1.4 Implications European Council Directive 92/57/EEC

Subject directive has been or is being implemented in legislation of the European Country Members. For the Netherlands this is the Bouwprocesbesluit Arbeidsomstandighedenwet. Requirements as a result of this legislation for the Design/Engineering and Procurement phase of a project are as follows:

  • Ensure a notification is issued to the District Manager Labor Inspection for all projects exceeding 10 working days and 500 man-days of construction work. This document, which must be displayed at the site, is intended to communicate all relevant information to the authorities. This will enable them to monitor occupational health and safety and participate in improving the working conditions before work commences.
  • Appoint an SHWE Coordinator of the Planning (design) and construction phase. Normally within Company this would be the Project Manager.
  • Include in the project SHWE plan the hazards or work sequences so far identified which cannot be avoided and which will be a risk to the environment, to Health and Safety of construction workers and/or the occupants of or visitors to the construction site. Furthermore this SHWE plan shall address the mutual agreements concerning cooperation between Subcontractors and the provisions and preventive measures for Health and Safety taken.
  • Set-up and/or update the SHWE file (dossier) during the Planning (design) phase. This dossier normally contains technical specifications and any SHWE related measures taken during the design. The central project file shall be developed taking above requirements into consideration.

For implications during the construction phase refer to the SHWE plan construction/pre-commissioning.

It is imperative to verify “Clients” implementation of the directive. Specific Client SHWE plans may have been written. These shall be evaluated and Company’s SHWE plan should include/refer to Clients measures already taken.

1.5 SHWE Objectives

The SHWE objectives of the design, engineering, procurement, construction and pre-commissioning phases of the project are summarized below:

4.3.3 Fire Protection

A critical safety consideration for the overall plant design is to insure adequate fire protection. Extensive fire protection facilities have been anticipated and the basic requirements are contained in “reference document”. Company will ensure that these requirements, and the extended requirements as referenced therein, are implemented during the detailed design of the project.

4.3.4 Design and Constructability Reviews/Risk Analyses

Designs, constructability reviews, and construction execution plans will be developed, utilizing the model in the home office.

The design and constructability reviews shall result in a risk analysis to choose the lowest risk alternative, e.g.:

  • subassembly at grade with the potential of falling parts during lifting versus dressing activities at high elevations;
  • vendor supplied package units versus local assembly at site;
  • alternate sequences of construction events.

Furthermore design and constructability reviews shall focus on accessibility of equipment and other facilities not only during the operating phase but also during construction.

4.3.5 Features

The basic SHWE requirements of the “PN” project have been laid down in the “document name”.

These requirements need to be implemented during the detail design/engineering, procurement and construction phase of the project.

Ensuring safety in design and engineering shall include rigorous application of design and checking procedures. All internally produced documents such as Process Engineering Flow Schemes, equipment data/requisition sheets, calculations, specifications, diagrams and drawings shall be checked, reviewed and approved by authorized and properly qualified persons. Particular attention shall be paid to the correct implementation of all applicable standards, codes of practice and other design criteria as established in “document”. Conflicting requirements shall be resolved.

At the initial stages of the project a thorough review of the safety aspects of the technical documents contained in the “document” shall be conducted. Special attention shall be paid to the proper definition of area classifications, equipment layout with regard to safe distances, adequate accessibility for construction, operation and maintenance of the facilities, the location of the system isolation valves and adequate fire protection.

The SHWE aspects of the piping layout will be continuously reviewed as part of the total review as follows:

  1. Piping Studies
    Piping studies will be sent to the project task force for comments.
  2. Design Reviews
    Piping design reviews will be held on a regular basis.
  3. 3D CAD Model Reviews

Documents generated by third parties, such as Vendors, shall be examined and commented on to ensure that they comply with both specification and safety requirements. For potentially hazardous equipment, written operating and maintenance instructions shall be obtained from the manufacturers or the designers. The instructions concerning construction contained in drawings, specifications and other documents shall meet the safety requirements. If necessary, additional documentation will be prepared to advise the construction staff of special safety requirements.

Main SHWE design aspects are the following: “examples only”

  • “Plotplan of the PN project to provide an open and freely ventilated layout without congested areas”.
  • “Installation of fire-safe and fail-safe isolation valves at strategic locations to minimize releases at emergency situations (e.g. air operated fire safe ball valves, in case connections with large volumes of hydrocarbons, C4’s or lighter products or products above auto-ignition temperature exist)”.
  • “Selection of double mechanical seals or sealless pumps as appropriate for selected pumps”.
  • “Minimizing spill surface areas and confine spills by means of curbs, trenches or adequate sloping”.
  • “Application of fireproofing of column skirts”.
  • “Application of concrete piperacks in fire areas”.
  • “Application of extensive hazard detection by instrumentation systems, e.g. levels, pressures, temperatures, flowrates”.
  • “Application of gas, smoke and fire detectors throughout the PN project at suitable points”.
  • “Application of manual fire alarm call points where required”.
  • “Application of safety shower/eyewash stations”.
  • “Stuffing box type for valves in toxic service will be ‘environmental’ type”.

Design engineering shall also assure the following:

  • Adequate facilities shall be incorporated in the design to ensure that in case of an emergency the units can be shut down safely and in reasonably short time without damage to equipment and inventory. Emergencies to be taken into account are: power, steam or cooling water failure, instrument air failure, failure of vital equipment or fire.
  • The design should lead to cost effective operation and simplicity of maintenance.
  • Equipment shall be selected requiring a minimum of specialist/trained maintenance personnel. Where appropriate, state of the art diagnostic tools shall be incorporated.
  • The design shall include ergonomic considerations.
  • No prototype or unproven equipment shall be incorporated without a thorough study of the risks versus the rewards. “Client” should be advised if prototype equipment is utilized.
  • The design of equipment and the selection of construction materials shall be such as to accommodate all pressures, temperatures, stresses, corrosive conditions, etc., which may occur during erection and/or as a result of extreme operating conditions.
  • Safety of personnel and equipment is of paramount importance at all times and stages of operation and maintenance. The design shall reflect this requirement for all emergencies under minimum staff conditions. Night conditions shall be taken into account. In particular, safe starting, safe operation and safe shutdown of the plant shall be ensured.
  • Review the insulation requirements for personnel protection.
  • Plan and execute the engineering and procurement work to provide permanent ladders, stairs, platforms, and handrails at site as soon as they can be erected, to minimize the use of scaffolding and temporary access ladders.
  • Plan the optimum amount of work to be performed off-site in a controlled shop environment, where risks are lower than at a construction site.
  • Design all possible provisions into the plant to provide safer construction access; (e.g. use of hanging mobile scaffolds with handrails, toeboards and safety nets to catch dropped tools supported from twin l-beams at the bottom of the pipe rack).
  • Specify and purchase maximum off-site painting to reduce on-site paint storage requirements and to reduce emissions of volatile organic compounds during painting operation.
  • Schedule and execute engineering and procurement work to support rapid installation of all underground facilities before significant above ground erection work begins.
  • Adequately define all rigging and lifting requirements in advance, to ensure that all equipment and major subassemblies are purchased with the requisite lifting attachments.

4.4 Construction Safety

A separate SHWE Plan will be developed for construction during the engineering phase prior to the start of the site activities.

Company's SHWE Plan will be applied to avoid accidents and subsequent lost time injuries on the "PN" project. The uniform implementation and enforcement of the SHWE Plan will foster an attitude and commitment by all Company employees to abide by the health and safety standards and to analyze work plans for opportunities to reduce hazards and third party liability. The rigorous implementation of the SHWE Plan and the commitment of the team will have a direct benefit to the project in terms of reduced liability, no project delays due to lost time injuries, and reduced financial losses from damaged equipment and materials. All environmental field works, dealing with site investigation, waste and solid handling and usage of hazardous material will conform to this plan.

The SHWE Plan for construction is initially set-up as a framework document, to be updated to include site specific requirements and attachments prepared to cover special activities as required.

The SHWE Plan shall include but not be limited to the following activities/aspects.

  • induction of Company and Subcontractor employees;
  • site rules and safety regulations;
  • organization;
  • meetings and toolbox talks;
  • communications;
  • job hazards;
  • accident/incident reporting;
  • first aid, medical facilities, ambulance;
