Wärtsilä for vessels propulsion

Wärtsilä will supply the engine and propulsion equipment for a new 3800 DWT heavy lift vessel being built for Netherlands based operator Hartman Seatrade. The owner has established a new shipyard, Rock Shipbuilding, where the vessel will be built.

The vessel will operate with the Wärtsilä 31 engine. It is available in 8 to 16 cylinder configurations with a power output from 4.2 to 10.4 MW at 720 and 750 rpm. This Wärtsilä engine for vessels propulsion can run on Diesel, Dual Fuel (DF) and pure gas (SG), IMO Tier 3 compliant when operating on gas, or with an SCR when using Diesel.

Wärtsilä will also supply the gearbox which will enable the vessel to operate in PTI (Power Take-In), PTO (Power Take-Off), and PTH (Power Take-Home) modes, thereby further improving fuel efficiency. The vessel’s Controllable Pitch Propeller(CPP) will be controlled by Wärtsilä EcoControl and hydrodynamically optimised with Wärtsilä’s Opti Design solution. Operating the propeller at low speed when full thrust isn’t needed will also deliver additional fuel savings. The Wärtsilä equipment is scheduled for delivery in spring 2027.

Wärtsilä Lifecycle Agreement for 12 New Vessels, Specifically LNG Carriers owned by MOL

The Finnish company has signed a 10-year Lifecycle Agreement with MOL Global Ship Management, a Singapore based ship management company fully owned by Mitsui O.S.K Lines (MOL). The agreement is designed to deliver operational support with reduced engine downtime and increased maintenance flexibility for 12 LNG carriers.

Gas carrier owners and operators are focused on ensuring safe and smooth cargo transport while navigating key challenges such as market instability, financial unpredictability, vessel complexity, and increasingly stringent environmental regulations.

Through the new Lifecycle Agreement with Wärtsilä, MOL Global Ship Management will benefit from increased reliability, reduced operational costs, and enhanced confidence in their LNG fleet. The integration of Wärtsilä’s Dynamic Maintenance Planning solution, alongside 24/7 remote operational support and proactive contract management, aims to ensure flexible maintenance scheduling, extended service intervals, and lower spare parts consumption.

Dynamic Maintenance Planning

MOL is a long-standing strategic customer to Wärtsilä and various ships in their fleet are supported with Wärtsilä agreements. The 12 vessels are new LNG carriers that were delivered during 2024 and 2025. They each operate with two 6-cylinder and two 8-cylinder Wärtsilä 34DF dual-fuel engines and four Wärtsilä gas valve units (GVU).
