Technical Auditing, Industrial Lifting & Relocation Consultants
A significant amount of Lowther-Rolton’s appointments is the independent 3rd party Technical Audit (Technical Check and Safety Audit) of contractors’ load movement proposals. This particular service forms part of our Client’s risk management strategy by determining that operations can be completed safely with minimum risk to personnel and plant, thereby fulfilling our Client’s duty of care and due diligence obligations.
Acting on behalf of our Client we undertake a comprehensive review and analysis of contractors’ proposed transport and heavy lift (T&HL) procedures and perform independent design checks of the associated engineering aspects thereby addressing any interfaces. This continues to the operational locations to monitor the contractors’ compliance with accepted procedures, providing a continual project assurance role.
Our scrutiny of the technical proposals of contractors, designers and vendors, addressing any interfaces, ensures that all associated documentation are complimentary to each other and determines the viability of the proposed operations, when the pertinent information is accurately prepared.
Lowther-Rolton’s expertise, predominately from an engineering base, covers the following aspects;
- Construction techniques
- Land transportation
- Lifting by craneage, hydraulic lift/jacking systems, mast/tower lifting systems
- Load movement by sliding, rolling, launching methods
- Sea and inland waterway transportation
The reviews we perform embrace the subject of load movement of our Client’s equipment from vendor through to installation as an ‘umbrella’ review of the various operations, that determine the safety and stability of our Client’s equipment and asset, contractor’s plant and all personnel associated and/or in contact with the proposed load movements leaving ‘no stone unturned’.
Throughout our analysis we carefully consider the contingency plans that may be provided against a failure in performance, or supply, of equipment. Our objective is to assist in the development of operational planning, this being made as efficient as practicable, which has minimum risk of schedule overrun and maximises safety while complying with all relevant statutory regulations, engineering codes and good working practices.
Throughout our Technical Audit, our Directors, project managers, engineers, technicians and design staff are experienced professionals who have the technical knowledge and practical experience to integrate into our Client’s team, as necessary, representing and protecting their interests during the office desk study and operational environments throughout the execution of critical operations.
Experience has demonstrated that even with project checking procedures in place, deficiencies slip through due to various reasons such as misconceptions, assumptions, discontinuity and interfaces in/between companies/departments etc. Under our strict checking regime we continue to uncover a reasonable quantity of lifting attachments, transport stiffening and structural members that may not be designed correctly for the dynamic loading imposed amongst other issues.
Lowther-Rolton’s Technical Audit independent design checks, strength analyses and capacity assessments include, but are not limited to, the following:
- Ground Bearing Pressures (GBP) imposed by lifting equipment (such as cranes, gantries and lifting towers), transportation and temporary (staging) support of the lifted/transported item
- Temporary support foundations (such as spreader mats/plates) and more permanent foundation pads (such as concrete and/or reinforced concrete bases) for lifting equipment, transportation and temporary support (staging) of the lifted/transported items
- Transportation support beams/frames/saddles for cargo items (such as vessels or modules) being transported
- Transporter strength analyses, cargo and hydraulic stability and lashing/restraint assessment
- Support beams/frames/saddles for cargo items (such as vessels or modules) being shipped
- Sea forces, ship/barge deck strength and cargo lashing/restraint (sea-fastenings) assessment
- Lifting attachments (such as lifting lugs, trunnions and tailing frames/softeners) for items (such as vessels or modules) being tailed and/or lifted
- Local stress effects in vessel shell/module framing adjacent to lifting attachments
- Local and global stress effects in vessel shell/module framing under temporary support conditions during lifting, transport and/or shipping
- Trailer mounted tailing frame for items (such as vessels) being tailed
- Specialist demolition lifting attachments (such as temporary lifting lugs and push through “pipe” trunnions) and rigging items (such as spreader bars or lifting beams)
Lowther-Rolton provide the above as part of our Client’s risk management strategies.
Lowther-Rolton’s extensive experience and expertise has enabled us to assist not only our Client’s design team, but also those of the associated project management companies and contractors to understand and incorporate some of the design implications, not readily apparent in certain specific heavy-lift and transportation operations, into their extensive design procedures.
This includes the relative stiffness of modules compared to transport equipment, and the comparative flexibility of modules, or not, during lifting resulting in unequal load distribution and/or distribution significantly different to that modelled in the original design. Similarly the effects of rigging geometry utilising minimum lifting attachment locations on modules coupled with potentially non-statically determinate loading effects.
