What should we build?
Duty, fuel, site conditions, unit size, fleet composition and time-to-power are tested before a platform is selected.
Independent gas-engine technical advisory
Gas-engine expertise for power developers and asset owners.
Equipment selection, new-versus-pre-owned strategy, lifecycle economics, reliability engineering and owner-side technical due diligence for distributed and behind-the-meter power projects.
Decide what to build, what to buy and what to reject before capital is committed.

External competence / owner-side
The gas-engine competence layer your project team needs.
K4 supports developers who understand power projects but need deeper gas-engine expertise before locking the technology, equipment fleet and operating model.
What should we buy?
New, used, rebuilt and relocated options are compared on evidence, remaining lifecycle and whole-life exposure.
Can the fleet deliver the required MW?
Scheduled maintenance, overhaul rotation, forced outages, redundancy and common-mode risks are treated realistically.
Core gas-engine capabilities
Three decisions that shape the project lifecycle.
Start with the owner decision, test the evidence behind the equipment, then build a realistic operating and maintenance model.
CAPABILITY / 01
Gas Engine Strategy & Selection
Technology and platform selection, fleet sizing, new versus used options, fuel fit, lifecycle economics and time-to-power trade-offs.
CAPABILITY / 02Used Equipment Due Diligence
Verify identity, configuration, condition, operating history, remaining lifecycle and transaction risk before purchase.
CAPABILITY / 03Lifecycle & Reliability
Maintenance strategy, overhaul exposure, redundancy, critical spares and dependable fleet capacity over the operating life.
Power developers / data centers / industrial BTM
Building a power project without deep in-house gas-engine expertise?
K4 can act as the independent advisor on the owner or developer side — from early technology choices through fleet verification and operating readiness.

AI and data-center power / zero stage
Choose the power architecture and equipment before major CAPEX.
K4 helps owners and developers test on-site gas-power architecture, unit size, fleet redundancy, fuel requirements and new-versus-used equipment as one owner-side decision.

Used equipment / asset and fleet DD
A running engine is not automatically a suitable fleet asset.
K4 tests whether the exact machine — and the fleet around it — can support the intended output and duty over its remaining lifecycle.

- 02Operating and lifecycle historyHours, controller records, repairs, replacements and overhaul events reconciled.
- 03Condition and preservationBorescope, corrosion, storage, leaks, fluids and physical evidence.

Decision boundary: conclusions are limited by the evidence available. Unresolved items remain visible rather than being converted into unsupported guarantees.
New / Evidence-based technical due diligence
Buying or investing in a gas engine?
Before price becomes the decision, understand the engine's actual condition, maintenance history, overhaul exposure, fuel fit and lifecycle cost. K4 provides an evidence-based written conclusion for buyers, investors and lenders.
Screen the opportunity
Remote review of the available offer and documents, focused on material gaps, red flags and the next evidence worth requesting.
Test the investment case
Deeper technical due diligence covering condition evidence, maintenance and overhaul exposure, configuration, fuel, scope and lifecycle implications.
Verify the asset in person
Inspection scope is defined around the asset, location and decision. Travel, tests and specialist inputs are agreed before engagement.
Evidence, not marketing
Methods connected to field evidence.
The advisory framework is grounded in published cases, operating records and transparent lifecycle analysis. Each source states what is verified, reported or inferred.

Read the framework →Owner's Engineering / local execution
Local contractors execute. We protect the client's decision.
The client contracts the selected local contractor directly. K4-Technology remains independent on the client side — defining the result, testing the bid and verifying delivery.
Engagement model / client-sideDefine → Select → Verify
Decision / 01
Define the result
Requirements, interfaces, economics, risk allocation and acceptance criteria are fixed before the tender.
Market / 02
Qualify local execution
Contractors are sourced and assessed; offers are normalized so price, exclusions and technical risk are comparable.
Delivery / 03
Verify every gate
Design reviews, factory and site tests, milestones, commissioning evidence and handover are checked against the brief.
Advisory firstK4's core role is independent owner-side technical advisory. K4 may also undertake separate sourcing, engineering, commissioning support, service or supply scopes. K4 does not claim independent due diligence where it receives a sales commission, supplier-side fee or other commercial benefit from the asset, supplier or contractor being assessed. Any such commercial role is disclosed before engagement. Owner-side advisory, engineering and commissioning support may continue across the same project where K4 remains engaged solely on the client's side.
Engagement levels
Start small. Add depth only when the evidence supports it.
Is there a project?
A concise decision memo with key assumptions, indicative CAPEX/OPEX, red flags and the next information required.
Is it bankable?
A transparent technical and economic model with scenarios, lifecycle costs, equipment concept and implementation strategy.
Is it being delivered correctly?
Targeted owner's engineering through tendering, design review, testing, commissioning and acceptance.

K4 engineering group
Operating experience behind evidence-based advice.
KIV-Technology d.o.o. in Belgrade is the international contracting entity of the K4 engineering group. The group's operating track record — 16 gas engine power plants totaling approximately 25 MW — is the practical foundation for our international advisory work.
We are independent of engine manufacturers and execution contractors. Our recommendations are informed by installation, commissioning, maintenance, overhaul work and live service contracts, but our international role starts on the client's side: analysis, due diligence and technical control.
Clear answers
What clients and technical reviewers ask first.
What decisions can K4-Technology support?
Which gas-engine platform fits the duty, whether new or pre-owned equipment is rational, how lifecycle economics compare, what reliability architecture is required and which supplier claims need verification before capital is committed.
Does K4-Technology act as the EPC contractor?
Our default model is client-side advisory. The client contracts a qualified local execution contractor directly; we define requirements, evaluate bids and verify delivery. Any broader scope is agreed separately.
What inputs are needed for a rapid project screen?
Useful starting inputs are a gas analysis, site and load data, utility constraints, supplier quotations and any available equipment or project documents.
What does pre-owned genset due diligence deliver?
A written engineering report with photo and video evidence, condition findings, residual-life assessment, restoration budget and a fair-market-value opinion.
