Basic Design & Earthquake analyses for HVDC Substation Jackets

Project Name: Basic Design & Earthquake analyses for HVDC Substation Jackets
Client: Undisclosed
Location: East Coast, USA

Project overview

Enersea completed the basic design for two jackets supporting offshore HVDC substations for a wind farm on the U.S. East Coast. The jackets, weighing approximately 7,500 and 9,000 tonnes, are designed to support substations with weights of 10,000 and 15,000 tonnes, respectively. These robust structures are critical for the stability and longevity of the HVDC substations, which play a key role in transmitting wind-generated electricity to shore.

Enersea was responsible for

Basic Jacket Design

Developing the structural design for two heavy-duty jackets to ensure reliable support for the substations in challenging offshore conditions.

Earthquake Analysis

Conducting comprehensive seismic analysis to account for potential earthquake impacts, enhancing the stability and resilience of the structures.

Temporary Phase Analysis

Performing analyses to address structural integrity and safety during installation and other temporary phases.

Project Significance

Enersea’s expertise in seismic analysis was crucial in designing jackets capable of withstanding potential earthquake forces. Earthquake analysis for offshore structures is complex, requiring precise calculations and modeling to account for dynamic loads and environmental conditions. This rigorous approach contributes to the overall resilience and reliability of the HVDC substations, safeguarding the long-term functionality of the wind farm’s energy transmission system.

Stage 2+ Project – A15 & B10 Development for Petrogas

Due to its expertise in developing small and economically challenging gas fields, Enersea was awarded the Front-End Engineering Design (FEED) directly by Petrogas and the Detailed Design contract through a close cooperation with HSM.

Riser and Pipeline Design Electrified Gas Production Platform N05-A

The N05-A project will be a groundbreaking offshore gas production platform, to be situated in the Dutch sector of the North Sea and developed by ONE-Dyas.
