Since its foundation in 1978, Bluewater has built a technological lead specialising in design, development, lease and operation of tanker-based production and storage systems, and is a leading provider of innovative single-point mooring systems.
Bluewater designs, manufactures and supplies floating production, storage and offloading (FPSO) and single point mooring (SPM) systems for oil companies worldwide through turnkey supply and time charter contracts.
Floating production, storage and offloading systems
Bluewater has created, owned and operated ten floating production, storage and offloading systems (FPSOs), with three being retired and two sold back to oil companies.
The company also provides operational and logistic management and support for FPSO and FSO systems, and currently holds and operates five FPSOs.
Single point mooring systems
Bluewater has developed some of the most innovative SPM solutions, including catenary anchor leg mooring (CALM) buoys and tower, internal and external turret mooring systems.

Each type has its own characteristics and fields of application.
During the past 35 years, the company has created and delivered more than 100 CALM buoy systems and 25 tower and turret mooring systems, which include internal, external, fixed and disconnectable types.
CALM buoy systems
The CALM buoy system is a buoy permanently moored to the seabed using multiple mooring lines. It facilitates near shore and offshore loading / offloading of trading tankers.
The buoy contains a bearing system that allows a part of it to rotate around the moored geostatic part. A tanker moored to this rotating section is able to freely weathervane around the geostatic element of the buoy.
The fluid transfer system includes submarine hoses between the pipeline end manifold (PLEM) at the seabed and the buoy, and hoses between the buoy and the tanker.
Turret mooring systems
The turret mooring system (TMS) consists of a turret assembly integrated with a vessel and fixed to the seabed by means of a mooring system. The TMS contains a bearing system that allows the vessel to rotate around the moored geostatic section of the turret.
The TMS includes a transfer system that enables connection of subsea pipelines and equipment to the weathervaning vessel such as an FSO or FSPO. The transfer system includes risers and umbilicals between subsea infrastructure and the geostatic area of the turret. Swivel modules forming part of the turret provide the transfer paths for fluids, gasses and power and control signals.
The TMS is fully passive and does not require active vessel heading control or active rotation systems.
Tower mooring systems
The tower loading system consists of a tower structure that is permanently fixed to the seabed. The tower contains a bearing system that allows a segment of it to rotate around the fixed, geostatic part. A moored vessel is able to freely weathervaning around the fixed section of the base. A swivel in the tower provides the fluid, gas, power and signal transfer paths from rotating to geostatic.
A fluid transfer system enables connection of the vessel to the pipelines, which are connected at the base and swivels provide the fluid, gas, power and signal transfer paths in the tower.
Tower mooring systems are typically designed for shallow water depths and may include an ice-breaking cone structure to operate under arctic conditions. This enables the system to withstand ice on the move while being exposed to a temperature of up to -50°C.
The Cluster 2 fields lie in the deepwater KG-DWN-98/2 Block located off the shore of the Godavari Delta on the east coast of India in water depths ranging from 300m to 3,200m.
Tortue West gas field is located at a water depth of 2,850m in the Greater Tortue Complex, between the C8 block off the shore of Mauritania and the Saint-Louis Profond block off the shore of Senegal. It is being developed under the Greater Tortue Ahmeyim development project.
The Lancaster field is located in blocks 205/21a, 205/22a and 205/26b of the West of Shetlands area offshore UK in water depths of 160m. The prospect is 100% owned and operated by Hurricane Energy.
The Bukit Tua Development Project involved the development of the Bukit Tua oil and gas field located 35km north off the coast of Madura Island, the Ketapang Production Sharing Contractors (PSC) region, offshore East Java, Indonesia.
Bluewater Energy Services is pleased to announce the award of a contract from Hyundai Heavy Industries (HHI) for the engineering, procurement, construction and integration (EPCI) of a major turret and mooring system for the Rosebank floating production, storage and offloading (FPSO) vessel.
