Method Statement (MOS) Preparation Services
Professional method of statement preparation for construction, installation, maintenance, and commissioning activities — supporting permit-to-work and contractor submittal requirements across Saudi Arabia.
SLETEC Engineering prepares Method of Statement (MOS) documents for construction, installation, maintenance, and commissioning activities on oil & gas, petrochemical, and industrial projects across Saudi Arabia. Our method statements are structured technical documents that describe, step-by-step, how a specific activity will be planned and executed — covering personnel and equipment requirements, sequencing, HSE hazards and controls, permit-to-work requirements, and quality hold points.
Clients require method statements as part of permit-to-work packages, contractor pre-qualification submissions, and engineering technical submittals for Saudi Aramco, SABIC, and other major operators. SLETEC method statements are written by engineers with direct site experience, ensuring the described methodology is practical, technically accurate, and meets the expectations of the client's HSE and engineering review teams.
Our MOS preparation scope covers structural steel erection, pressure vessel and equipment installation, pipe spool installation and testing, tank erection and hydrotest, rotating equipment alignment and installation, scaffold erection, hot tapping and in-service connection operations, and maintenance activities on static and rotating equipment. Each method statement is reviewed internally for technical accuracy and HSE completeness before client submission.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Frequently Asked Questions
What is a Method of Statement (MOS) in oil & gas projects in Saudi Arabia?
A Method of Statement (MOS), also called a Method Statement, is a structured technical document that describes step-by-step how a specific construction, installation, maintenance, or commissioning activity will be safely and correctly carried out. In Saudi Aramco and SABIC projects, MOS documents are required for permit-to-work approval, subcontractor pre-qualification, and contractor technical submittals.
What types of method statements does SLETEC prepare?
SLETEC prepares method statements for structural steel erection, equipment installation and setting, pipe spool installation and hydrostatic testing, pressure vessel installation and commissioning, tank erection and hydrotest, hot tapping and stopple operations, maintenance activities on rotating equipment, and scaffold erection and dismantling.
Does SLETEC's MOS preparation include HSE and risk assessment content?
Yes. SLETEC method statements include a hazard identification and risk assessment section, referencing project HSE standards and identifying controls, PPE requirements, permit-to-work types required, isolation requirements, and emergency response references. This makes our MOS documents ready for HSE review without requiring separate supplements.
How quickly can SLETEC produce a method statement for a construction activity in KSA?
Standard single-activity method statements typically take 2-5 business days to prepare, depending on the complexity of the operation and availability of reference documents (scope drawings, equipment datasheets, project HSE plan). Complex multi-phase MOS documents for major lifts or commissioning activities are scoped individually.
