EI 1587 Recommended practice for single cartridge filtration units for aviation fuel
This publication provides a specification for single cartridge filter housings (filter vessels with a single element mounting position) used primarily for the low pressure overwing fuelling of general aviation (GA) aircraft and helicopters.
It also provides a guide for users on the types of aviation fuel filter cartridge that are available for such housings, including what they are designed to do and their key differences to help with equipment selection. It provides further recommendations for purchasers/users on equipment installation and operation.
This publication is intended to help those involved in the design, manufacture, installation and operation of single cartridge filtration units or aviation fuelling facilities that incorporate single cartridge filtration units.

3581 Guidance on co-location of battery energy storage system (BESS) with power generation plant
This publication is free of charge. Register/log in to download.
Power generation systems are decarbonising and so the need for electrical energy storage to manage grid demand and frequency is increasing. Battery energy storage systems (BESSs) have demonstrated their ability to provide grid-scale electrical energy storage and support grid frequency stability control. Consequently, many businesses and organisations are considering if BESS technology can add value to their existing operations through co-locating – for example, with onshore wind and solar, and other power generating plant.
The information contained in this publication is intended to give the reader a high-level understanding of the benefits, risks and interactions a BESS may bring when co-located with other power generation systems. This will enable the reader to progress into the concept and supplier selection stage of a co-located BESS project.
This guidance is for those who own or operate grid scale (which is typically over 1 megawatt (MW)) power generation plant and are considering co-locating BESS on to their existing site.
The guidance covers various topics at a high level, including:
- battery chemistry types;
- functionality of BESS, including arbitrage frequency response, renewable integration, etc.;
- key legislation, regulations and codes of practice;
- stakeholders who should be considered when co-locating BESSs;
- BESS risks including battery fire, explosion, smoke, electrical hazards, and
- environmental impacts of co-locating.

3462 Wind Turbine Safety Rules Procedure 5: Temporary application of an alternative safe systems of work
The Wind Turbine Safety Rules (WTSRs) are a model set of Safety Rules and procedures to help formalise a Safe System of Work (SSoW) to manage the significant risks associated with a wind turbine, both onshore and offshore. They have been developed by wind farm owners and operators for the purpose of achieving both general safety and safety from the system – a process that safeguards persons from the mechanical plant and LV apparatus and the associated system derived hazards.
The general direction of the Rules will be set by SafetyOn together with members of the G+ Global Offshore Wind Health and Safety Organisation.
This document is free to all registered members of this site. Please login to download.
