Seatrium - Experts & Thought Leaders

ClassNK has issued an Approval in Principle (AiP) for an ammonia-fuelled ammonia bunkering vessel. This vessel is jointly developed by Nippon Yusen Kabushiki Kaisha (NYK Line) and LMG Marin AS (a member of the Seatrium Group). As ammonia fuel utilization is expected in shipping for decarbonization, bunkering vessels that supply fuel to ships and related equipment will play an essential role in the supply chain. Fuel engines from IHI Power Systems Additionally, a safety verification was conducted through HAZID involving relevant stakeholders This vessel is being developed jointly by NYK Line, advancing the development of ammonia-fueled vessels, and Seatrium, the largest shipyard in Singapore, with the goal of introducing it to Singapore, one of the world’s pioneering bunkering ports. This vessel is mainly designed by LMG Marin AS. It features ammonia fuel dual-fuel engines from IHI Power Systems and a bunkering boom from TB Global Technology, allowing for safe and reliable ammonia bunkering operations. Additionally, a safety verification was conducted through HAZID involving relevant stakeholders. New technology development and social implementation ClassNK carried out a review of the conceptual design of the ship based on its ‘Part N; Ships carrying liquefied gases in bulk ‘ of the Class Rules and ‘Part C-2; Guidelines for the Safety of Liquefied Gas Carriers Using Ammonia as Fuel (Edition 3.0.2) which is part of ‘Guidelines for Ship Using Alternative Fuels (Edition 3.0) and examined the result of required assessment. Upon confirming they comply with the prescribed requirements, ClassNK issued the AiP. Moreover, the latest ‘INTERIUM GUIDELINES FOR THE SAFETY OF SHIPS USING AMMONIA AS FUEL’ approved at MSC 109 last December are referred to in this AiP. ClassNK will continue to contribute to new technology development and social implementation, including safety assessments.

Penta-Ocean Construction, a prominent Japanese general contractor, has commissioned Ulstein Design & Solutions B.V. to design its new heavy lift vessel for offshore wind foundation installation. The customised ULSTEIN HX118 design will feature a 5,000-ton Huisman main crane and the ULSTEIN U-STERN™, which enables installation of increasingly larger monopile foundations. Ulstein's successful track Following feasibility and concept studies in 2023, Penta-Ocean Construction selected Ulstein for the project. Ulstein proposed the HX118 with the U-STERN™, a design that builds on Ulstein's successful track record of crane vessels. The selected design offers a well-balanced combination of a flush work deck, lifting capacity, accommodation and DP capability and will be the largest X-BOW® vessel to date. Basic Design of the heavy lift vessel The design is being set at Ulstein’s Rotterdam office, with significant support from Ulstein Poland The U-STERN™, developed by Ulstein, features longitudinal storage and upending of monopiles along the ship’s centreline. This innovation enables the installation of longer monopiles without overhanging the ship’s sides and allows the vessel to face into the waves during the installation, minimising ship motions and fuel consumption. Since last summer, Ulstein has been collaborating with Penta-Ocean Construction on the Basic Design of the heavy lift vessel, including an extensive model test program. The design is being developed at Ulstein’s Rotterdam office, with significant support from Ulstein Poland during the Basic Design phase. Monopile installation vessel "We are honoured that Penta-Ocean Construction chose us to design their new heavy lift vessel. This project represents a powerful collaboration between Penta-Ocean Construction, Ulstein and Huisman to design this most capable monopile installation vessel,” says Ko Stroo, lead designer at Ulstein Design & Solutions B.V. “As the project moves forward with its construction at the Seatrium shipyard, Singapore, we remain committed to supporting the parties throughout the construction phase.”

HullWiper’s sustainable hull cleaning solution is coming to Singapore. The company has signed a lease agreement with Unidive Subsea to bring its eco-friendly Remotely Operated Vehicle (ROV) hull cleaning technology to PSA terminals, Seatrium Yards and Singapore’s inner anchorages. Plans are also in place to expand services to FPSOs, FSOs and semi-submersibles under contracts with regional oil and gas companies. Net-zero emissions by 2050 HullWiper’s sustainable hull cleaning solution will support the Maritime Singapore Blueprint Singapore’s maritime industry is a key contributor to its economy, driven by its strategic location at the intersection of major maritime trade routes. Unidive Subsea provides diving and ROV services, supporting pioneering oil and drilling companies in Singapore. In partnership with HullWiper Ltd, they are focused on integrating cutting-edge technologies while promoting sustainable growth within the shipping industry. Set to launch in January 2025, HullWiper’s sustainable hull cleaning solution will support the country’s Maritime Singapore Decarbonisation Blueprint, which aims to achieve net-zero emissions by 2050 through responsible and safe maritime practices. Sustainable shipping practices "Innovation is key to success, and with Singapore's maritime sector being a lynchpin to our country's economic growth, having HullWiper in this region opens up new opportunities," says Jeremiah Chen, Unidive Subsea’s Director, adding "It allows us to refine traditional service methods and adapt to the ever-evolving demands of this dynamic industry." Singapore has long been a pioneer in advocating for sustainable alternatives, with the Maritime and Port Authority actively driving initiatives to promote sustainable shipping practices through policy, technological innovation and international collaboration. Cargo or bunker fuel operations The use of ROVs not only improves safety by reducing the risks associated with classic diver-based cleaning HullWiper aligns with this commitment by offering an eco-friendly hull cleaning solution that minimises downtime for vessels in the busy waterways of Singapore. The ROV technology enables cleaning operations to occur day or night, in most weather conditions, and while cargo or bunker fuel operations are underway. The use of ROVs not only improves safety by reducing the risks associated with traditional diver-based cleaning, but also ensures that residues and contaminants are collected and filtered through environmentally responsible processes, protecting marine life and water quality. Cleaner, greener shipping "HullWiper’s ROV technology offers an eco-conscious approach to hull cleaning," says John Armstrong, HullWiper Managing Director, adding "It makes hull cleaning more efficient, safe and environmentally friendly, allowing vessels to operate at peak performance while reducing fuel consumption and lowering GHG emissions." Since its launch in late 2013, HullWiper has expanded from its first base in Dubai to key locations across the Middle East, as well as ports in Australia, South Korea, Mauritius, Panama, Denmark, and Sweden. HullWiper has completed over 2,000 hull cleans for vessels worldwide.
