SLPE-Designed Hollandse Kust (Noord) OSS Substructure Enters Final Stages of Fabrication

SLPE had the recent privilege of seeing TenneT’s Hollandse Kust (Noord) OSS substructure enter the final stages of fabrication, with the roll up completed and the 2-part cable deck now successfully installed.

SLPE was responsible for the design of the substation’s jacket foundation.

“It is always a proud and exciting moment seeing our hard work coming to fruition on the fabrication yards of Smulders and Heerema”, said Sam Lawes, Head of OSS Substructures at SLPE. “Our team has worked efficiently and decisively throughout the entire project, keeping to tight schedules and doing all we can to surpass our client’s expectations”.

As part of the project, SLPE has designed frames to house ‘biohut’ cages, which will be attached to the jacket and filled with oyster shells. These cages replicate the ecological function of a shallow water nursery to help support a sustainable biodiversity of the marine offshore environment.

“It is both encouraging and rewarding being part of a project that has taken a proactive approach towards sustainability”, Sam added. “Our oceans are a vital resource that we must all work hard to protect. This project is a great example of one of the many ways the offshore industry can play a significant role in preserving and restoring the health of our oceans”.

The Hollandse Kust (Noord) substation will be installed approximately 18.5 kilometers off the Dutch coast and is expected to be fully operational in 2023.

At SLPE, we apply safe-by-design principles considering the entire project lifecycle. Our offshore foundation designs are also optimized for fabrication and marine operations, drawing from our extensive experience of collaborating with the industry supply chain.
