Petrofac has awarded Malaysia Marine and Heavy Engineering (MMHE) a second subcontract to build an offshore substation (OSS) for TenneT’s 2GW programme in the Netherlands.
MMHE will build the high voltage direct current (HVDC) platform’s topside and jacket, which is called the Nederwiek 1.
The topside will weigh approximately 30,000 tonnes (including equipment) and the jacket will weigh approximately 10,000 tonnes.
Under this project, MHB is responsible for the construction engineering, fabrication, mechanical completion, load out and sea fastening, plus architectural works on an engineering, procurement and construction (EPC) basis.
The duration of the project is approximately 36 months, with fabrication to begin in 2025 and completed by 2028.
MHB secured the first subcontract for the IJmuiden Ver Alpha project in November 2023 from Petrofac.
In addition, MHB and Petrofac will collaborate towards the possibility of another OSS of similar size.
MD and CEO of MHB, Mohd Nazir Mohd Nor, said: “We are pleased to announce the successful award of our second offshore wind project, a subcontract to build an OSS HVDC platform, further fortifying our track record in clean energy, in supporting the global net zero ambition.
“Building upon our initial strides, this recent subcontract win is a crucial milestone for MHB.
“It signifies our contribution to TenneT’s significant 2GW Programme in the Netherlands, supporting the rapid development of large-scale offshore wind infrastructure projects which are crucial to Europe’s energy transition.
“We extend our heartfelt gratitude to our client, Petrofac, for entrusting us to be a part of this monumental project and for their confidence in our abilities.”
