STEP® Marine Interior:

You can go anywhere in Holland, and never be far from a canal. These waterways are as beautiful as they are practical. Holland canals serve a number of very important purposes. They were used to drain the land so homes and farms could be established where once there was water. They provide a means of transport for goods from inland regions to the sea. They are homesteads for thousands who live on houseboats and they act as sewers. They are part of the Dutch landscape and a beautiful example of human ingenuity.

Houseboats are very popular and can be seen on most canals in Amsterdam. Electro Plastics was asked to offer a heating system for one of these houseboats. Drawings and specifications of the houseboat were given to Electro Plastics and, as total heating was requested, a heat loss calculation and layout were made.

Holland has a temperate climate, but winter can be quite cold. The land is surrounded by much water and rainfall averages 3 to 4 inches all year round, bringing in a lot of humidity.

The boat’s hull is made of concrete and the living quarters include wood and glass. The ground floor consists of the entry, a hobby room, a bathroom and a bedroom. On the second floor you have an open stairway to the entry and the living room with an open kitchen. The third floor has a loft used as a computer area open to the second floor and an outside terrace. The total heated floor space is 1,642 square feet.

The structure from the ground floor to the top ceiling is 14.75 feet high and the glass windows total 290 square feet. With so many windows and open spaces, it was important to choose a heating system that could satisfy this particular structural design and humid environment.

The heating system installed is STEP® Marine, a thin, flexible, low-voltage (24V) Nano Polycarbon element. The heating elements are self-regulating and cannot overheat. As the material gets warmer, less electricity passes through the plastic and so less heat is generated, it is therefore extremely energy efficient and can be used under almost any flooring – even under wood. Also the elements are light weight and can be cut to size on the jobsite, making it easy to install, especially for a retrofit application.

With STEP® Marine the owners are able to enjoy comfortable, healthy and even warmth in this creative houseboat.

Turquoise was established in 1997 by two leaders of the Turkish boat building industry, Proteksan Yachts Inc. and Turquoise Yacht Construction.

Turquoise Yachts is head quartered in Istanbul, the Gateway to the Eastern Mediterranean and has tow shipyards on the outskirts of the City, one in Pendix and the other in Koceli.

TURQUOISE NB72 – 56m (2019)

Turquoise NB72 is a 56m luxury yacht, built by Turquoise Yachts to be delivered in 2020. Her top speed is 17.0kn and her power comes from two diesel electric engines.

Currently under construction in Istanbul, Project Lombok  features an aluminium superstructure and an ice classed hull. This makes her suitable for exploring Polar Regions and navigating the Northwest Passage.

The interior décor is being developed by Hoek Naval Architects in collaboration with British design studio Vickers, featuring subtly classic touches and teak detailing throughout. Intimate cosy indoor spaces contrast with the expansive open decks, giving guests a wide range of relaxation options on board. In total, this 56 metre explorer yacht will have an internal volume of 785GT spread across four decks.

To offer comfort and warmth, all bathrooms have STEP Warmfloor heating elements under the tiles.

NB63 - 77m (2017)

Turkish yard Turquoise has delivered its largest yacht to date in the form of the 77 meter Go. Go was previously known as Project NB63, was launched in March and completed successful sea trials shortly afterwards.

Sold in January 2017, Go was designed inside and out by British studio H2 Yacht Design with a hull color that pays tribute to the yard’s name. The overall aesthetic has been described by Turquoise as “a modern evolution from the 2012 launch Vicky”.

Accommodation is for up to 18 guests split across nine cabins, while the crew quarters allow for a total staff of up to 20 people. Guests arriving in the main lobby will have the choice of using the elegant superyacht staircase or a full-sized elevator to access the main deck, where there they will find a saloon and a formal dining area.

Key features include a separate owner’s deck with a forward-facing suite and a private spa pool, a five meter swimming pool on the aft deck and a superyacht beach club that measures 162 meters square. A separate garage will allow storage for a ten meter limousine and an eight meter multi-purpose tender.

STEP Warmfloor heating elements were installed under the floors, for a total area of 124m2, to keep warm the owners, his and hers bathrooms, lobby, office, decks, salon, pantry and the main floor 7 guest bathrooms, salon, lobby, and bridge deck..

NB60 - 47m (2016)

This exciting revised 47m New Build has been updated with fresh clean sharper lines, the design is both modern and yet graceful and timeless.

New features include a beach club with access onto an extended swim platform, extra large hull windows that give tremendous feeling of light into the owners suite and a revised foredeck arrangement for all the tenders and toys. Care was taken to keep the view clear from the yacht so all fashion plates on both main and upper decks have been removed to provide an open linear appearance. The sun deck also takes on a new arrangement with the addition of a jacuzzi centrally located and plenty of seating and a bar.

The allure of the 47m is that it skillfully offers the owner a flexible and functional layout typically found on a larger yacht. Whilst the main deck boasts an elegant main saloon and dining area, there is also the option to relax and entertain in the full beam upper deck lounge, a generous multi-functional space for all the family.

The full height hull windows in the owner’s cabin and upper deck saloon offer extraordinary vistas, again more typically associated with a larger vessel.

The lower deck has been completely reconsidered providing two spacious VIP’s and two guest cabins.

The master bathroom and the 8 guest rooms have STEP Warmfloor heating elements to maintain the floor tiles warm.

Luxurious yachts with the ultimate comfort – heated floors.  Benetti installed STEP® Marine in the bathrooms to take away the chill of cold tiles.

STEP® Marine can be installed under most floor coverings – including ceramic and porcelain tile, natural stone, hardwood and laminates, resilient and carpet.

STEP® Marine is a patented, thin and flexible semi-conductive plastic mat which operated on low-voltage. It is self-regulating and cannot overheat. The nature of the Nano Polycarbon material automatically reduces or increases its heat out put to adjust to temperature changes; this means that when the ambient temperature gets warmer, the electrical resistance increases, and the consumption of electricity decreases. The system has low power consumption and is maintenance free.

STEP® Marine is cut to length on the job site making it ideal for both new construction and retrofit. The system is available – from floor warming to partial or total heating.

STEP® Marine Exterior:

James M. Keen – Olmsted L&D Lifter (2017)

The crane barge, Jams M. Keen, was built at Conrad Shipyard in Morgan City, Louisiana. The barge measures 110 feet, 6 inches by 60 feet with a molded depth of 8 feet 6 inches. In addition to barge construction, Conrad will also install two government-supplied cranes – a wicked lifter crane and a telescoping marine crane. The floating crane barge will be used to raise and lower the steel dam wickets and perform maintenance functions at the Olmsted Lock and Dam on the Ohio River.

For personal safety, STEP® Marine heating pads were installed under the whole deck surface to prevent snow and ice built up.

STEP Heating Elements in Gymnasium and Cafeteria

For more than 60 years, Gladding-Hearn Shipbuilding, Duclos Corporation, has built exceptional steel and aluminum commercial vessels. Located on the Taunton River in Somerset, Mass., the family-owned and operated shipyard counts more than 417 vessels built as proof of its longevity and vessel reliability.

The Gladding-Hearn brand is synonymous with pilot boats, with more launches operating in the United States than any other shipyard.

The shipyard’s long association with C. Raymond Hunt Associates led to the first deep-V pilot boat hull, which cut commuting times in half and permitted safe boarding at higher speeds. Now the industry standard, Gladding-Hearn’s all-aluminum pilot boats – ranging in length from 40-foot launches to 75-foot station vessels – are characterized by a soft, dry ride, steady tracking, maneuverability, rugged construction, low upkeep and reliability.

Pilot Boat - Alaska 423 - 75ft

This new 75′ aluminum waterjet pilot boat for Valdez, Alaska is based on the proven Texas class boats working in Galveston. Central to the concept is size. At 75 feet, they are big enough to cope with all sea states.

With Alaskan weather entirely different than the Gulf of Mexico, the new boat has multiple heating systems to keep the interior comfortable; the windows defrosted and the decks and handrails ice free.

The heat trace system used is STEP® Marine, because of its low-voltage safety features, ease of installation and no maintenance.

In Valdez, Alaska, where Crowley’s 10,192-h.p. tugboats will be utilized, the average annual snowfalls is 300 inches and in recent years temperatures have gone as low as -40oF. Even the common winter temperatures, which are more moderate, are accompanied by wind chills and cold spray that freezes on tug decks. Regardless of weather conditions, operations go on year-round, docking and undocking tankers and escorting the huge oil vessels out of the harbor and into Prince William Sound.

Vessel Management Services, Inc., the Crowley Maritime Corporation subsidiary, charged with designing and overseeing construction of the new tugs spent two years in research, ultimately choosing STEP® Marine, a low-voltage Nano Polycarbon heating system to prevent accumulation of ice and snow. The solution used until now by Crowley for heating decks involved a network of pipes through which the tug’s engine-coolant water is circulated around; however the piping requires continuous maintenance to control cracks and leaks. STEP® Marine would provide the same safety for personnel and deck equipment while reducing the maintenance costs associated with the previous warm-water solution. The construction was done at Dakota Creek Industries.


Police Department of New York – NYPD 1503 (2017)

Ice Class St. Lawrence Seaway Tug – Seaway Guardian

The U.S. Department of Transportation’s Saint Lawrence Seaway Development Corporation (SLSDC) reported the arrival of its new tugboat, the Seaway Guardian, in Massena, N.Y.

The vessel has been on a three-week journey through the Gulf of Mexico, around Florida, and up the Atlantic seaboard from Gulf Island Shipyards in Houma, La., where it was constructed. The Seaway Guardian will be the first new American-built tugboat to join SLSDC since Seaway opened 61 years ago.

“The St. Lawrence Seaway is important because it provides access for American raw materials, manufactured goods and agricultural products to be exported all over the world. The Seaway Guardian is the first new American-built, American-crewed tugboat to join the Saint Lawrence Seaway Corporation in 61 years.

Construction of the Seaway Guardian, which is a Robert Allan Ltd TundRA 3600 tug capable of operating in difficult ice conditions, began in 2018. The keel was laid on June 26, 2018 and the vessel launched on September 12, 2019.

The Seaway Guardian’s primary missions will be buoy maintenance and ice management. It will also assist in firefighting and emergency operational response on the St. Lawrence Seaway.

For personnel safety and to be able to navigate in all weather conditions, adequate STEP® Marine heat tracing systems were added to the decks, the hatch drains, the fire stations and pipes.
