LowtherRolton

THE COMPANY: Lowther-Rolton was formed in 1987 to provide Clients with an independent engineering service in construction technology by concentrating on the construction techniques, planning, design and 3rd

party Technical Auditing to enhance safe construction and engineering activities, fundamental to a project.

Our company, as professional consultants, uniquely specialises in engineering the load movement of all types of pre-assembled/pre-cast structures in the fields of petrochemical, energy, nuclear and fossil power, bridge construction and specialist structures.

The expertise applied by our Directors and staff originates from the wealth of experience gained previously as contractors and designers. Our team of highly experienced engineers cover the disciplines of civil and structural engineering, providing a full range of design services. We offer our expertise and services worldwide together with the provision of suitably qualified and experienced staff to integrate into a Client’s project team.

We pride ourselves on the ability to design load movement schemes (transportation and lifting) and permanent or temporary structures that are innovative, practical, economic and safe to construct. Our ‘hands-on’ experience of construction equipment for load movement is comprehensive and unique. Thereby the company provides a professional engineering based service as an independent alternative to load movement contractors and suppliers.

The company has been appointed to numerous major construction projects around the world. Our head office is in the UK with regional offices globally located in Australia, UAE and USA.

We also offer marine engineering and Marine Warranty services for movement of loads by sea and/or inland waterways, together with HSE services, as consultants through our expanded network. We ensure a dedicated, seamless, high quality and comprehensive on-shore and off-shore engineering service that is second to none.

CONSTRUCTION PLANNING:

Our staff are highly experienced in their chosen fields and our early involvement as part of a project planning team can assist to optimise:

Constructability

Contingencies against schedule overrun

Economy

Flexibility

Modularisation

Safety

We offer technical advice to our Client and their design/construction team on construction techniques and specifically the engineering supporting modularisation. To fully realise the cost and time benefits of this modern and proven technique of construction it is imperative that experienced advice on the issues affecting design, assembly, transportation and installation of Modules and Vessels is sought at an early stage. Our advice, being independent, shall consider a range of equipment options which is not influenced by contractors’ specific preference.

TECHNICAL AUDITING:

A significant amount of our work is the 3rd party independent Technical Auditing of contractors’load movement proposals. This particular service is a risk management strategy for the Client,determining that operations can be completed safely with minimum risk to personnel and plant. Acting on behalf of our Client we undertake a comprehensive analysis of contractors’ proposed procedures, 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.

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.

Acai Project - Camaçari Petrochemical Complex, Brazil Client: BASF

Contracted by BASF/Worley Parsons as independent Technical Auditors and advisors for the movement of a 65m long Condensation Tower for BASF’s Acai Project at Camaçari, Bahia, Brazil. The total weight of the transport was 730Te. The move was particularly challenging as the 50km delivery route featured numerous overhead obstructions, width restrictions, gradients, junctions and weak bridges. Due to imposed axle weight restrictions while crossing bridges, the transport operation required in total 60 transporter axles (120 suspension units), together with turntables, which were required for manoeuvrability. Lowther-Rolton undertook a Technical Audit of the route surveys and transportation engineering aspects together with site attendance, providing oversight during the road transportation.

NIPSCO Dry FGD Retrofit Project - Indiana, USA Client: NIPSCO/Graycor Industrial Contractors Inc

BP Whiting Refinery Modernization Project - Whiting, Indiana, USA Client: BP Products North America Inc

Contracted to BP as independent 3rd party Technical Auditors and advisors for all transportation and heavy lifting proposals together with the associated engineering aspects, including attendance at the operationallocations. This ensured compliance with the accepted procedures and requirements of the transportationand lifting studies were implemented prior to the load movement, with constant monitoring during the operations. Our role comprised of independent 3rd party assurance (Technical Audit) for the loading/transhipment/off-loading, transportation and installation of approximately 1,000 process equipment items, up to 950Te, Modules, up to 560Te and included Pump Foundation Modules complete with Pumps.

Carson Refinery Coker Power and DCS Project - California, USAClient: Tesoro Refining & Marketing Company Ltd

When a US West Coast Refinery carried out an upgrade to their Coker Unit, the required electrical building had to be constructed using the modular approach due to the congested nature of the existing Refinery Unit. Although each of the four sections, which comprised the two story building,were each relatively light, weighing approximately 28Te, the characteristics of the lift over live services and existing buildings determined that a comprehensive in depth study was required. Fortunately the owner’s project team identified this requirement early in the project and Lowther-Rolton were contracted to provide 3rd party Technical Audit services. Over a 12 month period Refinery, engineering and contractor personnel together with Lowther-Rolton ensured that the installation plan was thoroughly and accurately engineered, planned and risk assessed, leading to a flawless lift and installation operation using a 400Te capacity hydraulic mobile crane.

BP Zhuhai PTA #2 and PTA #3 Projects - Zhuhai, China Client: BP Chemicals Ltd

Independent Technical Audit, including site attendance, for the transportation and installation of 21 Process Vessels and Modules.

The heaviest item to be installed at BP Zhuhai was the CT232 Dehydration Tower, weighing 655Te and a height of approximately 58.4m. Prior to installation, the Tower was tailed from the horizontal to the vertical using two cranes,

Terex-Demag CC8800-1 main crane and Terex-Demag CC5800 tail crane. Once the Tower reached vertical, the tail crane was released and the main crane, configured with 600Te of superlift counterweight,completed the installation. During the installation, the Tower was required to be carefully manoeuvred above and between existing structures with minimal clearances on 3 sides of the Tower foundations.

Prior to the installation of Silo Cone CF610, weighing 352Te, the Silo Cone was required to be rotatedvertically through 180° using two cranes, Sany SCC16000 main crane and Terex-Demag CC2800 tail crane. Once rotated to vertical, the tail crane was released and the main crane, configured with 560Te of superlift counterweight, completed the installation into the Silo structure, hoisting the Silo Cone to a height of approximately 98m.

Finite Element Modelling to Determine Shell Stresses Around Lifting Attachments

We routinely use Finite Element (FE) modelling to determine shell stresses around lifting attachments where the shell geometry or lifting attachment details fall outside the design provisions of the pressure Vesselcodes. In the following example a 125Te pressure Vessel is to be lifted by trunnions, which are welded to the shell via compensation plates close to the torispherical end.

In-house Computer Programs for the Analysis of Transportation and Heavy Lifting Operations

We have developed a specialist range of in-house programs for the detailed analysis of transportation and lifting operations. These include programs for the analysis of transportation by trailer and ship, the tailing of petrochemical Columns and the dynamic behaviour of load movement. These programs are used to check stability during the operation and provide design forces for loaded structural elements.
