Everllence secures order for 16 high-speed 175D gensets for Guyana offshore tugs

Everllence has secured an order from a Turkish shipyard for 16 high-speed 175D generator sets (gensets) that will be installed on four offshore terminal tugs being built for operations in Guyana, South America.

The vessels, based on the Rampage 6000-DE design developed by Robert Allan Ltd., will be operated by Smit Lamnalco, a Boskalis company. They are intended to support an FPSO (Floating Production Storage and Offloading) fleet operating in the Stabroek Block.

The four vessels will perform a range of offshore support functions, including towing, safety operations, logistics, dynamic positioning and maintenance.

Four gensets specified for each tug

Each vessel will be equipped with four 175D gensets comprising two 12V175D-MEL engines rated at 2,280 kW each and two 16V175D-MEM engines rated at 2,560 kW each.

The first set of engines is scheduled for delivery by the end of 2026, with the remaining three shipsets planned for delivery during 2027.

The diesel-electric propulsion arrangement will allow the vessels to operate different combinations of generating capacity depending on their operational requirements.

Smit Lamnalco cites efficiency and lifecycle costs

Jamie Stewart, Group Tender Manager at Smit Lamnalco, said the company selected Everllence based on factors including reliability, technical support, fuel and lubricating-oil consumption and overall commercial competitiveness.

“Everllence was chosen by us for this project in consideration of its reputation for reliability, strong technical support, and efficient fuel-and-lube-oil consumption, whilst remaining commercially cost-competitive. These factors, combined with increased overhaul intervals, will result in maximum in-service time for our charterer, as well as reducing our operational expenditure over the vessel lifetimes.”

Stewart added that the use of both 12-cylinder and 16-cylinder engines would provide operational flexibility while allowing the vessels to use common equipment and spare parts.

“With Everllence providing a combination of 12- and 16-cylinder high-speed 175D engines, this will give our diesel-electric vessels the flexibility to operate fuel-efficiently across various operating modes, as well as providing commonality of equipment and spares, reducing inventory costs. We look forward to many years of reliable operation with this equipment being integral to our operational success.”

175D range covers offshore and workboat applications

Ruben Fernandez, Head of High-Speed at Everllence, said the order adds to the engine platform’s presence in the tug and offshore vessel markets.

“We are very pleased to have secured this important order. It underscores the strength of the 175D and its growing success in the tug and offshore sectors. Customers value the engine’s efficiency, performance and attractive lifecycle costs. We would like to thank Smit Lamnalco for their trust and look forward to supporting their operations for many years to come.”

The 175D engine family was developed for marine applications including offshore support vessels, tugs and other working vessels. The range is available in 12-, 16- and 20-cylinder configurations, with power outputs ranging from 1,500 kW to 4,400 kW.

Additional variants of the engine platform are available for applications including superyachts and naval vessels.

175D designed for lower fuel consumption and alternative fuels

Everllence said the 175D was designed with a focus on fuel efficiency and compliance with current exhaust-emission standards.

The engine range is also cleared for operation on certain biofuels, including fatty acid methyl ester (FAME) and hydrotreated vegetable oil (HVO). This capability allows the engines to be used with lower-carbon fuel options where appropriate fuel supply and operational conditions are available.

The Guyana order will see the 175D platform deployed on vessels supporting offshore oil production in the Stabroek Block, where the new tugs will provide marine support to FPSO operations.
