The Dutch Government will soon be inviting offshore wind power companies to bid on building two wind farms off the Dutch coast.
Companies bidding the lowest price will be awarded a 30-year permit to build and operate the relevant wind farm.
So it’s not a surprise to tell you that everyone will be extremely focused on cost control measures.
From our experience, it will be important for those involved to understand how proven subsea cable equipment can reduce the overall cost over time. And throwing the cheapest solution out to grab a bid could be a very costly problem in the future.
While our high-end, custom engineered subsea cable hardware may not be the cheapest on the market, our engineering team understands there are other ways to save costs. Our experience led us to create “No Tools Required” custom cable systems, and our in-depth hydrodynamic efficiency studies are helping other companies innovate new systems on existing subsea cable devices and analyze cost saving opportunities.
According to the Government, critical to the overall plan for The Netherlands is that the energy produced from renewable sources is cost-competitive. In meeting its future energy demand, the country aims to keep costs under control.
For most wind projects, the pre-construction and even pre-bid costs are high for individual companies. Costs must be made for site investigations, for environmental impact assessments, and so on. This increases risks for bidders, and by consequence the overall costs for offshore wind development. To address this, the Dutch government has now decided to take over the responsibility for many of these pre-development issues. Read more…
Offshore wind might be a new industry, but they are as just as focused on cost efficiencies and simplified solutions as our clients in oil and gas. Those who support them need to supply and produce reliable products that increase performance and lower costs.
Our past customers pushed us to innovate and develop “No Tools Required” custom cable systems, and our in-depth hydrodynamic efficiency studies are helping other companies innovate new systems on existing subsea cable devices and analyze cost saving opportunities.
And we are not alone in our efforts. German industrial group Siemens unveiled a new direct-current solution for connecting offshore wind turbines to the grid which can lower costs by as much as 30%. Read more.
When laying and retrieving submarine cables on the seabed, or performing a cable pull from a vessel to an offshore wind platform, it is often necessary to hold a cable end onboard for up to seven days.
Cables must be anchored firmly onboard to keep them in place, and this anchoring is normally done by means of a cable stopper.
The cable left hanging in the ocean can be exposed to forces so strong there is a distinct possibility of becoming overtensioned. Meanwhile, the vessel’s crew works to keep station by the use of thrusters. If overwhelmed by winds, strong currents and waves, the ship can be driven out of position. The cable left hanging may end up acting as an anchor chain, subject to additional forces and tension.
In these situations, when the wrong cable hardware is used, or is installed incorrectly, the grip of cable tensioners can slip. The heavy cable starts moving unfastened, which is extremely dangerous for the crew, equipment and the vessel.
While the oil, gas and seismic industries have had plenty of experience with these issues, the growing offshore renewable energy companies are looking to manufacturers like PMI Industries for proven experience and products to guide the way.
Engineers who have made the leap from offshore oil to offshore renewable energy have worked with PMI’s products, such as our CABLE-GRIP™ and STOPPER-GRIP™ Terminations, and have found them preferable to typical braided cable grips or cable socks. These terminations are quick and easy to install, robust, and recommended by many cable deck crews.
Our unique cable grips are fully capable of holding cables to the rated breaking strength. Tensile load is transferred gradually from cable to termination with no stress or damage to the cable. And unlike braided stoppers, the helical termination wire design permits installation anywhere along the length of the subsea cable, since it does not require access to the cable end.
7 Questions You Should Be Asking About Your Subsea Terminations
Operators and suppliers in the offshore oil and gas industry face major challenges as the industry matures: increased production losses, technical issues with legacy equipment, evolving business models for maintenance and repair, supply chain constraints, rising delivery costs, and an inability to improve production.
Companies are even putting off recruiting apprentices because of the time and cost involved in what is perceived as a complex process. That why it’s good news to hear that Subsea UK has launched a new support service to help companies bring new talent into the subsea sector by making it easier to recruit apprentices. That’s one solution to the many the industry face.
And while Subsea UK is helping on the employment front, we’re focused on the other issues – constantly working on new to improve cost efficiencies. One way we are doing this is by innovating news systems on existing subsea cable devices and analyze cost saving opportunities.
Our in-depth hydrodynamic efficiency studies are helping companies by optimizing performance and overcoming hydrodynamic drag by over 40%.
