TECH SPOTLIGHT
LINDAPTER’S TYPE AF CLAMPS WERE USED TO SECURE A SUBSEA PLATFORM
Atlantis Resources Limited is pioneering the development of tidal current power as the most reliable, economic and secure form of renewable energy. The structural design manager from Atlantis recently specified Lindapter clamping systems for securing a steel platform onto a tidal turbine foundation on the MeyGen project, the world’s most high profile tidal stream project.
Atlantis Resources was commissioned to design the electrical and mechanical infrastructure needed to tie several subsea measurement instruments into one system in order to monitor the marine environment. The instruments were hard-wired to the structure and therefore had to be installed with the foundation. The engineer designed a steel platform to hold the instrumentation sleds which weighed up to 4000kg. He sought a reliable connection for attaching this underwater platform to the Tidal Support Structure (TSS). The brief required a weld-free connection that would withstand the tidal forces and outlive the life of the instrumentation sled and platform in order to avoid any unnecessary subsea servicing.
The engineer evaluated several fixings for strength, longevity and reliability
before deciding Lindapter’s clamping systems were the best choice for the application. After contacting Lindapter’s technical team, the engineer was confident that the Type AF high slip resistant clamps in size M24 should be used to attach the steel platform back to the flange of the tidal turbine support structure. Further reassurance was provided by Lindapter’s range of independent technical approvals and over 80 years’ experience in designing and manufacturing steelwork connections.
Lindapter’s High Slp Resistance clamps provided lateral adjustability which allowed the installers to quickly align
the platform into position before tightening with standard hand tools.
The simple installation helped the contractor to save time and reduce labour costs on the project.

TRACEABLITY KEY BENEFIT OF DRILLING MUD FLUID ANALYSER IMPROVED AUDIT TRACEABILITY
Improved traceability of drilling fluid test results is provided by the MudChecker analyser, now available from Salunda Ltd.
The first handheld instrument of its type, this compact tester is used on a drill site, in a mud plant or a mud lab to provide rapid and consistent data about the mud properties that is critical to fast, safe and accurate drilling.
Advanced sensor technology avoids the need to wait several hours to complete a retort and titration mud check, saving time in the process, boosting the capacity
for repeated checks while enhancing productivity levels.
Using MudChecker, data is logged along with a date and time stamp electronically, avoiding any requirement for results to be recorded manually. This ensures that the data from every well and sample is recorded automatically after testing, enabling drilling engineers to show traceability in the event of an audit.
The data captured can be quickly up- loaded via a USB interface to a supporting software programme and can be exported
for formal record keeping and reporting.
MudChecker’s consistent and repeatable results can be quickly recalled to indicate percentage oil, solid and water volumes. It also records the oil/water ratio (OWR), oil/brine ratio (OBR) and water-phase salinity. Control of these parameters can be critical for kick detection, as well avoiding wellbore collapse, that might otherwise result in equipment loss or damage, and non-productive time (NPT).
