INGEMATION ENGINEERING carried out in the last weeks, four Factory Acceptance Tests (FAT) for the Dolwin 6 project
In total, eleven safety, control and distribution cabinets have been tested.
In the last weeks of January and February, we carried out four Factory Acceptance Tests (FAT) for the Dolwin 6 project; an HVDC type offshore substation for the German North Sea, developed and built by Dragados Offshore.
Each test has been carried out in the presence of Dragados’ team of representatives, the classification society, and the end client, verifying the correct operation and compliance with the specification of each piece of equipment, following all the official protocols and regulations. These include alarm systems, fire pump control systems, safety and control panels and distribution panels.
All the panels developed and tested are scheduled to be delivered next Friday, 12th February.
The tests carried out are as follows:
Signal Light Column
Acoustic/Light Alarm System (for noisy environments), consisting of a control panel with nine columns according to IMO standards. Its main function is to make it easier for personnel working in engine rooms and in noisy or difficult environments to perceive alarms and safety warnings.
Seawater pump control panels.
These are four panels for starting and controlling seawater suction motor pumps, which are critical for the cooling systems of the plant’s high-voltage equipment. They are large pumps; almost 200 kW each.
Fire-fighting pump control panel systems. These are two panels that form a redundant pair for the control of fire-fighting pumps (two boosters and two jockeys). The system must also supply the fire-fighting water and the foam generation system. They allow remote monitoring and testing of the key elements.
UPS distribution panels
The purpose of these switchboards is to distribute and protect all the platform’s essential circuits that must be supplied from the uninterruptible power supply unit, in order to guarantee their availability in emergency situations. The system is made up of four switchboards (two redundant pairs), capable of supplying more than 440kW of electrical power. Distribution is carried out in both direct and alternating voltage.
