Everllence has signed a contract with a Turkish shipyard to supply 16 × 175D gensets for four offshore terminal tugs that will operate in Guyana, South America, supporting deepwater oil production in the Stabroek Block.

The four Rampage 6000-DE tugs, designed by Robert Allan, will be operated by Smit Lamnalco, a Boskalis company, in support of a floating production, storage and offloading (FPSO) fleet. The vessels are described as performing a combination of towing, safety, logistics, dynamic positioning and maintenance functions.

Each of the four vessels will be fitted with four gensets, comprising two 12V175D-MEL engines rated at 2,280 kW and two 16V175D-MEM engines rated at 2,560 kW. The first shipset is scheduled for delivery by the end of 2026, with the remaining three to follow during 2027.

Smit Lamnalco's group tender manager, Jamie Stewart, stated: "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 vessels' lifetimes."

Stewart added: "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."

Ruben Fernandez, head of high-speed at Everllence, remarked: "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."

According to Everllence, the 175D engine range was developed to supplement and complete its product portfolio in the maritime sector. Available in 12-, 16- and 20-cylinder variants, the engine is said to deliver output ranging from 1,500 to 4,400 kW, and is described by the company as optimised for offshore support ships, tugs and other working vessels. Additional variants also serve superyacht and naval applications.

Everllence notes that the 175D was designed from the outset for low fuel consumption, and says it complies with the latest exhaust-gas emissions standards. The engine is said to already be cleared for operation on biofuels, including fatty acid methyl esters (FAME) and hydrotreated vegetable oil (HVO).
