OSV Relume

Relume was commissioned in the Netherlands in 2004 and entered service initially as a light tender serving the maritime community in the Middle East. The ship quickly gained an enviable reputation as a combined offshore support / multi-role OSV. In 2006 she relocated to the North Sea area and has since been continuously employed on both short and long term contracts in the oil and gas industry and also the emerging renewables sector.

In 2015 Relume underwent a machinery and accommodation upgrade to ensure her continued competitiveness in the modern DP market. With excellent position-keeping ability, improved client facilities, increased accommodation, an AHC knuckle boom crane and enhanced deck power arrangements, Relume will be better able to meet clients’ requirements and continue to provide a safe and efficient operational platform.

In addition to her mechanical refit, Relume has undergone an extensive refurbishment of accommodation, with comfortable two-berth cabins boasting en-suite facilities. She has a spacious dining room with healthy, fresh and nutritious menu options prepared by professional catering staff.

Client facilities include dedicated recreation and conference facilities; Satellite TV; outside line telephones and Wi-Fi throughout the accommodation areas in addition to a wellequipped onboard gym facility.
