1 Israel Electric Corporation RFI - Request for Information Invitation to submit Technical & Commercial Information Including Price Estimation For Design and Manufacturing of Floating Security Barrier At the Israel Electric Company Maritime Domaine Contact: zeev gross zeev.gross@iec.co.il Deadline for sending information: 11 August

2 The Israel Electric Corporation (hereinafter: the "IEC") is the owner of five power plants located along the coast Haifa power station, Hadera power station, Tel Aviv power station, Ashdod power station and Ashkelon power station. 1. Introduction 1.1. Project Goals: IEC is seeking Information to provide security and safety measures for the inlet / outlet IEC seawater cooling pumps. Therefore, IEC is seeks a solution that will meet the following challenges: Preventing an intrusion of vessels into a designated and marked forbidden area Preventing a drifting swimmer from reaching the inlet pumps either if the attempt is from a vessel or and either from the land and swimming into the designated and marked prohibited areas Preventing the endangering of human lives in the outlet areas of the water pumps Reference threat: Small boats (up to 8.5 meters) and jet skis, each with a Maximum engine power of 110 Kw Kayaks, surfboards and SUPs (Stand Up Paddleboards) Swimmers General perception: To meet the challenges described above, IEC adopted a concept of security barriers in the entrances to the sites and safety barriers in the water inlet/outlet areas The outer security barriers at the entrances to the sites will inhibit intruding vessels and swimmers with a barrier enhanced with a structure to increase the freeboard (inhibit vaulting over the barrier) A safety barrier is to be located in closer proximity to the inlet ports to provide assistance to an inadvertent drifting swimmer from the adverse force from the pull of the inlet water pumps (line of demarcation) A safety barrier is to locate at a distance away from the outlets to establish a minimum distance that keeps a swimmer from the forces of the outlet water flows. 2

Scope Of Work: Manufacturer shall provide services to design, produce, transport and supervise the team of IEC installers to assemble and install the floating security and safety barriers at all five sites. For the construction phase, IEC shall provide all Sinkers, labor, and equipment necessary to install the floating barriers. The floating barrier shall meet the parameters stated below. These are the requirements on which the Manufacturer s bid will be evaluated. Work includes, but is not limited to the following: 2.1.

The IEC will secure the environmental permits required prior to construction. The IEC shall neither begin construction nor purchase boom or mooring materials until the 100% construction design is approved Design & supply two different types of linear floating barrier: A floating security barrier designed to impede lower level threats (see section 1.2.1, 1.2.2, 1.2.3) from entering designated restricted areas. This type of barrier will be designated as type "V" A floating safety barrier which will clearly delineate the boundaries of the designated restricted areas and will satisfy the requirement to assist any person who inadvertently is in the immediate areas of the inlet/out flows of water. (see section 1.2.2, 1.2.3). This type of barrier will be designated as type "N" or "U" (according to its location (inlet/outlet respectively) Environmental parameters: The floating barrier must be designed to withstand the following values and conditions: Vessel Barrier ("V") reiern eiitni ("N") Outlet Barrier )" U"( Remarks Other environmental conditions Wind Wave Tide Current ) stonk( ) stntek( ) stntek( ) stonk( The wind and current shall be assumed to act at normal incidence to the barrier. 2.
