In 2013, manager of the national gas distribution network Gasunie Transport Services (GTS), a subsidiary of N.V. Nederlandse Gasunie), started renovating parts of the regional gas distribution network.These include the gas receiving stations (GRSs), valve schedules and process control stations throughout the Netherlands.They require renovation in order to continue to meet the safety and distribution reliability standards in the future.This large-scale renovation programme is referred to as GNIP: Gasunie Network Improvement Programme.
As part of this programme, Gasunie contracted Visser & Smit Hanab to renovate the gas receiving station in Haarlem, the first of a series of six GRSs (Batch 2016) to be renovated by Visser & Smit Hanab. Project Haarlem is, in fact, a combined project, which also involved replacing incoming and outgoing GRS site pipelines. Activities were performed at the site of a former gas works.
Visser & Smit Hanab was responsible for various activities in relation to the GRS, which can be divided into four categories: temporary facilities, the skid, pipework, and renovation of the inlet and outlet schedules.
Examples of the work: prefabrication of support frames and gas control lines in our prefab workshop in Veendam; assembly of gas control lines and incoming and outgoing headers; repositioning the generator gas reducer; mounting E&I conduits, E&I cabling and tubing on the gas control lines and generator gas reducer.
Work started in May 2016 and was completed in August 2016. The other five GRSs in Batch 2016 will be taken into production in the period of September-December 2016.
