Global Aqua Survey Ltd discusses marine engineering in Taiwan



Global Aqua Survey Ltd leads the way with Taiwan’s marine engineering industry and offshore projects

With the vast development of Taiwanese industry and high-tech industry over the next decade, the need for highly sophisticated marine engineering planning has also increased decisively. From industrial pipeline installations, near coastal industrial environment assessments, fiber optic cable deployments between countries to tank designs and many more. In response to these needs, Global Aqua Survey Ltd. (GAS) was established, with a backbone comprising the best marine research center in Taiwan NTUIO (Taiwan National University Institute of Oceanography) and the contribution of highly experienced professionals from the maritime industry.

Global Aqua Survey has a full line of sonar equipment, with the knowledge of how to use these instruments to maintain high quality accuracy: from single-beam bathymetric echosounder systems to multiple-beam echosounder systems, Side-scan sonar systems, from high-resolution subsurface profiles, to underwater video equipment.

In addition, Global Aqua Survey provides the most consistent service. From the preliminary planning of the project, they continue to provide surveying equipment, assist in system configuration, focus on data acquisition, data post-processing, mapping, integration and even to finish with the interpretation of the analyzed data.

Taiwan has been pushing for offshore wind power for a few years, and Global Aqua Survey Ltd. has undergone a far-reaching evolution as the way they operate and study needs to be more diverse. For example, in recent years, survey items have included the 3D Echo-scan underwater foundation, UXO survey (beach and seabed), high-resolution multi-channel spark seismic survey, sand wave migration measurements, CPT geotechnical sampling and vibracoring, aerial drone of intertidal zone topographic survey and ERT and MASW survey of shallow water zone.

To accomplish these tasks, the company’s employees must first follow a more appropriate professional training, and train abroad to obtain the GWO (Global Wind Organization) or BOSIET (Basic Offshore Safety Induction and Emergency Training) certificates. ). The first step for the company is to understand the international requirements for occupational safety standards. Therefore, in recent years, the company has worked with a Malaysian company named GEOLANTIC SDN. BHD., To teach GAS how to respond to the HSE (Health and Safety Executive) as a consultant and learn how to manage the various HSE documents required by employers.

In the field of equipment, the original survey instrument must be constantly maintained and updated. This fact, coupled with the rapid replacement of instruments, means that the company must be open to maintaining a lasting relationship with the equipment supplier. Therefore, a few years ago, GAS and SALT (Sea and Land Technologies Pte Ltd) of Singapore established a cooperative relationship. In addition, they also signed a memorandum of understanding with STR Asia Pacific Pte Ltd for a partnership; hoping that the company’s supply of precision instruments can be stable.

For GAS to explore the skill of surveying, this will must be supported by institutions outside of Taiwan to progress. For example, in order to sample a long sediment core, early cooperation with the US Alpine Ocean Seismic Survey Company was required to perform the 3 meter long core of the lake using a mini -vibrator. After that, GAS then worked with Alpine’s partner to sample 6-meter vibracores at depths of around 200 meters in the continental shelf area. In recent years, due to the need to develop offshore wind farms, GAS has worked with Australia, Neptune Marine Pacific Pte Ltd, signing a Memorandum of Understanding in 2019; in particular in the fields of UXO (Unexploded ordnance), CPT (cone penetrometer test), ROV (Remotely Operated Vehicle) and advice on inspection of foundations and submarine cables.

Developments in offshore wind, from environmental assessment, development and design to completion of operation and maintenance work, involve a wide variety of complex projects. It is not something that a marine research company like GAS can do on its own. GAS has been involved in many work projects over the years, gaining a lot of invaluable experience. However, it is also accepted that from now on, when the development of offshore wind in Taiwan finally started, GAS must be modest. GAS welcomes a transformation of operations and works with experienced foreign survey companies to develop valuable working relationships and thus create a stable and developed future.
