Alternative fuels, Hydrogen
14th April 2022

Hydrogen has gained much spotlight as alternative energy fuel in recent years. The marine industry is also now seriously considering Hydrogen as a viable option. There are several ongoing studies to study the viability of Hydrogen as a possible fuel. This post will look at Hydrogen and give you some key facts. 

Hydrogen is a colorless, odorless, and non-toxic gas. There are three ways in which ships can use hydrogen for marine applications:
  1. Cryogenic Liquid: The volumetric density of liquefied H2 (LH2) (71 kg/m3) is only 7% that of HFO. This results in approximately five times the volume compared to the same energy stored in the form of HFO, resulting in more volume and transport cost.
  2. Compressed gas under high pressure: When stored as a compressed gas, its volume is roughly ten to 15 times (depending on the pressure [700 to 300 bar]) the volume of the same amount of energy when stored as HFO.
  3. Hydrogen can also be stored within solids (a phenomenon called absorption) or on the surfaces of solids (adsorption). Both of these methods are not so commonly utilized in marine applications. 

Hydrogen is the lightest of all elements, around 14 times lighter than air. Due to its density, it leaks very quickly and thus requires special attention in handling and logistics.

Despite its difficulties in handling, Hydrogen is a widely used chemical commodity. It can be currently produced in two ways:
  1. Using Natural Gas: note that CO2 is a byproduct of this extraction process. If carbon capture is part of the process, it can significantly reduce carbon emissions. 
  2. Using electrolysis: this relates the cost to the generation of electricity. Electrolysis is particularly interesting because it does not require any existing infrastructure except electricity generation. In particular, if the electricity is produced through nuclear and renewable energy, then carbon emissions can be extremely low if not net zero.

But what technologies can be utilized to generate energy from Hydrogen without carbon emissions and any compromise on efficiency?

Fuel cells seem to be the most popular method, mainly because it doesn’t produce any carbon and could even eliminate NOx, SOx, and particulate matter (PM) emissions from ships. Other technologies are also being considered, including gas turbines and internal combustion engines. The important thing to note is that the lifetime of fuel cells is shorter than that of piston engines or turbines and depends on fuel quality and system operation management. In addition, while carbon emissions are still lower when compared with traditional fuels such as HFO, NOx is unavoidable when using internal combustion engines.

Conventional energy converters for Hydrogen like Internal Combustion Engines will have similar capital expenditures as LNG fuelled engines. But the real kicker comes when considering the cost of storage of Liquid Hydrogen due to its lower storage temperature and higher insulation quality. 
The price for H2 in the current market varies significantly because Hydrogen is still a part of the industrial gases market where individual contracts apply. Although one promising aspect to look forward to is when renewable energy production ramps up, then it can be used to produce Hydrogen, reducing the costs significantly

Hydrogen as an alternative fuel is still a promising option despite its complexity in handling and lack of significant infrastructure.

Rotterdam office opening ceremony performed by Andres Sutt, the Minister of Entrepreneurship and Information Technology of Estonia
6th April 2022

On the 4th of April, the Estonian Ambassador to The Netherlands, His Excellency Ambassador Lauri Kuusing, and SRC Netherlands BV hosted a grand opening event for SRC's expansion to the Port of Rotterdam. The opening ceremony was performed by Andres Sutt, the Minister of Entrepreneurship, and Information Technology of Estonia.

The new office is located at the corner of the entrance to Waalhaven. SRC will have direct access to a large quayside which is located adjacent to the new office facility with a berthing capacity of 45 m width and 10.5 m draught. Lifting services along the quayside are provided by four cranes with a lifting capacity of up to 100 tons. Additionally, storage facilities and covered fabrication areas are provided. Complementary logistic services can be provided by SRC’s onsite partner Broekman Logistics.

The relocation to Europe's No. 1 shipping hub is a big step in the value proposition for our customers, with almost no limitations on the characteristics of ships that SRC can accommodate. With that move, SRC is stepping into the bigger maritime business playground and continues to secure future growth. 

Specialized in EPCI solutions to any vessel type in any location in the world and well-placed with knowledge and capability to lead and execute complex, multidisciplinary projects with tight schedules which require tailored solutions. From engineering to final installation – SRC has completed more than 5000 projects across the world and managed up to 1000 people per project. Offices in Estonia, Italy, Norway, Poland, the US, and the Netherlands.

In 2017, SRC Netherlands BV, part of the SRC Group AS was established in Dordrecht from where the company mainly focused on sales and business development activities.

Holistic design and installation solutions for ballast water treatment systems
25th January 2022

Around the world there are numerous examples of devastated marine wildlife caused by invasive marine species. Ballast water is one of the most important reasons why invasive marine species get the chance to get introduced to new marine environments as vessels carry them around the world in their ballast water tanks.

In 2004 the International Maritime Organization (IMO) therefore introduced the Ballast Water Code (BWC) to address the Control and Management of Ships’ Ballast Water and Sediments. Today there are many options available on the market for ballast water treatment systems (BWTS) however, integrating such a system onboard of a vessel in operation, isn’t always as straightforward as it seems and often requires modifications.
The Baltic Sea is a special area for the discharge of sewage into the sea in accordance with MARPOL Annex IV.  In association with this, stricter discharge limits for sewage already apply since 1 June 2019 for newly built passenger ships while for existing passenger ships they have entered into force from 1 June 2021.
Under certain conditions, an extended transitional period ending on 1 June 2023 for single voyages of passenger ships into Russian territorial waters east of the 28°10´ longitude and back.
The stricter discharge limits for the special area can be achieved with the installation of advanced wastewater treatment plants (AWWTP). The discharge limits for these plants (phosphorus: max 1.0 mg/l or 80 percent reduction, nitrogen: max 20 mg/l or 70 percent reduction) are similar to those for land-based municipal treatment plants and significantly reduce the nutrient input into the Baltic Sea.
With an extensive track record, the SRC Group has become an expert with regard to the integration of such BWTS systems. We offer our customers design and installation services for BWTS to ensure that their vessels comply with international rules and regulations regarding ballast water management, including the aforementioned stricter discharge limits. SRC has worked on all types of vessels and we have experience with a large variety of BWT systems. Our services include the complete design of piping & electrical systems, workshop documentation, and installation & commissioning. As with every technically challenging project, our in-house 3D scanning service and pre-fabrication philosophy will be brought to the benefit of your project to allow for a smooth integration process onboard without surprises.
