Over 90 percent of world trade is carried across the world’s oceans by some 90,000 marine vessels and the marine sector would be unable to meet the CO2 emission standards for 2030 and 2050. Currently, maritime shipping total to less than 3% of global greenhouse gas emission but is projected to increase to 17% by 2050 due to the slow advancement of marine technology.

With the growing demands for clean energy, the path towards FER systems is inevitable. Sea Forrest advocates for a change in this industry through a plug-in hybrid retrofit and new buildings for the vessel. The FER and Parallel Hybrid sees to potentially reduce carbon emission by up to 20%.

For current traditional vessels, engines are not turned off when vessels are loitering. However, for the Parallel Hybrid Design, propulsion of the vessel can be by engine and/or electric motor through two modes: Eco and Power Mode.

Eco Mode sets the vessel to only use electrical propulsion at slower speeds, only using a single engine to kick in and run the propulsion when there is a speed increase. The engine will only remain on if the speed increases further. Power Mode is like the Eco Mode however it allows for the motors to boost the speed of the vessel for a short time.

This Parallel Hybrid system allows for the same operation function of a normal diesel engine propulsion system. With slower speeds, the vessel will operate like an electric vessel. While at higher speeds, the propulsion system operates like a normal diesel vessel. This makes the system suitable for vessels that use a full range of speed and have long loitering times.

Combined with the Energy Cube, the Parallel Hybrid system has its electric motor coupled to the engine to charge the Energy Cube, the energy stored could be used as hotel load, electric propulsion and as a booster when the ship needs an increase of speed. This energy cube is also compatible with an FER system as well.

This hybrid retrofit serves as a transitional process to the futures of the FER system by offering step-changes to our key contributors, making hybridisation more convenient and economical for owners.

Installation of Singapore’s first hybrid propulsion system on Penguin Tenaga has allowed for Sea Forrest to gain valuable experience allowing us to continue improving and meeting the unique requirements of every customer.

As electric vessels start to gain popularity among the masses, there needs to be a way to store the electrical energy.

Sea Forrest has engineered and designed the Green Cabin, a one stop solution to storing excess energy generated by the engine to be utilised as hotel load or on non-essential applications. This system reduces potential environmental impact and shows improvements for indoor environmental quality for better health and wellbeing.

The Green Cabin also has a scalable modular design to fit any customer’s preference, making it a portable and durable solution for any electric vessel. It is also highly customizable allowing Sea Forrest to make continual improvement on it. Installation will help with reducing emission during idling/loitering operations when the ship engine is turned off.

Traditional batteries are an area of concern due to their limited shelf and use life, causing wastage of natural resources for continual production of new batteries which in turn produces substantial environmental harm as well. The Green Cabin can eliminate the potential for extra energy and material waste.

Sea Forrest has also been working towards the development of Energy Cube, an Energy Storage System, that can be integrated onboard or on land into the vessel’s power system seamlessly. This Offshore Energy Cube with Tesseract Charging System converts gas associated to oil extraction (flaring) into electrical energy for electrified vessels.

There are a few methods to charge up your electrical vessel for a trip. Sea Forrest has developed a range of charging capabilities for both land, offshore and Ship-to-Ship charging.

The Smart Electric Charging system is a necessary component to complete the electrification ecosystem by providing dockside high current charging to vessels via a conventional means of plug-in. The plug-ins are made of robust and durable connectors that click on with a constant tension to facilitate high-power transfer to ensure fast charging.

Although an onboard charger may be more convenient, the limitations in size, weight, and cost of equipment diminishes its usability.

The sleek design of the Sea Forrest Smart Electric Charging System consists of advanced safety features which counters the usual risks with off board charging, which include damage and wear and tear due to harsh weather conditions and the need for constant maintenance and repair.

According to the Global Autonomous Ships Market Report 2021, the market is expected to grow to $6.46 billion in 2021. Despite the large market, it has been recorded that human error is the cause of 75% to 96% of marine accidents. Being susceptible to human error on a vessel poses a huge concern for safety and profit.

Relying on both autonomy and remote pilotage can help reduce the chance for such human error, while also decreasing the reliance on foreign manpower and improve safety through autonomous function. Autonomous and remote pilotage vessels can increase the safety of aquatic life and increase fuel efficiency by using Real Time Assist AI Pilotage (RAP) to calculate the best path to every destination. This ideal route has a lighter carbon footprint compared to traditional means of travel.

The RAP utilises deep machine learning with a powerful algorithm on multi-layered APIs for navigation. A Realtime assistant would further enhance the standard anti-collision warning system with advanced optical sensors for both day and night navigation. Realtime data is constantly fed into the system, this in turn would optimise navigational behaviour and improve energy efficiency and emission.

Cheaper cost of expenses for maintenance and fuel have also caused the rise for such piloting methods. Autonomous ships use the same technology as other autonomous vehicles and rely on sensors along with the help of infrared and visual spectrum cameras supplemented by radar, sonar, lidar, GPS and AIS which will be able to supply data for navigational use. Whereas remote piloting allows qualified pilots, situated on land or on a pilot boat, to guide the vessel remotely.

With the emergence of Green Energy farming, companies are increasingly having to harness renewable energy in the form of Wind, Solar and Tidal farms. Electrons are transported in a conduit of cables into the Grid or into Energy Storage System (ESS).

Sea Forrest has been supporting the Renewable Energy market by providing engineering expertise through Manufacturing, Installation & Commissioning of Cable Lay Equipment. Our capabilities ensure quality and reliable systems that will meet the robust standards demanded by both land and offshore operating environments.

Likewise for structural platforms, Sea Forrest provides the Development, Construction & Integration of the structural platforms for ESS onto vessels and offshore platform. Sea Forrest incorporates containerizing solution for energy storage system with cooling system as a complete ESS solution.
