We are proud to offer our clients a complete riser replacement and flare tip replacement service on flare structures for the petrochemical industry, including all structural engineering requirements.
We are heavy lifting equipment specialists and we operate worldwide and our portfolio of clients include the world’s leading oil and gas companies. Often working under tight time constraints, Zenith has a reputation for safety, efficiency and attention to detail.
In-house, we provide all of the specialist structural engineering, site management, project execution and extensive know-how.
Zenith can design and supply a comprehensive range of replacement rigging equipment including winch supply.
Zenith provide industry leading welding services that guarantee the longevity and durability of any structure. Our team comprises highly skilled professionals who possess the latest industry accreditations and certificates, meeting both British and American standards.
We take pride in our certified range of welding repair and installation services. Our skilled team work in demanding industrial environments such as oil, gas, power stations, cement plants, and petrochemical sectors, adhering to B31.1, BS EN and ASME standards. Welding repairs and installations are carried out during tight shutdown periods at both high and low levels.
Welder Procedure Qualification/Certification
Piping Installation
LOKRING®
Zenith is a trained and approved installer of the LOKRING® system and able to install:
The main advantage in using the LOKRING® method is that it eliminates the need for hot works at height in a refinery environment or offshore.
Zenith specialises in the installation of ground flares for the petrochemical industry. We provide a comprehensive installation service including all mechanical and welding requirements. We are proud to have constructed the largest ground flare in Europe.
We have all of the in-house expertise to offer our clients an unrivalled level of service.
As part of Zenith’s expanding portfolio of services, we are pleased to provide our clients with our PfCO CAA licensed UAV Inspection and Surveying Service carried out by our team of 7 qualified pilots.
We are able to generate 2D and 3D models from captured survey information and existing drawings. We can accurately determine revised capacities and assess the life extensions of existing structures and structural elements.
Decay, loss of section, material properties, geometry and change of use are a number of variables that can affect the performance and life span of any building or structure. This can all be modelled to represent a snapshot in time and assist with determining the structural integrity of existing assets.
A UAV inspection allows for a visual examination of structures providing photographic and video records. Following the survey, a comprehensive report is compiled by our dedicated team of Structural Engineers. UAV inspections allow engineers to identify and assess the general condition of the structure. This combined with Zenith’s hands on survey capability offers clients a full suite of inspection services.
Our UAS platforms can be tailored to suit the prospective operation, whether it be for extended flight duration, thermography, high definition photo or video imagery.
Visual Survey
Using our 30x optical zoom camera we can capture detailed close-up video and still imagery, even when the survey environment does not allow us to fly close to the subject, such as operational flare tips and chimneys. Ideal for condition surveys and defect identification on buildings and elevated structures.
Our high-resolution cameras are capable of 20Mp images and up to 5.2k definition video for high quality media for project highlights and marketing.
Thermographic Survey
Our thermal camera uses a specialized FLIR Tau 2 thermal sensor and a 4K visual camera along with image processors to render the results on a visual display. We have the capability to interrogate and interpret the survey data to identify temperature differentials and defects.
Orthomosaic and 3D Point Cloud
We can create high resolution orthomosaic images and 3D models of sites and structures by collecting a large number of individual overlapping photographs and processing them using specialised orthorectification software.
Topographic Survey and Volumetric Measurements
3D point clouds can be further developed and interrogated using specialist software to produce topographic (contour) maps and surfaces. Surfaces can be compared to enable volumetric calculations.
ROV Survey
Zenith also own an ROV for underwater inspections providing photo and video images.
Zenith provides a comprehensive guy wire service for structures such as flare stacks, steel chimneys and masts. In addition, we specify and supply complete guy wire requirements.
Our dedicated team of fully qualified inspection engineers also facilitate all on-site access requirements throughout the full length of the guy wires. Following the survey, all of the information obtained is fed back to our Structural Engineers who compile detailed inspection reports complete with recommendations.
Please refer to the list below for our full range of guy wire services.
Magnetic Inspection (LMA and LF)
Of particular note is our Magnetic Inspection (LMA and LF) service. Electromagnetic tests provide valuable additional information on the condition of wire ropes and are regarded as a useful addition to the visual inspection, particularly, where difficult access precludes a meaningful visual survey.
The permanent magnets induce a magnetic field around the rope, any defect within the wire rope creates a stray field, and this is detected and recorded on the data logger.
