TecnoVeritas involvement was all about the update of S.S. DELPHINE energy optimisation and environment friendliness according to MARPOL annex VI. The vessel, propulsion plant is intact with the two original quadruple expansion steam engines, driving directly their respective propellers. With this project, TecnoVeritas is proving that a ship may not be scrapped due to its age, provided the hull is in good condition, and that vessels as S.S DELPHINE have their special owners and clientele, both sharing the joy and feelings of a unique vessel.

S.S. DELPHINE general arrangement.
"S.S. Delphine” is not a caprice yacht for owners who only want to know where their boat is during Easter vacation. This steel-hull vessel, requires a minimum onboard maintenance crew of 5 people whenever she sits idle. Her owner and guests must share the passion to maintain an oceangoing museum fitted with every luxury, navigational and security convenience imaginable.
"Horace Dodge spent $US2 million to build S.S.Delphine," that according to Mr. Bruynooghe says that's more than $US180 million in 2010 dollars, but the she cannot be replicated. Dodge designed and built the steam engines himself and they're very environmentally friendly."
Delphine's pair of 6-foot-tall propellers is powered by 20,000 liters of water converted in steam pressure by diesel fuel. "It's 19th-century hydrophysic technology that cuts costs and leaves a low pollution signature," Delphine fuel consumption cut down as well as the improvement of her environment friendliness were the main objectives of TecnoVeritas project.
The main boilers
SS Delphine is a yacht commissioned by Horace Dodge, co-founder of Dodge Brothers. The yacht was launched on 2 April 1921, and spans 258 feet (79 m). Power was originally supplied from three Babcock & Wilcox boilers powering two 1,500 horsepower (1,100 kW) quadruple expansion engines. In her 2003 refit Delphine was re-equipped with two modern water-tube boilers operating at 20 bars (290 psi), the larger of which has an evaporation capacity of 14 metric tons (31,000 lb) of steam per hour while the smaller can evaporate 4 metric tons (8,800 lb) per hour; these new boilers supply the original quadruple-expansion engines. "Of all the large American-built steam yachts built between 1893 and 1930, the S.S. DELPHINE is the only one left in her original condition with her original steam engines still in service."
The Delphine caught fire and sank in New York in 1926, to be recovered and restored. She suffered further damage in 1940 when she ran aground in the Great Lakes, and was repaired. She was acquired by the United States Navy in January 1942 and rechristened USS Dauntless (PG-61), to serve as the flagship for Admiral Ernest King, Commander in Chief of the U.S. Fleet and Chief of Naval Operations. She was sold back to Anna Dodge (Horace Dodge's wife) after the conclusion of World War II and restored to civilian standards and service, including her original name.

Delphine changed hands in 1967 and again in 1968, changing names again to Dauntless, only to be sold again in 1986, 1989, and in 1997 - at scrap metal prices to her next owners - who proceeded to restore her for $60 million to the original 1921 condition including interior decor and the original steam engines. She was rechristened S.S.DELPHINE by Princess Stéphanie of Monaco on 10 September 2003. She was recently acquired by its current owners in 2015 and will return to its home port of Monaco for the 2017 charter season.
The NOVEL application of ultrasonic waves is used in the fuel oil “reformer” which improves combustibility by dispersing any sludge remaining after treatment by the centrifugues. Treatment of fuel oil before combustion in a diesel engine mainly aims at eliminating foreign matter suspended in the fuel oil.
Application of an efficient treatment system after the centrifugues will improve combustability by homogenising particles and sand , metal and catalytic fines.
Some major power plants companies in Europe and India, operating marine diesels as generators prime movers have reported the burn of 100 per cent heavy fuel in their engines.
Central to the operations an ultrasonic horn and a cylindrical rotary filter mesh coated with a 5 microm mesh filter, through which the fuel flows from the outside into the inside.
Suspended solids are retained on the outer filters surface. These are conveyed by rotation to the dispersal area below the horn where and intensive ultrasonic wave of 20 kHz irradiates the liquid, cracking the long chain asphastenes molecules and any debris. The cavitation produced by the ultrasounds guided waves produce instantaneously high temperatures and pressures, being the mechanism behind the solution.
Special features claimed are:
The rotary collector and horn are designed to be free of erosion by ultrasonic attack. Maintenance is kepy to a minimum as ultrasonic transducer and radiator cacatrode are made of titanium, having a proven long life and other system components are of non wearing nature. Operation is simple, not requiring any special training. The unit may be started remotelly, and is fully automated, being possible the display of many operational variables like, flow rate.
The models that are available, are capable of covering most of the shipping industry requirements , ranging from 6 ton per day, up to 6 ton a hour.
The unit can be, operated in-line, or in a batch arrangement.

“We are scouts, we are used to live adventures that stimulate us and test our limits. But this time it was different: Two students, a Renault 4L, more than 120kg of school supplies to donate, a roadbook and a compass.
Everyone called us “crazy of our mind” when we said that we would go to Morocco, to do a solidarity raid. We took care hard of this ambition, recruiting supports and the dream started to get alive because of our determination and work.
We went from Lisbon to Marrakech and we came back, safe and sound, without the torture of mechanic issues, with an empty trunk from all the school supplies we gave, but a backpack full of smiles and hugs, as well as the sense of mission accomplished… for now.
It was ten days driving by unusual trails and retaining in the memory the best we lived on that land, with those people. It’s still hard to talk about this adventure, for so many contradictory emotions we lived and personal achievements we reached. But today we still feel it sounds too good to be true.
Step by step we learned new things every day, but above all to pay attention to all the mechanical details that the desert confronted us with and to retain a look focused on the reality that was lived there.
We completed 3553 km where we saw luxury, organized lands, beautiful landscapes, snow, sea, a desert to lose sight of, smiles, lots of smiles, but we were also confronted with sadness, poverty, affective and social lack, a mix of emotions with which we had to know how to handle to complete our journey and our purpose in a constructive way.
In one of the days, on the end of a stage, when we arrived to the camp, an institution of children and young people were waiting for us, and the major part of the school supplies were distributed. The satisfaction of those children touched us deeply, as we believed would touch anyone who would put themselves to the test and risk of making this trip for the benefit of others.
From the moment that we knew that if it wasn't the donation of UniRaid, the school year for those children and young ones wouldn't be assured, we say for sure that the mission is not fulfilled because the desire of coming back remain in us. There is still a lot to do in the world, a lot to give to others and a lot to learn to be a better person. See you in the next year!”
On board desulphurisation system.
A disruptive solution for low sulphur fuels availability!
The desulphurization system, is another addition to the portfolio of technologic possibilities available to shipowners and ship operators to deal with envisaged lack of low sulphur fuels around the world. This solution, allows the use of high viscosity and high density fuels as before, treating these fuels onboard, and disposing the removed sulphur compounds (sulphones and sulphoxides) ashore.
TecnoVeritas has been involved for more than 20 years with ship energy efficiency. Pursuing the research and development of technology based on water in fuel emulsions assisted by ultrasounds, resulted in a spin off technology that may be playing a decisive solution for the use of low sulphur fuels on board existing vessels.
The patented Ultrasound Assisted Desulphurisation technology by TecnoVeritas, when installed onboard, allow the ship to bunker virtually any quality of fuel to be bunkered, including the fuel with 3.5% sulphur, the only available in many ports of the world.
The system, based on ultrasounds make use of onboard produced reactants as well to promote the sulphur oxidation at low temperatures, as sulphones and sulphoxides that can be disposed with other slop oils. Other reactants used are cheap, and regenerated during the process, by using waste heat on board.
The system has been in operation at laboratory scale for about one year, undergoing analytic tests and optimisation, although at industrial scale, a slop oil treatment plant ashore, in Setúbal, Portugal, is equipped with one such desulphurization unit with a throughput of 6 tons per hour.
Hyunday Heavy Industries, have demonstrated a great interest on this desulphurisation technology, being under negotiation a MOU, to offer the technology for new constructions.
The system, is to be delivered in skid, and is available with capacities up to 6 ton per hour.
TecnoVeritas engineering consultancy services, was called on board the bunker vessel S. Jorge on the past 10th of March to perform the verification of alignment between one main engine and Schotel type propulsors.
The verification was sucessfully done by using a special tolls for laser alignment. This job, was particularly demanding as the main engine is driving the propulsors via a cardan shaft, which call for a particular procedure, since in this type of transmission, the main engine drive flange must stay absolutely parallel to the propulsor power intake flange. The figure, shows the special tools used to perform the laser alignment.
The vessel overhauling is taking place in Lisbon Naval Rocha Shipyards, where she is dry-docked since October 2016. The revamping is aiming apart of other maintenance tasks a fuel consumption reduction in excess of 20% making her one of the most Eco friendly Luxury Yacht on business at date.

S.S.Delphine is receiving new boilers controls for optimised air fuel ratio, feed water economisers, but also the NATO approved Voyage Energy Efficiency Optimiser VEEO (1st prize of Sea Trade Awards Clean Shipping 2012) and BOEM-S (Blue Overall Energy Monitoring system).
By using these two solutions from TecnoVeritas, ship management is capable of optimising the Delphine’s operations, being connected digitally to the vessel.
VEEO is connected to Optipower that is measuring the two shaft lines Torque, Thrust and RPM, therefore allowing the monitoring of hull and machinery condition. VEEO is delivering crucial information to the crew regarding the level of energy use at any moment while advising the way to improve it. Weather routing and voyage optimisation was also deployed.
BOEM-S toolbox include Ship Performance and its prediction, Energy Management and its accountancy, Maintenance Management, Ship Document Management, and Condition Monitoring of the most crucial ship systems components like condensers, which have a strong impact on fuel consumption. A most important detail, is that, reporting is fully automated without human intervention, therefore freeing ship crew for other tasks, while ensuring a great reliability of data.
S.S. Delphine is also receiving from TecnoVeritas a special attention regarding sound and vibration insulation. Particularly optimised sound canopies and vibration mountings have been designed so that she will be offering their guests an unbeatable sailing silence.
SS Delphine is a yacht commissioned by Horace Dodge, co-founder of Dodge Brothers the American car manufacturer. The yacht was launched on 2nd of April 1921, with a length between perpendiculars of 79 m.
Power was originally supplied by three Babcock & Wilcox boilers powering two 1,100 kW quadruple expansion engines. In her 2003 refit Delphine was re-equipped with two modern water-tube boilers operating at 17.5 bars, the main boiler has an evaporation capacity of 14 tons/hour of steam while the auxiliary boiler can evaporate 4 ton/hour; these new boilers supply steam to the two original quadruple-expansion engines. Delphine is the only yacht built between 1893 and 1930 left in her original condition with her original steam propulsion plant still in service.
S.S.Delphine was also a warship. Delphine was acquired by the United States Navy in January 1942 and rechristened USS Dauntless (PG-61), to serve as the flagship for Admiral Ernest King, Commander in Chief of the U.S. Fleet and Chief of Naval Operations. She was sold back to Horace Dodge's wife after the World War II and restored as a civilian vessel and service, including her original name.
Delphine had different owners in 1967 and again in 1968, changing names again to Dauntless her name during the World War II, being sold again in 1986, 1989, and in 1997 – for scrapping. Her next owners have engaged her in an ambitious restoring project of $60 million bringing her to the original 1921 glamour including interior decor but keeping the original steam propulsion engines. She was rechristened again with Delphine by Princess Stéphanie of Monaco on 10th of September 2003. She was recently acquired by its current owners in 2015 and will return to its home port of Monaco around March 2017 for the charter season.
As a conclusion of this project, one can say that S.S.Delphine did not received a “face lift” as she is naturally beautiful, but, by the contrary she received a rejuvenation elixir that made her again not only even more beautiful but also Eco Friendly comparing to new builds of today.
