MSI completes data acquisition for Alexandroupolis INGS offshore Greece
Offshore staff
CAPE TOWN, South Africa – Metocean Services International (MSI) has completed a 520-day measurement program for Gastrade to support detailed design of the Alexandroupolis independent natural gas system (INGS) offshore Greece.
The Alexandroupolis INGS project consists of an LNG FSRU and a subsea and onshore gas transmission pipeline system. It is intended to provide a new natural gas delivery point to central and southeastern Europe.
Gastrade contracted MSI to collect a range of metocean data, including directional waves and current profiles at two locations (one at the proposed FSRU location and one nearshore at a pipeline crossing), as well as various meteorological parameters onshore.
Originally deployed in November 2017, the equipment was recovered in May 2019 with four interim site visits to check on equipment status, as well as to collect water samples for suspended sediment concentration and photograph biofouling for identification.
MSI deployed two AXYS TRIAXYS directional wave buoys, each fitted with an integrated Nortek Aquadopp current profiler, as well as a Campbell Scientific weather station onshore for measurement of winds, air pressure, air temperature, relative humidity, and rainfall. Data from the wave buoys and weather station was transmitted in real time to a website for the client to access.
Data collected from the project was provided to BMT to produce a metocean criteria report.
The Alexandroupolis INGS project is expected to begin commercial operations in 2022.
