant.

Selected credentials

Delivered across the gas value chain.

Early Concept Development

Non-conventional (MNK) surface facilities

LEMIGAS / Pertamina Hulu Rokan · Rokan Working Area · 2024
