Construction contract Embsen compressor station and metering station
Construction of the Gas Technical Installations, electrical installation and civil works for the new compressor station and metering station at Embsen (near Achim) Germany (short: ACCS and ACMS). Fully in accordance with the German regulations, DVGW requirements, the Gasunie Deutschland technical standards and Pipeline Integrity management system (PIMS procedures).
GASUNIE intends to erect a new gas compressor station as well as a pressure regulating and metering station near Embsen. The stations are located southeast of Bremen along the highway A27. The new compressor station shall increase the transport capacity of H-Gas in West-East-Direction (existing pipelines) and the new NEL pipeline system, currently under construction. For control and metering of gas from / to the NEL a new pressure regulating and metering station is also required.
The area of the compressor station comprises about 4,3 ha, for the metering station around 1.3 ha are required. The new stations will be connected (tie-ins) 2 times to ETL 51, to the NEL and the adjacent metering system of NETRA in VDS Achim.
The compressor station (CS Embsen) consists of inlet filter separators, two gas driven compressors trains inclusive dedicated gas coolers and respective suction and discharge headers. Furthermore utility systems exist as fuel gas system for gas turbines and station heating, condensate collection system, emergency diesel generator and instrument air system. The pipe headers and compressor runs can be individually vented through dedicated vent stacks. The station is designed to allow for compression up to 100barg.
The metering station (MCS Embsen) consists of inlet 2 filter separators, 3 parallel metering runs inclusive fiscal metering and gas preheater, fuel gas system and a hot water system. The whole station piping is designed for 100 barg.
The stations are designed for unmanned, fully automatic, permanent operation. Hence separate control systems for both station will be provided.
In advance already End of 2012 first site works will be started by GU as:
— access street to the construction area,
— partly installation of the temporary construction area,
— pre-construction work e.g. field works, piling at the metering station,
— construction of a single connection line between NEL and existing NETRA metering station at VDS Achim.
The main contractor is responsible for takeover, continue and finalise previous installations.
Due to the local situation special attention needs to be taken for ground water handling during construction. Piling for main buildings and equipment foundations is required.
All required construction works shall be done by one Main Contractor (MCC). It includes – but not limited to:
— construction and commissioning of compressor and metering station incl. hand over to operation,
— erection of following buildings:
—— compressor buildings (2 units),
—— station control building,
—— utility building,
—— fuel gas building,
—— metering building,
—— boiler building incl fuel gas room,
—— electrical building,
— installation of pipework and mechanical components,
— electrical and instrumentation works,
— civil and HVAC subsystems.
Main mechanical equipment, pipe material valves for PN 100 as well as most of utility systems will be supplied by Gasunie and provided to Main Contractor.
Earliest construction shall start March 2012 whereas start of commissioning for both stations is planned for august 2014. RFO date is 26.2.2015.
