Battery-Powered SOVs, CTVs To Soon Become Cheaper than Their MGO Alternatives, Study Says
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Studies commissioned by ScottishPower Renewables found that battery-powered vessels (re)charging offshore is feasible and could be part of the operations of future offshore wind farms. One of the reports also says electric operations and maintenance (O&M) vessels will become cheaper than their Marine Gas Oil (MGO) alternatives within the next few years.
The article is definitely a must-read, as it talks in detail about using service operation vessels (SOVs) and crew transfer vessels (CTVs), that are powered by electricity, rather than by marine gas oil (MGO).
Rolls-Royce Powers World’s Fastest Offshore Crew Transfer Vessels
The title of this post, is the same as that of this news item from Rolls-Royce.
These three bullet points, act as sub-headings.
- Sea trials demonstrate maximum speed exceeding 53 knots under operational load.
- Each of the three ships is powered by four 16-cylinder mtu Series 2000 engines.
- 35-meter ships are designed as “Surface Effect Ships” (SES)
This is the introductory paragraph.
The Singapore shipbuilder Strategic Marine has commissioned three new offshore supply vessels that, with a maximum speed of over 53 knots, are the fastest of their kind in the world. Each vessel is powered by four 16-cylinder mtu Series 2000M72 engines from Rolls-Royce. The vessels will be used by a national oil company in Africa for passenger transfer to offshore platforms. To enable fast and safe transfer, the 35-meter-long vessels were designed as so-called “Surface Effect Ships”.
This Rolls-Royce image shows one of the Crew Transfer Vessels at 50 knots.
On a slightly different tack, this Rolls-Royce image shows The Spirit of Innovation.
Rolls-Royce described it in this press release which is entitled ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, using these words.
During its record-breaking runs, the aircraft clocked up a maximum speed of 623 km/h (387.4 mph) which we believe makes the ‘Spirit of Innovation’ the world’s fastest all-electric vehicle.
I’ve probably been over 1,300 mph in Concorde.
So are the three offshore supply vessels, the fastest of their kind in the world?
This video shows one of the Crew Transfer Vessels doing, what they are intended to do.
Rolls-Royce seem to be borrowing a philosophy from their past, where they showed in the Schneider Trophy, just what their engines could do.
These two paragraphs describe the design of the Crew Transfer Vessels.
To enable fast and safe passenger transfer to offshore platforms, the 35-meter-long vessels have been designed as so-called “Surface Effect Ships” (SES). SES uses air-cushion technology within a catamaran hull form. This design was used for the first time in the offshore oil and gas industry.
The boats have an optimized power-to-weight ratio and use powerful fans to generate an air cushion between the hulls that minimizes hull drag and resistance. Combined with the mtu propulsion package (each delivering 5,760 kW of power), the vessels can travel at much higher speeds than conventional monohulls and catamarans, with consumption remaining at the same per hour of operations. The high speed of well over 50 knots (more than 90 km/h) ensures shorter transit times, while the low hull resistance saves fuel and reduces emissions.
I believe, that the Rolls-Royce mtu diesel engines used in these vessels can also be fueled by hydrogen, so is that the next development?
Could we be seeing hydrogen-powered fast ferries on short sea routes around the world?
