EOSCA Software

EOSCA continues to support and develops software and modelling solutions for the oilfield chemical industry where these are most required.

CHARM

The CHARM model was developed jointly between EOSCA, operators and the regulators, and is currently being reviewed as part of a project proposed to OSPAR OIC in 2017.  To this end the CHARM Implementation Network (CIN) are meeting in October 2017 to agree a work programme for the development of the model.

NeCCS

NeCCS allows calculation of Hazard Quotients (HQ) and Risk Quotients (RQ) for substances and preparations used and discharged offshore, according to the algorithms contained within the Chemical Hazard Assessment and Risk Management (CHARM) Model.

EOSCA members have worked successfully with the previous CHARM Calculator for some years, but certain limitations of the software mean that it could not easily be updated for changes to the CHARM manual. In addition, users gave feedback on enhancements that they would like and NeCCS incorporates many new features and benefits including all the latest algorithms as included in CHARM User Guide Version 1.4.

NeCCS2

The EOSCA CHARM calculator is being revised and updated as part of an ongoing project, and a new version will be made available in due course.  The intention is that the new tool will be more device independent and allow a improved user interface, integration and reporting/exporting facilities.

EGEST

  • EGEST allows a first pass screening assessment (Tier 0 & Tier 1) of inhalation and dermal exposure together with environmental discharge assessment for substances with a view to help fulfilling the requirements of the REACH legislation.

Why are Exposure Scenarios required?

The EU Legislation for the Registration Evaluation, Authorisation and Restriction of Chemicals, REACH, is the main tool for regulating chemicals manufactured or imported in the EU.

For a given chemical from a given manufacturer/importer the REACH requirements depend upon:

  • Annual tonnage
  • Classification (ie: hazard data, whether a SVHC, classified as dangerous, etc)
  • Use – exemptions, derogations, requirements for intermediates, monomers, polymers, etc

As part of the Registration process it is necessary to compile a database of information in IUCLID and to carry out a Chemical Safety Assessment (CSA) and write a chemical safety report (CSR) for certain substance categories.

Risk assessments are required covering the life cycle of the substance.

The main elements of a risk assessment are a hazard assessment, an exposure assessment and a risk characterisation.

Various tools are involved in making an exposure assessment. It is normally necessary to communicate with downstream users to obtain the necessary information.

Mapping known uses to REACH Use Descriptors (SU, PC, PROC & AC codes) and Environmental Release Categories (ERC codes).

The EGEST report should help to map known offshore uses to use descriptors and environmental release codes. Relevant codes are included in the tool.

The EGEST Excel based tool should also help to perform generic risk assessments for the offshore use of oilfield chemicals. It does not cover earlier phases in the life cycle such as manufacture and formulation which should be covered elsewhere.
