Kongsberg Maritime has signed a major contract with Sea1 Offshore to deliver Launch and Recovery Systems (LARS) for the company’s four new offshore construction vessels. Each vessel will be equipped with two advanced LARS units, supporting subsea construction and ROV operations.The scope of supply per vessel includes two telescopic A-frames, fully electrical umbilical winches, energy efficient hydraulic power units, and a dedicated control system. Each system offers a safe working load of 15 tonnes (vehicle dry weight) and winch cable capacity of 4…

A new generation of hybrid vessels is demonstrating significant gains in both fuel economy and operational output. For Olympic Subsea’s owner and CEO Stig Remøy, it proves that technology-led efficiency is the fastest path to decarbonization—and a powerful business case.When Stig Remøy began pivoting Olympic Subsea toward subsea and renewables a decade ago, the move was met with some internal skepticism. “Naturally, there were internal discussions — some believed oil and gas was the future,” he recalled.

There’s an obvious fuel saving advantage, but partnering energy storage systems with new fuels brings other advantages too.There’s a new generation of vessels emerging which is exemplified by Grimaldi’s PCTC Grande Shanghai, claimed to reduce fuel consumption by 50% compared to previous-generation car carriers, and the NCL Vestland, a container feeder vessel similarly claimed to reduce energy consumption per TEU per nautical mile by 63%.What these vessels have in common is a propulsion system that combines energy storage systems and new fuels.As Henrik Helgesen…

New insights from DNV’s Maritime Forecast to 2050 indicate that the number of alternative-fuel-capable vessels in operation is set to almost double by 2028.By 2030, the alternative-fuelled fleet will be able to burn up to 50 million tonnes of oil equivalent (Mtoe) of low-greenhouse gas (GHG) fuels annually, double the estimated volume needed to meet the IMO 2030 emissions target.Yet today, actual consumption of low-GHG fuels remains at just 1 Mtoe.The widening gap between capacity…

Wallenius Marine and KNUD E. HANSEN have launched a new RoRo (roll on/roll off) design at Donsö Shipping Meet.The new concept builds on the Sleipner PCTC concept and on operational data from the Sleipner vessels Future Way and Way Forward. The new RoRo design, which includes an engine room in the bow, creates a large cargo capacity of 2,720 lane meters, equivalent to 181 trailers.The Sleipner RoRo concept allows for loading and unloading to be carried out quickly and efficiently using the stern ramp and main deck across the full width of the ship…

Around 50 vessels have operated on hydrogen as fuel since the pioneering ferry Hydra set sail in 2000.Whether it’s used in fuel cells or combustion engines, its capex and opex are still much higher than an equivalent diesel system, and it’s expected to stay that way until at least 2040.But the real problem with using hydrogen as a fuel is that it takes more energy to make, compress/liquify, transport and store than it provides to a ship.The expectation is that technology will come to the rescue.

Italian shipping firm Grimaldi Group has welcomed the second ammonia-ready pure car and truck carrier (PCTC), Grande Tianjin, from Shanghai Waigaoqiao Shipbuilding (SWS), a subsidiary of China State Shipbuilding Corporation Limited (CSSC).The delivery of a 9,000-car capacity PTCT built for Grimaldi Group also marks SWS's 600th vessel or offshore platform since its inaugural delivery, the 150,000-ton Floating Production Storage and Offloading (FPSO) unit Hai Yang Shi You 111, in 2003.The Grande Tianjin is compatible with electric vehicles…

Taiwan’s U-Ming Marine Transport Corporation has announced that its 64,000dwt bulk carrier, Asian Progress, has successfully completed its first bunkering operation of B24 biofuel (FAME B24) at the Port of Singapore.The vessel is U-Ming’s first vessel to adopt biofuel, with the company aiming to be net-zero emissions by 2050.The bunkering operation was supplied by TFG Marine, with a total volume of 300 metric tons. It is expected to reduce well-to-wake carbon emissions by approximately 20% compared to conventional marine fuel.Since 2023…

Holland Shipyards Group, in collaboration with Eureka Shipping and SMT Shipping, delivered the cement carrier Tamarack earlier this week at Holland Shipyards Group’s yard in Hardinxveld-Giessendam.Tamarack is a 12,500-DWT self-discharging cement carrier designed specifically for the Great Lakes region in Canada. Built to replace two older vessels, Tamarack offers equivalent transport capacity in a more compact and efficient platform. The vessel is equipped with diesel-electric propulsion…

Norwegian shipowner Rem Offshore has launched the hull for its dual-fuel methanol energy subsea construction vessel (ESCV) Rem Pioneer in Vietnam, months ahead of schedule.The launch ceremony was held on June 27 at Song Cam shipyard in Vietnam.According to the company, hull construction will continue for a while, and outfitting will begin in the autumn at Myklebust Verft.Rem Pioneer ESCV will be delivered in 2026 and will be the first of its kind that can perform heavy construction…

Skarv Shipping Solutions, a joint venture between Peak Group and Grieg Edge, has increased its order for ‘zero carbon project carriers’ from Shandong Huanghai Shipbuilding to five ships, extending its commitment to a Berg Propulsion package that optimizes vessel efficiency regardless of power source.Skarv specified inline ammonia-ready engines for the initial four 7,000 dwt ships, with the first ship due delivery in the fourth quarter of 2025, followed by three more through 2026.

In a first-of-its-kind intercontinental journey, a crew has piloted the Candela C-8 “flying” electric boat across the Strait of Gibraltar.The Candela C-8 completed the 24-nautical mile trip from Sotogrande, Spain, to the Spanish enclave of Ceuta in North Africa, in just over an hour, matching the speed of conventional fast ferries.

Crane specialist Huisman has secured another contract for the delivery of Knuckle Boom Cranes, which will be installed on Sea1 Offshore’s new offshore energy support vessels.The two 250 mt Knuckle Boom Cranes will be installed of ST-245-designed vessels.The contract was signed with COSCO Shipping, and follows a previous order for two identical cranes awarded at the end of 2024.The cranes will feature Huisman’s proprietary Active Heave Compensation system.This system connects the crane’s electric setup to the vessel’s DC grid…

If the dynamic positioning (DP) system went down on an offshore supply vessel, it could result in a collision. On a dive support vessel, it could result in injury or death for a diver. On a drilling rig, it could result in a blowout with loss of life, pollution and fire.Built-in redundancy is key to avoiding failures, and this in turn determines the thruster, electrical and engine configurations that are designed to enable DP systems.“There is no single, universal solution,” says Lauri Tiainen, Director Thrusters and Propulsion Control Systems, Wärtsilä Marine.

Crane specialist Huisman has signed a contract with Greek shipowner Capital Offshore for the delivery of four Knuckle Boom Cranes, which will be fitted on new platform supply vessels (PSVs).The cranes will be installed on the new MMC-designed PSVs currently under construction at the Fujian Mawei shipyard, and destined for operations in the Brazilian market.Boasting a lifting capacity of 100 mt each, the cranes are designed to operate at depths of up to 3,000 meters.The cranes are equipped with Huisman’s proprietary Active Heave Compensation (AHC) System…
