Basic Engineering Review and Detailed Engineering and Design of Instrumentation Scope

The customer is a liquefied natural gas (LNG) receiving terminal that is built at the Port of Hamina, Finland. The Hamina import terminal project forms part of Finland’s wider plan to establish a network of medium-scale LNG terminals to provide LNG for ship bunkering and increase gas supply within the country. A 30,000m³ LNG storage tank is built during the first phase of development along with other infrastructure such as a regasification plant, gas metering facility, boil-off gas handling (BOG) system and loading / unloading facilities, as well as electrical and control systems.

Main contractor received a turnkey engineering, procurement, and construction (EPC) contract for the Hamina terminal in October 2017. The scope of the deal includes site filling, soil refurbishment, civil works and the construction of full containment storage tank and infrastructure facilities.

The scope of GIZIL as an engineering subcontractor is basic engineering review and detailed engineering activities for

  • Electrical Basic Engineering review for general specifications for MV switchgears, power transformers, diesel generators, LV switchgear, MCCs, lighting, grounding, lightning, cathodic protection, lcs (local control station), MV and LV cables and control cables
  • Electrical substation layout
  • Typical installation drawings (power, earthing, lighting)
  • Instrumentation Basic Engineering review for specification for instrumentation, control & safety system, telecommunication and plant security system, preliminary substation control room, instrumentation & telecom room arrangements (markup)
