LIQAL executed a design review and HAZOP analysis for the SHELL LNG bunkering facility in Teeside, UK. In this project ethylene carriers of among others SABIC (Saudi Arabian Basic Industries Corporation) are supplied with LNG. Because of LIQAL’s extensive knowledge and experience, we were able to execute this project within a short timeframe of four weeks. LIQAL’s recommendations resulted in a safe, secure and still operating bunkering system.
Sabic is one of the world’s largest petrochemicals manufacturers. In response to sulphur and nitrogen oxide emission regulations it chartered two LNG-fuelled vessels to operate between Teesport (UK) and the European continent. Unitrove, Shell’s UK partner deployed Schenk tank transport for the realisation of the bunkering station. LIQAL was hired to design and review modifications to an existing pump installation to solve the problems that arose after the initial installation. We were able to work around the existing constructions and manage the necessary adjustments to the bunkering installation. After our HAZOP analysis the bunkering installation became operational in May 2015 and it’s still being used for bunkering LNG today.
Arjan Stavast, Shell’s LNG business development manager, explains,
“We are very proud of achieving this milestone for LNG bunkering. The intensive collaboration between Shell, SABIC, Anthony Veder and contractors Schenk, Unitrove, PD Ports and LIQAL has enabled this success.”
The hazard and operability (HAZOP) study is the most commonly used process hazard analysis (PHA) method in the world today. It is the techniques commonly accepted by regulators with high safety requirements such as Shell. With a HAZOP we as LIQAL make sure that we do not only make a design for you, but also guarantee maximum quality and safety.
The objective of a HAZOP is to offer a structured approach to identify deviations from design intent and normal process conditions in a process installation. Process characteristics such as temperature, pressure and composition are combined with deviations such as more, less and reverse in order to identify operational and safety related problems in a structured way. If necessary, actions with responsible holders can be defined.
