By Richard Hepworth, President of Trelleborg’s marine systems operation
Trelleborg’s marine systems operation will showcase its Emergency Shutdown Link (ESL) technology for the Oil and Chemical Tanker industry at The 2017 Tanker Shipping & Trade Conference (stand 1, 14 – 15 November) in London, UK.
The Tanker Shipping and Trade Conference and Awards is a two day event that covers the commercial, operational and technical issues impacting the crude, product and chemical tanker trades.
Linked ship/shore ESD systems have long been present in LNG and LPG transfer operations as a key safety feature. Similar safety issues also exist between ship and shore in the transfer of oil and chemicals, however there has been no industry standard that has been available to guide developments.
The ESL is designed to meet the Oil Companies International Marine Forum’s (OCIMF) recommendations for linked Ship/Shore Emergency Shutdown (ESD) Systems for oil and chemical tankers. Introduced in April 2017 and published in conjunction with the Chemical Distribution Institute, the guideline provides a welcome step in the evolution of safety and regulations in the oil and chemical transfer arena that we hope, in time, it will be included in project requirements. We look forward to discussing our compliant ESL at the conference and hearing the latest experiences and opinions of those across the market.
The recommendations suggest best practice for connections between ship and terminal ESD systems through the implementation of a linked ESD system, so that ESD activation by either the terminal or ship will stop cargo transfer operations. They specify an electrical umbilical incorporating 5-pin twist connectors, for universal adoption. Minimum initiators for an ESD are a manual trip or auto trip on power fail, with optional initiators including fire detection, tank overfill, loss of containment and activation of loading arm release.
Trelleborg, alongside other suppliers, advised the OCIMF on the systems guidelines in the document. The Trelleborg ESL system features an industry standard 5-pin twist connector along with intrinsically safe circuitry, suitable for hazardous area applications, ensuring galvanic isolation between ship and shore. A simple test function is also provided.
