Gulf Marine Services (LSE:GMS) has secured a 183-day contract extension for one of its Small-class vessels operating in the Gulf Cooperation Council region, further increasing the offshore support specialist’s contracted revenue visibility.
The extension was awarded by a major Middle Eastern national oil company under an existing agreement. It also includes two additional options of three months each, giving the customer scope to extend the vessel’s deployment further.
Following the award, Gulf Marine Services’ contracted backlog has risen to USD 659 million, providing the group with substantial visibility over future activity.
The vessel will continue supporting offshore maintenance operations for the customer without interruption. The extension highlights continued demand for GMS’s self-propelled, self-elevating support vessels across its core Middle Eastern markets.
Management said the contract demonstrates the customer’s continued confidence in the group’s operational performance and reliability. Maintaining the vessel’s deployment will also support fleet utilisation, which remains an important factor in delivering GMS’s strategic and financial objectives.
The company’s broader financial position has strengthened over recent years, supported by revenue growth, sustained profitability and continued deleveraging. However, these improvements are partly offset by a decline in net income during 2025 and a significant reduction in free cash flow.
Technical indicators remain broadly neutral, although the shares receive some support from trading above important moving averages. Valuation appears relatively reasonable based on the company’s price-to-earnings ratio, while the absence of dividend-yield support remains a consideration for investors.
More about Gulf Marine Services
Gulf Marine Services is a London-listed offshore energy services company founded in Abu Dhabi in 1977. The group operates a fleet of 15 self-propelled, self-elevating support vessels from bases in the UAE, Saudi Arabia and Qatar, serving customers across the Middle East, Asia, Africa, the Americas and Europe.
Its vessels support activities including offshore platform maintenance, well intervention and offshore wind projects. The fleet is divided into K-Class, S-Class and E-Class vessels, capable of operating in water depths ranging from 45 metres to 80 metres.
GMS vessels provide substantial deck space and crane capacity, with accommodation for as many as 300 personnel. Their four-legged, self-propelled configuration allows them to relocate between offshore sites without requiring tugs, potentially reducing both time and costs compared with conventional support vessels.
The fleet serves both operating expenditure-led and capital expenditure-led offshore projects, giving GMS exposure to maintenance requirements as well as new infrastructure and development activity.
